Petsafe Pif-275-19 Wireless Dog Fence

Originally was purchased as a spare to my system but when I needed it, I discovered it's not the right unit so I'm just reselling it. I have a wired system this is designed for a wireless it is useless to me. My loss, your gain, what you see in the picture is what you get. It was originally in a brand new package but I opened it up to use it. So it's virtually brand new. Other than trying to use it with my system to discover it doesn't work.
