The AgriOtter Energizer powers a fence line to keep pets and livestock corralled while preventing predators from accessing your land. Connected to AC power, it electrifies up to 10 miles of single-strand wire and is designed to work in heavily weeded areas. Low-impedance technology permits increased joules on the fence line, enabling current to press through vegetation and weeds to keep the fence energized. It can be used with all wire types, including poly wire, poly tape or poly rope.
