Whats the difference between the different PetSafe Underground Fence systems?
All the PetSafe underground fence systems we offer have one thing in common: the Deluxe Radio Fence transmitter (Item #RF1010). The only things that change are (1) the type of receiver (collar) that comes with the transmitter, and (2) whether the system is sold with boundary wire and flags. For a first-time owner, obviously it would be best to buy a full kit, containing a transmitter, receiver, AC adaptor, boundary wire, and flags. The amount of wire and flags you buy will depend upon the size of the area you want to contain. See also the FAQ about Above-Ground Installation to see if that would be best for you. If so, keep in mind that you will need to purchase sod staples for installation.
