Tempo Communications 508S-G Cable and Wire Locator - Locate Wires Behind Walls (Latest Model)

I tried this product a couple of times and could not get it to work the way the instructions described. Tried finding circuits on breakers and the tone was not right. Maybe doing something wrong.

This worked well for tracing wires in walls. The receiver seems to be fairly directional, and aiming it helped narrow down the location of the wire better than just moving closer and further. The molded plastic case holds everything nicely. The system showed some ghosting and random responses, but I was able to trace the wires.
