Abstract
A decoy rig 100 is described having a number of individual decoys 102 deployed at intervals along the length of a shaft 104. The decoys 102 are deployed at an angle relative to the shaft 104 axis, and oriented around the shaft 104 diameter similar to the blades of a turbine rotor in relation to a turbine shaft. When driven by natural forces the anchor 110 holds decoy rig 100 in place against water or air flow inducing a differential pressure across the decoys 102 providing the motive force to rotate the decoy rig 100. In operation, the decoy rig 100 floats centered at or near the water surface and is moved by external forces such as wind, water current or tide, or may be mechanically driven thus causing 360 degree revolution movement by the individual decoys 102, effectively simulating the diving and feeding action of the decoy's live counterparts.
