Glenn, I wonder about so many signals to be used at ice diving. In SAR operation we come along with four basic signals, others are subject to divemaster's advice, depending on the SAR situation. The basic signals, defined by the National Accident Insurence Authority are: 1 pull - emergency signal 2 pulls - keep the line on Your left side (for search operation) 3 pulls - keep the line on Your right side (for search operation) 4 pulls - end of dive, going up The point is that the _diver_ has to keep the line tight, that he can feel direct contact to the line's man. The line's men can conduct the diver in all positions required, even at zero vis. OK, may be some point to discuss if the one pull emergency signal is missunderstandable (AFAIK the German Navy uses 1 pull for OK and a series of quick pulls for emrgency), but an OK signal isn't necessary as the diver has to keep the line tight. Anyway, in all cases of emergency all prepared algorythms have to be started: pulling in the line, sending the relief diver in, a.s.o. That's why there are no different stages of emergency to be signalized. Safe diving, Chris ------------------------------------------------------------------------ Christian G.
