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

Acoustic marten repellent prevents bite damage to your vehicle: When martens choose an engine compartment as a warm spot, they often gnaw through ignition cables and rubber hoses and cause dangerous damage. Protect the engine compartment with this device, which uses ultrasound to scare off 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 extremely unpleasant. The ultrasonic waves spread at an angle of 140 degrees and the martens look for another place. This effectively prevents cable damage caused by martens, without harming the animals. With the Marder-Frei Profi you can avoid annoying and expensive damage to cables and insulation material around the vehicle engine. In extreme cases, the vehicle may even come to a standstill if marten damage is not noticed immediately. This can lead to considerable repair costs.

Installation is easy, even for non-professionals: The Marder-Frei Profi is connected directly to the car battery using the supplied cables. Simply fix the device in the engine compartment with cable ties. When the ignition is switched on, the device turns off automatically to save power.
