Performance Fins - Scuba Tech Tips: S06E02

[@LarsDennert]

You should take note that the vents in Jet fins allow water through on the "down" flutter stroke (top surface of the fin) but not on the "up" stroke. Frog kicks, however, only use the bottom side of the fin. This allows a very powerful frog kick while minimizing resistance on the recover stroke. Although you might not be able to decipher the engineering that went into this old fin design, I believe there is more to it. Though companies have tried to reinvent the wheel, the wheel is still round. Water is the same as fifty years ago and so is the human body. Each tool has it's purpose. Keep the great videos coming.

One benefit of shorter fins (e.g. force fins etc) is if you do a lot of rib diving as we do in the uk. Much easier to put on in a cramped boat and less people standing on them. Great channel and love your delivery sir

[@AlecPeirceScuba_SeaHunter]

Yep! I've been on a boat with divers who have free diving fins (don't know why?). They must have been 3' long. What a pain in the butt - for everyone. The Force Fins are pretty neat. I have used and sold them. One of the best features is that you can walk on them fairly safely unlike other fins. Thanks for watching. Alec

[@mshipek]

Just sharing my own personal experience here. I was a Navy Rescue Swimmer (SAR) and we were issued those rubber jet fins in SAR School and that's what we used. I used to swear by those fins, thought they were the best design, fastest fin, etc.. Nobody could convince me otherwise. However, I have been a Scuba Diver since 12 years old (PADI 1984) and always used some of the old US Divers Blade fins before joining the Navy and I loved those two, but I was a lot younger then. Now, after using those rubber fins (Jet Fins) in the pool on countless laps for many hours at a time (we would have blisters and open sores on our ankles and feet when done every night) and also using those old Blades and the new ScubaPro SeaWing Nova, I have to admit Alec is right. I'm a very aggressive and strong swimmer and can manipulate those jet fins like they aren't there, but the other fins I could accelerate and maintain speed much quicker and longer because those other fins feel like I have greased bare feet. However, the ONLY thing I don't like about them is that they aren't more rigid, because if I kick too hard, they do fold to a point where there's very little thrust. That's just my share, for what it's worth :-)

[@AlecPeirceScuba_SeaHunter]

I'm sure you've noticed that the Seawing has notches cut into the hinge of the fin. These are on the bottom only and specifically designed for divers like you Max. With a normal fin, when you kick too hard the water just spills over the side. It's not only wasted force but it actually will slow you down from the drag. With the Seawing, the fin blade stays straight but it bends at the notches and they close. When you reach the end of the stroke and stop finning, the notches then open, the fin straightens and the force used to close them, some of it anyway, returns to push you ahead. That's the theory and it seems to work in the water too. The only fin that actually works well for very aggressive, strong divers who kick too hard is the old Frogfoot fin from the 50's. It supposedly was used by the Navy UDT divers and was about 5 pounds in weight. It simply didn't bend - at all. These were my first fins and I still have them. I don't use them. I can barely lift them!! Take care Max. Alec

[@AMaverickBrother]

Check out the Seawing Nova Gorillas. They are the same fin but made with a slightly more rigid material which might be exactly what you're looking for.

[@MatVoss]

My favorite allround fins are german Barakuda Gigant, designed in 1962. Used by german S:E.A.L.S. since then and up to now. They win hands down in any comparison with the Seawing Nova. I tested these , among others, in a pool, with stopwatch end everything, always starting with the same pulse rate and same subjective effort. The Gigant were 3 seconds ahead of the rest of the field, to my surprise followed by half a second by the Apollo Biofin (which is also the choice of our "Kampfschwimmer". I use the gigant equippped with the Apollo's spring straps.

[@MatVoss]

The Seawing Nova executes a backward force if you kick it hard in the pool with high amplitude strokes. Just before the direction of stroke is reversed. You fell it only in the pool, perhaps, when the bare skin is exposed to the water.

[@mertgul2590]

Some people say that the little area infront of the foot pocket is a dead zone that does not help you to push the water but creates some kind of resistance to your movement. So they say that these holes are canceling these dead zones and makes the fins more efficient. By the way, thank you for this nice video. Greetings from Turkey 👌🏻

[@CUCABURRAAustralia]

Great video, thank you Mr. Peirce. Speaking about fins, it is also vital to mention the two main types of a kick the divers would be using. From my personal experience, soft fins with holes or even split fins are really bad for frog kick, to perform it properly, one really needs a fin with a stiff hard blade. In this case, jet fins from Scubapro or even their replicas from other manufacturers work pretty well. Most common feature - short and wide hard blade, the design might vary. On the other hand, for those divers who prefer the traditional flatter kick or just for relaxed gliding in the midst of the water where there is no current - soft fins are also a decent choice. And please, don't get me wrong, I'm not trying to force my opinion, but sooner or later as the divers build up their experience in swimmong and buoyancy control, many of them switch to frog kick as a much more versatile and efficient style of fin kick. Several reasons for that: 1) There is "resting phase" between the kicks 2) The leg muscles used for frog kick are much stronger 3) Frog finning diver does not stir up the sediment while swimming close to the bottom 4) Higher manuevrability with all those fancy helicopter turns and back kicks 5) Looking cool :) Therefore, usually I observe an evolution, when begginners are starting their dive experience with soft fins like Sea Wing Nova and then switch to hard blade ones. Small bonus - your legs get nice and muscular while swimming in hard blade fins :)

[@alexandrerondeau]

Hi Alec thanks again Great tip! For those who don't believe that weight matters on fins. Have them go for a dive with ankles weights for a dive! They will notice the inertia and momentum rapidly! I finally got rid of my training wheels / ankles weights in order to keep air out of my legs in my drysuit and oh boy! I don't get cramp in my legs anymore! I have a question, I know your channel is more toward recreational, but could you do an episode on self-reliance system? Like H valve and ponies? Thanks!

[@AlecPeirceScuba_SeaHunter]

Years ago, young and invincible, I made many dives on a famous and deep shipwreck in Tobermory (110'/ 40 degrees). I made many dives on that ship alone! When I started diving in the 50's-60's, I didn't have a buddy so diving alone didn't bother me. However, knowing the depth and cold to be a factor, I made a 'system' that met my standards for self-reliance. This was long before "Solo Diving" courses, "Self Reliance" or the many redundant systems we have today. I carried 2 tanks (steel 72's) with a separate regulator on each. One tank was for the dive and the other was for the return (I occasionally had to decompress a little bit). I have a picture of myself just about to jump in with this set-up on my back. FYI, I did NOT have a BCD or dive computer or some other modern scuba items that add to a diver's safety today. It worked perfectly for me at that time. I only had one problem dive using it and that was of my own doing. I suppose looking at it now it was similar to an H valve (allows 2 regulators) only it had a separate air source for the 2nd reg. The point is that today divers have many options in terms of redundancy. Each has it's own advantages. Each has it's own peculiarities too. I suggest research or better still, a course on Self Reliance, would be the best source of info on what to consider. Alec

[@travpell3395]

I would really like a tech tip on drysuit maintenance. How to keep if from needing repairs quickly & what the testing is that is done during the checks by my LDS. Thank you.

[@DamianBaranPL]

Not that it matters nor i am even close to Alec's experience but he is 100% right. I personally use Scuba Pro Seawing (white fins in the video) and i did use Jet Fins before. Once on a single dive, i exchange fins with my buddy who does have JetFins .... the difference is immediately visible. You feel a different weight (JetFins are much heavier) but that's not the biggest difference. Efficiency in Seawing is just incredible compared to JetFins. The only issue i have is when swimming backward. Seawing is messing up your trim due to its design but other than that you can do any style you want. 95% of a time i use frog kick and despite from what one of my instructors said when he saw these fins for the first time, these fins are perfectly fine for the frog kick. Last but not least Seawing weight makes it perfect for traveling.

