Have you considered getting a dog? Our big (80 pound) lab cross has free run of the property and he's chased off all sorts of things over the years, including a fisher and what we're pretty sure was a bobcat. It would take a while to raise and train a puppy, but if you have space and time, this may be a viable option.
And I fully support the hot wire option, though I further note that if you do get it, you should always unplug it during a storm. When I was a kid, we found pieces of plastic halfway across the barn after our electric fencer exploded (lightning.) Thankfully, the warranty covered it.
