Has anyone any experience with dowsing?

I'm not sure about auras, or any water being found. But, I can find sewer, gas, and water lines with ease. I use the coat hanger method explained though out the posts. I was a skeptic too, till I was shown how to do this. It has worked for me "every" time I've tried. It has saved me alot of labor over the years, and money not having to rent excavation equipment.
