Place the Fence Flasher or the Fence Alert at the end of the fence. One glance will tell you that the fence voltage at that point, and at every point between the energiser and the end of the fence, is in order.
Shows you by means of a flashing light if your fence voltage has fallen too far; visible from up to 1.5 km; two trigger levels; simply clip it on the wire, polywire or polyrope - (no earthing required)
