The Deluxe Ground+ Fence is a modern and highly effective system enabling you to keep one or more dogs in complete freedom within a perimeter, fenced or unfenced, you have defined. You can define your dogs play area by installing a wire, called antenna wire, around the authorized perimeter. This wire placed on the ground, buried or raised on an existing fence carries a radio signal from the transmitter. When your dog, wearing a receiver collar, approaches this wire, he is warned by beep sounds that he is too close to an area where he is not allowed; then if he carries on, static stimulation will be emitted by the collar.
