- Functional principle: This marten deterrent uses changing ultrasonic waves in the 15-36 kHz range, paired with a flashing light, to repel martens. It is designed for ongoing use, and results are best observed after 2-4 weeks of continuous operation. - Wide range of applications: The device can be powered by 4 AA batteries, a 5-12 V car power supply, or USB. It can be installed in attics, garages, car engine compartments, and other similar spaces. Effective coverage is 40-50 square metres. - Intelligent operation: When connected to a vehicle, the built-in vibration sensor activates automatically when the car starts and the device pauses. After the car stops for 120 seconds, the device reactivates and continues in working mode. - Safe and unobtrusive sound: The deterrent emits ultrasonic waves that are inaudible to people and pets, while disturbing the martens to reduce nuisance and protect your space. - Practical use scenarios: - Protect your car by installing the unit in the engine bay to deter martens from nesting or gnawing near critical components. - Use in an attic to safeguard stored items and reduce droppings or damage from martens. - Place in a garage or workshop to maintain a pest-free environment without disturbing inhabitants. - Key attributes at a glance: functional principle (ultrasound with flashing light), power options (4 AA, 5-12 V car power, USB), coverage area (40-50 square metres), intelligent behavior tied to vehicle operation, and a humane, inaudible deterrent for humans and pets.
