YardMax® Rechargeable In-Ground Fence maximizes the amount of yard space for your pet to play freely in and around. Our most reliable and advanced In-Ground Fence system, YardMax® keeps your pet in your yard with a transmitter and rechargeable collar. You'll bury wires in your yard to set your pet's boundaries. When your pet nears the boundary, the collar will give a warning beep, followed by a static correction to remind your pet to stay within the boundaries. Your pet will be enjoying greater room to roam in no time!
