Subject: Re: Co2 Cartridges
WW,

Read my post.  I said your FIRST stage.  You're on a single 80 - your first
stage takes a dump (I saw this happen to John in Fiji - luckily we were on
our way up, and had two stage bottles with regs handy).

If your second stage takes a dump, who cares?  You switch to your backup and
la-de-daa...  But when the burst disc goes out on the first stage - your air
is in the water real fast.

Considering my scenario, you are still screwed, even if you drop your belt,
tank, etc, and swim for the surface.  You have no air, you are sucking your
lips (as John so aptly put it) and you are wearing your neutrally buoyant
lycra suit, so you have NOTHING but your own ability to remain conscious with
a dwindling O2 supply in your blood (remember "shallow-water blackout?).  

If you go out - you would probably sink, and therefore die.  Bummer.  But if
you had an emergency inflation device, maybe you would have a better chance
of making it to surface air.  That is all the question is about.

I'm not advocating carrying CO2 cartridges strapped to the BC - I'm just
arguing that John's question was a fair one, and that it deserved a little
consideration from this list.  Not many people have gone to the places he has
gone, nor have many done the level of diving that he has.  If this was some
weenie asking the question, I could undestand the flames.  But John is
definately no weenie.  Even though I accuse him of that sometimes.

Don't waste our time telling us how "we shouldn't be in those situations"
unless you dive with us, and understand the situations we encounter on our
dives.  Many a "technical" diver has lost it underwater, and to simply state
"well, he fucked up" is to denigrate valuable lessons that we all can still
learn in this sport/profession.

enough said.

Kevin.
