Ultrasonic Bird Repeller

The QuadBlaster QB-4 repels birds using ultrasonic sound. Four Piezo ceramic speakers project powerful sound waves in an overlapping fan pattern.

The speaker sequencing, frequency and warble rate can be adjusted, making it difficult for birds to acclimate. The unit features no motor and no moving parts; it can be mounted in any direction.
