Ultrasonic Anti-Bark Device, Safe and Harmless, Training Aid with LED Flashlight

Train effectively and quietly without disturbing your neighbors!
Start a smarter dog life with training that's gentle on both dogs and people!

Training Mode
Training Mode uses ultrasonic waves in the 20-25kHz range.
When the button is pressed, ultrasonic waves of medium, low, and high frequencies are emitted continuously.
This mode can be used to interrupt your dog's behavior when they bark or exhibit other undesirable actions.
Through repeated interruptions and patient training by the owner, your dog can form certain conditioned reflexes, reducing the frequency of incorrect behaviors.
Some dogs may become accustomed to ultrasonic waves. In such cases, please switch to Repellent Mode to continue training.

Repellent Mode
Repellent Mode uses higher and faster frequencies and is suitable for situations where you want to deter or drive away dogs.
Repellent Mode uses 25kHz ultrasonic waves, and when the button is pressed, ultrasonic waves are emitted continuously at a frequency of approximately 7-10 times per second.
