You set up to have a ground wire and two live wires when you touch a live wire and the ground wire when walking through the fence you get a big shock no matter what the ground conditions. When the shock passes through your heart it is very unpleasant. I use a small UDAP unit based on a New Zealand charger designed for portable sheep penning. 2 D batteries last 3-4 weeks and I like the unit. It encloses 9x9x9x9 yard space or equivalent.
