This diver is a Pro and knows his equipment and DECOM steps like the back of his hand
I've been UK diving for about 15 years with BSAC. That was beautiful to watch. Way beyond my Nitrox twinset. Excellent trim, clear signals and at one with your kit.
That was the key statement there: "at one with the kit" no way to do it smoothly unless.
Clear signals, except this one: th-cam.com/video/ATfl-ou2_Yc/w-d-xo.html
Very well put..
Damn, this guy's good...
That was neat. So clearly and professionally explained. Well done!
Every video I watch from ISE I learn something , I find my self watching the same video several times and each time I watch it I find something new or something better than how I do it.
That was really impressive, mad respect 🙏🏻
You can't buy class, Achim is an Elite diver !! 👈🏼
Pro, excellent control and clear signs, much appreciated.
Knows where every clip and lanyard is. Such a great control and execution. Very inspiring.
I watched this video more than 100 times to try to figure out how do you kick the leash to fall of in such a way ?
Magnificent control 👏🏾👏🏾👏🏾
Those are some crazy trim and buoyancy control skills. Multiple level stops with no reference point with perfect trim. I will never be that good.
Scott Gustafson Maybe you just have to Try try try try and try and finaly you will do it without Problems
Great buoyancy control.
Very professional
Nothing short of mastery. Beautiful.
Watching this video...makes me realize I need some better dexterity dry gloves. Very nice job here ! Very clean.
RJ Giddings his gloves have no fingers

Very well demo’ed. Thought about getting into tech diving but just didn’t want to get bogged down with all the tech. And certainly added risk. But do appreciate the skill. Thanks.
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.
Great video! I would really like to see an equivalent video for a CCR bailout using 3 stages please
Not a word, but lots of info. Thx much
Nice video! Clear calm signals and no hesitation. This man is pro :)
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! 👍
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.
This is so interesting to see you have so many tanks. I thought going into doubles is such a bulky way of diving, but now I see that you have several which is interesting to say the least.
Could you make a video on how to make the leash that you use to attach the third bottle that is behind your backmounted tanks?
Amazing. One day I hope to be half as good as him. Respect.
we need to all keep getting wet and practice for ever
@@arroyodflint7114 right you are! Time in the water. No substitute for it.
Great skill display. Very well done. First class diver.
Thank you for the excellent demonstration .Very pro procedure.
And I'm struggling with just one deco tank. But he inspires me!
Amazing
Nice style.
Sharp signals. Learned from your dive.
Cheers bud.!!
very smooth .. awesome
Wonderfull, perfect.
Ein wirklich tolles Video. Zweifelsohne tauchtechnisch gesehen super, aber eben auch, weil es ansonsten kein Video gibt, welches dasselbe zeigt - ein mögliches Szenario mit 3 Stages. Ich sehe immer nur Videos zum Thema "Gaswechsel". Hier endlich mall einen "kompletten" Tauchgang, super!
Can only hope to achieve this skill level . New diver here and want to start out correctly .
You must be making good progress by now! Not so new anymore
Beautiful to watch....I need to practice more 👌
Excellent!
Holy Crap! You are a Tec God!!! I want to dive with you.
Thanks - but no, I am not. But You can dive with me :-)
Insane skills
smooth and clean good job
Amazing - such ease. Love to reach this level.
pure poetry
Great video, yeah the feel from the finger tips, methodic and cool.
Eines der besten Videos dazu!
Nice trim.
hi Isaac, the light in the Video is from finsub.
Thank you!

Must be GUE trained. Great Vid showing how it is done .
Awesome
Gold Job. Gold skills. Lets forgett about the Hand sign on 2.05 😉
Hes going up to deco depth, and signaling that
Fantastic. Thank you.
WOW! Just perfect!!!
Majorly Awesome!!
great effort under the water (y)
The complex mess of pipes, lines. and tanks and one mistake could kill you. What a crazy sport!
Nice video. Very professional 👏
Wow!! Is this guy an instructor trainer??
How perfect neutral buoyancy
I honestly was amazed by his buoyancy control.
Superbe maîtrise des ''relais''...Bravo. Présentation superbe et belle sono.
I watched this video million times and still can’t figure out how did you kick the leash so it floats downwards?
verry nice video ! watched it a few times already! amazing skills ! keep up the good work !
