DIVING LIKE A BOSS - Descent & Ascent

▶ Check out my gear on Kit: kit.com/Conque...
Someone suggested to rename this video to "I know this is crazy but this is what I do and I don't suggest you do it but please enjoy watching". This title is too long but anyway he's right so I put that info in the description.
DIVING LIKE A BOSS.
Lesson 1: Descend / Ascend
This video shows you how to deal with deeper water and how a quick ascent can save a lot of non-decompression-time. Don't try this on your own, both divers shown in that video are professionals, between them more then 35 years of professional diving experience.
This video was taken at St. Johns Island (Red Sea, Egypt) in April 2012. Assisted by the North Shore Divers Europe.

[@Angelo.Villaschi]

Thank you for this video. Now I know to avoid diving with North Shore Divers Europe like the plague. Congratulations on not killing yourself. Nice to see you ascend with your buddy staying on the bottom. Oh, and leaving a bit of cable tie plastic tied to the rock: how considerate of you to leave plastic rubbish behind! I only hope most divers who see this are smart enough not to copy this ridiculous behaviour!

[@conquereroftheuseless]

It's not possible for you to dive with em. So no worries. Cable tie is normally used to repair broken corals. BTW how many garbage are you leaving in the oceans? Surely nothing right? Fool. RTFM: "Don't try this on your own"

[@conquereroftheuseless]

anvill72 Without any insults: the buddy is fine and will always be fine. We work a lot for some NGOs, coral repair, shark tagging and catalogue dolphins (in the Red Sea). Actually we have the biggest dolphin database in the world with pics from above and under water. There's a well known TV station in Europe which broadcasts some stuff of us 2-4 times a year. Some NGOs call us (a team up to 20 divers) for diving projects and other stuff around the world (Red Sea, Malpelo, Cocos, Komodo, etc.) And now to that dickhead stuff you wrote: I'm the same to you as you are to me. So don't act like a girl. What you saw in the video is possible in depths between 60 and 25 meters b/c of Boyle-Mariotte. The distance between my buddy and me was to show you the no-decompression-lime difference: he did the same dive and had no more NDL while I had some minutes more. Newer computers have models which regard deep stops which has an impact to your NDL. Your turn.

[@kevingumfory]

Dunno whats worse. The content or the music. The music won't kill anyone.

[@conquereroftheuseless]

Will ask Quantic if they can produce better music for you.

'The Key is to descent as fast as you can' = Perfect disaster ready to happen. Not such a 'boss' after all...

[@conquereroftheuseless]

peculiar boast but alas

[@wizzessex5308]

Buddy looks to be 50+ feet away messing with his camera ?! - That's gonna do you a lot of good with any equip failure at this depth!

[@conquereroftheuseless]

True that.

[@dandcc9192]

This is so risky. You are supposed to come back up if you feel narcosis, not slow your breathing to slow it down. More like "How to cheat procedures to gain a tiny bit more bottom time and depth." 55 meters???? Recommended maximum recreational depth is 40m! Thank god the bottom where you are diving is actually 55 meters. What if you were diving where the bottom is much deeper? The Guam Blue Hole is 90meters deep. What if you were descending this fast and check your depth or add buoyancy one second too late? And you say in the comments it's emergency only? No, in what kind of emergency do you have to descend this fast? You don't breath less to stay away from toxic air, you are supposed to keep within the limits so it doesn't get toxic in the first place. That's like saying, to not die, you drink only little poison. Instead staying away from poisons altogether. At best this is the way to go to set records, but it is not recommended practice and you know it. Don't make it sound like it is. If you want to set speed records, you drive as fast as you can. But that doesn't mean this is the right way to drive for commuters.

[@conquereroftheuseless]

Dan DCC91 Sorry mate. You didn't get it.

[@radivmoe]

This video has so much wrong.

[@dee1476]

Right... I thought my knowledge was wrong while watching this. Had me scratching my head like WTF

[@crash1989]

Came for the video, stayed for the music.

[@rdinmaho]

Nice one Joe, just shows how things can be done if all is taken in consideration. By that I mean experience, knowlegde, skills and a seriously fit body. I completely agree that one should not do this if they lack one or all of the above but great that you have taken the time to show that it is possible. Happy diving and stay safe... rgds..

[@rpdrums11]

+rdinmaho dude, really don't even try this thing.

[@rdinmaho]

+Rene Perez By no means I am going to try that. This is not for me. Thanks for your concern. Much appreciated. Rgds...

[@conquereroftheuseless]

+Rene Perez you got some nice vids on your profile mate!

[@alpalbostan4077]

diving beyond limits with recreational gear is not a boss style...ascending with inflating bcd not seem to be a good idea as air in bladder will expand as you ascent .And as you have 3 minutes more you dont have to be too quick for ascent.

