How to Choose a Dive Computer - Choosing the wrong one can be an expensive mistake.

[@bloodymarvelous4790]

Air Integration is not used to calculate nitrogen saturation. It only keeps track of your air pressure, calculate dive time remaining, and will warn you when you hit a certain threshold. The computer may know how fast the breathing gas is consumed in pressure, but it doesn't know the volume of breathing gas consumed because it doesn't know the size of your cylinder(s). It may register you're using 5 bar/min, which on a 200 bar cylinder means you'll have 40 minutes of dive time. However, whether you're diving a single 12 liter cylinder or two 10 liter cylinders makes a huge difference to the volume of gas you're consuming and the amount of nitrogen that is absorbed in your tissues.

[@coralkeyscuba]

I agree with the calculation of nitrogen saturation. No piece of dive gear measures that. It is simply an educated calculation from decades of data dealing with the Navy dive tables. Our limits have been adjusted as people developed decompression sickness over the years and have become more conservative as a result. However, practically speaking, no matter the size of your tank. 63, 80, 100 cu ft. You have a starting pressure, and the dive computer measures it as it decreases. It also doesn't know the size of your lungs verses the other divers. But every diver that uses an air integrated dive computer has much more information available to them than the non air integrated diver computer offers. When you use one you get used to the time it takes to drain your tank therefore you get used to your "normal" dive time. You have more info to use in your own personal calculations to determine your safety threshold. If I covered every possible scenario it would probably be a 12 hour video. I am confident in saying an air integrated dive computer is safer to dive with and has many advantages than an non air integrated dive computer. Thanks for watching. More to come soon. Freddy

[@nbazazo]

Great info. I am convinced about buying an air integrated dive computer but here is the question: While diving overseas and renting equipment, are dive centers willing to add the AI transmitters? Or what would be the least complicated way to integrate on rental equipment? TIA.

[@LeviathanScuba]

Great question. Yes they are. But if you find one that isn't. In your save a dive kit, include a 5/32 alen wrench. That is the size of the high pressure plug in your regulator. Or you will have to take off the high pressure hose. Either way it is simple and easy. Screw your transmitter in only hand tight. Done.

[@jelespuru]

My biggest areas when considering a computer, how to change battery or charge, having Bluetooth to get the data and air integration. I also like the options for air and nitrox but most computers already have a his feature.

[@coralkeyscuba]

Changing a battery is important. You used to have to take it to a dive shop for them to do it. Now many have user changeable batteries. Just pay attention to the o ring when you seal it. One grain of sand can let water in. Now we have choices with built in rechargeable batteries. They will need to be factory changed but very affordable and easy to have done. Usually they last about 8 years. Thanks for watching. More to come soon. Freddy

[@scubajuan]

Yes, and kinda of. You should plan a dive and know how deep and how long you can stay at that depth. In the abscess of a computer, weather you have it, or not, or it breaks, or is not setup correctly, you should know how deep you are diving and for how long. FYI I use two computers on every dive, one with AI and I still really on my SPG and try to plan my dives.

[@LeviathanScuba]

Nothing wrong with being cautious. I have found my worst case possible scenario is that I abort a dive. I can do that to save myself all the redundancy. I say that and I mean for purely recreational diving. Thanks for watching. More to some soon. Freddy

[@LeviathanScuba]

They are a game changer. I probably dove for about 12-13 years prior to them inventing a dive computer. So I was used to it.

[@TheSmileyTek]

I ordered the Suunto Vyper Novo and transmitter because it was the cheaper AI I could find. I put most my budget into the MK25 EVO / A700 Black Carbon. I think I made an OK choice....

