The Rechargeable In-Ground Fence is the convenient containment system that lets you keep your dog safe in your yard without having to regularly replace collar batteries. Installation of the system can be done in one weekend with some basic DIY skills. To install, you simply bury wire around the perimeter of your yard to set a custom boundary. Your containment area can be up to 1/3 acre with included wire and up to 25 acres with additional wire. The system works through a radio signal sent from the transmitter in your home, the transmitter communicates with the buried wire and your dog?s rechargeable receiver collar to warn and then give your pet a static correction should he try to leave his boundary. After about 2 weeks of training, your pet will quickly learn his boundaries. He will enjoy freedom and fun in his new outdoor home.
