Less wobble. More realism. Until now, all spinning-wing decoys have been designed incorrectly by attaching the motor, battery and other components to the inside of a hollow rigid body, which resulted in significant vibration, wobble and noise. But the MOJO® Mini Mallard Hen is designed as it should be. The motor, transmission, power supply and body are all attached to an easily accessible structural support frame. The outside of this housing fits precisely inside a flexible decoy skin, which features a "drop-in" battery housing. The new design results in a smoother, quieter Decoy. And a smoother, quieter Decoy means more downed birds.