[@LeviathanScuba]

Might sound a bit rough but at some point when your frustration level reaches a high level you can sell your suunto and get a much more user friendly dive computer. The one thing I am is brutally honest with dive gear for people. The Suunto brand as a whole is very high quality. Made well but you need to be an engineer to use them. Joke but almost true. They are not user friendly at all. Now if your IQ is above 150 then you will have no problem at all. Mine is not. Your other choices are great. Thanks for watching. More to come soon. Freddy

[@TheSmileyTek]

@@LeviathanScuba You weren't kidding about frustrations. Tested pressure transmission on the way to the dive spot and it worked. Get to the dive spot, and I was unable to get the Vyper to sync back up. Aside from that, Air mode just disappeared from dive options. Only had Off, Nitrox, Guage, and Free as options. What a piece! Luckily I purchased a mechanical SPG as a backup, and I was still able to dive. I should've just spent the extra $ and purchased a Shearwater Teric or something. As a matter of fact, I'm going to get this thing working properly and give it to my son for now. I'll just suck it up, and spend the money on a Teric. Lesson learned.

[@Alex-ev3gd]

I completely agree that maybe after the regulators the dc is likely to be your most important equipment! But especially on youtube I hear the dendency to advertise them as super safe and super easy ((in a fading voice:) they tell you all what to do ... no training nessecary). Sadly I personally can't get comletely along with that. Two stories below which might be considered. The highest class dive-computer I know has as first sentence in his manual:" This computer will fail! It's not a question IF but WHEN." I already had a predecessor Computer which did fail on a nightdive around 20 meter (60ft ?). Now your playing duck ... I can't really see the tendency to remove the Presuregauge (with integrated depth-meter) as good way to go. For myself it's positioned to be a bit more uncompfortable to read and a bit more streamlined, but I wouldn't want to miss it at all. PLEASE DON'T SELL DC's AS SO EASY TO USE! If you don't learn the manual and have no understanding of what's happening the DC won't help you! A very wise man once told me:" As experenced diver you will now whats written on the computer, then you look at it and check to be sure. I already had two buddies with which whom we zeroed the NDL. Both somehow where completely confused what their computer is suddenly doing, and didn't understand that they had a ceiling obligation. Both where even more confused when the deepstop/dekostop suddenly vannished, even we didn't do a specific stop, but a slow ascent.

[@coralkeyscuba]

I agree with your statement to sell them as so easy to use but they are! Doesn't mean they won't fail though. It is totally up to the diver to be safe, not the computer. The truth of the matter is that a very high percentage of people have no idea how to really use theirs. What is the alternative? They don't remember how to use their tables for multiple dives, nitrox, either. So, do I wish everyone would study the owners manual and really understand their gear? You bet, but I also wish my coffee in the morning was free. I have many people on trips ask me how to work their dive computer. Wrong time to be asking how it works. A little comfort should come that if your computer fails, you don't die. Worst case scenario is that you surface. Battery dies but you don't. Remember it wasn't that long ago that the DC was invented. I learned to dive prior. I used my watch. I personally trust my life to my dive computer. I have enjoyed thousands of trouble-free dives. I expect I will enjoy thousands more. No need for a pressure gauge for me. If my dive computer fails, I can end my dive. I also have much experience with low pressure in the tank. I can recognize a low tank long before it is empty. Plenty of time to make it to the surface. So if a novice diver can look at their wrist and notice a graph that is Green, Yellow, or Red to signify their current status? I think that is good for them. I hope they learn the other functions but if that is all they decide they want to use, then better than nothing. Thanks for watching Alex, and taking it to a higher level. Freddy

[@Alex-ev3gd]

