Divining Rods DO work. I have been using them for the last 32 years to find buried pipes, conduits and septic field piping. I use any sort of light, straight metal wire- coat hangers, brazing rods, TIG wire... Just bend two pieces into "L"'s with the short legs being about 8" long, and the long legs on the order of 18" to 24". Hold the short legs loosely in your hands so the long legs point straight out in front of you and are approximately level. Start walking in the area where you want to locate buried lines. When you cross the buried lines, the long legs of the rods will swing. They will swing about 90 degrees, so they are, in effect, "blocking your path". Mark the spot this happened. Keep walking in a lazy "S" course and you will be able to extablish a series of points. That is where the buried line is routed. I do this routinely and will take bets on the accuracy of divining rods.
My intorduction to divining rods came on my first job out of engineering school in 1972. It was a construction site to add some oil tank farm capacity and some peaking units at a big existing coal fired power plant. The routing of some new underground fire protection and fuel oil piping had to cross a road on the power project. The power company had warned us that there were numerous telephone cables under that road. They told us that if these were damaged, it would likely shut down the 1300 Mw powerplant since these phone lines handled signals for protective relaying and similar between the powerplant and the high voltage switchyard and some distant substations. The construction project superintendent was my boss. He was an oldtimer, raised on a Texas sharecropper's farm, who claimed he did not get shoes until he went into the service. He looked at me and said: "Joe-boy: d'you believe ?" As a brand-new young engineer, I didn;t ask the project super what I was supposed to believ ein, just said: "Yessir, I believe". With that, he told me to go to the operating engineer master mechanic and get a couple of thin uncoated brazing rods. I did just that and hot footed it back to our office trailer. The old Porject Super bent the two rods into "L"'s and took a can of surveyor's spray paint. We went to the area of the jobsite where we were thinking of excavating accorss the road. The old super took the two brazing rods and began walking in a kind of zig-zag course along the road. Every so often, those rods would swing out and twitch. He'd stop and say: "Joe-boy: didya see that ? Mark the spot." I would paint a dot of orange surveyor's paint on the pavement. Soon, we had a few lines corssing the road and knew where we could not excavate. After about 40 minutes, we had a couple of areas where the divining rods showed things to be clear of any buried lines. Then, the old project super put the rods into my hands and told me to shut my eyes and start walking down the road. I felt the rods twitch and pull and could feel them swing until they touched my chest. I stopped walking. The project super told me to open my eyes. I was standing with the rods swung out on the line he had divined a few minutes preciously. The project super told me I had it, obviously did believe, and would be OK to use divining rods to locate underground lines and conduits. I tried a few more wlakings up and down the road with my eyes closed and the rods twitched and swung and confirmed what the project super had previously spotted. I told the project super that I believed.
We asked the resident engineer from the power company to come take a look. He did and had complete doubts as to the use of divining rods. He told us not to do anything until he got someone on site with proper instrumentation to trace signals and locate the phone lines. The power company called in some technician from the phone company. The guy arrived with some electronic instruments and went to work. He marked the pavement with spray paint to indicate where the lines were. His locations differed widely form what the divining rods had showed us.
He and the engineer from the power company indicated a location for us to start excavating. The old project super had no faith whatsoever in the electronic locating instruments. His faith in his divining rods was so unshakable that he had me get a backhoe with an operating engineer to stand by to dig a test hole as soon as the technician with the locator instruments gave us a location. As soon as we got the location from the technician and the power company engineer OK'd it, the old Project Super muttered a few choice things to me and told the operating engineer to take a backhoe and did a test hole on the shoulder of the road. The operating engineer grinned and fired up the backhoe. The old project super looked at me and asked again: "Joe boy, d'you believe ?" I said I did, and he told me to watch the show. The backhoe dug down about four feet and all hell broke loose. Up came the bucket of the backhoe with a hunk of phone cable, all frazzled out so umpteen pairs of conductors stuck out. A tremendous noise was coming from the powerplant. It was the lifting of many safety valves on a 650 megawatt boiler. Safeties on the steam drum and reheater had lifted. The boiler ran at 3200 psig, so the noise of the steam blowing off was not to be believed. The backhoe had just dug up a phone cable which handled the protective relaying between the powerplant and its switchyard. The severing of that phone cable tripped the one running generating unit in the plant off line.
The project super looked at me and grinned, then told the utility engineer and the technician they were full of s--t, their instrument wasn't worth s--t, and the whole matter of a forced outage on a 650 megawatt unit and all the mess that was going cause (and cost) was on their heads. He then told the operating engineer to take the backhoe and dig where we had determined the area to be clear of underground lines by the use of the divining rods. We got a clean hole without hitting any buried lines of any sort. I have been a believer in divining rods ever since.
I use the divining rods routinely when doing home inspections for prospective buyers. With the rods, I locate buried well heads, waterlines between the well head and the house, and locate the spetic tanks and leach fields. Digging around will invariably prove the accuracy of the divining rods. Sometimes, a home buyer wants the septic tank located and pumped. SOmetimes it is the location of a buried wellhead. I will take bets anytime I use the divining rods unless there are overhead power distribution lines. The fields associated with overhead power distribution lines can mess up the accuracy of divining rods.
I use them occasionally at the powerplant where I work to locate buried lines as well. Up at the plant, most people tend to believe in the divining rods as well as dowsing. Around here, local people often will have a site "witched" to determine the best spot to drill a well. That is true dowsing, done with a forked stick. I have seen it done and tried it, but don;t get as good a pull or indication as I do with the divining rods. Friends who are proven dowsers have put the dowsing stick into our son's hands. He has it- I have seen him hold a forked stick in as strong a grip as he can get on it, walk accross a site, and have the stick twist until it nearly breaks. When older dowsers walk over the same spot, the result is the same. I can offer some possible explanation for the divining rods response to buried lines, but have no explanation for the dowsing stick. Meanwhile, out in the cab of my pickup, there is a set of bent pieces of 1/16" diameter TIG wire- divining rods- ready for action.
