Recently bought a GoPro Hero 5 Black. I specifically bought it for hiking and fly fishing. One of my major concerns was losing the screw device used to fasten the camera to the mounts. While looking for a back-up, I found a complete set of replacement mounts, that included the original mounts and screw devices, but added additional mounts and styles of screw devices, for what I felt was a minimal price. One of the mounts fits my chest harness, but mounts it slightly further away from the harness attachment With the standard mount, video showed the ground from about 20' out, unless I leaned forward. This additional mount allows me to tip the camera downward to pick up the ground at about 6' away and easily covers everything I want to see. Double score.
