Marten Defence for Motor Vehicles 12 V/DC M186 Kemo - Made in Germany

Double protection against martens: A high ultrasonic tone is emitted via the built-in piezo ultrasonic tweeter martens avoid this sound as far as possible. Should an animal still manage to find its way into your car, a high-voltage disc mounted in the engine compartment gives it an electric shock, causing it to run away. Both types of protection are harmless to humans and animals.
