I bought some cheap copy type thing and I have to admit, it takes good pics above and underwater once you get used to changing the settings before you go underwater. Cost me $250 and has video. Gets knocked around a lot. Uses standard aa batteries (apparently all good toys do???) and is waterproof to 10 meters. It is made by a canon or olympic or someone but marketed as a cheaper brand under a different banner. I bought it at Betta Electrical in Gladstone 2 years ago. Make sure you wash the salt off after every use or the buttons get a bit sticky. Its for a boat.......It needs to be cheap as it will get wet and bashed...
