Subject: Re: streamlining of scuba gear
Below is what I said exactly on my web site about the death , there are two 
statements I make in the story that says it best and these are it.

1)I believe the diver called the dive as we were told, this was done 
because he had winded himself when he let go of the anchor line. The added 
drag from his gear in the current and excess weights on his ankles (all 
over) was too much for him to bear. He was not streamlined. The diver did 
not have the experience to just stop long enough to collect himself and 
breathing heavy, but not wanting to show he was in trouble gave the OK sign 
and went for the boat. He never stopped to relax and catch his breath. His 
own ego stop him from asking for help, he knew he was in trouble I think.
..
2) But even with this stand I have taken with this gear, the diver in my 
opinion would still be here if he had not let go of the anchor line to 
pass, his inexperience on this thing killed him.
