LVPRN 4X Anti Barking Device for Dogs, Automatic 270 Bark Control with 4-Way Emitters 50FT Rechargeable IPX5 Ultrasonic Stopper Garden, Fence & Patio

4-WAY OUTPUT FOR MULTI-DIRECTION BARKING AREAS: Instead of sending ultrasound in only one direction, this anti barking device for dogs features four emitters designed for wider 270° coverage. Used as an ultrasonic dog barking device, it helps target common dog barking areas around fences, patios and gardens while reducing the need to constantly reposition a standard anti bark device. 20 / 25 / 30 kHz + AUTO VARIABLE FREQUENCY: Four selectable modes give this anti dog barking device more flexibility for different surroundings and dog responses. Select a fixed frequency or use AUTO 20–30 kHz for changing output, making it a practical ultrasonic dog barking deterrent when you want to stop dog barking without depending on only one ultrasonic tone. AUTOMATIC, COLLAR-FREE EVERYDAY OPERATION: There is no need to press a handheld button each time barking starts. Once installed and switched on, the unit is designed for automatic operation, helping these anti barking devices fit more naturally into daily routines. It works as a stop barking dog device, bark stopper for dogs and ultrasonic bark stopper without requiring your dog to wear an electronic collar. 50FT RANGE, IPX5 & USB-C RECHARGEABLE DESIGN: This anti dog barking device outdoor solution is designed for common British garden settings, including fence lines, patios and outdoor dog areas. The IPX5 housing supports regular outdoor use, while the USB-C rechargeable battery can provide up to 30 days of use, making the unit a convenient anti barking device for longer-term placement. CLEAR DISPLAY, EASY SETUP & REALISTIC EXPECTATIONS: Check battery level and working mode directly from the screen, then adjust the rotary selector as needed. This anti barking system can suit small, medium and large dogs depending on hearing sensitivity and placement. Rather than relying on a strongest anti barking device claim, correct positioning and a clear line of sight matter to performance. This product can also function as an ultra sonic dog bark stopper and is not intended for deaf or hearing-impaired dogs.
