Product information

Sentinel four speaker ultrasonic bird & Pigeon repeller / deterrent with remote on/off control. The unit has an adjustable frequency for fine tuning to match the hearing of your specific pest. It has one speaker to the left hand side, two speakers to the front and one speaker to the right hand side which give about 300+ degrees of coverage. It's extremely effective with a range of approximately 300 feet (100 Mtr).

The ultrasonic repeller produces a pulsating and aggressive ultrasonic sound, similar to a siren but silent to humans, which a bird or Pigeon hears as extremely loud and unpleasant and therefore avoids the area being covered by the Sentinel bird & Pigeon deterrent. It has 4 speakers that send the ultrasonic sound 150 ft in 3 different directions.

The ultrasonic bird & Pigeon 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 & Pigeon 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, birds, 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.

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