International Super 5000 Electric Fence Controller

Got this International Super 5000 electric fence controller for sale. It's a low impedance model with a 6 joule output, rated for up to 100 miles of fence. It's definitely seen some use and has some dirt and wear on the casing as you can see in the photos, but these things are built pretty tough. Good if you need to power a large perimeter for livestock. Sold as-is.
