Ultrasonic Bird & Pigeon Repeller (300 ft)

Product code: sen3way

Product information

The 3 way Sentinel is our best and most powerful ultrasonic bird & Pigeon repellent / deterrent that has an adjustable frequency. It has 4 speakers that send ultrasonic sound 150ft in 3 different directions. 

It's hugely effective with a massive 150ft (50 mtr) range in each direction, making a total of 300ft (100mtr) left to right. The ultrasonic bird repellent / deterrent produces a pulsating and aggressive ultrasonic sound, similar to a siren, which birds perceive as extremely unpleasant and therefore avoid.

The bird repeller is supplied with a mains adaptor and wall mounting bracket and can be swivelled & tilted to suit directional requirements. It is100%  waterproof for outside use. 

Unlike the lower priced battery operated models, this powerful ultrasonic bird repeller uses a higher voltage power supply and so needs to be plugged into the mains. And because it is mains powered,  the Sentinel is always switched on, giving protection from birds and Pigeons 24/7. It comes complete with a mains adaptor and 10mtr cable. 

This device is not an instant fix for pest problems. It's a gentle approach to pest control and can take up to 2 weeks to make a difference. If you are looking for an "instant fix", the Multisound audible bird repeller might be worth looking at. MORE INFO>>>>>>>

This repeller is made in the UK using German components

The main reason why the Sentinel ultrasonic bird / pigeon repeller / deterrent 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 specific creature you are trying to repel.

And because the frequency of the ultrasonic deterrent is adjustable, it can also be made to repel rats, mice, squirrels, foxes, cats as well as birds etc, Please note the Sentinel 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 those animals have different hearing ranges.
