As a diver I already have a small video camera with a water proof housing
, and after reading this thread I will try and find a solid way of mounting the housing on the a frame, and also I can use a remote control (ir) to start and stop video as well as take static pictures.
Might make for some cool images/video.
PS A company called Ikelite make very good underwater housing, and as they are designed to go to depths of 60 metres, the housings are very strong and roboust. http://www.ikelite.com/
and they have distrubutors with stock all over the UK.
