Produces strong, pulsating ultrasonic sounds that are perceived as very disturbing by martens and other rodents, thereby driving these animals away. This marten deterrent comes with four small ultrasonic speakers to ensure good distribution of the ultrasonic sounds. If a marten protection device is installed in only one spot in the engine compartment, "sound shadows" can 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.
