Get Off Ultrasonic Fox & Dog Repeller

A chemical free solution for repelling unwanted foxes and dogs from your
garden or any outdoor area, 24 hours a day, 365 days a year. Inaudible to
humans, this battery operated unit uses PIR technology, releasing a high
pitched sound when the beam is broken. This sound is inaudible to humans
but unpleasant to foxes and dogs, who will quickly move away from the
treated area. With a large coverage area of up to 6000sq ft.
