This is the home-assembled waterproof mini-cam rig we used to shoot some of the coaching sequences in Sea Kayak with Gordon Brown, Volume 1.
There's a lot in there. A Sony camcorder which works as a VTR.
A Sony mini-camera which we mounted on the end of the pole to give the big top shot.
And a cable microphone, which I added after the shoot and never actually used. Plus the Pelicase.
If you'd like to see how it was all rigged, then take a look at the video below.
