There are quite a few applications out there. Most of them involve putting the mount on the middle of your yak, usually toward the front. DannyV (MSGDan) feels differently. He doesn't want to camera mount to be in his way when he's fighting a big fish, so he got a little creative. He used the conduit piping that a lot of electricians use. Although it's metal, it's galvanized and it has lasted him well.

I met up on the beach with him after a paddle in the Spring, and he let me take these pics to help others. Very nice of ya, Dan, and thanks!
