M2500
The POPULAR marten repellent device
With a radiation angle of 180 degrees, the M2500 delivers ultrasonic waves where their protective effect is most needed. The speakers of the M2500 are specially designed and arranged in such a way that the pulsating sine ultrasound not only beams forwards, but also laterally through specially-designed slots.
Sound waves spread like light, but obstacles can block them. An ‘acoustic shadow’ then develops, which receives hardly any of the sound pressure. For martens, the acoustic shadow is the perfect hiding place. The M2500’s specially-designed speakers make it highly effective over a wide area. This makes the game of hide and seek in the engine compartment a futile exercise for the marten.

Product features
-
Pulsating sine ultrasound Our marten-scarers mimic the warning calls of the animals in a very loud and highly lifelike way. This serves to prevent the habituation effect.
-
180° waves Ultrasound waves spread forward light, i.e. the sound is barely perceptible behind obstacles or from the sides. The special way in which the loudspeaker is designed and placed means that the aggressive ultrasonic sine tones are emitted in a beam angle of 180 degrees. -
CAN bus The electronics of modern vehicles communicate internally via a so-called CAN bus. Even in this environment, our devices can operate without any difficulty.
-
Recommended for electric and plug-in hybrid vehicles This ultrasonic device is ideally suited for all engine generations and is also recommended for electric vehicles and plug-in hybrids.
-
E1 mark The E-1 sign confirms that the device has been tested by the Federal Motor Transport Authority (KBA).
-
Acid-proof, self-extinguishing plastic The device is resistant to acids (e.g. batteries or cleaning agents) and the plastic used meets automotive industry safety standards.
