I have quite a bit of video up on YouTube.
http://www.youtube.com/my_videos?feature=mhum captured with the Playsport I am using a mount that Mike Hopkins developed. He can be contacted at
http://www.forhuntersbyhunters.blogspot.com/ He is always working on different mounts.
You may find that the camera mounted on the 1/4-20 adapter is unstable when the arrow is released.
Good luck hunting and please go to