@@coralkeyscuba That was exacly my point! :) You say you have the experience (of low pressure tank) and I asume you refere to some quite simple shallow dives, where 10bar will get you to surface and have you take your safetystop ^^. No need for back-up. back at 20m, night-dive, close to zero NDL at an underwater cliff (? if thats the english-term) ... I sure loved my gauge and dephtmeter when dc went dark, and the knowlege that I shouldn't skip my safety stop at this point. Maybe a minute or three at 7m wouldn't be too bad neither. I see most unexperienced divers tent to reach/test their limits (now where they're out of sight of their teacher) and I can completely understand this. For me this is part of every (more or less) extreme-sport. And that's where the advertisement kicks in, and what I would whish for: Divecomputers are crucal equipment! But still you need to now what's going to happen. You get (all) information, BUT you still need to work with that. Second time where my buddy was confused about his dc, we were on the second dive. He still had about 150bar in a 15l bottle. Would have been quite easy to reach serious deco-steps. Even IF suddenly realising the necessary stops the rest-air might get quite ... interesting at that point. Bottom line: Divecomputers are great! Still get your s***t together and learn stuff! Read the manual (at least look at the pictures)! Some dive-plans might be much better with backup-gear. And in my opinion, this should be the advertisement. By the way: Still great video and a really well made channel, you got! Hopefully you will get more viewers!

[@LaT00pe]

In the Red Sea (Hurghada, Marsa Alam), they don't provide dive computers, even to rent, but let you dive without. I think we should call them out on it collectively to better respect security features. The fact that there's so many accident there is no surprise to me after what I saw...

Henry's law is one of the gas laws formulated by William Henry in 1803. It states: "At a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid.AND NOT DEPENDING ON BREATHING RATE ...sorry

[@LeviathanScuba]

100% agree. Your blood, (the liquid) is not saturated with nitrogen. Therefore, more can be added. Your breathing rate increases nitrogen bubbles in your blood at depth. The longer you are there the more you have. ie, too long = the bends if you rapidly ascend. Or you decompress to allow off gasing slowly. Thanks for watching. More to come soon.

[@ΓεώργιοςΜπρίνταλος]

What is the "Time Remaining" ? If by "Time Remaining" you mean the NDL time , then I tell you that it doesn't change between Ai and not Ai computers. Some new algorithms use some more parameters like skin temperature and heart rate to adjust for a specific individual, but I never hear for an Ai computer that adjust the algorithm according to the diver's sac rate... Also if that worked it would have many flaws, for example in the case of free-float it will decrease the NDL rapidly assuming that the diver breathed that air!

[@coralkeyscuba]

I referenced both types. I believe you are referring to my example where two divers using non vs AI computers. One sucks down their air quickly and the other can last quite a bit longer. The Dive Time Remaining on an non Ai computer would look the same. Whereas a computer with Ai would calculate differently for both divers because of their consumption. Sorry if I confused anyone. I will go back and watch that to see if I need to change it. Freddy.

[@ΓεώργιοςΜπρίνταλος]

@@coralkeyscuba the non AI doesn't display a "Remaining Time" because it can't calculate the sac rate of the diver... Non Ai computers give only the NDL time, but the Ai versions will not change the NDL according to the sac rate.... I think it can not be proved that a diver who breaths more will store more nitrogen in his tissues but if his heart rate goes up at the same time, then is another story!

[@rubiksfaq9214]

​@@ΓεώργιοςΜπρίνταλος I agree with you on this; the No Decompression Limit (or No Stop Time) does not change based on Surface Air Consumption or remaining air but rather the level of conservativeness which can be set on the computer itself (Scubapro A2 has a "Micro-Bubble" MB level which can be adjusted by the user) and the algorithm used by the dive computer itself to calculate your N2 saturation levels, resulting in the final NDL available for diver during and between/after dives. The NDL could be affected by HR/temp, etc. however that is a separate issue from AI vs Non-AI and requires another sensor like a HR band to be used by certain dive computers

[@newera3757]

AIR Integrated was the BIGGEST waste of money. I recommend a basic computer for depth and your tables, and monitor air separately - again with a basic needle gauge. Tech fails over and over. Unless you are a dive master - you don't need all that fancy junk.

[@maxheadrom3088]

What would be the best cost benefit for an air integrated computer? Thanks!

[@LeviathanScuba]

Your life! Meaning the best benefit period of air integration over non is safety. A few other benefits are longer dive times (because it knows your current profile in real time. doesn't have to round up like we learned in dive tables), more information about your dive. If they were free, everyone would take air integration. I personally the regulator and dive computer are the items that control your safety the most. I want the safest dive computer money can buy. Being in Brazil, you may have to search online. Check out the new Tern TX by Shearwater. About $400 less than the Teric and has all the features but not the technical diving stuff, like mixed gasses, closed circuit, etc. Thanks Max. Have fun, go slow, get the right gear.

