Avian X X-Factor Decoy Motion System - The X-Factor Motion System is a remote-operated solution that appeals to birds' natural curiosity by adding realistic movement to any setup, anywhere. Ideal for highly mobile, run-and-gun-style hunters, it's as compact, lightweight and easy to carry as it is simple to deploy. Features Motion box wrapped in rugged, water-resistant housing that delivers protection in any weather conditions. Push-button remote control and motion cord, which allow hunters to power the unit discretely from a distance. Two tough-as-nails field stakes to ensure the whole unit remains upright and operating right where you left it. Four AA batteries (not included) provide enough power to keep the system operating for as long as 12 hours. Check local laws on remote control decoy use.
