Taking IANTD Deep Diver course in preparation for Advanced Nitrox and Deco procedures. To me, manual is not very well written and leaves a lot to be desired. Anyway, instructor sent me a question(s) that I can't answer.
Q: Dive plan is 32% for 20 minutes. Don't exceed 1.4 PPO2. How deep can I go?
RMV is .7 and I want to know how much gas I will need.
Use 1/3s, 1/2 plus 200 or rock bottom
I know how to calculate SAC, RMV, find ATA, MOD, rock bottom rule of thumb, IANTD 1/2 +200, 1/3s but I don't know how to answer this. I found 111' as MOD for 32% by just trying several depths on my calculator but this is like hunt and peck and doesn't allow for exposure (20 minutes)
Help please
