Effective protection against martens

The K&K M2500 anti-marten device is designed to protect your car from marten damage. By emitting pulsating ultrasonic sine tones at a frequency of 23 kHz and a sound pressure of approximately 105 dB, this device creates an unpleasant environment for martens, causing them to avoid your vehicle. These tones are inaudible to the human ear.

180° ultrasonic coverage

Thanks to the special placement of the speaker openings, the M2500 device emits sound waves at a 180° angle. This provides wide coverage in the engine compartment, effectively deterring martens from potential bite-sensitive areas.

Easy installation

The device is connected directly to your car's 12V battery and has a low power consumption of less than 2 mA. The built-in LED indicators flash to show the device is operating and simultaneously enhance the deterrent effect.

Application possibilities

The M2500 device is not only suitable for installation in cars, but can also be used in buildings such as garages and attics to keep martens away. Installation in the engine compartment should be done in such a way that the device is protected from direct dirt and water, and that the ultrasonic signals are effectively distributed to the areas most susceptible to marten damage.

Important considerations

For optimal effectiveness, it is recommended to remove existing marten scent traces by thoroughly cleaning the engine or using a scent remover. This prevents martens from being attracted by previously left scents and increases the effectiveness of the M2500 device.
