The Drift HD170 Stealth action camera is the most feature-rich hands-free video camera on the market. It offers innovative features that you can't find in other helmet cameras - like an LCD screen for lining up that perfect shot and an RF remote to turn the camera on and off while it's on your helmet or outside your vehicle. The Drift HD170 Stealth shoots professional quality HD video with features such as 4x zoom, night mode for optimal performance in low light conditions, 170 degree field of view to capture your peripheral vision, and the option to shoot buttery smooth slow motion video in 60 frames per second. The Drift HD170 Stealth's intuitive operation makes it easy to use. And your Drift HD170 Stealth includes multiple mounting options for helmet, goggle and handlebars that would cost $75 when purchased separately through other manufacturers.
