The GSM-19T Proton Precession unit is a unique product only available from GEM. It features highly-effective proton energization and physics, three data acquisition modes (Walking, Mobile and Base Station); has a large-volume on-board storage and memory; and comes complete with a high-resolution (0.6 m) integrated GPS – one of the first magnetometers in the world to offer this time-saving, effective technology.
This proven system offers a range of benefits for different applications. In mineral exploration, the GSM-19T has shown itself to be a mainstay of many programs – offering robustness for a demanding environment around the world. In oil and gas exploration, the GSM-19T offers similar benefits. It is also an effective tool in environmental and engineering work for detection of buried drums, utilities and other man-fabricated buried objects.
