Help manage excessive barking with this automatic ultrasonic bark control device (U58). Built-in microphones detect barking and the device responds with an ultrasonic tone designed to discourage repeated barking, stopping when the barking stops.

Choose from two ultrasonic frequencies (fixed 25 kHz or variable) and three detection ranges — 15, 30 or 50 ft (approx. 4.5, 9 or 15 m) — with your settings shown on the LED screen.

A built-in 1200 mAh rechargeable battery charges via USB Type-C in about 2.5 hours, with up to 2 months of standby time. Two keyholes on the back let you hang it on a wall, fence or tree; outdoors, choose a sheltered spot and keep it dry.

Ultrasonic sound may not work the same for every dog. For best results, use alongside positive reinforcement and consistent training.
