Kickstarter project which replaces the front lens cover for one with a clip that you can use with supplied steel tethers to attach your camera securely to back up your existing mountbor just for transportation. Check it out, only one week left to back this project! Price point is really great too in my opinion! http://www.kickstarter.com/projects/1833528339/hero-3-tether-never-loose-your-gopro-camera
Yeah you could blow $25 on that, or you could just tie some high tensile fishing line through the mounting holes on the bottom of the camera. That big black strap right next to the camera lens will definitely be in the way of most shots, especially in wide mode.
