Ultrasonic car repellent, protection against martens - Connection to a 12V car battery in the engine compartment for car, attic, garden, etc.

The marten repellent is powered by a standard 12V car battery, so no additional power supply is needed. It is easy to install and use. It features reverse connection protection and an automatic self-test upon power-up. It uses alternating ultrasonic waves and a powerful flash to prevent habituation and effectively deter animals. The device has a built-in sensor that automatically turns the marten repellent on and off when the vehicle is pre-switched off. If the voltage drops below 9.2V, the alarm and low-voltage protection activate to prevent battery drain and protect the battery.
