ok,rich I'll take your word for it.Maybe I'm the freak then,as I never
had any subtle symptoms until 130 & no obvious ones till around 160.
Ok,i guess it's possible that the pre-130 symptoms were so subtle that
i didnt realize i was narced,but if theyre THAT subtle,i cant see them
as being significant enough to be a main cause of the accidents we're
talking about.Different people,different tolerances i guess.I DID have
a friend that was so narced at 160 ,he said it was like an out of body
experience,but he was THE mst susceptible person i ever knew,and it
WAS 160.Acclimation is of course a BIG factor,as im sure you know,IF
youre diving regularly.My first dive to 160 was as narcotic as one
made several months later to 200 (I dont do that stuff on air
anymore..I wised up).Im not disregarding narcosis as a contributing
factor in these supra-100 foot dives,but i think there has to be more
to it,i.e. not a primary cause.Thanks for the info,tho...all i can say
is "narcosis above 100'..wow,who'd a thunk it?"
