Isotronic
2-piece set of professional ultrasonic marten deterrents for cars

Acoustic marten deterrent prevents gnawing damage to vehicles: When martens choose the engine bay as a warm spot, they often chew through ignition cables and rubber hoses, causing dangerous damage. Protect the engine bay with this device, which repels the animals using ultrasound. The frequency range from 12 to 23 kHz is inaudible to the human ear but effectively drives martens away. For martens, these ultrasonic tones, emitted at 3-second intervals, are very unpleasant. The ultrasonic waves spread at an angle of 140 degrees and the martens look for another place. This effectively prevents marten bite damage without harming the animals. Prevent annoying and costly damage to cables and insulation material around the vehicle engine with the Marder-Frei Profi. In extreme cases, the vehicle may come to a standstill if, for example, marten bite damage is not noticed immediately. This can cause significant damage to the car.

Easy installation, even for laypersons: The Marder-Frei Profi is connected directly to the car battery using the supplied cables. Simply fasten the device in the engine bay with cable ties. When the ignition is switched on, the device automatically turns off to save power.
