Kemo Ultrasonic loudspeakers set off from the marten guard

Generates strong, pulsating ultrasonic sounds that are perceived as very disturbing by martens and other rodents, thus helping to scare them away. This marten repeller comes with four small ultrasonic speakers to ensure good distribution of the ultrasonic sounds. If a marten protection device is installed at only one location in the engine compartment, "sound shadows" may occur due to the engine. Distributing the speakers in different locations can prevent this. The cables to the speakers can be up to 50 meters long.
