Product Description

The Back-Bone Ribcage AIR modification kit allows users to convert their own GoPro Hero4 Black or Silver into an interchangeable lens camera capable of accepting almost any lens.  N.B. If you are not confident about converting your camera SeeSense also offer a modification service.
