I hear you. I haven't had the ccr for that long and I kinda lost trust in SW's reliability now since this has happened so early on. I didn't even take any beating in a cave yet. It crapped out after a shore dive.
I see that I'll need a spare handset if I don't wanna risk being on BBQ duty all day every day on the next dive trip, but at this point I don't really wanna give them another 2 grand for a fourth computer that may or may not last a 100 dives... I'm seriously considering dumping the DiveCan for an mCCR.
