Its tragic when we hear about losses of this nature. This is a sport that we as a community have come to love, or we wouldnt put ourselfs through all the work and stress involved to persue it. Talking about assistants, when I was in the DM program the dive shop that I was training through did a lot of classes in the divers park in Avalon on Catalina Island. There were a lot of instructors there without an abundance of help. I was shared, almost passed around between several classes, I had a lp 95 in shallow water as is expected for OW classes and just stayed wet for 2 or three class sessions at a time. Got out and got a fill and wet again. Its hard to get help when pay isnt included in the process. As for the unfortunate woman, no one has even considered the possibility that she may have had some kind of medical event like a stroke and just lapsed into state of unconciousness. I'm not saying that thats what happened but it is a possibility. We as the diving community wont know until the coroners report is made public. Gods speed to those touched by this tragedy.
