| It was the lack of O2 in the 10/52 mix I was wondering more about as that reduces the options for using it as a semi closed gas.
You are also using quite a low ppO2 on the 17/30 as you are only going onto it at 50m. I had assumed as the pp02 of the 17/30 was 1.36 at 70m that you would be using that gas alot deeper than you are.
Are there any particular reasons for using such low ppO2 values? Do you run with a lower than 1.3 setpoint for the bottom segment of the dive?
I hadnt really looked at the ppN side of things it was just the low PP02's that had caught my eye.
Yes I was expecting there to be 50% and 100% available between the pair of divers for the shallower water deco. |
