Its a great idea and if you can figure something out, let me know! I tried all year to get a kill on film by myself and it's a total pain in the arse. On really super quiet mornings where I was late getting to my stand I never wanted to deal with getting the arm/camera all set up in fear of spooking deer. Example: the morning I killed my 130". Other times I got it all set up and pointed in the direction I "though" the deer were going to come from, then they show up on the other trail and in my hurry to get prepared for the shot, I don't have time to move the camera to get it on film. Example: the doe I shot on opening day, and the buck I shot yesterday. Other times it was just too dark to get anything on film. Example: the doe I shot in WI, and the coyote I whacked here in IL.
I have come to the conclusion that trying to film your own hunts is a total pain in the butt, and I need a cameraman next year. Or a big ol' pile of corn. That usually works pretty well too.
