Don't use a go pro for filming the animal. Have a camera arm with a real camera on it. Make sure you have a liquid head so that the movement of the camera is smooth and quiet. Muddy makes some great arms for mounting on the trees. I use a tactacam that is pointed back at me on my bow for drawing purposes only. Search on youtube Outdoor Product Review and I have a few hunts on there along with all my reviews. I have my daughters mule deer, sons first whitetail, and I have a hog and turkey hunt too. Shot the turkey at 50 yards with my boy on a TV show.
