Marten defence, ultrasonic device with aggressive sinusoidal ultrasonic tones, which are perceived as extremely annoying by martens

To deter martens in camping vehicles, the ultrasonic device generates aggressive sinusoidal ultrasonic sounds that are inaudible to humans, which martens find extremely annoying and therefore avoid if possible.

Optional installation service

We install the marten repellent invisibly in the engine compartment. The power is supplied next to the original fuse box of the body battery. The sensor is positioned behind the radiator grille to optimise sound propagation. This allows the sound to spread inside and in front of the motorbike.
