Here we include methods and techniques capable to measure electrical natural potentials or induced by current injection between two grounded electrodes. This current can be simple DC, stepped DC or low frequency alternative and the coupling with the  terrain is galvanic.
          The key physical parameter of electrical measurements is electrical resistivity, generally related to geological characteristics of terrain.
          We use electrical measurement to reveal targets located at different depths, using classical VES, for depths up to 400 m (using power transmitter) and  ERT to depths up to 70 m. In special situations we can also perform 3D measurements, at a requested level of detail.
          For deeper structures we use EM techniques, more efficient and cost effective.