[@AlecPeirceScuba_SeaHunter]

There's no logical reason that the Nova wouldn't work perfectly for any fin kick. It is pretty much a standard fin design aside from all the sophisticated features - lightness, efficient design, snap-back feature, blade, pocket, strap, etc. Anything a diver can do in a Jet he can do in a Nova - just with less effort. Gotta' be good! Alec

[@DamianBaranPL]

Hi Alec, Thanks for your response. I think the problem (at least for me) is the shape of the side of the fin. Jet fins have a straight shape and Seawing has curve shaped side. Sides are used for propulsion in the backward swimming and for me personally, it causes head up effect. But i guess you're right, practice is the key ;-) Also, the effective side area in Seawing is much smaller than Jet Fin. I'd still recommend Seawing for recreational divers regardless of this.

[@KimonFrousios]

For cavers and wreckers the old fin might have an appeal for a very simple practical reason: length. Long fins are great for open water with lots of room for kicking but in tight spaces a shorter blade gives your leg more wiggle room before the fin impacts the environment. I'm tall and my fins are fairly long and this is a recurring issue in my dives. Not enough that I'm planning to replace my fins, but enough for me to be self-conscious about it.

I can understand what you explain about the angle and inertia. I felt I with my Jetfin Revo. However, we tried the Nova, it doesn't work well with frog kicking but performs well with flutter kicking. I personally found my best fit with the Dive Rite XT. It has a curve but it works great with frog kicking. Since my Jetfin Revo remained in the box. I also have a pair of Hollis F2 that are my travel fins. They work well but not as well as the XT.

@@AlecPeirceScuba_SeaHunter my buddy loved the gorilla nova. He said they were stiffer than the Nova and he liked it a lot but gave it away after one of the fins caught a fish like (we have tons of them there and actually he got caught again yesterday by a fisherman's hook as we were diving together). One more point, we tend to prefer fins with metal spring straps over rubber ones for longevity. When you dive every week, it's important I think. My two cents...

[@xentrix1024]

Fantastic video! Is there any research, review or manucturer provided data on fins' efficiency? I think that an interesting metric of efficiency would be the percentage of the propulsion power, according to the provided power, ie how much of the power you put is pushing you forward.

[@danielmewes]

There are a few published papers on this: "Evaluation of fins used in underwater swimming." archive.rubicon-foundation.org/xmlui/handle/123456789/3936 "Energy consumption during fin swimming" archive.rubicon-foundation.org/xmlui/handle/123456789/9790

[@xentrix1024]

Thanks! These are very interesting, especially the first one, which is more recent too. Apart from the research methodology, I would like to quote a phrase from the discussion at the end of the paper: "In our studies, the divers invariably ranked the stiff fins as the best and the flexible fins as the worse, which did not correlate with the objective evaluation of these fins." Veteran divers' bias...

[@whynottalklikeapirat]

The inertia with the jet fin is only a problem if you extend your thrust all the way with it and the stop abruptly. It is true that it takes some effort to get the blade going, but once it does you don't follow through and "stop it". You relax your lower leg and ankle before the stroke is fulle extended - and allow it to continue with it's own momentum and that's when you get a strong push for your buck as it straightens out on its own, and at that point it is precisely the weight that assists in the transfer of power. THEN when that "rebound" effect is complete and you have allowed for gliding you begin your upstroke, and you do that not as if the fin was nailed to a plank and jutting straight out. You allow your ankle to bend so that initially you are not even working against the water but just pulling the fin and building momentum and the blade begins to bend as you gradually straighten the blade and the momentum actually assists you in that push and the fin bends, just like before and you stop moving your leg and allows the fin to finish on its own and you glide and then begin your next downstroke, soft at first and then strong, and then let go and let the fin work, and glide and pull back the fin at an angle to minimize resistance at first and then move into the thrust strong and allow it to complete on its own. I do not deny that these fins require some muscle power to get this technique going, but once you master it and are not just hammering away at the water like your leg was a wooden oar - you get the benfit of that rebound and you get a lot for what you put in. Sure you have to build awareness of how to work the turnaround for each position with minimum effort so you handle the weight intelligently. That takes feel and timing and that needs to be trained until it's automatic even in dynamic water. But then again this is about the alternate kick approach which I don't use much anyway. But that's how I do that when called for. Frog kicking you have the strongest muscles in your body assisting that backward push and the rest is just pulling back with as little water resistance as possible. FOr this purpose I find that it is exactly the weight that puts force into even small movements allowing you to manoeuvre strongly but with precision even with small movements. I love the organic feel of that - but you have to develop an organic finning style to go with it, and a certain amount of physical base strength to maintain it. But then you get something extra for your effort, exactly by exploiting weight and velocity in a strategic balanced way.

[@kaeptenxy3569]

I love my Jet Fins. I had other before but the Jet Fins are much better, you will never brake them and the weight is quite useful when diving a drysuit, also with a proper trim horizontal feats up and fins parallel to the surface there you don't want a bent fin, also if doing a frogkick they are perfect, oh and they come in all different collars now

[@AlecPeirceScuba_SeaHunter]

Wow! I didn't know they had colors now. As I've said many times, if it works for your and your diving, stick to it. You comments about weight trim and angle (depending on the kick you're using) make sense. Alec

[@travisjohnson6676]

I have old school style Aqualuus Superjet rubber fins which have the three "holes" and they do have a purpose. On the power stroke, the angled shape of the foot pocket directs water past/across the holes so power is not lost but on the weaker recovery stroke water flows through the vents basically making that stroke easier

[@AlecPeirceScuba_SeaHunter]

That's what they say. I have used dozens of different styles with "angled holes" or "special jet holes" and have never felt a difference. I think a hole in the blade of a fin will reduce the power stroke. Maybe I'm just not sensitive. My 3rd wife used to say that. Take care. Alec

[@amadeuss3341]

Holes there to prevent flow separation on the low pressure side of the blade, cause it will result in increase drag. Meanwhile the hole on those new fancy fins is to hang them on the wall nicely, since it's major pain in the butt to store the fins

[@AlecPeirceScuba_SeaHunter]

That works too! Thanks for the info and bike safe. A

[@amadeuss3341]

@Alec Peirce Scuba glad to help. Thank you for your videos, a lot of great information

[@dburlage4]

Alec great presentation on the fins. However I would like to point out that with the jet fin and technical divers, especially wrecked and cave divers they do not fin using a traditional scuba divers fin kick (up & down). All properly trained cave and technical wreck divers exclusively use a frog kick only which does not lend itself to your argument about momentum and inertia as the fin is not moved up and down just open and closed like a frog. Consequently, the standard jet fin design lends itself affectively for this type of finning style. Aside from that, I really like what you say about the new SCUBA Pro fin and will try to pick up a pair and give them a try for non-technical dives. Oddly enough I started diving in 1968 when I was old enough to do so, and have continued to dive ever since I love the sport and love your show. I would like to meet you someday to chat about diving.

[@AlecPeirceScuba_SeaHunter]

I think you're quite right. Clearly, the laws of physics do not apply when fin movement does not involve acceleration or starting/stopping. I think the Nova fins will impress you and I also think they'd be good for the frog kick. Some tekkies say they like the old rocket fin because it's heavy. The leg muscles are the largest in the body and take prodigious amounts of oxygen. Why would you load up those oxygen-sucking muscles? Add a 2-pound weight to your belt and use a modern, efficient and light fin!. Alec

[@dburlage4]

​@@AlecPeirceScuba_SeaHunter Your analysis is sound as usual. I will try to locate a pair of rental ScubaPro Nova fins and give them a try. Also, recommend you try the new www.deep6gear.com, Deep Six fin which is a re-designed version of the jet fin. Much lighter, half the weight of the jet fin with a deeper/wider foot pocket. The LG size is only 21.25" (fin tip to heel of foot pocket, weight 35oz).

[@sumdarkplace]

So I am a Physics major, with a Masters in engineering. Most of what you say is correct, however, as others have pointed out, your analysis only considers flutter kicking, and also does not take into account fluid dynamics of flow close to the foot. A big, flat, stiff blade will give better all round performance for fine control and variations of kick style. A long, curved, flexible fin is almost useless for modified flutter, such as moving in confined spaces, as the flex absorbs the small movement without efficiently transferring that energy to forward motion. For frog kick, any fin designed to be ultra efficient on the flutter downstroke is going to be at a disadvantage, as the powerstroke of a frog kick works on the opposite side of the blade. Your analysis on the inertia and momentum is spot on though. This is why a number of manufacturers are currently producing copies of the Jetfin constructed from modern, lighter materials. Ultimately, fin choice comes down to both the type of diving you do, and personal preference. I love my jetfins for diving, but use a light, flexible fins for snorkelling. My wife uses the Seawing Novas (also in white, with a white wetsuit!), as they suit her. Also a factor is that we don't often travel to dive, as we live on Grand Cayman, so luggage weight is rarely an issue.

