The device has three different ultrasonic frequency settings, tailored for small and large mammals, and can be set to activate either at preset intervals or via a motion sensor. The sound changes continuously, preventing animals from getting used to the noise or developing resistance. It can be mounted on a wall or embedded in the ground with the provided stake, and it operates on two 9V batteries (not included) and is ready for immediate use. Its range reaches up to 200 sq m.
