New Ultrasonic Tube from Pigeon Patrol
Sonic sound emitters, are one of the most effective deterrents on the market. Consisting of a central unit together with a Tweeter, the system emits distress calls and calls of predators of the target species as well. Effective emitters randomize pitch, magnitude, time interval and other factors to prevent birds’ getting used to them.
Ultrasonic electronic devices produce high pitch emissions in ultrasound. The sound is designed to be too high pitched for people to hear, but audible to most birds. This has the advantage to preventing disturbance to neighboring households.
