Is using a dowsing rod considered Witchcraft?

Dowsing has been around very nearly forever, and has been (and still is) practiced by many devoutly religious people. There are some who would claim it is Witchcraft, (and persicute those who practice it) and others who would not. There are still many farmers and other ordinary people who dowse for water, in fact, even today, most well drilling companies can put you in touch with a dowser, if they don't have one on staff.
