R.I.P.
Don is right, watch your dive buddy for no less than 30 seconds after dives, I know most will say "yeah right" and that it is simply impossible to always watch your buddy and sometimes it can be frustrating based upon conditions I know, but, it can mean the difference between life and death. Spearo's are diving way to frequently from swb's and it can be stopped if we take a little time to buddy check more often.
I'm sorry to say that I do not practice what I preach as I dive alone allot, it is the nature of my blue water diving sorry to say. I have never lost a fellow diver on my watch but have saved a few.
I look forward to finding some one to dive with some day to help me watch my 6 on cliff craws and wrapped deep fish.
Cheers, Don
