Hi all. I live out in the country and couldn't have a garden if I didn't have a 4' fence with a solar charger on it, since we have so many wildlife out here. I've always used an American Farm 5 mile solar fence. I've had to replace it once. I'm wondering.......does anyone know if it would be better to just get the 2 miles version? I guess I thought the 5 mile one would be better...but I've read that it can need more energy than necessary. Any ideas? I'm in the process of trying to figure out if my Gallagher fence tester is bad, or if it's my charger. Thanks!
