Isotronic Dog and cat deterrent

The ultrasonic defense is mobile. A set of batteries (6x AAA Micro per device, included in delivery) has a service life of up to 8 months.
The device emits high-pitched tones at intervals (approx. 5 sec. on and approx. 25 sec. off time). The signals are not audible to humans, but have a disturbing effect on dogs and cats.
The alternating frequency reduces the habituation effect, thus the defense function is not interrupted. To drive away animals that habitually visit a place, 7-14 days can pass.
The effective area covers about 40 square meters per device. The cat and dog deterrent is particularly suitable for outdoor use.
With on and off switch, for house, garden, garage, barn, attic or garden.
