Product information

The Sentinel is a commercial grade, very powerful ultrasonic bird and Pigeon repeller / deterrent with an adjustable frequency for fine tuning to match the hearing of your target pest. It's extremely effective with a huge 100ft range. The ultrasonic bitrd 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.

The ultrasonic bird repeller is supplied with a mains adaptor & approximately 10mtr of cable complete with a wall mounting bracket that can be swivelled & tilted to suit directional requirements. It is 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 animals have different hearing ranges.

All units are supplied with fixing screws for attaching to a wall or fence. It can be run from a 12v heavy duty battery or by a mains adaptor (supplied).
