Subject: bottle markings
Anthony, you had it dead right and then regressed with the "tactile"
bullshit in your last paragraph. The answer you are missing is as
follows: 1) do not expose yorself in open water to a decompression
obligation where you could not just keep breathing the known gas to get
out ( fear of deco), 2) in a cave the bottle is not taken past its
depth, 3) there is no way to identify other than looking at the depth
which is painted on the bottle ( assuming you followed our gs mixing
guidelines). As you said, if you can't see that, you can't see how deep
you are anyway. 

 The guy you were discussing this with is an obvious stroke, and your
points were perfect. That is one way that many people get killed gas
diving - breathing the wrong gas .

 Only the worst moron would mark regs or use other "systems" to identify
gas. Try any of those assinine tricks with three guns: load one and
leave two empty. Put different colored tape on them and put them in
holsters on differnt sides of your body. Then take the empty ones out,
hlld them to your head and pull the trigger. Should be no problem
remembering which one is loaded, and if you are not sure, just look at
the tape.

 The way I would do it is to leave the breach open, which is the
equivalent of the WKPP bottle handing guidelines: with our method, which
has been discussed extensively and is on our webpage WKPP.org, if you
can breath , you are breathing the right gas.

 What is being taught out there is a real shame, but then it is being
taught by people who do not really do it .
