I have an Oceanic ProPlus X with 106 dives on it. After charging it up for my last trip it displayed a red screen that said, "Error Calibration". I decided to see what it would do on a dive and it worked except it told me I was at 15 ft when I was at 32 so that's the calibration error. I wrote to Oceanic and they said they'd look at it for $30 and if it needed service that would be $260 (they credit the $30). I have no interest in ever using this computer again (bought an SPG and a Sheeawater Peregrin) but I honestly don't know what to do. I could get it serviced and sell it or it would be an expensive door stop. What would you do?
