My dad just bought a used computer off ebay, got a fairly decent deal, anyway he brought it to a local dive shop and when my dad asked them to check/service it the guy pops it out of the console and imediatly says that the battery was changed 2 months ago and it's good, then doesn't want to do anything else. My father finally talks him into pressure testing it for depth acuracy.
Is there anything else to look for?
