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
