True Lamont but I don't see the point, just for fun I guess.
lamont:
That would be a safer alternative, but will still require a visual.
You should laways assume a possibility of gauge error up to 300 psi. Beyond that if you calc. your rock bottom and dive your plan assuming you had a gas plan an ooa situation is less likely. If you dont know how to figure your sac rate, rock bottom and make a gas plan maybe you should not be diving so deep.

techdivers around here do this routinely and don't run out and get a VIP right afterwards...
if you hit your purge after you breathe it down you might get saltwater in the LP hose back to the first stage, but it shouldn't get into the tank...

What are they practicing Lamont?
lamont:
I doubt that they are getting fills at the LDS. It's not optional if you bring it to a shop for a fill. Even if it was someone I know and like, I'd want to pop the valve and have a look.

well:
- that's just how they use them as stages, they drain an Al80 dry and then go onto backgas or onto another Al80 stage.
- they're typically diving with the LDS owner
- we all pump our own gas

I've dived a few times, not that many compared to many here but more than my next door neighbor. It would've surprised me if I had run out of air, a lot, big surprise. I think you did great Pietfer..........you're alive.

I had no idea they breathed them down to 0.
