I have been doing a lot of OW teaching on OC recently and just duck-dived from 6m to 12m without thinking, and it was after this that the cell was over reading, so I wondered if I'd managed to get water on the face.
I discounted this though, as on the Kiss, any water seems to gather in the base of the scrubber, in my experience and so figured the the knife-saving manoeuvre would have just soaked the bottom of the s'lime.

There are always sizable water droplets from condensation on the face of the sensors in my O2ptima after a dive. They collect on the hydrophobic membrane on the front of the sensors. It doesn't seem to cause any problems. On multiday dives, if possible, I'll open the canister, remove & store the cartridge, and let the head dry a bit after the last dive, if conditions permit.

Salt water in there is a whole other issue, which would cause a host of problems.....

This was about a 40 minute dive, 35 up to the point of the duck dive, so condensation could be an issue, apart from the cell failing there were no other problems such as seawater ingress.

The scrubber had already had about 50 minutes use before the dive, but I had removed it between dives and it had dried out before the dive in question.
