What I have:
A single AL80 DIR set up. Diving 7mm wet.
One of the problems I’m running into is that with a conservative rock bottom (amazing what stress will do to your breathing) the 70+ dives are severely limited, not because of the ndl, but because of the amount of working gas I have.
So what? They are still dives. In San Diego you should be able to rent a larger steel single.
