Here is a lesson on reading my dive computer. I'm at 81 feet down. At this depth I have an estimated 30 minutes until I get down to only 500 psi of air left. However, I have only 18 minutes until I get into decompression status (deco) where it is not safe for me to emergency ascend right to the surface. I am supposed to make a 'deepstop' at 46 feet (hold about there for a minute on the way up). I have 2003 psi of air left (lots) and the dive is 16 minutes old.
