In article [3] describes the traditional method for determining the projections of the underground communications axis (PC) by PC inductive searchers (IPCs) in the "maximum" and "minimum" modes. Working in the "maximum" mode is used for approximate search of a PC, therefore in the following we consider only work in the "minimum" mode.
