Résumé

Application of mobile electrical and electrostatic quadripoles during the past ten years has allowed a considerable increase in the size of the surveyed areas, together with keeping a high spatial resolution and a reduction of the total cost of a survey. Two new developments of towed arrays are illustrated here: (1) a pole-pole array pulled by the operator provides a lightweight solution for mapping large surfaces at a unique given depth of investigation , as shown by the prospection of the Roman-British city of Wroxeter; and (2) a multipole, multidepth system allows a 3-D investigation of the ground resis-tivity, as illustrated by the experiments undertaken on the test site of Garchy and on the archaeological site of Montbaron (Indre, France).
