The EM38-4 provides measurement of both the quad-phase (conductivity) and in-phase (magnetic susceptibility) components within four distinct depth ranges, all simultaneously, without any requirement for soil-to-instrument contact. With a maximum effective depth of exploration of 1.5 m, applications in agriculture, archaeology and general soil sciences are common.
The EM38-4 includes four receiver coils, separated by 1 m, 0.88 m, 0.75 m and 0.5 m from the transmitter, providing data from effective depth ranges of 1.5 m, 1.3 m, 1.1 m and 0.75 m respectively when positioned in the vertical dipole orientation, and 0.75 m, 0.66 m, 0.57 m and 0.37 m respectively when in the horizontal dipole orientation.
Data from multiple depth ranges supports a more complete characterization of the soil profile through inverse modelling of data.
Geonics suspended trading in 2026 and by July 2026 their position was still uncertain. For new purchases, DualEM are recommended. We are willing to set DualEM products up in high efficacy towing arrangments in our Dubbo fibreglass fabrication facility and to equip with telemetry for remote monitoring and processing. In this way they can be fitted to farm vectors such as robotic sprayers and traveling irrigators for repeat pass survey able to resovle changes in soil moisture profile.
