I've studied the GoPro pretty closely, but have thus far not purchsed one. I've also concluded that it's not very well suited to capturing bow shots on game beyond very close ranges. What they seem to do extremely well is (of course) close-up video work, and I think they're darned good a capturing a pov (point of view) video during active pursuits. I'm talking about hiking, running, boating, swimming, fishing, surf play and just interacting with others. I'd love to have one while hunting in Alaska, as I think it would be great for videoing camp life, hiking/stalking, wading rivers, flying in the Super Cub, and maybe big animals up close such as moose or caribou. Conversely, I suspect I'd almost never use it for anything deer hunting, except possibly the recovery.