Brilliant! Would be interested in seeing how you organise the clips on the left hip dring, ie. in what order and why. Maybe something for another video?
mac_3k usually pressure guage on top, and leach on bottom. The other stages in common order in between.
Relieving to see proper hand signals on a TH-cam diving video.
I was taught pinky to indicate deco sign, but he uses a hawaiian hang loose signal. European?
@DaBoogie Thumb up means "end dive" or "start ascent". If you're only doing 18m PADI easy dives of course you will signal thumbs up when you are at 5m before surfacing.
First time I seen this one
As a digital nomad constantly travelling I can’t imagine the expenses I’d incur carrying that much stuff in my luggage. I already carry around 70 kilos including my normal luggage being an OW diver.
Carry your first stages in your pockets on the areoplane
great video, nice skills. thanks.
Elegant
Dont gomero, TH-cam i love your Chanel
Toujours aussi pro à regarder
Nice video no crazy music clear information
Very amazing trimm & high professional! It phenomenal! I would like to know how many dives you have! The most epic scene for mee: 4:20, when he does the kick! Und mir ist aufgefallen, dass du der deutschen Sprache mächtig bist! Finde deine Skills sehr beeindruckend!
Respect...do you sometimes dream of diving? 😂 thanks for Spareinlagen your skills
Awesome stuff
Really nice. Such a pleasure to watch. I am curious though. How easy can you do this with dry gloves on?
th-cam.com/video/urT4WtKQaDw/w-d-xo.html
@@CoastalDevelopment Thanks for sharing!
Checking deco plan when it s on ur arm is easier and faster. Good diving skill indeed
I’ve never seen a leash leg before, dumb question, what is it?
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.
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
@@edwardlyden7902 there would be the possibility he treated his gear at a specialized scuba diving store maybe, which would then not be specially marked as usable with nitrox but still be fine
That's diving!
Can I like it a thousand times?
Cool! Thanks for sharing ;)
Perfect !
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.
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.
@@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.
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.
@@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.
@@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.
Could i know the model of drysuit and fins?? Thanks
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)
@@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!
@@shiftyshrimp5930 It is a Black Pearl drysuit
Super pédagogie. Again...
Good
you got great skills.Why are you going back to your back gas when you switch between your 50% and 100%?
Nicely done. Not my cup of tea ...mixed gas diving...more for others I believe.
Like the suit color.
how much extra weight do you need to compensate for the positive buoyancy of an empty stage?
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 !
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.
Is the procedure the same if you had two AL80 cylinders and one AL40?
I noticed you clipped the gate facing out. Is that important or is it a personal preferenace?
What’s the idea behind gloves with the fingers cut off? Why not just wear no gloves? Or is there a reason.
insulation if somewhere warm but with a long bottom time, while still giving you better tactile feeling compared to full gloves.
Scubapro A700 with Venturi system
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?
Aluminum tanks are pretty neutral which is why they are used for stages. Steel would be a problem.
Отличная работа! С уважением из России!
I notice he switches back to bottom gas between each gas change. Doesn't this mess with deco? Especially if using a dive computer?
man man man... DAS nenn ich mal taucherisches Niveau!
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?
I noticed you have white regulator hoses on all your stages- is this intentional? If so, what's the reason for this? I guess it can make it easier for your buddy to quickly identify that you are not on your back gas?
Great ! Thank you for making the movie . One question: did you not say to store the primary light on the inside of the D ring ;-) ? I saw you store it on the right side of the D ring : twice. Just wondering? But great movie. Thank you. Your movies inspired me to do BOE+ training with Alain Dobbelaere. Will continue with ISE.
HI Gerrit, thanks for your feedback. if there is no reg I can clip it from outside. if then the reg comes on top - it basically moves to the inside. (hope this makes sense)
How does this work logistically? How does one get all these tanks to and from the water? Not hanging off to one side.
Gear lines.
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.
what are the tank sizes? Looks like 40 cuft. for Oxygen and EAN50. Why this small size for EAN50?
Calculate your gas requirements and that will dictate the cylinder size. Graham Blackmore's youtube goes into this nicely.
What is the pin name in the video?
Wow professional.
how much extra weight do you need to carry it all those empty bottles towards the end of your dive ? you must weigh a ton before you even get down to start the dive ? and then how do you carry enough air at the start of the dive in your BCD or an extra pocket to counteract being too heavy?
