Give your pet even more space to run. With the PetSafe Wireless Pet Containment System Extra Transmitter, you can add up to 1/2 acre to your current containment system. This addition to your system is a perfect fit for larger yards. When added, the additional transmitter's circular signal overlaps with your current transmitter's signal. Where they overlap, the signals cancel out, opening up a new play area for your pet.
This extra wireless fence unit can be used to expand the limits of your existing PIF-300 PetSafe Wireless Instant Fence Pet Containment System. Set up overlapping circular fields to give your pet greater room to roam. Must be used in conjunction with the PetSafe Wireless Instant Fence Pet Containment System, Model PIF-300 (sold separately).
