Incorporated in 1962, Geonics Limited is a world leader in the research and development of electromagnetic (EM) geophysical instrumentation. The EM38-MK2 Ground Conductivity Meter, now joined by the new 4-coil EM38-4, has become a highly sought tool of precision agriculture. The EM31-MK2 and the new 8-coil EM31-8 are essentials for environmental and geotechnical site characterization, while the EM34-3 is an invaluable aid to shallow geological mapping for groundwater and other applications and for mapping saltwater intrusion in coastal areas. The EM61 line of metal detectors for UXO and geotechnical surveys now includes the EM61-MK2 cart-mounted unit, the EM61-LX2 person-carried system for difficult areas or small, shallow targets, and with a filter to remove the response to highly magnetic soils, and now the drone-supported EM61-Lite. For rapid coverage of large areas, the EM63Flex Array includes a high-power transmitter and measures full off-time response from up to four coils. The PROTEM and G-TEM time domain electromagnetic (TDEM) systems are exceptional for mineral exploration and for high-resolution resistivity sounding to depths from 5m to 1500m. Based just outside of Toronto, Canada, Geonics Limited has developed a well-deserved reputation for high quality products and unsurpassed customer service.
