Hi Fred, thanks for the complement. It's not necessarily for everyone, but there's a lot of ah ha moments even in a foundational level class. One of my current students came to me for a recreational clinic. When he took it, he always maintained he wouldn't progress to tech (too risky). Then every now and then he'd come back taking another class, then another in between experience dives. That was 7 years ago, he's now a Technical diver and is taking his Cave soon. Have you tried taking one similar? In ISE that would be a BoE.

Ship it all to some kind of reputable place, I've got a scooter with a battery pack capacity that exceeds air travel allowance. On dive trips abroad where I really would like to have it (wreck, cave etc) I ship it a few weeks prior to my chosen dive operator at said destination.

[@meridacavediver]

I’ve never seen a leash leg before, dumb question, what is it?

[@Guykipchoguy]

Hi all, quick question for a beginner, what is the advantage of all of this tek gear vs a CCR which will enable you to always get the appropriate level of O2 based on your deep ? Plus all other advantages of CCR ( no bubbles, warm gas, dive duration, recycle of expensive Helium etc) Thanks !

[@BillyElliot1998]

It’s cheaper and simpler, I guess. And with ccr you also always carry open circuit as bailout, therefore you would also need these stages as bailout, even though you would not use them if everything works out. But you would need to carry them just in case still.. So ccr is way more complex and with more equipment, not less.

[@morillsaberiya]

Hi thank you for sharing. One question is how you keep balance when you connect three tanks in one side of your body? Why you dont flip?

[@LarsDennert]

Aluminum tanks are pretty neutral which is why they are used for stages. Steel would be a problem.

[@eightfifty2309]

Theres levels to scuba im sure but damn after seeing him demonstrating the gas switches, I had no idea that the levels in scuba is that high! 👍

[@billy2141]

It's just practice and can be achieved by anyone if you put the time in. Get your buoyancy and trim spot on first, practice at 6m, 3m and 1m until you don't even have to think about it. Then practice your skills hovering, in trim again and again until you can't get it wrong. Practice at the end of every dive on your 6m safety stop. Plan dives dedicated to skill practice. Practice clipping bolt snaps to your harness at home, build the muscle memory. That's all it takes.

Why do you switch to back gas during deco procedure?..... You have to breath deco gas and go to next deco gas (higher O2) without going back to back gas or bottom gas....... Is it right please advice?

[@KB-gd6fc]

Is the procedure the same if you had two AL80 cylinders and one AL40?

[@pinnacledivingco]

I realize this was a video from years ago, but may I ask, why not simply stay on the 50% till you reached 6m and switch directly to 100% from there? That’s what we train to do as staying on the 50% speeds up deco. Do you have a reason for switching back to air at 9m and spending time off deco gas in between stops until you get to 6m to get onto 100%? Thanks in advance.

[@harrodharrod5239]

My guess is, that it's a safety precaution to avoid the possibility of ascending above 6 meters during all the tank and hose management. I realize something like that should not happen to divers of this caliber, but you can never be too safe.

[@pinnacledivingco]

@@harrodharrod5239 Wait, that still doesn’t make sense. Even if you ascend to the surface while breathing on the 50%, it is still far better than being on air. Additionally, it is a much simpler process (and safer too, as far as deco is concerned) to simply remain on the 50%, and switch directly to O2 at 6m, without messing with tanks. It just seems to me that this video is showing a needlessly over-complication of what should be a simpler process, simply for the sake of “looks” in “demonstration” of a “technical process”. It’s like the idea of coming up with extra steps to accomplish the same thing when you show it off to others just to give it the appearance of being more complicated than it actually is for impressions sake.

