I realized that is designed for a "GoPro" this belt, but since the guide rails looked reasonably fit in the picture, I have thought that I just 'times should risk the 4.86 Euro (incl. Shipping).
After just over 3 weeks, the part of China trickled into my room and I went immediately to it, with my "Dremel" multitool and a file to edit the guide rails for the camera attachment, ... slowly, concentrated and piece by piece.
So after an hour I was able to "Denver" Attach -Halterung on the "GoPro" chest strap, ... unfortunately then it occurred to me that would not engage the two locking lugs of the bracket, as the lead for a bit is too wide. ..andererseits the locking screw of the mounting clamps laterally exactly on the buckle of the chest strap and secures the holder against slipping down.
Have not tried it all, but if it is not enough to secure the camera reliably, I'm from the bottom screw on a backup disk, so that contrast pushes the holder and can not slip out of the guide rails.
Well, I think, for 4,86 Euro my experiment is very good and I have a part of what it is less important for the "Denver" camera .... and even not so unbeatable!
