I have to admit that I've been watching the "Cobber's trimix" thread for the
past couple
of days before posting. It just got the better of me tonight and I had to say
something.
First, Cobb admits to diving the "Eureka" off the NC/VA state border with
**mix** to
determine the difference between a "deep air" buzz and trimix. Swears he saw
some
difference. Come on now JIM...the Eureka's 116 fsw (35m) deep with an
occasional wash
out to a max 118 fsw (35.9m). NOBODY'S definition of deep air, or **deep
anything** is
in that range. Using Tx on a 116 fsw (35m) dive with a low **home brewed** FN2
put you
at an EAD of what....35 fsw (10.6m)??? How many of us out there notice the
"buzz"
difference between 35 fsw and 116 fsw?? Really now!!
The average REAL mid-Atlantic Tx wreck dives (Monitor, E.M. Clark, St.
Augustine,etc)
are lying in the 240 to 260 fsw (+/-75m) range and you should be on your 6th+
**deco
stop** before you hit 35 fsw. Matter of fact, you're first deco stop on those
dives
would be below your max depth on the "Eureka". So maybe you got the
"pre-requisite"
number of gas switches in to make it a technical dive - but on the
Eureka...who's
fooling who?? Who cares??
I guess I'm an idealistic gal and believe it takes more than equipment buying
savvy, an
understanding of tech diving lingo, and a keyboard to make you a techncal
diver. Seems
to me you should be doing the dives. Experience does matter.

PS: IANTD TX certified #560 ('95) and "grandfathered" out of the deep air
pre-requisite
by Billy Deans due to level of ACTUAL Tx experience prior to the IANTD course.
Now go
ahead - flame away...
