What if you need to use some of that 500 psi contigency reserve?

Well you don't feel like a god when someone comes at you with there eyes wide and screaming in the water! Have you ever seen someone drown? Well I have! If I were god buddy it wouldn't have happened at all, but CPR does work and don't give up!

Ahhhh...to be in the presence of the one true dive god.

I say...Hallelujah

I only saw Papa_Bear's last two posts after I had typed mine. I wish I had seen them before posting, so that instead of questioning his wisdom, I could have knelt down in worship and praised his mighty, everything surpassing dive knowledge.

Well this thread took an even uglier turn than the one I was composing. After putting 15 minutes into it I will still post. Please note I am not recommending this exercise when PB is your buddie! :no

I ended up with 200 when I hit the current line. I won't breathe the tank any lower unless I am in distress because I don't want to chance getting water in the tank.

I suggest everybody consider taking a tank that needs visual inspection into shallow water (10') and breath it down until the reg does not give you a full breath. By all means be safe, wear a full tank and hold that reg for safety. There are three things I learned by doing this; What my gauge reads when I can't get a full breath (at 10'), what my reg feels like when I drop below the normal delivery pressure (at 10') and that no matter how long I sucked on the tank I still had enough tank pressure to dry an Aqualung dust (water) cap. Also, if the last air in your tank goes into your BC (at the surface), the pressure in the tank is equal to the pressure in your BC, so the tank is not really empty, it just can't put any more air into the BC.

IMHO, you would have to take the first stage off, open the tank until it makes no air escaping noise (actually empty)and then submerge the open tank to get water in it. Perhaps this would be a good question to ask Myth Busters!

It is most certainly the anti GI3.

Have you ever seen someone drown?

Actually, I have. (Wasn't a diving accident though.)

And when you have a 1000 dives speak up Mr. 100 to 199 been diving a year! Glad your getting entertained I hope you get educated!

Ease up brother. I ain't looking for no trouble.

I have sucked every drop out of a 72! Sucked it negative and if you open the reg it will pull water into it! In the 72cft J valve days sometimes they got pulled down in kelp! I have run out at 60ft! Panic kills not out of air! A little more at the knee please!

That's what I'm talking about for Myth Busters!!

Cool, but I will not be following your gas management plan.
