This was contour footie from way back in like April maybe... The Countour has basically been a piece of shit for me on a mountain bike I think it just jars it too much and the battery goes loose and it turns off. Didn't have much luck with the gopro, either... helmet was too shaky and despite a few different attempts I couldn't dial in the right perspective/angle on the chest strap and all the footage is just staring down at the top-tube or my crotch or the handlebars.
Well, let's see.... we just used ours for zipling. Rigged up a mount on our shoe and helmet and it worked great. We have made a waterski handle and put it on the handle and that worked great. We have used the surfboard suction cup and that has worked. We put it on the paddle while paddleboarding also. Used on our motorcycle, on the car for autocrossing. On the kayak. And most of all snowboarding! We have many videos on our channel. Used it for hiking also. I'm sure there's more than I just can't remember off hand! We have 3 go pros so we try to capture things from all angles.
