How deep on air?

We learned that the high set ppint shoudl be no more than 1.3 bars, an the low is .7

Over repetitive dives some guys have had vision issues at high setpoints.

Can't use a set point on OC but you can get out of the water a lot quicker than CCR.

Hi set point of 1.3 is to counteract the spike after an O2 inject, most CCR users I know run 1.6 on ascent.

I am always presuming we are talking CCR diving. 1.3 is the standard CCR high setpoint P02 but I am sure there are guys who deviate from that.

At a P02 of 1.6 one is going to be getting constant 02 injection from 20 feet and shallower so we always switch to the low setpoint above 40 or so feet.

1.3 is the standard as set, it can be changed. I lower it for really long dives i.e. >2.5 hours.

I leave the set point at 1.3 until I finish my 3m (10ft) stop and manually add O2 to get to 1.6.
