So this is a curiosity question. I had the chance to use a R1 O2 rebreather the other day in a try it dive at local pool. It was a pretty cool experience and it prompted a question. Would one of these rebreathers be able to replace my conventional OC scuba for diving at recreational depths?
Here is my situation. I typically dive with a steel 120 and most if not all my diving is above 100'. I am getting older and father time is catching up with my back. at some point I will no longer be able to sling all the lead and steel. The CCR is much lighter than a traditional OC system.
I understand that because of the PPO of a pure O2 diving is limited to 20' and repeated prolonged O2 can have an effect on your lungs. But I heard from the guy doing the try it dive that the rigs can be modified to use air as a diliuant and work at greater depths.
My question is would this be a viable option? With a upgraded DR1 would it be a viable way to dive within recreational limits? With a system like this would it a kin to breathing Nitrox at a fixed ratio or would it would the gas blend be adjustable like used in other CCRs? This is mostly an academic exercise, but I would not mind being able to go out on my usual underwater bumbles, which normally range from 30-60 FSW without having tank pressure as my limiting factor.
