I started diving again after a 2 month break, I work as a DM and I've used my garmin G1 without issues. Today, first dive after 2 months, my garmin doesn't start my dives. I took it diving (with my colleague, so I wasn't without computer) and the watch stayed on hone screen, I tried to start the dive mode manually but I was under the sea (up to 10 meters) and my watch didn't react at all.
I manually reset the altimeter, is there something else I can try? Does it need fixing? Reset?
