摘要

A geoelectric mapping unit has conical electrodes (6) in insulated mounts on the outer side of an endless vehicle track (2, 3) moving over the ground (8) so that the feed and potential electrodes touch the ground during each individual measurement and contact slides (9) pressed against the inner surface of the lower track.
