The waterproof HD video camera inside the goggles records everything you see, which makes it the ideal hands-free camera for recording hours of outdoors sports that require you to wear goggles. You can record entire skiing and snowmobiling expeditions. Wear them on a Motocross ATV ride or while jet skiing. It has both photo and video modes, and a microphone with a wind guard to reduce noise. The 4GB card holds two hours of video, and you can throw in a MicroSDHC card to hold another 32GB.
