Had the Paralenz for about 6 months now. It's a bit hit & miss though and resets it's settings randomly. As there's no monitor, it's hard to tell by looking at it.
Anyway, I managed a dive in Loch Ness (dark, featureless, little life, more like cave diving). I was filming using the Paralenz for most of it, but the videos (1080p @ 30fps) seem to be running at twice the speed. Slowing them down in VLC to half speed seems to be about the right speed, but now rather jerky.
The other videos from the rest of the week don't seem to be like that.
