> SECOND IN THE EVENT THERE IS SUCH A MAJOR And Complex RESTRICTION > ENCOUNTERED THAT THE DIVERS CANNOT GET THROUGH IT WHILE SHARING GAS, > a situation exist that they must separate in order to get to a point > where it is possible to share gas again, Forgive me for asking what must surely be a stupid question - I have not been cave diving that long (three years, just over 100 cave dives). If the restriction is so major and complex that two divers cannot get out through it while sharing air, then why are they going INTO it in the first place? That seems like a recipe for disaster. If such a formation existed in the cave, then it seems like a different gear config would be required to negotiate it safely (i.e. side-mount or no-mount). And since that is beyond the scope of what is typically taught in a Full Cave class, then it seems a pointless scenario to discuss. > A third approach of course is do not teach anything for this worse > case scenario and if it happens to a dive team let them figure it out > on their own, under stress without having the benefit of a dry > rehearsal or thoughts as to how to address such a possibility. Or we could just teach them that if their plan involves a cave passage where they are likely to encounter a restriction of that type, then they should either (a) make another plan, or (b) call the dive when they reach the restriction. Again, I apologize if there is something obvious that I am missing about the situation. Please enlighten me if there is. -JimG -- Jim Greenlee (jkg@cc*.ga*.ed*) "Can you destroy the Earth?"
