Should add that when I first heard of this I was skeptical, but I was working for the AHTD, surveying, and I got some rods and tried it, while waiting for one call. I was soon convinced that it worked, at least for some people. I have never tried anything but underground lines, water, electric, telephone etc. and the graves. It seems to work for me for everything but graves. I must say that I only tried that for a short time, as this was after my back got bad and walking with my arms extended was uncomfortable. miles
