I'm a wanna be plumber. I know it's not rocket science, but it is very intriguing to me. There are certain things about it that through the ages, medieval and current, have been needed to keep people safe. There is a method to it, and it helps the health our our planet. I did find this quote here
"While many major utility locating services may not recognize dowsing, it turns out water companies have been utilizing dowsing to locate damaged pipes, which is a very routine procedure. Many skilled locators will state that they have used and continue to use it to identify underground pipes and water. Dowsing rods, which can be constructed out of coat hangers, can be used to see if you’re standing on top of a live pipeline. According to several expert locators, it won’t tell you how deep the pipeline is, but it is a reliable approach to find pipes. Skeptics argue that there is no underlying science dowsing, while others argue that intuition is the driving force. Dowsing has been used to discover subsurface water since the Middle Ages, regardless of who you believe, but is it safe?
Despite the lack of scientific proof for its usefulness, many water company providers have admitted to continuing to use water dowsing."
One way to find things underground is by digging everything up. If so, make sure you dig deep enough. It would be a waste of time to only dig so deep and have that nasty pipe just a few inches below where you stop. Pretty mean if you think about it.
I do like that video above where it shakes the plumber. I'm kind of an acoustic guy anyway, and having a listening device to pick up the sounds is interesting. Almost makes me wonder if there is like a song singing back to you as you listen for it.
"I'm here, I'm here............."