[@PedroOjeda]

I have been unable to confirm that any AI integrated computer adjusts the algorithm based on my breathing (for example I read the manual of the Perdix 2 and it does not mention it) which ones do this?

[@LeviathanScuba]

Pedro, the algorithm does not adjust. It remains constant. The reason Air integration adjusts based on your breathing is simply because the computer calculates the amount you are consuming. If you are breathing light, verses breathing heavy the computer uses that information to adjust no decompression limits, dive time remaining etc. My point was that a non air integrated computer has no idea what you are consuming. Therefore no matter your time or depth it is always an assumption based on Navy dive tables which all algorithms are based on to some measure. If you stretch a tank for a long time and I suck one down quickly the non air integrated computer will say the same if we are together diving the same profile. Yet my tank will be empty much sooner than you will. Therefore dive time remaining cannot be the same for both of us. Hope that helps. Thanks for watching. More to come soon. Freddy

Yeah I guess all of who started our dive career with just gauges are lucky to be alive. Or was it we were trained to use the dive tables. Yeah and who wants to do more thinking when you dive cause a diver who thinks is a bad thing. Yeah and looking at your gauge for your tank pressure is so hard. How did we ever do that before computers. Seriously how much harder is it to look at your gauge versus looking at your computer. A good diver believes in redundancy even if he has an integrated air computer he/she will keep her gauge. I became a divemaster in 1981 and am now a master scuba diver and until this year never owned a dive computer. I used tables on over 1000 dives and have never been bent not ran out of air. We are dumbing down divers with electronics and that is sad. We planned our dives and dove our plans, it was simple.

I am a Suunto dealer and they are very high quality. My guess is that you are an engineer either that or your IQ is very very high. I say that because one thing they are not is easy. Maybe for you but not for the average person. I mean their most basic models are yes but any computer they make that is their upper line is not very user friendly. I had a rep in my shop that I asked a fairly simple question about the D5 and it took him 20 minutes to figure it out. When the average diver out there barely knows how to use their own dive computer it is a major feature to keep them as simple as possible.

[@huntermetrejean232]

Great video! I do have a question though. You said that if your non ai computer tells you it’s time to go up, and you had air more air left, that really you had more time. But isn’t your computer supposed to tell you when to come up due to the nitrogen levels in the blood getting close to the limit? So even if you had hour of air for example, but the computer says that you need to go up because your nitrogen levels are up, wouldn’t that trump your air being high enough to stay?

[@MsLeessy]

As he said, the nitrogen levels in your blood depend on how much air you consumed. The computer doesn't know how much you consumed though, so it is an approximation.

I know you can't crystal ball that, but just wondering what average divers equipment turnover time is. Thx!

[@coralkeyscuba]

Dana when you say nice that usually translates to quality. We still service quality dive computers that were purchased 20 years ago! My advice is go slow and get the right stuff and it will last you a long time. The science behind how a dive computer works hasn't changed since the very first ones. The technology doesn't really change that often. Yes, there might be a few features that change like adding a flashlight to a dive computer but if that wasn't on yours then it doesn't require a new computer. I would choose quality, great visibility, and a name brand. Preferably brand new or extremely new used model. Not years old. If you haven't seen the review of the Shearwater products, take a look at those. Avoid the Garmin at this time (Review is coming soon with a deal breaker that makes this computer a bad choice currently). Thanks for watching. Freddy

@@coralkeyscuba "The technology doesn't really change that often.". No, the technology changes rapidly, especially the dive computers and torche lights.

Now they are smaller, safer, and remain longer. If you buy a quality product, it can stay with you for many years.