[@nikita-jade6700]

Hi Alec, Thank you for the brilliant review. It is incredible that 50 years later, the Jetfin is still a favourite (as I can see by the older comments). I have heard that muscle strain and cramping was an issue with older fins, like the Jetfin, that do not have heel support, do you agree?

[@AlecPeirceScuba_SeaHunter]

Absolutely. Fin-makers in thew '50s and '60s did not have any technology to measure power and thrust much less impact on the diver's foot. They simply drew a fin that looked good and made it. Today a manufacturer spends hours and a lot of money to ensure the fin will do what it is supposed to do. One very important development from that is the fact that the diver's foot must be supported right to the heel. The early fin design (Rocket, Jet, +) ends at the instep so the foot is forced to bend on every hard kick. That is painful and requires a lot of extra effort to overcome and that efforts wastes oxygen and causes cramps. Most modern fins have a platform that extends to the heel. There are many other innovations that have made the modern fin so much better. But, the old "it worked for my instructor so it's good for me" attitude takes a long time to dispel. Alec

[@smc2440]

Alec, Nice VDO, and it caused a huge debate among divers (lol). I think it's all about divers' choices here, and that depends on divers' preferences and types of diving they will be doing. I do believe, not scientifically proven, that holes in stiff rubber fins is there to let water through so to reduce drag caused in those areas. So it isn't actually "jetting" the water through. And yes these stiff fins won't "whip" to store and release diver's energy. But the stiffness of the fin offers better control over the blades for multiple kick styles. Heavy fins are suitable for drysuit as it could contribute to reduce risk of runaway ascent. Shorter blades also contribute to maneuverability in tight spaces as well. I also do believe that if I have to fly somewhere to dive and weight restriction comes in; then the lighter fins in much more preferable; lightweight open heel or just a pair of nice fullfoot fins. I agree that fins with tall ribs move water more effectively, totally agree with that, so it doesn't matter if it comes in a rib wall or fins winglet; as long as it keeps water inside the fins and pushing it backward. Split fins isn't my thing, but I know if I don't have strong legs then split fins may help me move through water better. I feel that it uses less energy for each kick so that I can flutter faster in the water. I had a pair of Scubapro Seawing Nova as well, and I loathed it. Yes it produces extra whip, then you have to kick hard enough for those hinges to store energy. And it performs other styles of kick poorly; of course I cannot entirely blame the fins for my skills. It just that other fins works better under my condition. Moreover, composite material fins are weak to direct sunlight exposure, forgot to put it under the shade and it will deform. Rubber fins are more rugged to abrasion, wear, and tear. I use all these factors in decision making. Most of the time I do relax, kick-and-glide frog kick. So some of the fins in the market won't fit my style, but may good for others. So I can't say explicitly which one is the best, but I can say which one is suited me best. I didn't dive to go fast - I dive to enjoy it. Keep releasing great videos! :) Ok stop debating, go diving - the one you have is your best fins ever :D

[@ParkourEh]

If I recall correctly, the tests companies do showed that the portion of the fin directly in front of the foot moves water vertically as opposed to backwards (when flutter kicking) and doesn't channel much of that water much into propulsion. Basically you're encountering resistance of the water but it's not translating into significant additional finning power; energy is lost. The holes reduce this resistance. The Seawings apparently maximized the useful surface area of the fin while cutting out the surfaces which do not translate into propulsion. It makes sense but I wonder why this principle hasn't crossed over into freediving fins if efficiency is concerned.

[@danielmewes]

Very informative video. Do you have any thoughts on fins for alternative finning techniques? I hear that the stiff jetfin-style fins are better for things like the reverse frog kick. I have been diving with Mares Avanti Quattro fins so far, and they work great for flutter and frog kicks, but I haven't been able to do a reverse kick with them. Though this might be because of my lack of technique I now got into a drysuit, and had to get fins with larger foot pockets, so I picked up the Hollis F1 (heavy, black rubber jetfins). I haven't tried them in the water yet.

[@huuhaa9038]

It's partly question about techniqe. In tropcs I use my full feet Avanti tres which are quite suft fins. I have no problem to do backward kick but I have to say it is harder than with my JetFins I use with dry suit when doing tech dives. Doing backward kick with softer and longer fins requires patience and practising.

[@Hark3n]

Hi Alec. Great video, as usual. I have to somewhat disagree with you. I've tried many different types of fins, from splits to more classic looking fins. My last pair was the Cressi Frogs. Unfortunately they snapped just before the toe. After much deliberation I got myself a pair of Jet fins. Wow, what a difference. Our dives are mostly in heavy kelp, and in between rocks, with quite a bit of current die good measure. With the jets I'm finding it much easier to navigate between the kelp, and the stiffness means that when I kick really hard I'm able to easily move against even the strongest of currents. Maneuvering with them is also much easier, as a reverse kick has pretty much the same effect as kicking forward. As for effort required, I feel that I'm expending less energy than with other fins, especially splits. I would gladly recommend jets to anyone looking for new fins. I know not everyone will have the same experience with them, but for me they are perfect. Keep up the good work. From cold and windy Cape Town, cheers.

[@AlecPeirceScuba_SeaHunter]

Hey. I'm going to be in Cape Town in November!! Keep the Great Whites hungry until I get there OK? As I often say, don't just blindly follow another person's advice. Use what works for you. There are dive circumstances where Jets might be the best choice for a diver and you've found one. Frogs are usually pretty good. I sold a lot of them. If yours broke, Cressi will replace them. And I agree on splits as you see in my vid. So how do we meet up in Cape Town? I fly from Toronto to Amsterdam to Cape Town International arriving at 11 pm on December 10. I'm there for 3 days. Alec

Both are heavy as can be. I just pay my bag fees. if I hurt my leg they beat me up...... both are the wrong choice for my kids...

[@steveaustin9386]

Alec, you kind of contradicted yourself regarding the holes/ vents in the Scubapro jet sports saying there was no definitive evidence there was any benefit to them. When you were talking about the Scubapro Nova's you said that Scubapro are a great company and spend a lot of time and money on product development, so don't you think they afforded the same time and effort on the Jet sports? Cheers.

[@duncannairne826]

The holes in the second fin are not so much vents as i the first, they are an extension of the fin while saving (weight) on material. Result is a longer fin with more propulsion benefiting leverage, at a lower overall weight.

[@AlecPeirceScuba_SeaHunter]

OK. Alec

Alec, the SCUBAPRO Seawing’s are not negatively buoyant. They float. The problem with these fins is that during a descent, they give you “floating legs”. Great fin, but they need to work on the materials.

