I have 2 or 3 weasel balls that I use as decoys. The oldest one is worn and has become a little noisey. All I do is paint the ball black or brown, drill a small hole in the top half of the ball to attaach a peice of black nylon string with a fishing swivel. I usually cut the string about 6" long. Then I hang the weasel ball from a tree limb, fence, old arrow shaft, etc., over the foxpro caller. It moves just enough that the coyote dials in on it. I have killed several coyotes using it. Cheap decoy. Where I hunt there is always a tree or fence to use. Killed one last year that came in upwind of me and was standing 14 yds. from me staring at the weasel ball. she was so focused on the weasel she had not clue I was there.
