Why Clients use diviners?
Well water drillers / clients use diviners to look for the best point on a site to drill for water. A site needs to offer access for a drilling rig and a diviner has to find in a half or one acre dwelling site of the precise point where to drill for the vertical borehole to gain access to the water table often hundreds of feet below the land.
Although water tables can span hundreds of acres or square kilometres, the place to start drilling in the narrow span of say half an acre depends on access and parking of the drilling rig. Not close to buildings, or near sceptic tanks or percolation fields, or near to pipes or cables. Usually the ideal spot can be found.
Point of Drilling
The exact point of drilling can be chosen by a diviner using rods, twigs or wires, even crystals suspended on a string to indicate the right spot for access to water often hundreds of feet below the site. Most areas on a site accessible by a drilling rig can still hit the same water table, as water tables often span for miles.
