  • A dog fence system you can bury and hide under the ground
  • To install – bury the wire around the perimeter of your yard and plugging in the transmitter.
  • System comes with 1000 feet of 20-gauge boundary wire and 100 flags to contain up to 1 1/3 acres of land.
  • System can be expanded to cover up to 100 acres with the purchase of additional SDF-WF Wire & Flag Kits
  • System can be expanded to contain an unlimited number of dogs with the purchase of additional SDF-R Add-A-Dog Collars. 
  • Collar has a low battery indicator so you can tell when to change the battery
  • Collar has anti-Linger feature to prevent your dog from running the battery down by standing in the warning zone.
  • Collar takes a standard 9-volt battery that lasts 6-12 months (Best with Polaroid 9V Batteries)
  • The Collar Receivers fit any small, medium, large, or extra large sized dog over 10 pounds
  • The Collar Receiver sends a tone and vibration as your dog approaches the boundary, and moves to one of 4 static correction levels that you select, based on your dog’s temperament
  • The Fence Transmitter is wall mountable
  • The Fence Transmitter features a built-in lightening protector to help avoid damage from lightning strike or power surge, as well as a wire break alarm to alert of a break or cut in the underground wire. 
  • Comes with an Operating Guide, and customer support
  • There are both 20 gauge (thinner wire) and 14 gauge (thicker/stronger wire)

How it works…

  • The system works by producing a radio signal from the Fence Transmitter through the Boundary Wire. The Boundary Wire is buried or attached to a fixed object to enclose the dog’s Boundary Area. You temporarily define the Boundary Area with Boundary Flags for a visual aid in training your dog.
  • Your dog wears a Collar Receiver with Contact Points that touch his neck and, once trained, is allowed to roam freely in the Boundary Area. When your dog reaches the Warning Zone, the Collar Receiver gives a warning beep. If your dog continues into the Stimulation Zone, a safe stimulation will be delivered through the Contact Points to get his attention until he returns to the boundary area
