I need to go look at that data some more.... didn't catch a difference from the Petrel and Desktop, but wasn't looking for it......

My Petrel is in surface mode now as I am 10 days after my last dive. It shows max depth 42m and average depth 21m, so it seems to me that it is not weighted average but just max depth divided by 2.
Conservatism
The decompression model conservatism can be set to three fixed levels:
•
Low (45/95)
•
Med (40/85)
•
High (35/75)
The corresponding gradient factors are shown for
reference, but cannot be edited directly.
Low conservatism means longer NDL times and less
decompression. High conservatism means shorter NDL
times and more decompression.
The Low setting is similar to PADI and NOAA no-stop time
tables for air and nitrox diving.
Safety Stop
The Safety Stop setting can be set to the following values:
•
Off
•
3 minutes
•
4 minutes
•
5 minutes
•
Adapt
When using the Adapt setting, a 3 minute safety stop will
be used, unless the dive exceeds 100ft (30m) or the NDL
falls below 5 minutes, in which case a 5 minute safety stop
is used.
Hello,
Can someone explain me how is the average depth calculated on Petrel?
btw. Do you plan to include list of mandatory deco stops in new Petrel firmware? It would be nice to see complete list of all deco stops and not just the first deco stop.
I guess there is no chance to add a feature to ON/OFF deep stops in the future?
During a dive, if you run the Dive Planner in the Dive Setup menu, you will see a list of all future stops based on the current conditions.
but strange is that average depth is diffrent on Petrel and Shearwater desktop.
Cool, learn something new every day.
You really should know exactly what stops you are going to make before you even begin a decompression dive, and ideally, they should be written on your fins...
