Since 1980 leading the world of magnetics.
GEM Systems Inc. is a world leader in high-precision magnetometers, gradiometers and magnetic sensors for mineral/ oil exploration, environmental, engineering, UXO applications and earthquake research. GEM Systems pioneered the most precise optically pumped potassium magnetometer and the high-speed Overhauser. Ground systems include magnetometers and gradiometers available in walking mode and featuring integrated GPS and optional VLF-EM for shallow resistivity mapping. Airborne systems include magnetometer, VLF sensor(s) and towed bird systems for single sensor and gradiometer (vertical and/ or horizontal configuration) applications. Earth monitoring systems include the dIdD vector magnetometer for measuring precise changes in Earth declination and inclination, and the Super Gradiometer for measuring very subtle gradient field changes. UAV solutions include the ultra-lightweight potassium high-precision UAV magnetometer (DRONEmag™) in addition to the superlightweight Cardinal, AirBIRD, AirGRAD and the new AirVLF (UAV VLF-EM) towed systems. GEM also manufactures a stabilized magnetic field system for experimentation and calibration. Systems are turnkey, reliable, available with various options and configurations and a three-year warranty.
