Gopro mount problem

I found an aluminum strap mount on eBay for the gopro . I just loop it thru the first strap on my dogs bay vest and the same on my catch dogs , where it sits right on top of their back , it's good if your running vest on your bay dogs. I get plenty of great footage this way ! As far as keeping them tight, I just take a Phillips screw driver and tight the crap out of the screw in the knob , it's very thick where I hunt and the gopro a always get slapped with tree branches , briars , barbed wire ect. And I never have had a problem yet with running them like this . You would be suprised on how right you can get that screw on the mount without it breaking !
