I had to trace a conduit between the side of the house and a pool equipment pad last year and borrowed one of these from the electrician[Link: techtoolsupply.com]
I was able to follow an obscenely long conduit almost 700 feet with no pull boxes to be found anywhere.
This right here. I used to use one to locate breaks when I installed and serviced invisible fence systems. Works great. Iíve always wondered how one would work in a house to try to locate buried wires.
