Uh, that's why we're having this discussion. If I give a thumbs up then the message is "end the dive." That's pretty clear. My buddies know it and have agreed to it. If I get a thumbs up from you I have to start some guessing game as to which of the ascend meanings you mean... who's communicating in a clear concise fashion and who's sending mixed signals????Walter:Perhaps you should actually communicate instead of going off half cocked?