I have a Scubapro D300 regulator I bought 37 years ago, it works great. Just need to service it regularly. My last computer is about 8 years old, it also works great. I am looking for a new computer that it is easier to change batteries, Bluetooth to get the data to my iPhone and air integration.

[@asmith5488]

so do you not check your buddys psi or air left anymore? we were taught to know your buddys air at ALL times... have things changed in the past 30~40 years? do they not teach PO2 and SAC in AOW? because we all know NDL does not exist in less than 30ft and is also not an issue at 60ft on old tables now new tables show 50xmin max on Air... considering a diver who does 110 ft dive for 8 min on 3000 psi and comes to the surface w 1500 psi in the tank.. where does the computer integrated and non integrated makes a difference? reason I preface this is there is no measure to determine fatty tissue saturation at this moment in recreational diving.. just let me know if I have missed something since 1984 lest we do a Arterial Blood Gas measure before returning to surface ( which at the moment is not a viable recreational option ) or measure the exhaled PPm of gas out vs gas in to calculate the %%PP consumed. again not a viable function... the use of a PO2 or partial pressure tank measurement also adds a free flow reg issue to consumption... ( case in point if you are too lazy to use tables AND are diving Depth or do not plan your dive and dive your plan ) how do you handle a unknown free flow on a 2nd ( octo ) which happens at depth with integrated computer if not caught for 300 seconds or there about "this occurring during the dive for almost 300 seconds?" @ 90~100 ft 30~33M knowing the tables one can determine this and evacuate or fix/continue the dive.. With a non-integrated computer there will not be a AI ( Automatic idiot ) screwball calculation blowing the dive plan. In the above scenario the integrated system will have you doing a 20min deco between 10~20ft am I wrong or am i correct? I have seen this with the scubapro(noob) Galileo SOL uwaturd integrated dive computer ( which nearly killed a diver as he was worried and @ 300psi @ 30 ft ) we ended up running tables to ensure the person they were safe vs sitting @ 30ft for 40 minutes due to an IO software flub.. due to [you guessed it ] a freeflow on a secondary at depth for a timeframe for estimated 300 seconds.. for a limited time until it was caught by the divebuddy and FIXED max estimation was about 5 min at 90 foot and we calculated it blew about 750psi out of a 80cf tank single. Integrated vs Non integrated comes down to ( do you know your sac or do you not know your sac ) and ( did you dive stressed or unstressed ) "recommend watching dave is not coming back" Also look at reefnet.ca dive logging

[@cwilliams6884]

just buy a shearwater and be done with it

[@LeviathanScuba]

They surely are fantastic computers. We are doing a review of the Tern TX coming out in February. So far it looks great. Taking it to Fiji this week. Thanks for watching. Freddy

[@cwilliams6884]

@@LeviathanScuba can't wait to watch that review, i'm definitely interested in seeing what the tern tx can do!

[@LeviathanScuba]

@@cwilliams6884 Just playing with it prior to the trip. This will be an easy review. It is basically the Teric without some of the Technical diving stuff. So, no Closed circuit, no Helium or tri gases. From what I can tell right now it is the computer people have been asking for when they don't dive technical. I get people that say "I don't dive that way and don't want to pay extra for all the stuff I won't use." Well, Shearwaters answer seems to be the Tern TX. It retails for about $400 less than a Teric. So good on Shearwater for coming to the table with a truly recreational, air integrated dive computer. Thanks for watching. Freddy

[@cavemansee7110]

Hmmm g’day I am new to scuba diving normally I only dive when I travel overseas and rent my gear now I’m buying all my stuff which computer can you recommend the Garmin Decent 2 or the shearwater Teric both with Air integration flying from spot to spot and then home after diving may be a problem even though I am only open water

[@coralkeyscuba]

Hello. I'm glad you enjoyed the video. Between these 2 computers, I would definitely suggest the Shearwater Teric. You can't find a better computer on the market right now in my opinion. Garmen makes an amazing land computer. Their dive computer, however, has one feature that I just couldn't get over. It picks up sonar, and an alarm goes off about every 10 seconds. Even when you turn it all the way down, you can still hear it. It wasn't just me that could hear it, all the other divers around me could hear it as well. So, it did get pretty annoying. I really believe that Shearwater makes the best computers on the market right now. Hope this helps.

