The attention-grabbing motion created by our Northern Flight rotating spinning-wing system results in more birds honing in on, and committing to, your decoy spread. A powerful 12-volt motor rotates two of your favorite spinning-wing decoys in an 8-ft.-diam. circle to create the lifelike appearance of birds funneling into your spread. Simply harness your decoys in, secure them with the adjustable Vortex Stand and watch as the ducks fly in for a closer look. Steel construction permits season after season of use in the most extreme elements. Battery and decoys sold separately. (Deep-cycle battery recommended). Imported.
