Beautiful OnesAction camcorders have been around for a few years, and the market is led by Contour's rival, GoPro. But the ContourRoam HD Camcorder offers some clever design touches that make it a terrific entry-level video camera for action sports. First, it's waterproof, so you don't need a protective case when you hit the slopes or ride the waves. Second, its power switch is a beefy toggle on top of the barrel-like device, which is a real bonus when you've mounted the camera on a ski helmet. And the gadget includes the Contour Storyteller video-editing and organizing software, which makes it a snap to share footage on social networks.