[@harrodharrod5239]

If you are at the level of using pure oxygen for your decompression, uncontrolled ascent to the surface at the beginning of your 6m stop means you probably are getting bent regardless of what you are breathing at that moment. My idea is, that if you do the preparation/switch to air at 9m, you have more time to catch up to the possible ascent and never actually break your deco profile. Having watched it again, I'm not even sure, how you'd switch directly from 50% to O2 anyway. I've only had my first dive with using stage yesterday, so even a simple swap to 50% was difficult enough for me. Deploying the O2 while breathing 50% seems like it would be very bothersome though. You'd have to somehow navigate 2 cylinders in the "prepared" position at the same time, which seems too much to handle for me at this point of my diving career. By switching to air while you shuffle the stages around, the whole procedure becomes much more manageable in my opinion. Doing it like that at the end of your 9m stop instead of the beginning of your 6m stop would only add the time it takes to get from 9 to 6m (so 1 minute?) on air while providing 3 meter cushion in the up direction in case you mess up your buoyancy.

[@pinnacledivingco]

@@harrodharrod5239 Simple solution to your conundrum. A: screw backmounted doubles for any form of tec and transition straight to sidemount from here on. Instantly solves your issue of “too many cylinders on one side”. Or B: “right rich/left lean”. Place the 50% on the left and the 100% on the right. Again, done. Once you switch from air to 50%, you stay on it until you get to 6m, then switch directly to 100%. Switching back to air ruins the whole point of accelerated decompression.

[@harrodharrod5239]

@@pinnacledivingco That is not simple solution. That is either getting an entirely new card, getting a new bit of kit and learning how to dive again (in case of sidemount - I know I'm exaggerating with the learning to dive again, but I hope you get my point) or changing your setup from what you might have been trained for (depending on your agency) and learning new drills in case of the option B. Do you have any basis for the claim that "switching back to air ruins the point of accelerated deco"? My understanding of how deco works is, that you need to get rid of the extra gasses dissolved in your tissues. Breathing oxygen rich mixtures accelerates that, as more gasses can escape your tissues thanks to osmosis effect. I just don't see how switching back to air for a while ruins the fact, that during the previous x minutes you have been breathing oxygen rich mixture, which allowed more gasses dissolved in your tissues escape your body without doing any harm. If you swap your computer to the proper gas or account for the fact you are going to be breathing air during the ascent from 9 to 6m in your dive plan, I just don't see, how it "ruins your accelerated decompression". At most, it's going to add couple of minutes of deco time. It's not like you suddenly on-gas a whole bunch of nitrogen when you swap to air for a minute. In fact, when doing long deco on pure oxygen, you should be doing air breaks anyway.

Hi Achim, Excellent video ! I can see some great mastered skills ! Just one question... Why isn't there specific nitrox regs on deco tanks ? And, I don't see any transmitter mounted either on your first stages for your computer. I believe there is a good reason for that... Is it not recommended as technical dives? Thanks.

[@edwardlyden7902]

Don’t use transmitters when tech diving they are a failure point. I am sure all his Regs are oxygen rated but are not marked like in recreational diving plus you won’t see nitrox stickers on his tanks but will be marked with specific gas being used his back gas,stage bottles can be used for different gas mixtures

Drysuit? What is that?? (Before you get a real Debby Downer) it's a wetsuit. (I've been hammered and hammered for a misspelled word,I can only imagine a while wrong word)

[@shiftyshrimp5930]

@@historyhunter5215 That is definitely a drysuit- both wetsuits and drysuits exist, you may have been criticized in the past for misidentifying one. You can tell because he has inflate and dump valves on his chest/left arm. This is where you fill/empty your drysuit with air, which doesn't happen in a wetsuit. Another way to tell is by the appearance- wetsuits are skin-tight, whereas drysuits can appear "baggier". One functions by trapping a layer of water against your skin (wetsuit), the other works by adding a layer of air against your skin (drysuit). Drysuits are much more expensive, require more skill, and are better suited to very cold/long dives. Hope it helps!

