Dualem-2 The DUALEM-2 is a 2-metre, dual-geometry ground conductivity instrument was designed for high-resolution, near-surface surveys for soil studies, archaeological investigations and geotechnical surveys. The DUALEM-2 has even been successfully used in a specialized base-metal prospecting study, due to its high sensitivity, small size and intrinsic stability. It provides a 3 metre maximum depth of investigation, and implements the dual-geometry patent of Dualem Inc. The complementary nature of dual geometries offers improved resolution of near- surface conductivity and magnetic susceptibility. This instrument also incorporates patented Geosensors calibration technology, which further improves its accuracy and stability. The DUALEM-2 is lightweight, self-contained, fully digital, and yields extremely stable and accurate results in terms of ground conductivity estimates for each of the receiver orientations and its maximum-coupled in-phase response.
