The Sentinel ultrasonic bird and Pigeon repeller is a commercial grade, very powerful unit. It has adjustable frequencies for fine tuning to match the hearing of your target pest. It's extremely effective with a huge 50 mtr (150 ft) range per satellite speaker. The ultrasonic bird repeller produces a pulsating and aggressive ultrasonic sound, similar to a siren but silent to humans, which a bird perceives as extremely unpleasant and therefore avoids the area being protected by the Sentinel deterrent.


This model has 2 satellite extension speakers that can be mounted upto 5 mtr away from the base unit. This has the benefit of controlling specific areas. The extension speakers plug into the base unit which is mains powered. Each speaker comes with a mounting bracket which can be adjusted to different angles.

The base unit is supplied with a mains adaptor & approximately 10 mtr of cable complete with a wall mounting bracket. The speakers and base unit are 100% waterproof for all year round outside use. 

Unlike the lower priced battery operated models, this powerful ultrasonic repeller requires a 240v mains power supply. And because it is mains powered, the Sentinel is always working, giving protection 24/7.

The Sentinel bird repeller is made in the UK using German components.

The main reason why the Sentinel ultrasonic repeller stands head and shoulders above other models is because the frequency is adjustable. The user can very easily adjust the sound to get the optimum effect for the animal you are targeting.

And because the frequency of the ultrasonic unit is adjustable, it can also be made to repel rats, mice, squirrels, foxes, cats, badgers etc, Please note that the Sentinel deterrent can only be set to repel one animal type at a time. In other words, it can't repel cats and birds at the same time because the animals have different hearing ranges.

It can be run from a 12v heavy duty battery or by a mains adaptor (supplied).