[@twoknife]

I had the same situation and went Teric. The Garmin is neat in that you get a fully featured sports watch as well as a dive computer. Though I would be more concerned about breaking the dive computer during other activities. It is very expensive as well plus the sonar issue. I just use the Teric for diving and an Apple Watch for everything else. That works out to roughly the same price. The dive log on the Garmin is nicer than the Shearwater though.

[@cavemansee7110]

Ok great advice thanks the Teric it is cheers to all that responded

[@amadeuss3341]

Buying a non-AI computer is pretty much a waste of money in 2022. All people I know with non AI computer ended up getting rid of it within first 20 dives and got a AI computer.

[@ElAmazingGaston]

awesome ! i am just learning and it was awesome :D take care of that throat ! use a glass of water instead of coffing. cheers from argentina :D

[@markfrantz4612]

To shearwater… or not to shearwater…

[@coralkeyscuba]

At this time, definately Shearwater. Thanks for watching. Much more on its way. Freddy

[@haempelmaen61]

Whether or not you have Air integration has no effect on your NDL and your SAC rate has no effect either. Even if you hold your breath for minutes you will still saturate your tissues.

[@LeviathanScuba]

True. Air integration will give you a realistic example of your true breathing, dive time remaining, saturation, etc. Won't help you really change your breathing but practice will do that. Thanks for watching. More to come soon. Freddy

[@Litehamer]

I’m struggling to understand why you’re mixing No Decompression Limits , with gas consumption. Many if not most tech divers don’t use AI and they complete very deep , long and penetrate wrecks etc. Thank you for the videos but I think it’s not ideal to tell divers thinking less is a better way to dive .

[@coralkeyscuba]

Not mixing them. My videos are directed to the bulk of the planets divers. This is not the tech community. I trust that tech divers understand their equipment more so than most of the recreational dive community. And it is a frustration to me that most divers don't understand their gear and skills more than they do. My comment wasn't meant to instruct them to think less obviously. But rare are the dive tables used today. And I do trust modern dive computers with my life, often. Nice to relax and have a nice piece of equipment that helps me calculate my dives safely. I do thank you for your comment, nice to have a diver paying attention. Thanks for watching. Take care. Freddy

[@AndrewR74]

Easy. Start with shearwater. That’s it

[@LeviathanScuba]

I love their products. Very user friendly and great customer service. Thanks for watching. Freddy

[@Boopadoop]

This video should’ve been 15 seconds: want a watch style? - teric. Anything else? - Perdix

[@LeviathanScuba]

Ha, if it were only that easy. Not sure people would trust that. But I agree, two of the very best out there. Freddy

Air integrated on high pressure only good if there is no air bleed.. then it will lock out or screw up the calculation.

[@LeviathanScuba]

Air integration transmitters use exact same threads and o rings as do the high pressure gauges and attachments. So being as they are only about 3 inches long and a lot lighter it actually works pretty well. Thanks for watching. More to come soon. Freddy

[@asmith5488]

40 years and I am finally looking at a computer reason being ... deco a computer as two plus gasses are now in the mix... thus why I am here thousands of dives in on tables ... now trusting a piece of sillycon kind of scares me.

[@LeviathanScuba]

I am with you. However, I have found computers over the last 40 years have proven extremely safe, consistently effective and easy. They continue to improve, and millions and millions of dives have taken place with dive computers without incident caused by the computer. I teach that if the computer has a problem, you aren't dead. Simply abort the dive. Battery dies then finish on your watch or abort the dive. Even these days most computers warn you with enough juice to dive 3 more dives so if you don't change the batter, it is your fault. Thanks for watching. More to come soon. Freddy

when they get a air integration on the 2nd stage THEN i will consider the AI
