I got a Go Pro Hero 2 camera for Christmas and found that the surf board mount that comes with it doesn't eliminate the wash from the board. I decided to make my own 1.5ft extension mount out of electrical conduit that clips into an FCS plug at the back of the board and it made the camera work better.
To check out how to make your own, have a look at https://www.youtube.com/watch?v=_vyxG1seTMI . The end of the film shows us having a surf with the mount on the board.
Interested in knowing what you think both about the mount and the GoPro camera.
I love mine. The quality of the image for the size and price of the camera is awesome.
