Looks like a very successful dive, Jim. Excellent captures...especially the turtle!!! Just out of curiosity, how much air do you surface with?
I'm the same...500psi is a safe best practice! I had to share my 500psi one time in Cozumel and it made for an anxiety-inducing experience.Missy,
I aim to surface with a quarter tank left and I always plan for a three-minute hang at 15' at the end of a dive. In practice things don't always work out that way but it's rare that I run out of air at the end of a dive. Some divemasters are more conservative than others. I make sure that they know when I start to run low so that there are no surprises.
