The upcoming VholdR's laser guided helmet cam looks extremely promising! It is cheap in terms of such gizmos ($350), simple, and looks very effective. I like my VIO POV.1 a lot, but encapsulating everything in the helmet unit is awesome, and the laser guides and lens tilt adjust are brilliant (this is always a pain when swapping my helmet cam to other people's helmets or what not). I look forward to seeing this when it comes out.
Anyone seen one of these in person?
