What's your PO2?

[Dr Wu]

Strange distinction. Don't you trust your buoyancy control?

You never know when you are going to drop your donut.

That's a bit higher than the norm. Is this based on agency/training recommendations or personal risk assessment?

The latter. No agency would be dumb enough to put their name to it, if only for liability reasons. It's pushing it, but I know enough people who have done it that I'm not too uncomfortable, given my personal considerations. I'll give 2.31 a go some time, but probably just for one dive

What kind of exposure time to you plan for with a 2.0 PO2?

 

[Tortuga68]

Very short ones

So, if my calculations are correct, that would be EAN40 to 165'fsw? (On the fly, so might be wrong. ) Is a PPO₂ of 2.0 something you do often?

sounds like a dive you might be able to only pull off once

2.0 scootering trimix, 1.6 swimming trimix, 2.0 deco. I've never heard the Wah Wah's. But my lovely bride, OTOH, hears them anytime over 1.2, so I mix gas for the both of us for a 1.2, and we deco together.

 

[PfcAJ]

I just don't see the point of pushing something like ppo2.

Thanks, Wookie -- will you help a newb understand why, or the reasoning behind, going that high?

I've read enough history to know the early divers went that high . . .

 

[Tortuga68]

I just don't see the point of taking PP02 as the single, defining measure of a dive without taking exposure into consideration
