    My son and I both were both diving with our Mares Puck Pro Plus computers yesterday and something odd happened. After we surfaced from our dive (55 minutes, max depth 63 feet, average depth 47 feet, on 21% air), both of our computers were in 24 hour Desat and Bottom Timer mode, and the bar graph at the bottom showed our Nitrogen maxed out. However, I don't believe we went into Deco, and we did the normal 3 minute safety stop as shown on the Puck, and the Log entry for the dive states "No Deco", which if it were a Deco dive the Log would show "Deco". Even 6 hours after our dive the Nitrogen bar graph was still showing maxed out. Both computers are set to P-0 (least conservative) setting.

    This was in a quarry we've been in a good bit, and have had similar dives with nothing like this happening. We double checked the dive tables, and it didn't seem to make sense that we'd be locked in Desat. We thought about doing a 2nd dive using tables, but decided to err on the side of caution and follow our computers and not do our 2nd dive.

    Is this a glitch in the software?
