Was diving a popular inland commercial dive site yesterday evening with my significant other who was on open circuit. We were just returning to the shore when we became separated. I was at 6-8m. Did a 360 to look for her (she was above me on the surface). Then another, so also headed for the surface. Met topside and it wasn't until I stuck my head back in the water to surface swim back to shore that I heard the alarms on my Oxyguages going off. There was 17% O2 in the loop. I'd kepth my mouthpiece in all the time.
Basically during the last few minutes I'd been concerned with other things and had not monitored my ppO2 during search and ascent.
No noticable ill effects. But...

Easily done mate (too easily!)
On an 80m dive I was busy and not really keeping an eye on the HUD or checking my handset enough. As luck would have it my unit decided to switch itself off. Luckily I was at 80m at the time and not ascending. I didn't notice the HUD light go out. When I did I immediately gave a little squirt of O2 and then checked the secondary. Fortunately as I was at const. depth it hadn't dropped much and it was still over 1.0. I switched the unit back on and it seemed ok.
However - being the twit that I am I didn't learn from this and at the end of the dive as I was ascending up the side of the wreck to the upline there was a short time that the unit switched off again. When I realized I checked the display and it was 0.7ish.
Obviously nowhere near life threatening - but it did mess up my deco schedule somewhat and brought home the dangers of not monitoring enough especially on ascents.
I think it was a good wake up call. I was getting complacent with the frequency of checking my handset/hud. (I find I have to still make a conscious effort to 'look' at the hud, even though its in view all the time)
The reason the unit kept switching off was the magnet on the on/off reed switch was corroded and it was loosing contact.
