Sentinel repeller

The Sentinel ultrasonic repeller keeps your garden free of unwanted pests. The unit emits a high frequency sound that is silent to humans, but irritating to animals such as birds, cats, dogs, badgers and many more. With a range of 50 mtr, the waterproof deterrent is mains powered giving protection 24/7. The ultrasonic noise is not painful or cruel, just annoying to a nuisance animal.

As seen in:

The ultrasonic repeller produces a pulsating and aggressive ultrasonic sound, similar to a siren but silent to humans, which an animal perceives as extremely unpleasant and therefore avoids the area.

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.
