What ppO2 do you use and why?

[syntaxerrorsix]

Max 1.4 working and max 1.6 resting.

1.4 ata and I rarely hit that. Most commonly diving with 32% (MOD 33 metres) and rarely even get to 30 metres when I'm diving unless I have a reason to do so. I am aware there are different schools of thought on the 1.4 / 1.6 / 2.0 debate but since a lot of clever people have done a lot more research into the whole thing than I have, I'll stick with the conservative limit all the same.

 

[Dive Bug Bit Me]

Working I will peak at 1.4 ppO2. Most of the dive is below that.

Deco I will peak at 1.6 ppO2 and try minimise time at this level. If conditions allow, I will move my six meter stop to a level between 3 and 5 meters as soon as my deco algorithm allows.

I have done a quick bounce to 1.8 for less than a minute to assist a buddy.

Very few people have survived an oxtox attack in the ocean, so I respect oxygen.

1.2 during dive, 1.6 for deco.

 

[Tigerman]

I use 1.4 with 1.6 contingency. I know from experience im OK with 1.4 but I USUALLY dont go above 1.3 due to using mainly 32% and single tanks.

I use 1.6 as my limit. I exercise increased caution above 1.4 - short exposure times and low levels of effort.

 

[Garth]

I dive 1.2 throughout the dive on my hammerhead as my diving doesn't require anything lower. If I was diving open circuit I would dive 1.4 max for bottom gas and 1.6 for decompression.

 

[Scared Silly]

1.2 working, 1.4 when need and deco, 1.6 deco.

Just a reasonable amount of conservatism when doing technical dives.

 

[uncfnp]

I have a slightly higher than average risk for undeserved DCS so I set my computer for 1.5 and when able dive Nitrox 36. In practice, I have never exceeded 1.4.
