About the GEM Systems GSM-19T Proton Precession Magnetometer/Gradiometer
The GSM-19T is GEM Systems' proton precession instrument, distinguished by three built-in data-acquisition modes — Walking, Mobile, and Base Station — large on-board memory, and an integrated high-resolution GPS receiver, all housed in a single field-rugged console.
It is positioned as an accessible, robust entry point into magnetic surveying for mineral exploration, groundwater, and general geophysical investigation, and remains one of the most widely used proton-precession systems in the field.
