Another reason there's three sensors is that: sensor failing is rarely all or nothing. It will start reporting incorrect data. Having three sensors means that if two sensors disagree with a third then that third sensors is likely broken. In other words the sensors need consensus, which is why having an odd number is beneficial. You don't want 2vs2 but rather 2vs1.
I consider myself an experienced open circuit diver (albeit a little rusty), but never used a CCR. I found your explanation of rebreathers really helpful and has answered a lot of questions about rebreathers.
Manual rebreathers these days aren’t completely manual. Almost all use some sort of needle valve or something similar to release a measured amount of oxygen, depth compensated, to account for your metabolic usage. When properly configured you only really need to add oxygen or dil when your depth changes.
Are they not super rare? Outside of Kirby Morgan helmets I’ve seen in pics, I’ve been on many many dive charters and been diving for years with open circuit here in Australia and have never seen anyone with a full face mask before
Way off topic #askmark I just learned of a relatively new company (www.Newlight.com) in California that is attempting to replicate (in their plant) the natural process by which microorganisms in the ocean eat methane and carbon dioxide as food and turn it into a biomaterial called PHB (Google it). Since PHB is meltable, it can be molded to be used as a replacement for plastic, fiber, and leather. Drinking straws, cutlery, etc are dishwasher safe but will break down and be once again used as food if they ever make their way into the ocean. Thought you'd find this interesting.

I think I would definitely look into CCR if I go tec. High price helium will last a lot longer.
Thank you it was very helpful!
you also missed the kiss sidewinder for sidemount divers
Caustic cocktail on my first training lesson broke it for me. Never trusted the machine again
What sorb were you using?
Its all practice closing the loop
@@DEVINE.IMAGE. I actually had holes in mine-the loop was punctured and allowed water in
How did it pass a positive pressure test with holes in it
Bad instructor letting you dive a ccr that wouldnt pass all the checks that's the exact reason we do positive pressure tests before every dive
so you can manually adjust your O2 level while going deeper?
Great video thanks
You made a text feed for yourself for the video. Thats fucking brilliant. Great video. Thank you sir!
Been looking at the Dive Rite Optima eCCR. Anyone have experience with that model??
Is that an IKEA Shark to your left ? : )
Do one about full face masks
I agree
Definitely

Do you know what type is used by the military?
Draeger probably
Dreager for sure
Depends on which military and which job.
Draeger
Mk 15.5
Hiiiii
Good morning
