Oceanic DSAT or PZ+ on backup computer

[tursiops]

Because of dives like this. OSTC clears when the red ceiling went away. Oceanic didn't clear until 3m, almost twice as many stops.

Up until a certain point, it's more conservative by a couple of minutes, so I was quite surprised.

And the Oceanic was set on PZ+, not DSAT? No added conservatism? What was the OSTC set on?

Yup, PZ+, no conservatism factor, safety stop off, deep stops off vs 30/90 on the OSTC. I expect it to be a bit more conservative than 90, which is normally fine because I do 5 mins from 6m to the surface, but this was surprising.

First thing I thought was that I'd put it into DSAT by mistake, but no.
