Take a blade of grass and touch the fence with it a couple of on inches from your fingers and slowly move your hand closer while keeping the grass on the wire. You should feel it at about an inch to an inch and a half from the wire.
That's exactly the way I used to test um !!!!!
The fencer I got now will hurt you, if you touch the grass to the wire just an inch from your hand. I can feel it tingle 6-8 inches from the wire and if I'm grounded really good and got a green stem of grass, 12" from the wire.
Monday morning, I finished putting up the electric fencing around the garden spots. Somewhere around 3000' of wire.
