I want to use a rod handle as a base to keep it from wobbling in the rod holder. I found that if it doesn't lock in place you can get a constant rocking and if you try to point the camera sideways, gravity turns it back to point at the stern.
Also, I want it to be able to float a camera plus any "backpack" accessory.
I've thought of a new "cheapo" camera to get different angles at the same time, maybe someday...
I have used my old Fuji pocket camera that is waterproof and shoots 640 HD
Maybe send one down to the wrecks this coming season
