VPM-B difference OCTS and subsurface

[tdewilt2]

Hi

I have both the OSTC 4 and subsurface on VPM-B +2. if I look at my last dive (nx30) I see subsurface calculates a ceiling but the OSTC4 did not. can anyone explain this difference?

thx in advance,

Teun

Just to make sure, do you have "Draw dive computer reported ceiling red" selected on subsurface?
It's at preferences -> tech setup -> ceiling display setup

the computer ceiling is on in subsurface, during the dive I also had all the time more then 5 minutes NDL

Matthias Anny clue?

I don't know the answer but last dive I did, I was using Bühlmann ZH-L16 with GF low = 30 and GF High = 80 and had 2 mintues of Deco at 6m depth, switched to VPM +3 and it showed NDL = 50 minutes or something like that!!!!

I was very surprised, switched it back to Bülhmann to finish the dive but now I am very confused about using VPM
