Rebreather definition

We made the ascent as normal, and I learned from first hand experience that the rebreather does not need any diluent during ascent.

Instruction by a rebreather diver of trainee's on open circuit SCUBA is not covered under SAA Insurance.

So, I stayed just long enough to check that I and my rebreather seemed fully functional.

I try to avoid nitrogen narcosis whenever I can, especially since I began using a closed-circuit rebreather.
