[Stronger Signal & Longer control distance] ???? With 2.4GHz technology and new dual antenna design, the new version signal stability is drastically improved, which is more stable and accurate. We use feet instead of meters to indicate distance (five different radius:100ft/200ft/300ft/500ft/990ft). It's usable in any outdoor terrain. When your dog is out of range, the receiver will beep, and then a low 3.7V voltage mild electrostatic shock discourages the dog from exiting the range.
[Automatic pairing to control multiple dogs] ???? One transmitter can control as many dogs as you want, at the same time, the transmitter and collar receivers are automatically paired without manual operation. (EXTRA COLLARS LINK--https://www.amazon.com/dp/B0818TPG3S). You can choose five different control radius distances: 100/200/300/500/990 feet. The range of the fence is defined as a circle (with selected radius) centered on the transmitter.
