Waterproof 2.0: A waterproof moulded electronics and waterproof components according to IP 65 standard allow deep installation even in splashing water areas. Even engine washes are no problem.
Sleep mode: the built-in sleep mode of the activation sensors, only takes up the AA batteries on contact and "snoozes" the rest of the time.
Self-sufficient battery device: Thanks to the battery operation, high-voltage devices can be operated completely independent of the electrical system. This is particularly advantageous for electric vehicles, motorhomes, vintage cars and others with long service life. A low battery indicator with LED warns early if the batteries in the device are empty.
Multi-contact high-voltage brushes: multi-contact brushes pass through the insulating fur and – in addition to paws and snout – the active surface is extended by the factor skin and thus many times over. In addition, an environmentally independent installation is possible.
High voltage (pasture fence principle): "Who does not want to hear must feel!" Older martens (other hearing behaviour) or very aggressive animals (field battles) can sometimes only be driven away by electric shock.

Waterproof 2.0: A waterproof moulded electronics according to IP 67 standard and a completely closed speaker allow deep installation even in splashing water areas. Even engine washes are no problem.
Pulsating sine wave ultrasound: our marten scares imitate the warning screams of animals very lifelike and extremely loud. This works and prevents the habituation effect.
Note for electric vehicles & motorhomes: this marten repellent device switches off automatically when the engine is running (12V voltage change). Important: even when connecting to external power sources (e.g. charging stations, shore power, solar system), this shutdown takes place. For continuous protection in such cases, self-sufficient devices with their own power supply (e.g. Model M9700). Additional information for motorhomes: If your vehicle has an independent 12 V supply, a connection device can also be used.
Multi-contact high-voltage brushes: multi-contact brushes pass through the insulating fur and – in addition to paws and snout – the active surface is extended by the factor skin and thus many times over. In addition, an environmentally independent installation is possible.
High voltage (pasture fence principle): "Who does not want to hear must feel!" Older martens (other hearing behaviour) or very aggressive animals (field battles) can sometimes only be driven away by electric shock.
All-round ultrasonic emission: The dome speaker emits the sound waves over 360° to all sides. Sound shadows are thus avoided and all-round protection against martens is achieved

Main highlights

Ultrasonic marten deterrent car: variable ultrasonic frequencies, LED flash light and acoustic signals support effective marten defence in the engine compartment and around the vehicle. The integrated anti-habituation effect thanks to changing stimuli helps keep martens, mice and other animals away in the long term and protect cables and hoses from damage.
Sensor control with active and standby mode: thanks to the integrated motion sensor, the marten repellent works fully automatically. In active mode (when the vehicle is station), the device is ready to use. In standby mode (while driving), it reduces power consumption. An additional interval operation (10 seconds active, 100 seconds pause) prevents the animals from getting used to the ultrasonic waves.
5️⃣ Start of effect after 3-4 weeks and box contents: continuous sound with changing frequencies usually takes 3-4 weeks to permanently repel martens and weasels. Actual effect may vary slightly depending on the environment. Box contents: marten deterrent, DC5-12V car battery cable, Type-C charging cable, cable ties (4 pieces), manual (English language not guaranteed). If you have any questions, our customer service is available.
4️⃣ Versatile use for engine compartment, roof floor and house: the device is ideal for cars, motorcycles, attics, residential houses, storage rooms and garages. Important note: the marten deterrent is not waterproof. Therefore, use it only in dry, covered areas - not outdoors in rain or wet.
3️⃣ Flexible power supply – Type-C, AA or car: you have the choice: operate the marten protection with 4 AA batteries, via the modern Type-C socket or directly on the vehicle battery (only for the engine compartment). Installation with cable ties or screws is done in 2 minutes. Perfect for car, garage, attic and home.
