But I would say that a cave dive at 285' for 4 hrs on staged scooters using your own tables is probably more dangerous. It is all a matter of risk managment.

I thought from what I have read that overweighting was a major factor in these fatalities. This is something their instructors should have covered.

Bill I have never advocated solo diving. I have never lost a buddy (knock on wood) but I have known some who did. Why not be ready for the uncertainty. Can you say that you absolutely know you won't loose your buddy, or how he would react? Self rescue is a state of mind as well as technique. A BT is about the same as a watch, so why is it a problem?
