The Bouncer from Sillosocks is a great way to add realistic movement to your decoy spread. The Bouncer simulates feeding birds. Birds are always looking for the best spot to feed and are constantly hopping over birds to get there. When used in conjunction with our Sillosock flappers the bouncer will add a new dimension to your spread. For Canadas, think of it as a remote flagger. The Bouncer comes with a manual speed control with 20 feet of cord to allow you to control the unit from your blind. The bouncer can be used with one or 2 arms. For field duck hunting, try it with our JUST WINGS- new spinning wings to simulate feeding mallards. The bouncer includes 2 arms and a manual speed control. It will run off of any 12 volt battery. Battery and flyer not included.
