cummings66:I suspect that the number of deaths is low in comparison to "normal" scuba gear and that it's so rare to hear of it that it sticks in the mind, thus the out of place comment made about training. In any sport or activity there are bound to be fatilities, just in some of them it's not very common.
The only way to truly evaluate whether or not rebreathers are more "dangerous" than conventional SCUBA gear is to look at the number of deaths in terms of the total population. Rebreather deaths may be rare, but (example only, numbers completely fabricated) if you have 10 deaths out of a total population of 500 users (2% of the the population) vs. 100 deaths out of a population of 500,000 conventional SCUBA users (.02% of the total population) then I think one could argue that statistically rebreathers are more dangerous.
However, having said that, this is not the thread for this discussion. My condolences to friends and family.
