I purchased a wrist cam from the Eastern Sportsman Outdoor show this winter, that a local guy was peddaling. It holds your own video camera on it and fits around your wrist of your bow arm. I have practiced with it and plan to use it this fall. It makes your arm tire much quicker when holding the bow ,but it does give you the opportunity to point your bow or arm at the target and get video. Hunting from a tree stand should lessen the arm strain by pointing down at the target. I tried using a tree mount for my video camera last year and it did not work. I just hope a booner doen's walk by and I can't hold my bow up long enough!
