In other hunting locales a snow goose is a natural sight, and it sure will get the attention of real ducks and geese from long range. But it's ruggedly made. Outlaw Decoys doesn't make a self-activated decoy. It's made from actual photographs on life-size silhouettes of snow and Canada geese. Once the spring is wound, the wings turn in the opposite direction.
Hunters learn to pull the string and activate decoy wings when needed, as when birds fly overhead.
Essentially a heavy anchor is set in the decoy spread, with a line running from it to a decoy or two, then to hunters in a blind. They make full-body duck and goose Wave Makers that wiggle and wobble, putting out waves exactly like real ducks. It has a counter-balance weight that causes the decoy to wobble and simulate feeding. Powered by a battery, the prop pushes the decoy in circles. This is one deke that better be anchored well, or it'll literally swim away.
