I need some advice on my i470TC.
I've had the computer for about 4 years, and it's in very good condition. However, on my last two dive trips, I experienced a weird error. After the first time, I assumed it was user error. However, when the error was reoccurred in the exact same conditions the following dive trip, I'm now fairly convinced it's my computer's error.
TL;DR: I went for a night dive in the Philippines. Standard 4 dive day, all well within a safe range. About 2-3 minutes after entry, I noticed my watch was incorrectly in gauge mode. Given that there was no gauge, the computer calculation assumed that we were at something like 300 feet (we were at ~15-20 feet the entire dive). Unsurprisingly, my computer locked me out when I came back to the surface without completing the recommended 12 hour deco stop.
After this happened the first time, I assumed that when I was updating the nitrox %, I fumbled the buttons and accidentally turned on gauge mode. Since that experience, I'm very careful when updating the nitrox and always return to the home screen so there was no chance of buttons getting bumped on accident.
However, most recently in Indonesia, the exact same error occurred. Oddly enough, it was in the same situation - a shallow night dive after several day dives. I was extremely careful about programming the nitrox and kept the computer on my wrist the entire time, so I am fully confident that there were no accidental bumps to trigger gauge mode.
I'm left concluding there is something flawed with my dive computer, but am stumped on what. Any thoughts? Any advice on dealing with AL?
