Unfortunately yes, I just sent it back for service
as it is what Delta P wrote me to do. Not too bad as I want to get the VPM algorythm put in anyway.
Thing is I still find it hard to believe that the depth sensor screwed up just on the very same dive I enter the water in DEMO mode, let s see what Delta P replie me when they get the unit.
By the way, it is not a metre or two, it usually reads 54 metres too deep
