I don't think they are unsafe; I don't dive a rebreather because I cannot rationalize the extra risk for the dives I'm doing.
It's not a money thing at all, just a risk assessment thing...
Welcome to the Cave Diver's Forum.
Too expensive (initial cost to purchase CCR)
Too expensive (consumables to dive ie cells, sorb, O2 etc)
Training (Don't want more training or training is expensive)
Do not think they are safe
Too complicated (prefer simplicity of OC)
My buddies or team all dive OC
I don't understand enough about rebreathers
I have never tried one
I dive exclusively sidemount and don't want anything on my back
I only do short or shallow dives
I don't see a benefit

I prefer OC. For the dives I do I don't need CCR. I don't dive deeper then 200, I don't stay down for 5 hrs. Just my preference. Oh, and I sold mine!

I see you are an ICU nurse. Me too. I worked surgical trauma for a few years then now I'm in critical care float.Originally Posted by Diverlee
In pompano I would definitely be diving a rebreather! Great wrecks and a short drive to the caves.
If you want to see some funny redneck quarry diving check out my youtube account..

I votes for the cost options. I hope to overcome them someday soon, but until I am doing more deeper dives, consistently, where the price of helium would eventually offset the cost of the unit and training, I cant justify it. Yet.
Insert something witty and creative here_________________________.
Rebreathers are probably the single most annoying piece of gear you can buy, IMHO, because of the conundrum they put me in. As an engineer, I love that is a technological progression over OC (yes, I know it's older) but I don't dive one for a few reasons. On the one hand, cost. Cost for the unit, the maintenance, and the training. Also, I'm not convinced the technology is there yet. I want one, even though I by no means need one or even would make proper use of one just because of the cool factor.
I'm still waiting at least until CO2 can reliably be monitored, yes I know one unit does, but why don't the others? It's my understanding that a CO2 cell just won't live long enough in that environment?
It seems to me the Semi-closed RB is the most untapped market in cave diving. The RB80 appears to be a great idea but not many are using it I suspect because of the DIR factor. If you could build a safe, economical SCRB that would allow the average cave diver to use two 40 cu cylinders and dive the same time as a set of LP120 pumped to the begeezous belt you would have something.
Anyone using a GEM for Cave? Still too expensive but on the mainstream track maybe??
Yes, a lot of them are used in caves. In fact, that is what they were designed for.
Anyone have any pictures of a cave configuration (Not Sidekick) of a GEM, Gas planning etc?
My biggest reason for not diving one is that I have yet to do any dives where the complexity of doing them on OC made me think I needed to change something.
I don't want the hassle -- I don't want to haul or dispose of sorb, I don't want to disinfect the loop. I don't want to have to have a checklist to get ready to dive (the mnemonic I already use is enough). I don't want to relearn buoyancy control, and my trim is already bad enough
I've played around with a rebreather several times. The silence is fun; the rest of it is a hassle.
