Leaders in Electromagnetics

“The EM31-MK2 maps geologic variations, groundwater contaminants, or any subsurface feature associated with changes in ground conductivity”


EM34 – 3XL

“Simple-to-operate, cost-effective for the geologist and hydrogeologist alike; applications have been particularly successful for the mapping of deeper groundwater contaminant plumes and for the exploration of potable groundwater resources.”



“A High sensitivity and high resolution time domain metal detector suitable for the detection of both ferrous and non-ferrous metals. Typical target response is a single, sharply defined peak, facilitating quick and accurate determination of location.”


About Geonics Limited

A Canadian-owned company, located in Mississauga , Ontario, Canada, Geonics Limited is a world leader in the design, manufacture and service of electromagnetic geophysical instrumentation.

Incorporated in 1962, Geonics originated with the development of the patented EM16 VLF Receiver, which became an exploration industry standard for ground VLF instrumentation. Equipment manufactured in the early years included surface, fixed wing and helicopter EM systems, primarily for applications in natural resource exploration.

From a commitment to specialize in electromagnetic (EM) methods, Geonics has been able to develop a broad range of unique EM instrumentation for an increasingly diverse range of applications. With the introduction of the EM31 Ground Conductivity Meter in 1976, Geonics began to service industries, such as engineering and the environment, with a particular interest in near-surface characterization. Subsequent development of the EM34-3 and EM38 Ground Conductivity Meters – for relatively deeper and shallower exploration, respectively – expanded the range of application fields to include ground water exploration, agriculture and archaeology.
