The WINDUK was created to be an addition to your existing traditional floating decoy spread. While in use, it gives your whole decoy spread more movement. Meaning, when ducks see the spinning wing action, they often come closer and more interested in your entire decoy set. We found the most effective set-up to be at least two WD in combination with traditional floater decoys. Last year I hunted a few stock tanks with only six to ten floater decoys and one WD. When fewer decoys are needed, the WD really comes through as an easy “set and forget” motion decoy. It is very lightweight and portable in even the worst Duck Hunting conditions. No batteries to charge or tote with all your hunting gear is another benefit.