[@conquereroftheuseless]

True...in this example we have 3 min non decompression time left. But this has nothing to do with the 3 min left - we have the same profile even if we have the first stages of decompression time on the computer. Air expands when you ascent? Welcome to Boyle-Mariotte ;) There is no reason NOT to use the inflator. 99% of all divers don't have the right taring. Taring with the BCD is absolutely correct depending on the depth you are. The deeper you go the more BCD you need. And btw the gear is not as recreational as you think ;)

[@AvidDiving]

TheRealJoeFertig I call troll..... or just really ignorant :/ ima say ignorant troll. but defiantly trolling though. whats so not recreatinal about your gear.... oh wait, nope your just trolling. forgot there for a second.

[@ah1471981]

TheRealJoeFertig Wow, you really must be a troll. Mares regulators, aladin computer and al80 cylinders, zero redundancy, zero chance of any recovery in a failure. Its entirely recreational. Nobody with two brain cells would ever ever ever think of ascending by putting air in their BCD.

[@conquereroftheuseless]

AvidDiving Best answer I read for a long time. You're right, it's all about trolling. An the music ;)

[@conquereroftheuseless]

Ashley Hiscock Well please tell me what is wrong with that gear in 30° celsius water?

[@TheSmileyTek]

What was the "mission"? A short deep dive and some ties? Just curious.

[@conquereroftheuseless]

A short deep dive with a quick and short bottom stop and quick ascent.

[@ilivetoflyxD]

Why are you leaving plastic behind?

[@conquereroftheuseless]

This plastic is not floating and will not harm wildlife. It will be overgrown in 1-3 months. We use it very often to fix broken corals. Can send you pictures of progress if you want. Thanks for your comment.

[@pu3shahidah]

how to ascend exactly? some people say it’s dangerous to use the inflator bcs it will go fast... then how to go up without using inflator?

[@conquereroftheuseless]

simply don' trust people who say "don't use your inflator for ascending".

[@dive-sar3361]

BOSS = Bag of Stupid SCUBA in this example!

[@conquereroftheuseless]

Mate take a happy pill. You look a bit skittish.

[@brois841]

Just curious as I'm relatively new, what is actually wrong with this video? Lots of comments saying things are unsafe without explaining why. Seems like everything was done within limits. Some people complain about the quality of the gear - as if you have to have a certain brand to dive deeper than others. Issues with buddy separation, but clearly they aren't performing any major tasks underwater... get down, attach a zip-tie, go back up. What's with all the talk of killing yourself and so on? Serious questions.

[@conquereroftheuseless]

Hey mate! You have correctly recognized the three points that are taken up by the users here as dangerous. You are absolutely right in your assumption that you don't need any special equipment to safely reach the depth you are diving here. It is true that my buddy is a few meters away from me, but that does not matter here. The people here are much more concerned about the diving depth, which is generally due to the fact that everything below 40 meters is classified as too dangerous for recreational divers. This is only an actuarial limit. The personal limit for diving depth is different every day. In the video shown here, I want to draw your attention to two things: 1. When you dive deeper than 30 meters, you should breathe as little as possible. But that does not mean that you should hold your breath, but rather that you have to extend the pause (inhale - exhale - PAUSE). This slows down the nitrogen narkosis. 2. If you ascend from these depths you can do so with a higher ascent rate than the normal 10m per minute. You can do this until you have reached half of your maximum diving depth. Example: you want to leave your maximum diving depth of 45 meters, so you can now ascend up to 22.5 meters faster than with 10m / minute. When you have reached the 22.5 meters you stay 2 minutes in this depth. The faster ascent ensures that you do not become saturated during the ascent and adds some non-deco time back to your dive time. This procedure was mainly used for diving in the 1980s, when diving computers were not yet widespread. It still works today and all guides / instructors from my base dive like that. But of course professional diving youtube sees it differently;)

[@gracinvicko]

Why not do a deco dive with a cave fill, you compleatly avoid both the co2 narc and cns problems from low o2 sats in high pp.

[@conquereroftheuseless]

I have no experience with cave stuff. Thanks for your comment.

[@homeworkpictureshq]

Nice video

[@conquereroftheuseless]

thank you!

[@kebosatu]

I think the intention of this video is showing how to make a deep dive (in certain reason) without having deco. Few feet away from buddy always happens during dive, the risk is higher even during leisure. just that this video happen that the other diver seems not paying attention well. but I still get the positive point. Also maybe the title sounds like you guys trying to show off... well no offence intended. I still like it.

[@conquereroftheuseless]

kebosatu totally true that the buddy is not paying attention while ascending - but there where other divers of the team which watched out for me. And yes just wanted to show how to deep dive without deco. My buddy for example had deco after the ascend but I didn't manage to make a shot of his computer.

[@dive-sar3361]

130 FSW max 'No Deco' depth for Sport Divers, plus no mention of equalizing which sets the descent speed, not 'as fast as you can' to maximize bottom time!

