I have been offered a 2 year old Red Snap'r LI30 (low impedance, 30 mile) fence charger for $40, less than half what it would cost new (~$95). The reason it is being sold is the person is moving halfway across the country and doesn't want to bring it along. It's stated specs are 1.8 joules output, and 3 joules of stored energy. According to some test data I found on a Canadian website, the measured guard voltage was 8960V on a clean 3.3mi run of fence, and 3900V on a weedy run. Over a 10 mile run, clean was 5870V, weedy was 3290V. For a 3.3mi run of fence, the shock intensity was listed as being 2.2A @ 0.4J dry, 39A @ 2.5J wet. Over a 10 mile fence run, it was 1.5A @ 0.2J dry, 32.9A @ 2.1J wet. Does this seem like an adequate charger for sheep & goats for 5 acres? The perimeter is already fenced with 5' 2"x4" woven wire. I want to divide the property into 3 or 4 permanent paddocs with HT wire(6 or 7 wire), then have the animals in one or two smaller areas with temporary electric fencing. I may also run a wire along the top and bottom of the perimeter, to deter predators. I know it's not a Gallagher, but for $40 it would be stupid to pass up if it isn't a pile of junk.
