This Sonic Cat Repeller will help protect your garden habitat and encourage wildlife and birds back into it. The Big Cheese incorporates a sophisticated PIR (Passive Infra Red) detection system, which constantly monitors a fan shaped area of a 98 degrees arc up to a distance of 12 metres. The protected area is over 120sq. meters of unobstructed space. It detects animals moving into this area and triggers a burst of continuously variable ultrasound, which sweeps a frequency range of 18,000Hz, 24,000 Hz to repel them. Simultaneously the LED indicator on the front of unit signals that it is now activated.

Powered by two 9V alkaline batteries which is conserved by the PIR detection system, which allows the unit to remain on stand-by between activation periods, therefore maximizing battery life.
