Setpoint value

[BlueTrin]

It seems most people I know use either 1.2 or 1.3 for high setpoint.

How do people decide what is the right setpoint, is that mostly a concern for longer deeper dives than MOD1 (and repeated dives)?

Usually I run 1.2 at bottom and 1.3 at deco for dives up to 3 hours. For longer dives I lower my bottom po2 to 1.0.

Sounds like good advice to me. Although I may get the PO2 up higher at deco, sometimes I switch to an OC 100% O2 bottle to complete the deco.

Same for me also. But like @Capt Jim Wyatt said I usually run a higher deco SP. I like 1.4 and then depending on the dive, CNS loading, how much deco I have ill do o2 flush at 6m and finish deco on around 1.5‘ish

But yes for longer 3+hr dives or deeper sub 120m I like to run 1.0 SP

I just based it on the dive time in a 24h period

Max time [hh:mm]	-	12h	12h	9h30m	7h30m	6h	5h	4h30m	4h	3h30m	3h	3h	2h30m
pO2 set point [bar]	0.4	0.5	0.6	0.7	0.8	0.9	1.0	1.1	1.2	1.3	1.4	1.5	1.6

When you run it at 1.3, do you just run it manually at 1.3 during deco with the setpoint at 1.2z

I note the correlation to the CNS max exposure. Do you maintain the same SP for deco, then?

I recently switched to 1.3.

During ascend, o2 flush at 6m, then run the highest possible setpoint until done.

Nope, these are my set points. For deco I fly manual a bit higher
