George, you should give up on this---as long as Mount controls the standards
for IANTD, he can create far more rescue scenarios than any of us ever
could....I just hope he's up to rescueing all the new students wearing
double 112s, double 120's or double 190s---whatever hoover patrol setup  is
preferred right now at the morgue :-)

Regards,
Dan

P.S.
I think Tom Mount means well, he just wants everybody to be able to dive,
and he'd like all of them to be certified by IANTD :-)
But not everyone should tech dive. Fewer still should teach.  And everyone
who manufactures gear is not necessarily deserving of respect and kind
words---professional courtesy needs to be won. Tom really "wants" to like
all these guys ( mfgs like OMS) , and to be able to say all the gear out
there is good....Sorry Tom, in the real world, that's just not the way it
is.
