   Richard, I am currently in possession of one of these to see if it
will hold up. I don't like the idea of the long hose being
shut off, but I worry about losing any gas while on my stages.
While I have not lost any gas while riding, I though I would
try it, or maybe I won't.
      I leave all of my second stages loose
anyway, so I could take the thing off if it fails and just put
the second stage back on without it. I can change out all of
my second stages underwater, so if I am having a problem with
a main reg, I can swap it with a stage bottle so that my main
gear is still ok, and the thumb can stay in the pocket. It is
easy enough , as you know, to breath a stage bottle with a bad
second just by turning the valve off and on.
   I got this device from Deans who uses them for his downline
O2 to keep the regs from freeflowing. It appears, now that I have
thought this out, that I willnot use it on my main gear, but will
use it on deco bottles wreck diving so I can leave them on and
keep the salt water out of the first stages. Thanks for reminding me,
RT (about the o-rings), you are right. - G
