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.  Using more than 15 years of experience in the design and development of time domain electromagnetic (TDEM) systems, Geonics introduced, in 1987, the versatile, digital PROTEM TDEM systems. With a single receiver and three interchangeable transmitters, the modular PROTEM systems cover a full range of applications from shallow environmental and groundwater studies, to deep resistivity soundings and three-component mineral exploration.  From this tradition of research and engineering excellence, Geonics continues to move forward with the development of new, more advanced instrumentation: the recently introduced second generation of the successful EM61 Metal Detector has been recognized by the North American military community as a standard sensor technology for the detection of unexploded ordnance (UXO).  Used extensively throughout the world, in many varied and demanding survey environments, Geonics instrumentation has earned the tested reputation for reliable, cost-effective operation.
