We just built a horse fence on our acreage using 6 ft posts pounded in to 4 feet and 4 strands of electric rope spaced about 8-10" apart. The rope is very much like the electrobraid, but a little more durable for our dramatic changes in seasonal temperature. It is also quite visible. I have the top and third strand electrified with the second and bottom strand grounded. After only a couple of weeks, the horses know exactly where the fence is. They will reach across to be petted, but are very careful of the top strand. I don't know if this is true or not, but someone told me they can sense the fence is on through their whiskers. At any rate, the fence looks good, was inexpensive to put up, is as safe as any and the horses respect it well.
