I have had various suunto computers for ages and currently use two Helo2 computers. I have read several times in the past about problems with the sensors and about a product recall in the states, but never had an issue in the past. I am currently on a club trip to Normandy in France and after our second dive a low battery warning came up on one of my computers. Not to worry, I thought, as I have an official battery replacement kit. Sadly though, after a clean and dry off, and a change of battery, it now thinks I am at 25m while on the surface. I didn't buy the computer new in the states so I don't believe the product recall applies. Is there a fix I can do myself? If not, can/will suunto fix it? Or is it a bin job.
