Deko time at 6m countdown is much longer than shown

[mobln89]

Hello,

I have a problem with my ostc3
There is shown a deco time for example 10 min at 6m
But it takes around 18-20min to count these 10min down.
To reduce 1min of deco needs Aerojet 1:30-2min realtime.

Does someone knows why this is or has any idea how I can fix this problem?

Thank you very much

Hello,

Can you post your Gaslist for this dive (As shown in the logbook)?

I don’t know how to upload a picture

German
OC Gas List
Luft * 56m
Nx50 = 21m
Luft X 56m
Luft X 56m
Luft X 56m

I did not use the nx50 (I just had it with me)

Then you need to disable the deco gas (You can do this during the dive, too). The OSTC assumed you would be changing to this gas (Which would have accelerated your deco). That resulted in the discrepancy you saw.
