The DUALEM-1S dual-geometry sensor has 1-m separation between its transmitter and dual receivers, so its dual depths of conductivity measurement are 0.5 m and 1.5 m (by the 70-% cumulative-sensitivity standard).  For metal detection, the DUALEM-1S can detect a steel drum at depths beyond 1 m.

Users control the DUALEM-1S through its RS-232 port and supply power through the same connector.  Users typically integrate the NMEA-format measurements with GPS positions on a logger.

The compact size of the DUALEM-1S makes it ideal for towing on a sled for optimum spatial and geophysical resolution, and for integrating with other sensors.
