Set of 2 professional ultrasonic marten repellents for cars – Protects against gnawing damage & expensive repairs – 12–24 V, 140° emission angle, 23 kHz, easy connection to car battery

Acoustic marten repellent prevents gnawing damage to the vehicle: When martens choose the engine compartment as a warm spot, they often chew through ignition cables and rubber hoses and cause dangerous damage. Protect the engine compartment with this device, which uses ultrasound to repel the animals. The frequency range from 12 to 23 kHz is inaudible to the human ear but effectively deters martens. For martens, these ultrasonic tones, emitted in 3‑second intervals, are very unpleasant. The ultrasonic waves spread out at an angle of 140 degrees and the martens look for another place. This effectively prevents marten bites without harming the animals. With the Marder-Frei Profi you can prevent annoying and expensive damage to cables and insulation material in the area of the vehicle engine. In extreme cases the vehicle may come to a standstill if, for example, marten damage is not noticed immediately. This can cause considerable damage to the car.

Installation can easily be carried out even by laypersons: The Marder-Frei-Profi is connected directly to the car battery using the supplied cables. Simply fasten the device in the engine compartment with cable ties. When the ignition is switched on, the device switches off automatically to save power.
