K&K M4700 – The Complete Marten Repellent Device: Marten Repellent Ultrasonic + High Voltage Waterproof, 6 Sliding High Voltage Plates, 360° Ultrasound

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.

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.

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 completely moulded electronics and a completely closed speaker according to IP 67 standard allow deep installation even in splashing water areas. Even engine washes are no problem.

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.
