YardMax maximizes the amount of yard space for your pet to play freely in. PetSafe's most reliable and advanced in-ground fence system 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 yard freedom in no time!
