Headed For Trouble

Helmet cams are the latest must-have gizmo for adrenaline junkies, who post their exploits online or e-mail clips to friends. They mount to headwear, handlebars, surfboard or kayak, leaving hands free for rip cords or ski poles. The POV.1 features a lipstick-size camera, a wireless remote, a microphone and editing software that allows users to organize and upload clips to video-sharing sites ($700; vio-pov.com). The Digital Hero 3 has waterproof housing, shoots 56 minutes of video and features a slide-show mode that takes a picture every five seconds ($140–$180; goprocamera.com). Built for simplicity, the VholdR features aluminum housing, one on-off switch, no cables and weighs 136 grams ($350; vholdr.com). Thrills and spills are for sharing.