[@AlecPeirceScuba_SeaHunter]

Not sure. If they do float, it can't be very positive. I've never tried to float them on the surface nor been affected by their 'positive' buoyancy. I think the Gorilla version must be negative. Alec

[@OSemeador]

Hi Alec, Let me start by saying that I have limited experience diving, about 5 years, with approximately only 200 dives, I am also still young in my 30s and relatively fit. I use one of the newer models of the Scubapro JetFins, and I had 2 other pairs from reputable brands of which I don't even remember the model or brand anymore. Like you, I've always been sceptic about holes in fins, to me it always sounded like a waste of potential energy. However, I simply love my JetFins and my dive will be ruined without them. As was the case when the airline erroneously sent my gear halfway around the world and I had to use one of those blue Atomic fins you showed in the video. The downgrade was so substantial that I wasn't having fun anymore underwater, I was fighting with it instead of gliding through it. Now just because this was my experience doesn't mean everyone will have the same opinion, I absolutely respect that, to each their own. A few things I like and dislike about my Jetfins: The good: - The build quality: One of my previous fins had the strap break mid-dive, not to say this won't happen with a JetFin but It hasn't happened with me so far. Also, I use the rigidity of the fins to protect more sensitive gear when in the gear bag as bags tend to be thrown around before and after flights. - The control: I can do very precise adjustments with my JetFins that I wasn't able to do without. This is extremely helpful for my macro underwater photography when I have to keep the camera VERY steady without touching anything around me (Definitely don't want to touch any of those beautiful and essential corals). Doing manoeuvres such as quick and precise rotations is also very easy. - The short length: This has been a very nice feature on those last steps on the boat before jumping in the water. Everyone is walking like ducks and I tend to have a much easier time moving around with my fins on, especially on a boat where the space is at a premium. It's also helpful to a limited extent when doing penetrations as it reduces my overall length by a little bit compared to other fins. The bad: - Heavy: An issue if you're trying to keep the weight down when flying. - The price: When comparing the price of JetFins to other fins you'll notice JetFins tend to always be more expensive. - Only for Scuba: You will only be able to use these fins for scuba due to the position of your body and the way you kick the water. I used my JetFins while snorkelling and although they do the job, I wouldn't recommend it. Another thing I would like to point out, that I think is very important, is that I normally swim doing "frog kicks", similar to how you'll do when diving in a cave. After "kicking" I bring my leg "back down" in a way where the side of my fin cuts the water. This takes very little effort as normally gravity does the job for me but I cannot say it doesn't use any energy as I'm sure it does use some. I would also like to address a point in your video where you mention the area of "lower pressure" and spillover from the side. Wouldn't the JetFins "Jet" holes send water to those areas normalising the pressure and reducing spillover? This is just my theory from what you said in the video, I'm not qualified in any sense to prove or disprove any of this. Anyways, thanks for the video, it's an oldie but a goodie. I'll try to give it a try at least once to those "new" scubapro seawing nova gorilla fins, who knows, they might be really good as you say.

Hi Alec , huge thanks and big applause for all the effort and time spent in your channel . I have recently finished my advanced open water certificate and was looking into buying a new pair of fins. I was thinking about the apeks rk3 HD but still not sure if it would be the best choice given that I am into recreational diving only . I have came across very solid reviews about it but though to know your thoughts about it. Thanks .

[@AlecPeirceScuba_SeaHunter]

OK. You asked my opinion and at the risk of irritating some divers, here goes. In short, NO. I don't think these are the best choice for a recreational diver. Actually I'm not sure who would benefit from a stiff, heavy fin with outdated design and old-style stretch straps. Let me explain my rational then y'all can blast me. The design is a direct copy of the Rocket from the 60s. It is outdated and proven to be less efficient than a modern design. Heavy and stiff almost invariably means your air consumption will increase so expect shorter dives and sore legs. Forget about the premise that the extra weight reduces the amount of weights you need to carry. In fact, you have exactly the same amount of weight on your body (as required to maintain proper buoyancy) but some of it is now at the end of your big muscle legs where it has to be moved up and down throughout the entire dive. Weight should be distributed along your torso where the only impact is to maintain buoyancy and ensure proper trim. Would you carry your weight belt in your hands while diving? So why put it on your feet? And the spring straps are heavy, they corrode (Stainless Steel is NOT stainless!) and they pinch. New stretch strap designs are a bungee-style and work beautifully. Don't be swayed by all the hype from the he-man crowd (I've been there and am embarrassed about it!) or the claims of "military approved" or other such ratings. Military approved means that you can use them but does NOT mean that the military buys them for standard issue to Navy divers. Read the advertising hype carefully. It says "based on one of the first vented fins sold in North America". As I say, an old, outdated design that does not take advantage of modern materials or modern fin development that was unheard of 60 years ago. It also says" This design has been the standard gear issue fin for ...". This design - not this fin!! There's more but that's enough for now. I suggest you go to your LDS and look at some newer find styles in new materials. Take your time and try several before you decide. A good pair of fins will last you for many, many years and will enhance your diving experience not become a challenge to be met every time you get wet. Just my thoughts. Thanks for watching. Alec

Alec Peirce Scuba none the less to expect from the Guru . Totally appreciated Alec and thanks alot for your advice.

[@kadrik0]

What are your thoughts on split fins? I love my apollo bio fins. So little effort, power, and really helped with my air consumption since I'm a 2xl 6ft 3" guy. Sometime I need to try those new scubapro fins. I've heard a lot of great reviews but man do they look like odd fins.

[@teeemotee]

Hi Alec, love your stuff. What about alternate kicking styles? More advanced divers tend to prefer frog kick as I'm sure you know since it's more energy efficient and doesn't stir up the samd when you're near the bottom. this is where the jets and jet like fins shine...though admittedly the vents probably are unnecessary for that too.

[@evenhandedcommentor6102]

You don't mention full foot fins because this is scuba and most everyone, including myself, wear boots while diving. However, when snorkeling I've compared the same model versions of full and open heel fins, and what I found is exactly what you describe about the effects of fin weight. I'm faster and kicking is easier in full foot fins. Not only do full foot fins weigh less than their open heel versions, but you also lose the weight of the boot. Of course, while fit is important with open heel fins...it's even more important with full foot fins. I wear socks inside my full foot fins, but the fit has to be near perfect.

[@AlecPeirceScuba_SeaHunter]

I have often recommended divers wear a thin sock inside their Full Foot fins. Not only does it save irritation from the fin but also from sand. I certainly like the low weight of Full Foot fins but they seldom offer the same power. If you are swimming fast or against a current, they don't always measure up Take care. Alec

[@widget3672]

I know that when I got my first fins, I asked around the local dive store and at the marine research company I was interning at and they all said the Apecks RK3 was pretty much just a scubapro jetfin but much lighter and more efficient. When I got them, I found that I suddenly had to start really using my leg muscles because I had so much more traction on the water! I also tended to have sinking feet so with some new 5mm boots and some RK3s - I found they floated despite the metal springs in the heel straps. Going from scubapro fins that don't have the rib-flexing to these was like going from a more efficient swimming style to nearly running in the water! Frog-kicking can take me over a meter forward in one stroke!

[@AlecPeirceScuba_SeaHunter]

The RK3 looks just like a Rocket fin or Jet fin. They pretty much say so in their literature. The difference is that it's made from a modern synthetic material (there's no such thing as thermoplastic rubber. It's either rubber or it's not). They are lighter for sure. Try an ankle weight. Good luck. Alec

[@widget3672]

@@AlecPeirceScuba_SeaHunter whatever the material, I just remember every time I went snorkeling or diving from the shore, if I put one down to put the other on, it'd float! I don't know much about plastics, I'm afraid my science isn't in materials, but all I can say is I liked them from the moment I tried them on (I think I was wearing them in the morning I got them so there's a picture somewhere of me eating breakfast with my fins on). If there's one thing I've got to admire about your channel, it's that I've never seen a question go unawsered! Can't say I've seen that from many others and certainly not on the level you show. I tip my hat to you sir.

[@TheRedbaron11]

Hello Alec. Love your videos. The holes at the base of the fin are there to relieve some of the water trapped there. That section of the fin does not contribute a whole lot to propulsion but adds a lot to the effort required. If you had a fin hooked up to a machine, it would definitely produce more propulsion without holes. The holes are a sort of trade off. Speaking from education and industry experience in aerospace. Lot of the concepts of aerodynamics can cross over to hydrodynamics so i should not be too far off. I have a question about the kick styles used in scuba. Most people seem to suggest frog kick is better. But i find most pricy/innovative fins optimised for flutter kick. What's going on with that? Thanks

[@MrFelipeHikari]

True! Most find are designed to flutter kick. I haven't see any manufacturer video testing the Dynamics on frog kick.

[@oneworld3719]

Hi Alec, my husband just bought Scubapro Seawing nova fins and he was amazed how good this fins work for him. Now I start to feel worried... because I have Twin Jet Max also from Scubapro. I would love to hear your comments about ' Split fins ' regarding in a strong current? is it possible to used split fins swim thru a current?? Thanks a lot and we love your Tech tips pretty useful !!!

