Professional ultrasonic marten repeller for cars – effective protection against gnawing damage – 12–24V, 23 kHz, 140° emission angle, 0.1 W – easy installation

Acoustic marten deterrent prevents gnawing damage to your vehicle: When martens choose an engine compartment as a cosy warm spot, they often chew through ignition cables and rubber hoses, causing dangerous damage. Protect your engine bay with this device, which deters martens by means of ultrasound. The frequency range from 12 to 23 kHz is inaudible to the human ear, but effectively repels martens. For martens, these ultrasonic tones, emitted in 3‑second intervals, are extremely unpleasant. The ultrasonic waves spread out at an angle of 140 degrees and the animals look for another place. In this way, marten bites can be effectively prevented without harming the animals. Use the Marten-Free Pro to avoid 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 is straightforward, even for non-professionals: The Marten-Free Pro is connected directly to the car battery using the supplied cables. Simply fix the device in the engine compartment with the included cable ties. When the ignition is switched on, the device turns off automatically to save power.
