【2024 Upgraded Version】 Goldkaii newly released wireless dog fence boasts a large LCD screen, offering a user-friendly interface for easy setup and control. This wireless fence system combine the function of a wireless dog fence with a remote training collar. Leveraging cutting-edge 2.4GHz signal technology, the electric fence system ensures stable and accurate signal transmission, easily penetrating walls without any interruption. 【Wireless Fence Mode】The wireless fence mode enables seamless connection between the transmitter and multiple collars. The signal range extends from 50ft to 990ft in radius, ensuring ample space for your dog to roam freely. If your pet ventures beyond this designated area, the receiver collar triggers a warning tone, followed by a vibration and a gentle electrostatic shock (3.7V low voltage) to discreetly guide them back. Say goodbye to traditional boundaries and embrace the freedom of a wireless fence, allowing your dog to safely explore their surroundings. 【Training Collar Mode】 In remote training collar mode, this system can control up to 4 dogs simultaneously. You will see A/B/C/D dog from the screen directly, choose the desired dog on the LCD panel and adjust the warning mode and strength with 0-9 levels, tailoring the training experience to your specific needs. If you don’t wanna your dog be shock, just simply choose 0 level under shock mode.
