Pet Stop® has a patented battery, designed by Scott Touchton, the previous Chief Engineer of Invisible Fence® and the person who managed the team who invented the original Power Cap® battery for Invisible Fence®. This patented battery is made to meet or exceed industry standards and will cost you less money! You don’t have to worry about costly battery plans, only order the batteries as you need them and save even more money.
Have you lost your R21 receiver or want to add a new puppy to your Invisible Fence®? We have great news for you! We have a compatible receiver for less than half the price of the R21 Invisible Fence® receiver!
This Perimeter ®computerized receiver is actually designed to hold up better to the weather and elements that your dog exposes it to everyday. The Perimeter® receiver is not only smaller and safer for your pet, but is more comfortable for them. It has a low battery indicator light, so that you are not left wondering if the battery has died. There is also a progressive correction option included. Additionally, it is smaller and weighs ½ oz less than the R21. With all these features, it is American made, not China made!
