1. Invisible environmental protection: the wires are buried underground, do not occupy space, do not affect the appearance, give the dog more freedom
2. Progressive tone stimulation: When the dog approaches the boundary, a warning sound is issued first. If you continue to approach, the system will deliver a slight shock
3. Pulse proportional stimulation: Humanized high-tech design, the vibration intensity depends on the distance of the dog close to the boundary line, the closer the dog is to the boundary line, the greater the vibration intensity
5. Built-in speed detector: the faster the dog moves, the higher the level of emission intensity
6. The control range is wide, and the knob of the transmitter can be adjusted to adjust the size, which is convenient for operation
7. When the buried wire is damaged, the wire damage indicator will emit a loud warning and flash
