Gopro makes ok cameras. The problem I noticed is that the sound quality is junk and since the lense is concaved, everything appears to bend inward. I've seen a few youtube videos where hunters mounted the Gopro to their bows and the footage is good until the shot and the camera absorbs all the vibration and you never see the arrow impact. But, it looks like it would be good for second angle footage.
I only hunt on days that end in ' Y '.
