Ok, I should elaborate some more.....first I made a typo, it should be 21 instead of 18 m. Since that dive was part of AN/DP course, we decided to go up to 15 meters and do switch there, to practice buoyancy control without visual references bottom would give us. It was not a deco violation per se, first deco stop was at 9m, but since you have better gas, Perdix would prompt you to switch, for more efficient decompression. I guess you could call it a deco stop, so you can switch gas,but.....btw. maybe we should stop hijacking this thread?By theory the stop should have been at 70 ft with a 1.6 PPO2 I have never had to deal with a situation like that.
