Very good points you make Adam.  However, I think they are many situtations
that a scuttle valve might allow me to escape with my life.  Maybe I'll be able to
come back and get the sub, maybe not.  But I'll take a $25k hit the wallet to keep
my life.

I hate to always sound morbid and maybe negative, but make sure the CO2
absorber on your sub will out last the O2 supply.

Lets say that whatever it is your stuck to is restricting your hatch from
opening, then what are you going to do? Lets say there is a black hole in
that lake in your backyard, lets say that sea monster was a lot bigger then
reported!

We have all been there with something or other, where we thought the best
thing to do was to break the window to get back in the house or car, or
gotten off the trail thinking camp was that way, or damaged something or
other and only in hindsight seen that I didn't have to do it that way!

Why inflict permanent damage on your sub and possibly yourself, and at the
same time leave a years wages at the bottom of the ocean.

Look at the sub incidents in the past.
