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.
