THIS IS A BOUNDARY PLUS, 10K RECEIVER.   THE ONLY REASON TO BUY THIS IS TO PAIR IT WITH A BOUNDARY PLUS TRANSMITTER SET TO SSP-A MODE, 10K FREQUENCY.  IT WILL NOT BE COMPATIBLE IF IT IS SET TO 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 Microlite Dog Receiver 10k Frequency With A New, Sealed Invisible Fence Brand Battery. And Used Invisible Fence Brand Collar.  You will receive the exact items pictured.

Compatible with Boundary Plus Systems in SSP-A Mode when you set the transmitter to 10k.  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, 10k.  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.
