This mount attaches to a GoPro fitting and onto a tripod mount, allowing you to easily add a GoPro camera or accessory onto another camera.  Or to attach a different action camera (such as Sony, etc.) to GoPro accessories.   When fitted to a GoPro mount such as QR mount, this adapter allows for easy tilting of the camera.  The tripod screw thread is a 1/4-2, fitting most small/compact cameras.
