Mark, I figured it out : 75% of the strokes in Europe do the IANTD crap
with the isolator, the rest dive independents. 100% of the non strokes have
the deal figured out.

 There are those who got screwed by moron instructors, or influenced by
strokes, but then if they are not smart enough to see the obvious when it is
explained, they deserve to be in the "statistics", and eventually they will
be.

 Here is one for the strokes to ponder. I do dives none of them will ever
even understand or approach doing in their wildest dreams, yet I am the most
risk averse guy on this list, and the biggest safety weenie. When I started
doing the "insane" stuff, I had a family with little kids. They are now in
college. Do you strokes out there get the point? The point is you guys have
no clue , no system, no understanding of the game, and a track record of
Star Wars Bar Scene clusterfucks to prove it. You suck. You are an
embarrassment to those of us who will die of old age in this sport.

Since when did common sense become a failsafe in a difficult situation in
300fsw? - How much time would you waste if you just happened to turn it the
wrong way - and what might be the effects on your already strained mental
well-being when it doesn't turn off.  How close are you now to being in a
total clusterfuck?

Fully on and you can turn it only one way - done in a few seconds thick
mitts notwithstanding - if you can't do it practice! Wendell Grogan's e-mail
says it all on this front.  Then there is the little matter of the
potentially fatal gas mixing error George was talking about.

Bob,

The Iso valve is there for what its describes "Isolation", theres no
point in having it fully open as it acheives nothing. If you need to
isolate a cylinder and are losing gas then the quicker the better.
Remember when this happens every ounce counts. It can be confusing
only because the loss of gas is still happening from the failed system
half. The failed side should still be breathed till exhausted if one can.
Then hop onto what should be 50% of what you had when the failure
occured. The iso should be just cracked open to allow equalisation and shut
with the minimum of effort, come on think about this and get your head out
of the rubbish the agencies print. It is not common sense to have the iso
valve
fully open. Common sense is being familiar with the on/off directions of
all valves
and your buddies valves as well.