[@AlecPeirceScuba_SeaHunter]

Good to hear from you. As I mentioned in the vid, the Split Fin was designed to bend when pushed hard and trap the water between the outside ribs. That would direct the water through the split and out the back end, adding to propulsion. It was a nice theory and works pretty well - until the fin is pushed hard. Then it simply bends too far because of it's soft center and you simply don't get the push desired. The water, still trapped somewhat between the hard outer ribs, does flow through the split but rather than shooting backward, it squirts out at right angle to the fin - basically up and down instead of back. There is just too much water flowing through the split for all of it to go backwards as it's supposed to do. Not only is this a waste of effort, that water flow actually slows down the movement of the diver. When finning slowly and strongly, the Split Fin works well. When pushed, it falls behind - splits up you might say! Not the best for currents. Now I'm bound to get negative comments from all the split lovers out there but I'm just explaining what happens. If you're a split lover and your fins do a great job for you, don't change. I think you will absolutely love the Nova. It's particularly good for anyone with legs that are not built like a football kicker - mine and hopefully yours! Soft kicks in a gentle sea or hard kicks in a current - it's like the Energizer Bunny - just keeps on going! Thanks for watching. Alec

At an Automotive Flea Market this past weekend I saw my first car - a 1954 Buick Special. I loved it too but wouldn't buy one and I'd certainly not drive it today. The Jet fins and that car are the same age. Things change with time and that's a long time Bill. You perhaps should at least think about it. See if you can borrow a pair of Scubapro Nova fins for a dive. You can use the Modified Frog kick, the regular Frog kick, the Backward kick, the Sideways kick, the 'Outa' This World' kick - or even the Flutter kick with less effort and more force. Don't take my word for it. Try it. They may not be for you but I'm sure you'll be impressed. Take care. Alec

There is an explanation for the holes: so many divers never learn how to use fins. So they knee starts to hurt. With holes less resistance less pain

I like to use the fin hole to hang mine on a nail. It works. A.

[@wildbestia]

Definitely great vid, except.... It's mass, not weight. Weight is force. Momentum is a product of MASS and velocity. The inertia and momentum of the fins are so tiny compared to inertia and momentum of the water they push, that it's practically unnoticeable. Of course you can say "multiply that by the number of kicks". I'll still say the difference is tiny, because you will have to multiply the mass of the water by the same number. Regarding of the holes in the fins. The same reason as why dome parachutes have holes on top: stabilization. Of course how big is the effect is arguable, but there is an effect.

[@rgorji]

[@tihomirrasperic]

Excellent video, can you explain the difference between the length? Some fins are short, and some are almost a meter long

[@ChristosBassCovers]

actually, mass is not weight,. Weight includes gravity which is reversed by buoyancy,. Mass is independent of gravity and buoyancy. Hence, no matter how much the buoyancy make it seems lighter due to rubber buoyancy, the mass is what is in momentum. You are correct about the inertia since it is based on mass. The more massive (independent of weight/boyancy) a fin is, the more inertial it gains in movement. Your point is still correct... Good point...

[@europana7]

Gerrit Leman very true for frog kick. First thing I noticed is it felt odd for frog kicks when I first got them way back when they just came on the market. I think the hole on the blade tip is more for convenience to clip your fins onto a carabiner and hang from your BCD D ring. ... especially for beach dives when you want to keep your hands free.

[@wearetherandombros7782]

Well Alec.... Most of the times i agree with you sir. But Seawing Nova are probably the best fin for divers that they just do recreational diving... Frog kick , back kick , helicopter kicks are NOT possible with seawings believe me it was really painful for me to sell a 200 euros fins after 3 dives because on sidemount they are useless. Also, scubapro and Apeks proved that the holes does have a reason. Beacause you wear a boot that part loses its flexibility. It needs to be strong to support the boot. So is creating more of a drag than helping. If you search it a bit you can find the testing with painted air that shows that. Also weight does matter. Apeks Rk3 soft edition are terrible with a Dry suit. Thats why the made the HD version. Dry suit need stiff fins.

[@AlecPeirceScuba_SeaHunter]

I've not tried back or helicopter finning with the Novas but had no problem with the frog kick. Re proof of the value of the holes, that "proof" has been floated for over 40 years with entirely different rationales every time - invariably by companies that sell jet-style fins. The proof never sat well with me and I used Rockets for about 20 years so know them well. I don't disagree with you. I DO disagree with the "proof". The weight of the fin can be a factor all right. It may be hard to grasp why the fin weight is a factor while wearing a dry suit versus a wetsuit but it is because a drysuit has more buoyancy in the leg. Divers often find they have to fight to keep the fin level. Ankle weights can help but I'm not a fan of them unless there is no other solution. Stiffer fins when wearing a drysuit?? Only if your leg can handle them. A drysuit may have more drag in the water so a stiffer fin might be beneficial but only if you can drive them without a problem. Otherwise, simply accept that you will be slower in a drysuit. Take care. Alec

I ended up getting a pair of the white fins as loaners until the yellows I wanted arrived in my LDS. Ended up keeping the white because they are SO much more visible.

Hi Alec. I LOVE your videos. I have a question. I respect what you said about fin qualities as a means of forward propulsion. As a photographer (and future tech diver) I need to be able to back up with my fins......I have been told that the wider side walls on the older style fins make them ideal for this. Is the new Scuba Pro you showed as good? If you could talk about finning styles for backward motion it would be most appreciated. Thanks.

[@AlecPeirceScuba_SeaHunter]

Finning backward is more a function of proper movement than fin design. That is, within reason a diver can fin backward with any fin if he does it correctly. Having said that, some fins are not quite so good - split fins come to mind. The Nova has high, strong side ribs so it ought to be good. It's also much lighter so you should be better able to control the motion. You really have to try them to know for sure. Good luck. Alec

[@MrTerryabel]

Thanks Alec. I am going to give them a try today. Much appreciated.

[@k956upg]

The whole fin requires effort to move in water but not all areas of the fin produce foreword momentum..the sides spill reducing propulsion & the tip causes a vortex that pulls you back..the area in front of the foot pocket doesn’t channel as much as the fin bends but it still causes up/down resistance to finning wasting effort & air...so the tip gets a relief hole the sides get channel lips & the foot pocket blade area gets relief holes to channel water back or let it pass depending on what part of the stroke cycle your in.. This is why I like them white Scubapro fins as they concentrate the blade surface away from foot pocket & have the most features required to eliminate negative hydrodynamics...I have all sorts of fins I use force fins in wrecks or small ribs I use aqualung slingshots in sea mostly (they get caught in line though but are noticeably the best fin I own) & I use splitfins in quarry’s (as there useless in a current but I do love them in still water for cruising...any more effort is wasted though so strictly cruising fin).

Hi Alec, Ive used Jet Fins for many years (I'm as old as you are!) and liked then very much. I recently bought a pair of the Novas and took them on a six-day dive trip to Cayman. Some observations: definitely comfortable, great heel strap, great forward power with less fatigue. However, I found them cumbersome for maneuvering - they seemed to resist quick changes of direction that I needed to quickly get into better position for photos and filming. I also did not like their positive buoyancy. they had a tendency to lift my feet when horizontal and generally upset my trim. The buoyancy may also be impacting the maneuverability issue. I suppose you can get used to anything, but I never had to wrestle with fin issues like this before. If Scubapro offered a non-buoyant version - I think it would be ideal. Thoughts?

[@AlecPeirceScuba_SeaHunter]

The Gorilla version of the Nova might be slightly more negative. Personally, I have never had a problem with their lighter weight. In fact, both for travel and in use, I love it. The saved weight when traveling is worth it. I also haven't noticed an issue with sudden maneuvers. Perhaps that's because I don't make sudden maneuvers. I think you might find that issue will disappear with more practice. I'm glad you like them though. I'm sure your fellow divers are impressed too. Alec

Hi Alec, I was wondering, what's your take on frog kicking? Around where I live many recreational divers (including me) use it, not in caves (I'm not a cave diver, not by a long shot) or wrecks but always in our "round of the mill" open water dives. In my particular case I guess I started using frog kicks because I watched my instructors use them most of the time, I've got used to them and I find them to be a very relaxing and efficient way to move around in the water. I use regular fins BTW, not the "vintage" rubber ones.

I am the opposite to you. I grew up watching Mike Nelson on Sea Hunt and he used nothing but the flutter kick. On my scuba course in 1962 I saw nothing but the flutter kick.

