Isotronic M480 Repeller

Ultrasonic Marten and Rodent Repeller

This battery-powered ultrasonic repeller is designed to protect vehicle engine compartments, garages, storage areas, and other enclosed spaces from martens and small rodents. The device generates high-frequency sound pulses that are nearly inaudible to the human ear but are an unpleasant stimulus to animals, deterring them from entering the protected area.

The device operates continuously, day and night, emitting ultrasonic pulses at regular intervals. Thanks to integrated Q-technology, a stable emission level and precise interval switching are ensured, which helps prevent animals from becoming accustomed to the transmitted signal.

A built-in vibration sensor automatically detects when the engine is started and shuts off the device. Once the vehicle is parked and the vibrations stop, the repeller automatically reactivates. This conserves energy while ensuring protection only when it is actually needed.

The device has an IP44 rating, which provides protection against splashing water and allows it to be used in a vehicle’s engine compartment. Thanks to its very low power consumption, the operating time on a single set of batteries is up to approximately 12 months.
