Main highlights

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

Waterproof 2.0: A waterproof moulded electronics according to IP 65 standard and a completely closed speaker allow deep installation even in splashing water areas. Even engine washes are no problem.
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.
Pulsating sinus ultrasound with all-round ultrasonic radiation: Our marten scares imitate the warning screams of animals very lifelike and extremely loud. This works and prevents the habituation effect. 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

Versatile use: Due to the battery operation, marten defence is possible in the car, in the garage, in the attic, in the house or in the garden. Protect your home
Simply repel martens: The marten deterrent periodically emits high-pitched sounds in the ultrasonic range which are very unpleasant to martens. This means that the martens avoid the area around the device
Internal switch: The frequency of the ultrasound and the time intervals are varied. This prevents a habituation effect and the device remains effective in its defence
German supplier: Our company’s head office is located in Germany
Easy to install: The marten protection is powered by batteries (not included). In continuous operation, the device is effective for about half a year. The batteries can be changed
