@scubadada, that’s correct. The first one sent me into an O2 violation 15 minutes into a 25’ dive (3rd dive on the unit). The second wouldn’t shut off (2nd dive on the unit) but the third is doing great with about 15 dives on it. I’m also one using it as backup to a Geo. I’ve talked to too many people who love their i300 to think anything other than it was poor luck. Kinda like a Subaru my wife had that blew a gasket and cracked a head right after it came out of warranty. Too many people love them for us to not think we just got a lemon.
