Innotek Smart Dog Sd-2100 Pet Containment System - $139.99

Smart Dog in-ground containment systems are simple and easy to install, with only three steps to follow. The system consists of a buried yard wire connected to an indoor radio transmitter. When the dog approaches the wire, the receiver in the collar delivers a brief, harmless correction that discourages it from crossing the boundary. The all-new streamlined, rechargeable collar receiver is totally waterproof. Boundary self-check displays system status. The SD-2100 includes 500 feet of single-conductor ground wire, an indoor wall-mounted transmitter that's capable of signal strengths covering up to 25-acres (with purchase of additional boundary kits), one rechargeable collar receiver with neckstrap, boundary wire, training flags and video. - $139.99
