GEM Systems, Inc. products

The most sensitive, commercially available magnetometer is the Potassium magnetometer/gradiometer system. The GSMP-35/25 ground system is the highest sensitivity with the greatest absolute accuracy instrument for subsurface investigations in numerous fields, including, but not limited to, mineral prospecting and exploration, oil & gas exploration, UXO detection and discrimination, and environmental & engineering. The GSMP series of magnetometers have the absolute maximum in data quality – exceeding that of conventional Cesium Magnetometer devices by an order-of-magnitude, or more! Data quality is driven by sensitivity, minimal heading error, high absolute accuracy, no microphony, and overall design. Unlike its cesium magnetometer cousin, Potassium offers a thin spectral line of operation – meaning that there are fewer drop-outs and errors during surveying. In the event of a drop-out, it is easy to spot in Potassium magnetometers unlike cesium magnetometers.

GEM’s Overhauser Magnetometer system is a revolutionary geophysical instrument developed by GEM to offer a rugged, low power, and sensitive alternative to Proton Precession and some other alkali vapour magnetometers. GEM’s GSM-19 (Overhauser) magnetometer is a primary standard in mineral exploration and magnetic observatories. As a standard for magnetic observatories, this system has proven itself – for its high sensitivity, absolute accuracy and long life. Overhauser magnetometers are also used in archaeology, pipeline mapping, UXO detection, and other engineering and environmental applications.

GEM’s advanced Proton Precession magnetometer (GSM-19T) is one of the world’s leading instruments for subsurface investigations and exploration. The Proton system is designed to fit the niche for clients who require a low-cost, yet robust and reliable magnetometer for ground geophysical surveys. This system is an entry-level system for clients who require an advanced system without the higher-order features and benefits of GEM’s Overhauser and Potassium systems.

Ground and Airborne Conductor mapping and Cost Effective Resistivity Solutions. Very Low Frequency Electromagnetics (VLF) is a geophysical ground probing technology that utilizes VLF signals in the 15 to 30 kHz range normally used for communication with submarines. The signal generated is suitable for making geophysical measurements globally.
