This ultrasonic device features three distinct sound wave modes (22-25KHZ): stable, undulating, and irregular frequencies. Simply choose a mode and press the launch button to emit ultrasonic waves. Using multiple sound waves helps prevent dogs from becoming desensitized to any one sound, ensuring effective training over time.
The device has an effective range of 5 meters, making it ideal for indoor use to help manage dog barking.

The integrated BEEP sound can be used as a training aid. For instance, you can press the BEEP button to call your dog, followed by a reward. With consistent use, the BEEP sound will become a reliable command for summoning your dog.
