Main highlights

The marten deterrent produces almost no noise during operation. However, the ultrasound can be perceived in the frequency range from 20 kHz to 50 kHz, especially when approaching 20 kHz, by hearing sensitive people. However, this is not a product defect.
Effective marten defense: three operating modes for marten repellent in change, with fixed frequency mode 25kHz + variable frequency mode 20-50kHz + 10Hz flash. The frequency change combined with the extension of the operating time after each cycle of each mode ensures that the animals do not get used to the sound and ensure long-term marten defense.
Easy installation: connect the device to the vehicle battery and attach it to the engine compartment with the mounting strap. Then turn on the device and it is ready to use. The entire installation is very simple and takes no more than five minutes.
Auto Power On/Off: This device has an automatic detection function. While driving, the marten deterrent pauses and is automatically activated as soon as the vehicle is switched off.
