I was an unbeliever until I tried it looking for a buried manhole. Back in the 1970s, the office had a sophisticated set of diviners with two bent metal rods which had tubes with bearings for handles. As I passed over the hidden manhole cover, the rods abruptly crossed over. We used them subsequently to trace an ancient culvert which had been lost for years.
