Humane Goose Decoy Device: The Bird-X GooseBuster is a one-of-a-kind and humane system that employs naturally recorded frightening cries, forcing geese to evacuate quickly from the treated spaces without identifying the source. Uses Alarm and Alert Calls: By using naturally recorded alert calls that let geese know there is potential for trouble and alarm calls that signify immediate danger, our sonic device makes an uninhabitable area for geese, ducks, and other waterfowl. Weatherproof and Customizable: The GooseBuster's weather-resistant control box is designed to withstand outdoor use. Also, the unit is customizable with frequency, sound, and duration settings, and it even has optional coyote bark and gunshot sounds. 4-Speaker System: With its four-speaker system, the GooseBuster covers up to 7 acres and can be combined with another unit to cover up to 21 acres. This sonic device is perfect for areas like ponds, hospitals, parks, airports, golf courses, and more. Easy to Install: Our goose decoy device comes with all mounting hardware, including a 1-amp, 110-volt adaptor, and a 6-foot power cord that makes installation a breeze. The control unit measures 12" x 10" x 7", and each speaker measures 10" x 8" x 5".
