Not everyone can afford the latest GoPro camera. So please post what other options you are using for a helmet camera.
Contour Roam POV Camera review - Nice low profile camera fi you don't want a bulky camera with a playback screen. Priced around $150.00 I'd consider one. This camera was used by the TV show Dirty Jobs when they needed to go somewheres the regular cameras could not. And we all remember the nasty environments they used to film in.
