EquiFence

27 years fighting with electric fencing for horses and cattle, and all the usual problems ranging from rusting steel wire to soft, sagging aluminum that breaks and shorts out the fence every time a limb falls on it. Gave this a try, thinking it may not provide the needed "incentive" for an animal touching it, because it LOOKS like it's mainly insulation. I accidentally got across some of this during a fix, and it nearly blew my socks off! GREAT product. Very expensive, but given the number of times I've had to remove/fix traditional fencing over the years, this is actually worth it. Sturdy, STIFF, but a solid performer, rust free, sag free, etc. I only fence a little over a mile of pastures, but once installed, it's as worry-free as it gets. As another indicated, if a horse gets run through the fence, it makes it without injuring itself. That alone is worth a lot. It's hard to strip ends, so I use a pipe tubing cutter to cut down to the wire, then pull the cutoff with pliers. Works great. Join ends with one of the several types of fence wire connectors. Also, as said before, I highly recommend either buying or making a spinning jenny, or when you pull wire off the spool it will coil badly and it's really stiff enough that it's hard to straighten out. Also, if you use any kind of stand-off insulators, make sure they are the wide mouth type, because this diameter of this product is too large to fit into the opening of insulators made for regular wire.