[@conquereroftheuseless]

An experienced diver equalizes automatically like a professional football player does the pass without thinking. It's like breathing. But it looks like you need to spend some more time under water to rise from your rookie level to something above rookie^^

[@ah1471981]

TheRealJoeFertig Is that why you're constantly bringing your hand to your nose? Also, experienced divers can't descend so quickly on helium or on rebreathers. You're talking out your arse.

[@conquereroftheuseless]

@@ah1471981 do you see any rebreathers or heliox in this video? Looks like my arse knows more than your head.

[@nigelhewitt8925]

How can you be narked out of your head at 55 feet? It's warm, gin clear water with no obvious current, it couldn't get easier. How can they do it so wrong and think it's so right.

[@conquereroftheuseless]

55 feet?

[@burfakb2290]

You advise to breath less in the depth which is very bad for you. CO2 builds up more as you go deeper and you should breath regularly and deep. Why do you tie stupid plastic things underwater? I'm sorry but it's stupid to do something like this.

[@conquereroftheuseless]

Burak Birgül your breathing advice is absolutely not true. Please consider doing some diving lessons before you post something like this. For the ties: we are used to do reef repair since 2008. A cable tie never does harm to the ocean when it's fixed.

[@juliosorio1]

If you have credential you should lost it you must be crazy

Here's something more practicable for you: kzbin.info/www/bejne/epPCn2t4jperqdU

[@Alastor-i9w]

MOD of 21% = 52m max Dive depth 55m pushing your cns limits no?

[@conquereroftheuseless]

+Paul McNaught MOD depends on the oxygen partial pressure which starts by 1.2 (47 meters) and ends at 1.6 (66 meters). But... an oxygen narcosis caused by 1 minute duration at 55 meters... really?? Now your turn: you surely know someone who knows someone who has died or some other freaking story...

[@Alastor-i9w]

+TheRealJoeFertig Suit your self mate. dive to 55m as much as you like on air. Youll be a statistic soon enough

[@conquereroftheuseless]

Paul McNaught nice words thank you.

[@Simonowicz.Iljanowicz]

Are you sure? I think he is within his MOD and and not pushing his CNS. Most people are diving to a maximum PPO2 of 1.4. This is considered a safe limit that an experienced diver can dive up to without need to build in extra contingency. PPO2 of 1.4 is reached at a pressure of 1.4/0.21 = 6.67ata In seawater, 6.67 -1 * 9.8 = 55.5m In freshwater, 6.67 -1 * 10 = 56.6m

[@gradyboger382]

What is this

[@conquereroftheuseless]

Everything.

[@Simonowicz.Iljanowicz]

Interesting video which, on the whole, I am glad you posted. Reading comments, it is clear you know what you are doing and have a lot of experience. If you want to push limits like this without endangering others then it is your choice. Let's not forget how much people pushing limits has contributed to scuba diving. I learned several things from this video that I wouldn't have otherwise known. Of course, diving schools do not teach such things. Will I ever put them into practice other than in an emergency, absolutely not. Is it good to know and understand the science, of course. My issue with this video is that you have edited it in the style of an instructional video. The captions are phrased in a way that suggests you are telling people what to do if they would like to replicate what you are doing. Had you styled it as 'I know this is crazy but this is what I do and I don't suggest you do it but please enjoy watching', then I would be all for it. You even called it 'Lesson 1'. At least change the title!

[@conquereroftheuseless]

Simonovicz thanks for your comment - I put your suggestion in the description! Finally I have some time to answer. Of course this techique is for emergency only! The main thing is to have a 1-2 minutes stop at the half depth of your diving trip after doing that - AND - you have to do the stop at least at 20 meters of depth. Don't push further cause the bar ratio is different espacially from 10 meters to 0 meters. In case you are a dive guide you can use this technique if a student has panic and tries to get surface as quick as he can. You know you have to follow him and stop him from doing that but how do you want to manage this with a 10 meters per minute ascend ratio? Impossible... For all those negative comments here: the members of this diving team are helping NGOs year by year doing difficult diving stuff... and we dive like this since the year 2000. None of us has any injury. I can only give everyone the warmest advice to use the BCD right: inflate it when you reached your max depth to stay there and do not use your lungs because every breath you take is toxic (with regular air deeper then 30 meters of depth). In shallow waters I keep my BCD completeley empty and tare with my lungs only. in 99% of my dives I use a 7mm full body neopren (Oceanic) with just 2 kg of lead-weights - that means the BCD has to be empty otherwise you're unable to descend.

[@geralddy1022]

Wow

[@conquereroftheuseless]

[@ellakoachway5232]

what the hell is with the plastic zip ties???

[@conquereroftheuseless]

used to tie up broken corals so they can grow again. After 3 months the plastic os completely overgrown. In this video it is just a test for your brain and motor function. In depth everything works slower.
