Deramax-Bird Ultrasonic bird scarer (repeller)

The Deramax-Bird ultrasonic scarecrow protects the area from birds, like pigeons, starlings, Sparrows, Scythes, ravens or crows. It produces strong ultrasonic signals that are very unpleasant for birds, which makes them leave the area after a short time. It has an automatic frequency change within a given range, so birds do not get used to the signal, and at the same time an automatic power change, which contributes to the efficiency of the scarecrow. Its operation is chemical-free, and the range of efficiency reaches 25 metres at an angle of approximately 180°. Any number of scarecrows can be used in one location and their signals do not negatively affect each other. The larger the area to be protected from birds, the more scarecrows can be used.