[@MrTzompy]

[@strolchtv86]

One question, why do you actually decompress at 6m with 100%O2? Isn't it dangerous to leave the partial pressure at 1.6 as standard? You should never go higher than 6m because of the decompression, which is why you should stay a little lower at 6.5-7m, right? The partial pressure there is then 1.7, which according to the CNS table you can only withstand for 10 minutes. If you accidentally sink 1m, you quickly reach 1.8, which you can only withstand for 1-2 minutes. Wouldn't it be smarter to decompress with 80%O2 in the upper stops to be on the safe side?

[@klixtrio7760]

I noticed you clipped the gate facing out. Is that important or is it a personal preferenace?

[@darrencibis]

I notice he switches back to bottom gas between each gas change. Doesn't this mess with deco? Especially if using a dive computer?

[@christophhubner5702]

what are the tank sizes? Looks like 40 cuft. for Oxygen and EAN50. Why this small size for EAN50?

[@sidemountsarge]

Calculate your gas requirements and that will dictate the cylinder size. Graham Blackmore's youtube goes into this nicely.

[@cbutube]

What make is the drysuit? I've been trying to find an orange one for ages!

[@rixogtr]

Hi, when you prepared for cleanup and oxygen stage, you stored 21metres stage and went for regulator on your neck (black hose) right before you started switching to oxygen cylinder, what did you breathe between 21st and oxy st ?

[@russell3038]

50% - MOD of 17 meters.

[@thomaschilcott]

Between the 50% (from the cylinder marked "21") and oxygen, he went onto back gas, through his primary regulator (ie gas from his twinset, probably trimix for a dive requiring 2 deco gases and a bottom stage). It's fairly standard practice to return to back gas when switching between decompression gases.

[@B4nd1tCons]

What’s the idea behind gloves with the fingers cut off? Why not just wear no gloves? Or is there a reason.

[@sidemountsarge]

insulation if somewhere warm but with a long bottom time, while still giving you better tactile feeling compared to full gloves.

[@Kimdss7123]

What is the pin name in the video?

[@markwalter330]

I have a very fundamental question about the overall procedure you use. Why do you nose clip the bottom stage directly to your hip, rather than either clipping it to the leash or swapping it for the O2 bottle on the leash? In your procedure, it looks like you have to work around that nose clipped stage several times. It seems if you did the swap it would be a one-time procedure and then you would have both deco gasses up front and ready to go for the rest of the dive (no additional bottle moves).

[@CoastalDevelopment]

HI Mark. The empty BT STage on the leash is too bouyant and behaves like a dogtail. on the hip it is very stable. The whole procedure is based on the idea of not handling full stages to minimize the risk of droping them. the only full stage I move is the O2, which is the leas critical gas. haveing only one stage in the front also minimizes the risk of switich to the wrong gas as there is simply only one :)

[@jeremyhobbs7428]

It seems that when he is asking the buddy to verify the mod on his gas switch, he is using a specific hand signal. Is this the case? I've never seen this used - we just signal our buddy to watch the switch and may point to the mod sticker assuming the buddy will verify. However, I can see some value in having a hand signal, especially if you for some reason wanted a buddy to verify the mod on a bottle at a time when you weren't necessarily doing a full gas switch.

[@nunogirao]

What do you think of tagging the 2nd stage regulator with the gas type, so you can visually be sure you are switching to the right mixture? With so much hoses around, it seems easy to route the wrong one. Just an idea.

[@Yggdrasil42]

nunogirao many people do. Maybe he does too. Hard to tell in the video. Doesn't mean you should skip the visual check though.

[@sidemountsarge]

Buddy verification. you'll notice that he's stowing the used gas reg away, ascending to the required depth, confirming the cylinder is marked for the depth, verifying the regulator he's deployed is the correct one, double checking with a gas interruption (which also verifies the cylinder is functioning and has gas), before breathing from it. All this while he has his buddy/team members watching over to confirm/prevent breathing from the wrong cylinder.

[@billy2141]

Some people like to use different brand or model 2nd stages for that reason, others use different colours but verifying the cylinder and tracing back from the 1st to 2nd stage is the best way to make sure.
