Thanks for posting, I was wondering.I use a GoMask. Had to add some extensions to make it work, but now it's great.
Here's last weeks dives.
And a thread on the camera.
Paralenz Dive Camera...
It doesn't seem to handle white balance well even though you were shallow (51' = 15m) Same as Go Pro
Answered that question for me. My old G16 I could white balance on the sand and get better colour. I was hoping that teh Paralenz would suit rather than a G16 replacement..
No comment about the numpty actions with the turtle from yoru buddy