I have tried to use the frog kick but with limited success but many divers use nothing but and they seem to get where they want to go. Alec

Hi Alec, my name is Clancy and I'm currently new to diving and was wondering about the pros and cons to the new i3 system compared to the traditional low pressure inflator over the shoulder? I am curious about the difference in maintenance and durability of the inflator system. Looking forward to see your advice thanks.

[@AlecPeirceScuba_SeaHunter]

I love these questions that always get me into trouble. 1. the i3 system is not new. Several companies over the years have tried to increase their market share by introducing a 'great, new, inflate/deflate system that eliminates the over-the-shoulder hose'. Currently it's US Divers with their i3. None of the others, which BTW were remarkably similar, have lasted. 2. the system does not work well in cold water (thick gloves). 3 the system does not provide a visual indication that air or the amount of air is coming out. 4. the systems have proven to be a service problem requiring a lot of time, money and specialized parts to service. 5. it is not modular. If it is faulty, the entire valve mechanism must be removed, serviced and replaced while the standard system has 3 parts - PIV, hose and dump valve. Each part can be quickly removed and replaced by the diver. 6. it cannot easily be used by the left hand if and when required. 7. it is not easily identified and deployed by a buddy or dive leader in an emergency. 8. eliminating the tried-and-true standard BC hose and inflate/deflate valve is not a good enough reason to consider it. 9 USD has a history of introducing proprietary systems and parts that require you to deal with them only. Most of those systems are now defunct so divers with tme have had to replace them with standard systems. In my opinion, USD divers and dealers are the only beneficiaries of the i3. As always, I suggest if you like the idea that you try it first. As a new diver i think you ought to use and get quite familiar with the "standard" system first. I don't know if this helps or confuses. Thanks for watching. Alec

I think this episode is very interesting and "popular".. I have and use the Scubapro TwinJet Max which I love, though I have no referece to compare with, so basically I do not know what is better, hense the importance of such topics or discussions. I dive a lot with "tech freaks", I use this term all in good fun! But guys that think they are more professional just because they ware double tanks, long reg hose setup and oh yea the mandetory jet fins, might not be the best example or solution to selecting fins. Arguable they do look fantastic, very peak performed when it comes to boyency and drag. Pretty much cool looking is my opinion!. With that in mind I also noticed their fins, jetfins normally and here is why I believe they chose to use it. FROG KICKS pure and simple, also mentioned in this comment section below.. Well for wreck, cave and or plain old reef glacing, it seems to be the up most technique do use. Especially for slow moving action. I try to learn it myself, but I have found that my fins are not perticular suited for it. So it was just after watching you're first episode on fins back in season 3 I learned about the Seawing Nova fins. Moved onto watching the Scubapro's show off video over at Boots convention, just to realize those were the ones. While jetfins may mimic the image of the hardcore UDT/Navy Seal type of "frogman" look however cool, it may not be as efficiant in a heavy current or pulling a tiered diver on surface. For that I think the Nova might be more efficient. When they also can do all types of frog and fluffer kicks (or what the heck it all is called again), then I am sold again. But for slow "videography", "photography" or wreck, tech cave diving things, I think the jetfins or force fins might perhaps be more suited... So my final conclusion is this: Buy all three types of fins, the jetfin, force fin and scubapro nova and find out for my self. I just need to find some valued treasure on the bottom, and for that my twinjet max are working perfectly still ;) PS Alec, have you ever made a show about drysuites, different typs, history, perormance etc. What gives better boyency control, neoprene vs shellsuite, shellsuite vs crushed neoprene vs those funny kinky rubbersuites poseidon tends to use?.. Love to hear youre take... PS, sorry for the long feedback 😊

[@garytoups3315]

My Scubapro jets with spring straps weigh 6 lb 9 oz (not 10 lb). A very similar fin (but made of a lighter material), the OMS slipstream weighs 5 lb, 6 oz. I use the Scubapro jets with my drysuit because I get that extra pound of weight in my feet. My Seawing Gorillas weigh 4 lb, 15 oz. I've gone back to the jets/slipstreams because they fit me better and they are better for my finning style. I've also had some friends experience breakage of the "booms" of the Seawing at the hinge point. Pretty rare, and Scubapro has been generous about replacing fins and has also re-engineered, but not something I want to risk on a demanding dive.

[@AlecPeirceScuba_SeaHunter]

Right. The breakage problem was only for the first production. Scubapro was good at replacing any that broke. I don't think it's a problem anymore. The only advantage offered by the old, rubber fins, Jets, Rockets, etc., is their weight. If you need extra weight on your feet, as with a dry suit, they might be a good idea. There is no fin kick that cannot be done with Novas. Some fins, the split fins and a couple of others, are difficult to use when trying alternate kick styles, but not the Novas. They are a fully symmetrical fin with a proper bend to suit all kicks. In fact, their design which utilizes the entire upper fin surface as a driving force is better than the old Jets/Rockets. They do take a few dives to sort out as with any new piece of gear. I think some divers put them on, try to kick as they always have and it feels odd so they stop trying. Too bad. Take care. Alec

[@steveaustin9386]

Alec, Have you seen the Sherwood Triton fins? They are styled on the old jet fins but very light and flexible! I had a pair of Cressi frog fins and hated them. I bought the Tritons and found them to be brilliant in every way and they have the vents same as the jet fins! But like you said, everyone's different!

[@AlecPeirceScuba_SeaHunter]

I know the Triton fin well. I sold lots of them. Very nice style and works well too. The Cressi Frogs are good fins but they do require an athletic leg to work them. Alec

[@sheldoncompton6326]

What do you think about freediving fins for scubadiving?

[@KimonFrousios]

Freediving fins are made to propel hydrodynamically shaped bodies at decent speeds. The drag from the scuba gear might make them uncomfortable to use. More certainly though, they'd be awkward and probably destructive in tight spaces (wrecks, tunnels, gullies). Freedivers have the ability to twist their bodies to work with the fins. With scuba you can't really do that. Already I wish my regular fins were shorter for such dives.

[@AlecPeirceScuba_SeaHunter]

I'm sure they would work but what a nuisance on dive boats. There's enough problems now with conventional fins. imagine divers on a dive boat with fins that are 3' long!! Thanks for watching. Alec

[@spencerboaz2385]

Lol watching this took me back to when I was building and designing speaker enclosures . Sometimes you have to explain things so a six year old can understand it to get through to the adults . When you say geometry , algebra , physics and yes you do need to understand them to design enclosures and speakers , you get that deer caught in the headlights look . And some of the new fins are all about marketing , I'm sad to say .

[@moclepocle]

Alec, has commercial pilot, and engineer myself. I guess, from the manufacturer point of view, when they designed the fin originally, specially the very first one you showed, the heavy rubbery one, it was to take advantage of the Bernoulli effect behind the fins. A little complicated to explain here, but read in Wikipedia "Bernoulli Principle" and look at picture in there about the wing of the airplane. Also next time you fly, one of the modern airliners, look at the wing, when the flaps are totally extended, specially the TRIPLE SLOTTED ONES in a humid day. Also you minimized the Eddy Currents at the edge of the fins, in the down stroke. Regards. en.wikipedia.org/wiki/Bernoulli's_principle

[@AlecPeirceScuba_SeaHunter]

Thanks for your very thoughtful comment. I took quite some time to look at it and to review good old Bernoulli and to think about how it applied to fins. Interesting idea but I have my doubts about whether the fin guys in the 60's were that sophisticated. Also, trying to determine how Bernoulli's Principle applies was hard. The increased velocity of any water over the fins would be on the bottom side of the fin during the power stroke. That is, water rushing through the holes would pass over the bottom of the fin - the side that's facing up on the downstroke. It would therefore create drag on that side which would add to the effort required to force the fin down through the water. It's hard to picture without a diagram, but essentially the diver is trying to force the fin down while Bernoulli is trying to lift the fin up - as in an airplane. The faster water flow over the uppermost surface of the fin (wing) tries to lift the fin (wing). Make sense? Alec

[@AlecPeirceScuba_SeaHunter]

Ok Michael. I accept your expertise and insistence that the slots are valuable (can I use the words "may be valuable"?). You have to agree that it's hard to visualize and a difficult idea to accept. Alec

[@justaguy9203]

Do a video on how to buy vintage gear

[@enriquebejar7772]

Hi, Sir Alec! May I ask your take on the “modern” black old rubber fin...... same design but made using modern lighter materials like the APEKS RK3. Love your channel! Thanks!

