Abstract The author has researched the relation between AB/2 and h of resistivity sounding on shallow investigation by means of contacting between measuring curves on objects and boreholes. The measuring curves on objects assume brokenline form, because their distance of the electrodes should be arranged by regular intermission when measuring on field. The AB/2 of turing points reflecting lower stratum is equal to h, depth of stratum.
