I was provided a decoy motion system called the Duck Thang for use during a Wounded Warrior hunt that I hosted in Ballard County, KY and all I can say is WOW, what a great piece of equipment. Its nothing like the Duck Commander Wavemaker, which moves decoys back and forth. This one moves your decoys in a continuous motion in the shape of however you place the idler pulleys. It worked great keeping ice out of the hole (on one of only a handful of days this winter it got that cold!!!) and the ducks really were attracted to it. Its designed for those with fixed, all-season blinds because its can take about 20-30 minutes to fully install, plus you'll want to make sure there aren't alot of obstructions to the drive belt, but it worked easy enough. Unfortunately, if there are muskrats or beavers in your area, you'll have to raise it up daily to keep them from gnawing on the drive belt, but this system worked great. This is made locally in Tennessee by a small, family run business, which makes it even better in my eyes. I've posted two videos to show the system in action, so feel free to check them out.