[@AlecPeirceScuba_SeaHunter]

While the greatest change in fins has been the use of modern materials, there are many really good design improvements too. So the lightweight, strong and flexible materials of today are much better but so are many of the modern features such as quick adjustable straps, modern blade design, proper shape foot pockets, central ribs for water flow and strength, channels to direct the water and so on. The old black rubber fins (Rockets, Jets, etc) were great at the time. That's all we had. Now there are fins that actually fit your foot, are efficient, light, strong, last forever, etc. Divers clinging to the old design really don't have a good reason. I've heard it all - weight, control, etc. A good modern fin gives you all you need and a lot of advantages. As with anything new you will need to use it for awhile and you'll see. Good luck. Alec

[@MrBass-nt5fw]

THANKS , GREAT INFO NEW DIVER

[@AlecPeirceScuba_SeaHunter]

Thanks for watching. Alec

[@georg9967]

Hey Alec, I'm not sure if they were ever marketed in the US but scubapro made a Scubapro NORDIC fin for a very short time. It's a jet fin with no fins. Far superior to the jet version. Never understood why the jets are still such a popular thing, it's just lost propulsion. . . Maybe cause they look cool?

[@AlecPeirceScuba_SeaHunter]

I don't recall the Nordic fins but there were many copies of the Jet/Rocket fin, some with holes and some without. Probably the best although not terribly popular, were the Healthways fins. They were very similar to the Rocket but featured a rubber flap that actually closed off the holes on the power stroke. If you believe that having holes is good because it reduces leg strain on the recovery (up) stroke, then the Healthways fins were perfect since the holes accomplished that, but then on the power stroke, they were a solid face to drive the water. I have a pair hidden away and I'll feature them and the Rocket/Jet theory in a Vintage video. Thanks George. Alec

[@Ex7878]

I have a weird relationship with the Scubapro Nova fins. When I first saw the fins (on your channel of course), I thought the fins were the ugliest and weirdest things ever. Now I think they are interesting. Who knows ? Maybe next year, I will have my own pair of novas 😀

[@AlecPeirceScuba_SeaHunter]

I'll bet you'll like them. I was sceptical as well at first glance but, they work really well especially for my old legs. Alec

[@eddaly7014]

I'm so sad that the Nova fins are so good... I agree, I think they're ugly af haha. I was always set on the jet fins. I know they're good for back finning. That's something I don't hear mentioned. Are the Nova fins good for back finning?? Does anyone even care about back finning?

[@robertbritton656]

I find back finning in the Novas difficult, but then again I never really have a need to do it. I also find they aren't brilliant for drysuit diving. The lack of weight means my feet become positive very easily.

[@Maxyshadow]

What a brilliant video thanks!

[@AlecPeirceScuba_SeaHunter]

Thanks for watching. Alec

[@hedgehog7562]

Hello again Alec. My answer to the question about the louvers in both styles of fins was and is to save weight. The 60's style is really not functional as a performance enhancer. The industrial use comes from the short length of the 60's style. The newer ones are a lot longer. Besides louvers were the fad of the sixties. Does any manufacturer make a short lightweight fin? like the 60's model.

[@AlecPeirceScuba_SeaHunter]

Quite true. I would still recommend the Scubapro Novas. They look longish but are deceiving. The foot pocket is part of the blade and that makes them look long. They are not long. I can't think of any other (good) short fin. Good luck. Alec

[@evenhandedcommentor6102]

There is the Aeris/Oceanic Accel fins. Short and light...lighter than the ScubaPro Nova's. They work surprisingly well.

[@forgot_my_name_again]

I really dont like the very long fins and specially the split fins. These fins blow a lot of dust up in the water resulting in poor visibility and are only suitable for flutter kicks. I really prefer the short hard and havy type fins. Specially when diving in a drysuite. At least for the extra weight and they are smaller. So less chance you'll hit something or someone.

[@BCBOYS92]

Hey Alec, here's one you probably get a ton. What do you think about force fins? I got a pair that I won and I'm still not convinced they're great.. cheers

[@AlecPeirceAtTheRanch]

I used and sold Force Fins for quite a while. I found them interesting and they worked well but personally I didn't think they were a great improvement - maybe over the old Rocket Fins at the time they first came out, but not so much now with good modern fins. And, no disrespect, maybe they can justify it, but the cost of Force Fins today is pretty prohibitive. If you like 'em, go for it but I suggest you try a pair first. Alec

[@volvoman2324]

they are great for body surfing and also nice and easy on your joints you can use them all day.

[@patryka11]

They put holes because the place just near tose is a drag. The fin working only when bend. So old fin without holes would be very difficult to kick. Mind that even newest Seawing Nova has free space similar to holes. Did not test Seawing Nova myself but heard they are great. I highly recommend to buy new, modern fins. I bought Mares Exite fins. They are more traditional shaped but following similar new technology which is bend just after foot giving powerfull kick but no pain on the knuckle. Or Seawing Nova or any other modern fins. Huge difference.

[@AlecPeirceScuba_SeaHunter]

Thanks for your comment. Alec

[@max_zazu]

Al these comments about the holes are so comical. I sat down with the designer of the Seawing Nova at DEMA. The holes have no purpose other than to clip them onto a hook. He was amused by all this "theorisng" from engineers and physicists about purported function. SP product designers requested the hole from customer feedback. Nothing to do with any dynamics. I told him that he should claim credit for the brilliant design instead. Actually Alec is doing that for him!!

[@MrMatzetier]

I agree for wetsuit diving, but if you dive with drysuit i prefer the old jet fin. The weight on your foot helps too trim.

[@AlecPeirceScuba_SeaHunter]

I suppose you have a point. It's that or wear ankle weights, for some divers anyway. Alec

[@OlorinEa]

Hi Alec, your point does make sense. But only under the assumption that the kick used is power kicks and scissor kicks right? I mean I find I have an almost exclusive preference to frog kicking and there the jets are great whereas long pliable fins make you lose a lot of power, no?

[@AlecPeirceScuba_SeaHunter]

Everyone is different but I've had no problem using any kick with the Nova. If you place a Nova on top of a Rocket you'll be surprised to discover they are almost identical in size and shape. Materials and design features are different but not size. Alec

[@OlorinEa]

thanks for answering !

[@UmTurista]

Hey Alec. I really love your clips. Many thanks for this. Can you make a comparison between the Scubapro Seawing Nova and the Hollis F2 fin? I like to by a travel fin but so many people told me that the (they say spoon-fin) Nova is the wrong fin for different fin technics and the Hollis can be a good choise...

[@AlecPeirceScuba_SeaHunter]

Look for vides S09E12 Which Fin To Buy, for a comparison of the Sea Nova and Jet Fin. Fins are a very personal choice for fit and power. Best to visit your local dive shop and try both on for fit/feel. Ask if they have a pool night where you could try both out so you're comfortable with the fins. Everyone has an opinion but its your money and fun so your view matters the most. Alec

[@francisho3056]

I spend many hours on the swimming pool and I have a pair of swim paddle for my own training session, came to my notice the other friend of mine having a swim paddle without any holes and he is complaining those are no good paddle, it is very hard to control and I dont have problem with mine. the difference are on just holes.. I asked him to get a driller and drill couple of the holes on the paddle see how it perform. Instantly the paddle feel much controllability, feels balance & doesnt wiggle from side to side as before. Now why those Scubapro has holes on their fins, it is as simple as provide balance during the underwater swimming allowing the water guide the fins to move as horizontal as possible thru these holes.

