Anti-Rodent Module

Extremely effective battery-powered ultrasonic device. Frequency modulation ultrasound that alerts martens to "maximum danger" using animal sounds of fear and alarm. No inurement effects. Independent of the on-board circuit thanks to two standard 3-volt button batteries (CR2477), which have a particularly long life of approximately 24 months per set of batteries. Ideal for long-term parking situations, such as old vehicles, camper vans or display vehicles and vehicle shelters.
