What is Positive-Negative electric fence

The pos-neg electric fence is groundless, in short, this means that the animal does not have to be in contact with the ground to get an electric shock. The two wires of the electric fence are run parallel to each other and the pulse occurs when they are connected. It is important to choose the right distance between the wires so that the animal cannot penetrate between the wires without touching both wires at the same time. Touching the two wires will also cause a very intense impulse because the current is only flowing through a small part of the body at the time.
