Ultrasonic Electronic Deer Alert
This Ultrasonic Deer Alert only has two wires to install, so you can hook it up to your vehicle with minimal effort. The Deer Alert turns on automatically when you start your car, sending out ultrasonic sounds that animals can hear from up to 1,500 feet away (457 meters). The ultrasound is emitted for as long as your car is on, and turns off automatically when you remove your key from the ignition.
The Deer Alert will not clog with dirt, debris, or grime which make many other animal-warning devices inoperable. Trailblazer is rugged and weather resistant. 12 Volts, 103 Decibels.
