Hi, I am a bit confused ... I believe tec divers just plan for 1 loss/failure at a time ... In a team of open circuit divers, each diver brings gas that he needs for the dive and also what he needs in case of a deco loss... but just 1 deco loss ... If I loose my deco, sure I still have enough gas to help myself but in this situation, I can't give any gaz to my buddy ... ISE way of planning gaz for OC dives seems different ... ? Kind regards
Why would you think your CO2 issue would be gone in just 3 breaths? If you have a CO2 breakthrough the physical effects of that won't be over in just 3 breaths of diluent, no? I appreciate you speaking about this though, thank you!
Thanks for the video. I have one question. You said "my right cylinder is for my buddy." I'm assuming the gas in the right cylinder isn't a rich deco mix? If you are diving with other CCR divers, do you put a long hose on your left (deep) bailout cylinder? If you are with other CCR divers, I would think it would make more sense to have a long cable on the deep bailout and a shorter cable on the deco mix on the right?
Its been 3 years since this reply but all divers should have 1 6-7 feet long cable for there buddy, OC or CC. CCR guys usually have backups of backups and even a 2nd rebreather as a bailout. But divers in teams usually have a planned team bailout in case 1 thumbs the dive. They have a team setup in place for plenty of oxygen
I am led to believe that a couple of breaths are not enough to gain enough 'sanity', if ever, in case of real hypercapnia. Why not having BOV plumbed to deep bailout in the first place then? Does BOV have superior wob than the high end OC reg for bailout in case of CO2 hit? ..questions from an OC tech going CC soon.
thanks. Well - it really depends on the situation - but generally the idea is to have "good" gas to make a proper decision instead of being forced to grab "some" gas. It is an option to plug the BOV to the Cylinder that actually delivers Diluent. That has the benefit of always having the same gas in the BOV then in the loop but depending on the model of the RB that may require additional plugging (and then can be an additioal source of trouble).
The co2 hit is the least of your problems in CC. It is unlikely and you’ve got indicators and if it does happen, you’ll feel it To many other things to kill you The descent is the most dangerous time on a RB Probably same as OC arguably.
i wouldn't say that it's "the least of your problems". in fact, it (probably) scares me the most. We don't have CO2 sensors like we do O2 sensors. there AREN'T always indicators and there's no way for us to measure CO2. all it takes is some over-exertion and you may be out before you know what hit you....
Matt G There are co2 sensors available but the temp stick to me is more reliable and less likely to give false readings. The Classic has no indicator after all. Not sure how many that killed with hypercapnia. Probably none if they changed the scrubber properly. I just think that with the temp stick is a pretty solid indicator, so best to worry about other stuff of which there are plenty To say that all it takes is a bit of over exertion i don’t think is right. If that was the case, there would be far more instances of dead CC divers
@@ianmackay999 wish I could fully agree. There were several close calls in my driving community over last couple years all linked to hypercapnia. None of the ops enjoyed the experience not being able to switch to bailout panting rapidly. All experienced and well trained divers at mod 3/full Tmx level - most of those caused by extra exertion during descent
As someone who has only ever dived OC, this actually explained a lot of things to me really clearly.
Super nice explained
Great explanation! Keep it up Achim!

Nice video, well done!
gg for the butterfly diver, ha ha, as always, great video
Any dive is decompression dive!
Very interested in rebreathers as an advanced open water, and it sounds very interesting, but i have no clue what he is saying 😩😱

Just want to say that imo in case of an emergency you should always at least let your buddy know what's wrong. People still die on CCR.
