7K is the most common frequency used for Invisible Fences. If your neighbor also has an Invisible Fence, the PIR-003 10K was used in these installations experiencing frequency conflicts with neighboring containment systems. 

Perimeter Technologies, a leading manufacturer of electronic pet fencing, has designed a cost effective alternative to the once exclusive Invisible Fence R21 Fence dog fence collar, providing owners of the nation s largest and best known professionally installed dog fence brand a significant savings on their replacement collar receivers.

Don t be fooled by the low aftermarket price. Perimeter Technologies is a brand you can trust with products that are loaded with exclusive features and benefits not found in the original. As a matter of fact, Perimeter Technologies' President is the same person that founded Invisible Fence brand back in 1976!

Replacement for Invisible Fence collar
I needed a replacement collar for my Invisible Fence. I wasn’t sure if this would be compatible, but it was worth a try since the IF brand replacement collars are $350 with $100 service call. When it arrived, all I had to do was put the batteries in that came in the box, and when I waved it over the invisible fence wire, it immediately activated. I did not have to pair it with the unit In my garage. Could not be happier.

Collar
Collar works perfectly. Needed to change the frequency on system, but worked as advertised after that. Would definitely order from RadioFence again!
