If you were among the first batch of divers in the ’60s and ’70s or if you watch old school scuba diving shows like SeaHunt then you’ll know that there used to be animosity between the two different types of scuba divers; hard hat divers and open circuit divers. Today hard hat divers are limited to commercial divers but there are still two types of divers out there; open circuit and closed circuit. That and the hippie freedivers but we don’t talk about them so we don’t over inflate their egos…
As we all know scuba was invented by Jacques Cousteau and Emile Gagnan in 1943 that changed the world as we know it and allowed people to breathe underwater. But what most don’t know is that rebreathers actually predate open-circuit scuba. A patent application was made in 1878 for a rebreathing device known as the Fleuss rebreather, invented by Henry A Fleuss of Siebe Gorman that recirculated Oxygen and was used in England. A few tweaks and changes over the years but recreational rebreathers, closed especially, weren’t that popular until the ’90s.
Now we’re looking into rebreather failure points so most of this is going to be expectedly negative against rebreathers but remember that there are thousands of rebreather divers out there and many of these faults and potential dangers weren’t fatal thanks to good training, practice and a great mindset on the diver’s part.
So I’m Mark from Simply Scuba and Are Rebreathers THAT Dangerous?!

it took me entirely too long to realize that beeping sound was repeatedly in the video, and not my washer/dryer end-cycle alarm.
"Rebreathers are quiet when they go wrong." They are quiet when they go right too. When I see cave CCR classes I call them "Ent moots" as they look like they are doing nothing at all.
I will stick with my open circuit thanks mate.
SCUBA wasn't invented by Cousteu and Gagnan! They improved and copied existing equipment. Then patented that system.
These staff is for rich cave divers.
4 years ago me “I’ll never dive a rebreather too expensive and I don’t need to go deep” here I am now owning an rd1 ccr and I love it more than open circuit diving and I feel safer on my breather than I do open circuit he redundant back up is so much making getting home a non issue
Didn’t learn a thing about these, PADI certified
The first all natural rebreather
i dont exactly how they work but if you breathe faster than normal are you just gonna pass out
DAMN IT I spent 10 minutes walking around my house trying to find the source of that beep. I
I have many years on both OC and CCR. The trouble with OC is It’s noisy, expensive (gas costs in tech diving, my breather paid for itself in gas costs alone!), and so limiting.
I think that's asking the wrong question. What you SHOULD ask yourself is this: Do you need one? Because you'll either get it despite the risks or shouldn't even if it was safe.
Working on getting my rebreather classes done and eventually rebreather instructor. Would totally use them even after watching this. Proper training and carrying enough bailout gas is a must though.
Toured a dive chamber with my club a while back, when I was interested in going the rebreather route, and mentioned it to the doctor giving the tour. He just flat out said, "We never see rebreather divers in here. Absolutely never. The kit either takes care of you and you don't get bent, or you die. There really is no middle ground."
You folks should do a video about how to even get into ccr diving, and what's required of you as a diver. As an open circuit diver, I ain't got a damn clue.
I use a closed circuit re-breather for rescue on underground gold mines and have never had a problem but then again i have all the test gear, spare parts and training to make sure nothing goes pear shaped for my team. I can't imagine things are much different when someone is maintaining their own gear, if anything i think they'd be even more fastidious!
Ccr is in my future. Doing cold water tech dives and looking at trimix, a Ccr is the only way to make it affordable plus all the other benefits.
In Britain in the 1960's the sport diving organizations attitude to rebreathers was "Here Be Dragons, keep away" and they ordered their divers to never use them.
If you don't service your car on schedule or you have the attention span of a fly then rebreathers are not for you. You have to maintain it like a sophisticated race car and watch and understand what your gauges are telling you.
Put it this way. (From a rebreather diver). Everest is dangerous but many people mountaineer without injury. Open circuit diving to rebreathers are as backpack hiking is to mountaineering.
