Hey, is this thing on? Contour’s latest HD video cameras—the +2 (shown, $399) and ROAM2 ($199)—have large, glove-friendly, top-of-camera instant-on switches that take the guesswork out of recording on-bike action. Plus, with the +2’s built-in Bluetooth, you can turn your Android or iOS device into a wireless viewfinder to easily configure camera settings in real time and preview your shot before you record. The +2 is also equipped with a GPS receiver to track elevation, distance and speed, and has live HDMI streaming capability. Both cameras come with a wide-angle, 170-degree rotating lens, convenient laser sighting, a 4GB MicroSD memory card (expandable to 32GB) and a waterproof case that allows full access to all of the camera’s features.
