Rebreather World - View Single Post - What setpoint for 100m+ diving do you use?

I use a 1.3, but bump up to a 1.4 up to 20 feet where I always do an O2 flush. I am usually over my CNS on long dives (anything over 2.5 hours). On the bottom, it would likely be better to run a lower setpoint (like 1.1), but I have it in my head that every minute at a higher PO2 is less gas that I absorb. I also usually run my offboard deco at 0.1 lower than my actual to add a bit of conservatism on the deco side.

Aloha,
Charlie
