The Bird-X QuadBlaster QB-4 keeps birds out of facilities
The Bird-X QuadBlaster QB-4 is built to keep birds out of facilities. The QuadBlaster QB-4 is an ultrasonic bird control device that emits high-frequency sound waves engineered to deter birds. The audio attack is silent to humans. The QB-4 is designed for use indoors or in semi-enclosed spaces in order to contain the ultrasonic sound waves, allowing them to reflect off of walls and other barriers. The electric oscillator is tuned between 22 and 30 kHz and is designed to cover up to 6,500 sq. ft.
