Re: [PSUBS-MAILIST] Stupid Idea was Burst Valve



I agree that the Burst valve isn't a good idea, which could end up killing
people.

The flood valve (AKA scuttle valve) is NO JOKE and is going to save lifes.
That is unless you're spending so much time and money that you would prefer
to die rather than get your sub wet and live.  Of course this is the VERY
VERY LAST OPTION (well second last if you count dying as an option). You'd
have to be a fool not spend the few $$ on way out of your sub in an
emergency.

For those who choose to death over a flood valve, make sure you have
enough CO2 absober to out last your O2 supply, otherwise it's going to
end with a very painful headache.
