This is not the first Go Pro Underwater Camera, but while the previous models didn't really have enough pixels for it to be worth the bother, the newest version has 3 million - now we're talking! The camera attaches to your wrist so you can wear it and surf, and has a 3x sequence burst - essential for capturing action sports. The sample picture above shows what sort of image you could capture (although I can't guarantee you'll surf that well or have such nice waves) and the upgradeable memory means you won't run out of memory until your fingers have gone wrinkly.
