Sentinel Ultrasonic Cat / Bird / Dog Repeller with adjustable frequency

100ft range
Sentinel Ultrasonic repeller with 100ft range

The latest addition to our range of ultrasonic repellers is the Sentinel, our most powerful model yet, with a massive range of up to 100ft. The one huge advantage this model has above all the others is that the ultrasonic frequency is adjustable. It means that the user can change the frequency to repel different animals and also “fine tune” the output for the particular location. For example, if you were to mount the repeller in a large building, such as a warehouse to repel Pigeons, the acoustics inside the property might need the tone to be a little higher or lower than if mounted outside. Simply turn the dial on the base of the Sentinel ultrasonic repeller to adjust the frequency either higher or lower.

The Sentinel ultrasonic repeller produces a pulsating and aggressive ultrasonic sound similar to a siren which a bird, pigeon, cat, dog, rat, squirrel etc, perceives as extremely unpleasant and therefore avoids. Please note that it can only be set to repel one animal type at a time. In other words, it can’t repel cats and mice etc, at the same time because animals have different hearing ranges.

What’s an ultrasonic bird repeller?

We often get asked what is the difference between and audible bird repeller and an ultrasonic bird repeller?

audible-electronic-bird-scarer-repeller-upto-1-acre--60-p[ekm]176x200[ekm]

To put it simply, “audbile sound” means that the noise the bird repeller produces can be hear by humans as well as birds. Ultrasonic sound is outside of the human hearing range and so it cannot be heard by humans.

Ultrasonic sound is so high pitched that only birds can hear it. They find it anonoying and so want to leave the area. Its not harmful, just annoying. And very effective!
