The Geoscan RM4 resistance meter is mounted on a frame in a twin probe configuration with 0.5m spacing between the mobile probes. Also included is a DL10 data logger. The logger has not been tested by the Group and any recipient would need to provide their own download cables and software to use it, assuming it is in working order. However the meter can still be used without the logger by making a manual note of the readings produced.
Included with the RM4, DL10 and frame are: the two remote probes and their connecting cable (stored on a cable drum), a battery charger, a screwdriver for assembly, and two carrying cases.
