You know what one of the many camera companies need to do is separate the lens from everything else.
I'm considering the Liquid Image goggle cam becuase they don't have the camera sticking out there to get damaged. As hideous as many say the goggles are, I'll take the trade off of functionality.
I might F up a regular helmet cam wiping out, or beat the crap out of it unexpectedly getting into an area where tree brances can smack it.
Same thing if I were still dirt biking.
Separate the camera; it's smaller and less protrusive. Have a length of wires that can be ran down to my inside pocket in my jacket where the battery and everything else can be.
Just a thought. And if you use it, I WANT A CAM FOR FREE!
