Ultrasound with frequency modulation - independent of on-board network
Highly effective ultrasound device with battery operation. Frequency-modulated ultrasonic tones that mimic animal cries of fear and warning, signalling extreme danger to the marten. No habituation effect. Independent of the on-board network thanks to operation with two standard 3-volt button cells (CR2477), particularly long service life of approx. 24 months per set of batteries. Ideal for long-term parkers such as vintage cars, mobile homes, exhibition vehicles or for the carport.
