THIS IS A BOUNDARY PLUS, 7K RECEIVER.   THE ONLY REASON TO BUY THIS IS TO PAIR IT WITH A BOUNDARY PLUS TRANSMITTER SET TO SSP-A MODE, 7K FREQUENCY.  IF YOU HAVE ANY QUESTIONS ABOUT THE COMPATIBILITY OF THIS RECEIVER WITH YOUR TRANSMITTER, PLEASE ASK.  I AM HAPPY TO HELP!

Invisible Fence MOD: RIG00-13546 Boundary Plus Dog Receiver 7k Frequency With A New Invisible Fence Brand Collar And A New, Sealed Invisible Fence Brand Battery.  You will receive the exact items pictured.

Compatible with Boundary Plus Systems in SSP-A Mode when you set the transmitter to 7k.  To get the full benefit of this Boundary Plus Receiver you will want to pair it with a Boundary Plus Transmitter in SSP-A Mode, 7k.  There is no reason to spend this kind of money on a receiver like this unless you use it with a Boundary Plus Transmitter in SSP-A mode.

Will ship USPS Ground Advantage Mail.
