I have the Parmak with a digital readout, not sure of the model. Get AC model, you can put it inside of a outboard boat plastic battery box, cut a hole to see the indicators since they are recommended for interior mounting . It is over 10 jolues and will light your a-- up big time. It has kept the hogs out for about 3-4 years now. I only run it at night with a photoelectic switch. One wire about 6" and another about 14". Plenty of ground rods. I have two units for when one goes out and they do occasionally. Put the other one on and send the other to Parmak who has been excellent about repairing them and also with advice about problems that come up.
It keeps lots of pests out but the deer just jump the fence or dive through the wires hoping they won't get hit. Rabbits jump between the two hot wires. I like mine and it works well for what I want. I would really like to kill any hog that comes up to the wire, but I don't have enough years left to even make a dent in the population.
