How is air the best mix for 65ft or shallower?
How did you come up with 20/40 to be the best mix for depth down to 200ft?
And since you brought them up, what are the best mixes for 200 to 250 and 250 to 300 and how did you figure them out?
Why do we care about the tank size if you know when and how to come up? Plan your dive, dive your plan, right?
