PetSafe Super Receiver PRF-275

The PetSafe Super Receiver is for hard to train dogs that are not affected by PetSafe's regular receivers. It is approximately 3 times as powerful as the regular receivers, adjustable stimulation levels and low battery light. Because of it's size (weighing 4 ounces and measures 2 1/4" x 2" x 1 1/4") and the intensity of the shock, this receiver should only be used on larger dogs. For use with Radio Fence Pet Containment System (not compatible with Instant Fence). The Stubborn Dog Receiver requires a 9 volt battery.
