I had an interesting experience with my Atmos ai in Cozumel last week. Apparently, the unit calibrates its pressure sensor upon power-up. The only problem is that it will not power down for 24 hours after a dive. When we would dive the next morning, my computer calibration seemed to have drifted and therefore it read -24 feet. This wasn't a big deal at the time - I just popped the battery out and then back in to force a recalibration. Aeris did a GREAT job in replacing it immediately. I'm just wondering if anyone else has seen this.
