Deep Diving 108 feet w/ a single AL 80 (Air.) No redundancy.

Yeah. Last month we did several 30M+ (deepest was 36M) on 12L tanks. I just made sure I stayed out of NDL. When my NDL go to single digits I’d start ascending a bit

Did you make a proper min gas calculation? With a sensible degree of conservatism?

30-36m within NDLs isn't necessarily excessive on a 12L single tank. At least not if it's 232 bar. But you should know what you're doing. And you ought to do the proper maths.
