Description
How Quadblaster QB4 WorksThe Quadblaster QB4 is an ultrasonic sound generator that is equipped with several features to enhance its effectiveness and ability to provide both immediate and long term control. The QB-4 is an electronic oscillator tuned between 22 and 30 khz, beyond the range of human hearing, but perfectly audible to many pests. The intense ultrasonic sound is measured at 112 dB, nearly equivalent to a jet airliner taking off.
- 360 DEGREE COVERAGE: Sounds are emitted from four built-in speakers and surround the area with ultrasonic sound waves. The effective coverage area is up to 6,500 square feet (approximately 605 square meters).
- ENVIRONMENTALLY FRIENDLY. Does not harm the pest animal or humans.
- ACCESSORIES. Remote extension speakers. For unusual space configurations or areas divided by walls, use up to four remote speakers to stretch sound farther.
