Isotronic M407 Repeller

12V/24V Ultrasonic Marten and Rodent Repeller

This ultrasonic repeller is designed to protect the engine compartment of vehicles from martens, rodents, and other small animals. It emits high-frequency sounds that are nearly inaudible to humans but are unpleasant to animals. This helps prevent damage to wiring, hoses, and other important vehicle components.

The device operates automatically day and night, emitting ultrasonic pulses at regular intervals. Short transmission cycles help reduce the risk of animals becoming accustomed to the sound and ensure long-term protection. The wide beam angle allows for effective coverage of most of the engine compartment.

Powered directly from the vehicle’s electrical system, it operates maintenance-free without the need to replace batteries. With support for both 12V and 24V electrical systems, the repeller is suitable for passenger cars, vans, and trucks.

The compact design and long power cable facilitate installation in a suitable location within the engine compartment. Low power consumption ensures minimal strain on the car battery, even during long-term operation.
