EXTREME ULTRASONIC SYSTEM SD-NM10

The Extreme Ultrasonic System projects 130dB of ultrasound from a single tweeter mounted on the face of the weather-resistant device. The single tweeter can project ultrasound out to an unobstructed radius of 50 feet in a 90-degree arc from the center of the device, covering approximately 2000 square feet in a fan shape. It produces sounds in no predictable pattern so the birds do not become accustomed to the noise and will drive away roosting or nesting pigeons when used properly. The Extreme operates at frequencies above that of average human hearing, so it is ideal to deploy in public areas where pigeons are nesting.
