What's your PO2?

[Jax]

. . . You could only do this by gas switching on OC.

I dont know anyone that has a computer where they are adjusting the algorithm underwater by entering m-values.

Nothing underwater, Chris; the Sol tracks three bottles and their associated EAN mix.

I'm still using 1.6 as long as the workload is light.

On CCR I follow the ANDI recomendation of 1.3 on bottom.

The ANDI recomendation for OC is a max. of 1.45 for the dive and 1.6 for your bailout/deco cylinder.

Bottom gas PPO2 of 1.5 where there is a physical bottom (floor) for that depth
Bottom gas PPO2 of 1.4 where there is not a physical bottom (floor) for the MOD of the dive

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

 

[Cave Diver]

2.0 for bottom

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

 

[Cave Diver]

Oooops! I just realized I never put mine in. :blush:

OC - recreational and light tech 1.4 working 1.6 deco

OC - deeper tech 1.2 planned, 1.4 max for contingency 1.6 deco

CCR - short duration (< 2 hours) 1.2 working, 1.6 deco, 1.4-1.6 bottom bailout.

CCR - long duration (2+ hours) 1.0 working, 1.6 deco, 1.4-1.6 bottom bailout.

Even though OxTox has been observed at 0.5ATA, so its not watertight.

Do you have a reference for that Chris. I had not heard about a tox event below 1.2 before

I have heard of at least one incident of tox occurring in the 1.0-1.2 range and I *think* there was a discussion Thal was involved in that mentioned once incident significantly lower. I'll ask him to chime in if he recalls.

 

[cruiser]

OC - 1.2

I don't have tech training and do recreational diving only so far.

So it sounds like everyone keeps to the NOAA recommendations as a minimum, but lowers the PPO₂ for working, current, and/or time. Deco seems to be kept the same?
