MOJO has develop motion originally intended for a goose decoy spread, with the development of their patent pending MOJO Mini Flags, which are small flags fashioned after the large flags typically used for attracting geese at long distances, and rotated by a motorized housing that can be scattered thru the decoys to give the impression that the decoy spread itself is moving. It has been field tested and proven very effective. The decoy is furnished in a 4-pack with each having different on/off timing to simulate real life-like movement. Comes with 4 dark and 4 white flags. Operates over 12 hours on 4 AA batteries.
