"If your scuba cylinder lasts 90 minutes on the surface, how long will it last at 60 fsw?"
Sounds like a trick question to me. How hard am I working? Did I use it to help me get past the surf zone?
I don't recall reading anything about this in my Nitrox manual, can someone please explain what caluclation they are looking for? Is there a calculation that, when you toss in the depth (or ata/bar) you get the difference in what your tank will deliver at 1 ata?
