Three different improvements in the galvanic method of shallow-depth electrical prospecting need to be made. First, a better definition of the electrode array(s) is needed in order to reduce the apparent anisotropy effect and increase the depth of investigation; the square array is one solution. Second, a resistivity meter that can make measurements very rapidly needs to be built. The rapid decrease of the induced electric field for small electrode distances makes such measurements possible. The authors propose a resistivity meter with an eight ms. measurement time. Thirdly, the electrode-ground contact problem needs to be solved by using a resistivity meter that can endure high contact resistances. As an alternative solution, the authors also propose a new type of electrode: a liquid jet one. These improvements could make the resistivity method very attractive and competitive, and open large future developments for the method. -- AATA