[@AlecPeirceScuba_SeaHunter]

I'm not sure if that was the idea when the fins were first developed. They were marketed as having more thrust with less effort. But it's interesting to hear about your experiment and how it improved the paddle. Alec

[@danielso6589]

Hi, i love your videos as they help me out a lot even though im not a beginner anymore, however im now interested in cave diving and was wondering if the scubapro seawing nova will be any good as cave divers prefer a stiffer fin. Thanks for your time

[@AlecPeirceScuba_SeaHunter]

I did some cave diving before it was cave diving. Now cave diving is a highly organized and well supervised activity. I've used the Nova in many different environments (not cave diving) and can't see why they wouldn't work well. Many cave divers are convinced that the old, heavy rocket-style fin is the only one to use for cave diving. Having closed their minds to that discussion it would be hard to change it but any intelligent diver would always be willing to try new stuff and find out for himself what's best for him. Personally I think they'd work well and they have many advantages. You'll have to try it Daniel. Thanks for watching. Alec

[@adamelmahdali9049]

Hey Alec . what do you think about closed pocket fins , are they less efficient in the water and what are the con of such fin ? Because dive in northern morocco it doesn’t get very cold so there is no need for boots and honestly there not my favorite thing to wear .

[@yurig7482]

Hi Alec, I love your videos! I'd like to ask you what's your take on split fins and what fins would you recommend for technical diving? Thaks a lot, I'm learning a lot from you! Take care!

[@AlecPeirceScuba_SeaHunter]

Tech divers I've spoken to do not like the splits. The claim is that they cannot back fin with them. I don't have personal experience in that. Tech divers seem to favor standard design, stiff, heavy fins but that could be a mistaken impression on my part. There are lots of tekkie sites available for your to pursue that question. I personally have used several of the split fins and they were OK. Since then (they've been around over 19 years!) fin technology has improved even more and there are other styles I find much better for several reasons. Just my opinion but I suspect you'll be hard pressed to find split fins in a dive store on a few years. Thanks for watching. Alec

[@KevinSmith-hc4pc]

Hi Yuri. Alec actually did a video on split fins as episode #8 in this series. Look for it six Tuesdays from now. Should answer your questions on their pros and cons.

[@yurig7482]

Kevin Smith awesome! Thanks a lot!

[@dime275]

Yuri Gavriliouk hi. I'm a new diver and have the Scubapro twin jet fins(split fins). I hate them. They are too floppy for current. Also can't frog kick etc... Don't get them. Stick with paddle fin style

[@yurig7482]

dime275 yeah, split fins look cool but none of my dive buddies ever tried them so I didn't know what to think of them. Thanks for sharing!

[@punkrose1310]

I have both jets and novas and use them with different gear. I prefer the novas when in a wetsuit and the jets with my drysuit. One of my instructors refers to jets as 'proper fins' because she dives caves and uses them frequently. That's not the case. Any fin is a proper fin. My novas, for example, can power me through the water very efficiently when I need it but aren't so great for frog kicks. My jets are great for frog kicking but are much too heavy when in a wetsuit. It's all personal preference.

[@AlecPeirceScuba_SeaHunter]

Right on Punk. What's best for you is not necessarily best for me. I hate it when someone says, "If you're not using a XLDT Matrix BCD, you're not a good diver". That's a dumb as me saying that if you're not driving an F150 you're not a good driver. An unfortunate driver maybe but not bad! Take care. Alec

[@MickFriis]

Hey Alec, Thanks for another awesome video, im a big fan and i have learned a lot from following your channel .. This particular video you actually questioned something that i would be able to respond to, so here we go. You said that you have never heard a reasonable explanation to why the manufacturers put holes in the fins, but if you take a look at how fins actually work within the water you will see that the tip of the fin actually spills a lot of water while the start of the fin (just next to the foot) actually creates a lot of drag. It is only the middle section of the fin that is around 45 degrees angle in the water that actually generates any thrust, so manufacturers discovered this and decided to cut holes out the part of the fins that actually dont generate any thrust anyways ... If you watch this video where scubapro crew explains the science behind the Seawing he also explains in greater detail why there should be holes in the first section of the fin. (around 21 min. in) kzbin.info/www/bejne/eYHMnp-CaaeNg5I Once again thank you so much for all your videos , looking forward to the next one :)

[@AlecPeirceScuba_SeaHunter]

I watched it twice. Really neat Mick. It answers a lot of questions and also reconfirms my statement that Scubapro is serious about making good products for divers - not just banging out cheap, look-alike stuff. Thanks. Alec

[@LadyLara1338]

Tried the Seawing Nova once. Worst fins I ever tried. Terrible for the energy saving frog kick. My favorites are the OMS Slipstreams, same shape as the "old" Scubapro, but modern light weight material.

[@AlecPeirceScuba_SeaHunter]

I'm guessing that's why there are so many different styles of fins available - one to suit everybody. Thanks for watching. Alec

[@NguyenBaHien16]

Very useful video. Thank you, Sir!

[@AlecPeirceScuba_SeaHunter]

Thanks for watching. Alec

[@Hockeyfan9884]

Ok, listened to this episode and bottom line question is , which company to buy the white fins from and the average cost of them. Thank you.

[@AlecPeirceScuba_SeaHunter]

The white fins are Scubapro Nova Wing fins. They are not cheap but I suspect you could get a pair for under $200. I've seen them on eBay, new for about $150 or even less. Alec

[@djsalose]

the holes are there to let water trough, so close to the foot the water resistance is greater than the force produced..

[@trainwrekk9685]

Something you dont seem to keep in mind is divers using a dry suit. Heavy fins is good for the correct position in the water with dry suit boyancy in mind. Jet fins all the way.

[@AlecPeirceScuba_SeaHunter]

For light feet you could use heavy fins or ankle weights which are adjustable, fin's are not. If jet fins work for your setup and dive profiles, fantastic, enjoy it. But as someone who sold gear from kids to grandparents, not everyone has the foot/leg strength to work heavy fins. It is very rare in diving to find one item that everyone uses, be it rec or tech divers. If you happy and you know it clap your fins! Thanks for the feedback. Alec

[@rmsmith2396]

TrainWrekk I like jetfins too, and dive them in cold water (in a wetsuit) but my drysuit boots don't fit in those small jet pockets. What do you use?

[@Mrich775]

I am curious about your take on the jet fins specifically in the context of frog kicking and tech diving with drag laden drysuits and gear, or if you know of a modern fin good for that. I agree my jet fins are silly for rec diving and flutter kicking(Novas for that), but I have yet to find a better fin than the old school for that specific type of dive and kick. Just curious since you glossed over the techies.

[@Yggdrasil42]

I really liked the Apeks RK3 that I borrowed for tech diving last week. The RK3 is slightly positive and the RK3 HD is a bit stiffer and slightly negative. Easy for frog kicks, back kicks, etc.

[@Mrich775]

I tried the apeks, never really fit my dry or wet boots well, I stick with 2 pairs of hogs now, 1 for wet, 1 for dry. I have my opinions, was really just looking for his, ive been all set for long time haha.

[@chelseylate649]

Hey Mr Alec. I have a size 15 us foot and would like to wear a protective boot maybe 5m, I'm from Indiana and will do more lake dives. Have not found any fins that big. The xxl only goes to a 13 and from what I learned from you I dont want my heal hanging out or not fitting with a boot. What would you recommend sir? Not a fan of heavy duck feet but might be my only options. Thanks.

[@AlecPeirceScuba_SeaHunter]

Size 15! You don't need fins!! Just kidding Chelsey. It's a problem I've faced with lots of divers. My son is size 14. In your case I suspect that the size 15 is to accommodate the length of your foot. It is probably a fairly standard width. So you need to find a pair of fins that will allow you to slip your foot in without being pinched on the side. Probably your foot will extend too far out the back of the foot pocket but if you have a good boot, thin but still warm and with a stiff sole, it may be fine. Try a few fins in the pool. You don't need dive gear. Just fit the fin and boot as best you can and then swim a few lengths finning as hard as possible. If you get a cramp or pain in the sole of your foot, try another pair. If not, that fin will do the job. Of course it's ideal if the foot is supported over most of its length but it's not absolutely necessary. Fin slowly and smoothly and you should be fine. And note that one fin manufacturer's X-Large is different from another. Check out Cressi fins and Mares too. Good luck. Alec

[@CUCABURRAAustralia]

Hey Chelsey, just a small hint, if you don't mind. Try the TUSA Solla XL size, they have quite a big and wide foot pocket. All the best.
