Calling it a helmet cam doesn’t do this sharp-shooter justice: The waterproof GoPro HD Hero also mounts to a chest harness, handlebars, a surfboard—or just carry it in your hand, where it still captures 5-megapixel still images.
The 1080p HD video records at 30 frames per second and offers two wide-angle settings, 170 and 127 degrees (but no zoom). For best playback, pair with an HD TV or PC/Mac with a high speed processor and video card. $299; 6.3 oz. (including battery and housing); goprocamera.com
