The Sportdog In-Ground Rechargeable Fence System gives you a dependable way to keep your dog safely contained without traditional fencing. This wire-based containment system works by establishing a boundary around your property—bury the included wire or use it above ground—and your dog wears a compact collar receiver that communicates with a transmitter. When your dog approaches the boundary, the receiver delivers a warning beep and vibration first; if he continues closer to the wire, a static stimulation gets his attention until he backs into the safe zone. It's a hands-off way to let your dog roam freely within a defined area.
Setup is straightforward: the included 1000 feet of boundary wire and 100 flags let you establish a containment area up to 1 1/3 acres right out of the box. The system is expandable—buy additional wire and flag kits to cover up to 100 acres, or add more dogs by purchasing extra collar receivers. The collar receiver itself is compact and sleek, and it's built tough: DryTek waterproof technology means it handles wet conditions and can even be submerged to 25 feet. A rechargeable lithium-ion battery charges in two hours and lasts one to two months per charge, so you're not fussing with disposable batteries.
Training flexibility is baked in: seven levels of static stimulation let you match correction intensity to your dog's temperament, and you can also use vibration and tone as warnings before any stimulation. The anti-linger feature prevents your dog from wearing down the battery by hanging in the warning zone. An alert on the transmitter warns you if the boundary wire breaks, and built-in lightning protection gives you peace of mind during storms. Suitable for dogs 10 pounds and larger, this system is designed for dogs that understand basic obedience and are ready to learn their boundaries.
