The MP3B bird repeller is able to cover a greater area than either the MP1B or MP2B by emitting high frequency ultrasonic sound from four speakers, each facing a different direction.

As birds have very sharp eyesight, a strobe lamp that flashes for short periods at random intervals adds a visual deterrent effect making this device ideal for use in larger open areas where birds can cause problems, such as inside buildings and covered areas.

Effective up to 50ft (15m) from the front of the speaker where no obstructions are present, this is important as ultrasonic sound is not able to penetrate any object in the way.

As the repeller device is a single box, mounting is straightforward and a 10m ingress protected lead is used to connect to a power supply.

Each MP3B is supplied with a mains adapter or 12V battery connection for situations where a mains supply is not available or convenient.

If using a battery to power the repeller, then use a 12V car or leisure type, either will work but leisure batteries are more suited to this kind of use, and whilst any size of battery will work, consider using a 50AH or greater capacity, this is particularly important if using a solar charger.
