In an air share, you reach a point on the exit where you know you normally use 500 psi to exit on your best day and there is 200 left in the tanks and a difficult restriction ahead, or whatever would make you certain both of you aren't going to make it. You are 100% certain, and not only are you 100% certain, you are 100% correct. You may not even make it and it would take all of your skill, all of your tricks, all of your experience, and to make it out would be a miracle in itself at this point, but you are good enough, that maybe you just might, but in that air share there is absolutely no way. It's not Ginnie. It's not a popular cave. It's in the Bahamas. You know the only three cave divers on that island and they are not planning to go diving that day. Are you really a coward? Are you cutting and running?
Thanks for this bit Trace,that's exactly how I interpreted your first post,hence my reply.
