Rebreather World - View Single Post - PO2 Set-points (WHEN!)

**wedivebc** · 13th April 2008, 15:50

Thereare 2 stategies I use depending on the type of dive I am doing. For a dive with a gradual descent such as shore diving I change to high setpoint as soon as I reach 6m I also change back to low setpoint on ascent once I have cleared any deco I might have incurred.
For rapid descent such as boat diving on a wreck I descend as fast as my PO2 will allow me (it usually climbs as I descend) and switch to high setpoint when I reach max depth. I use the same ascent method as above.
I have had instructors who were evasive about answers and it turned out they wanted me to think for myself. Let's hope that is the case here.
