I have a Gekko Suunto dive computer that activates when I hit the water, but does not go into dive mode when upon decent. I tried going manually into dive mode, but it doesn't register any depth. I tried replacing the battery although the old battery registered fine. I took a look at the contacts and they are all clean, unblocked, and corrosion free. Any guesses? Do any have any experience dealing with Gekko and their repair services?
