GSM-19 GW
The GSM-19 is our mid-range instrument with excellent benefits for subsurface exploration. The Overhauser system offers an order-of-magnitude increase in sensitivity over GEM’s Proton system and matching sensitivities of some alkali devices. With data quality exceeding the standard proton precession, and comparable to the costlier optically pumped cesium magnetometer systems, the GSM-19 is a standard for many applications.
Overhauser magnetometers also provide high absolute accuracy, ruggedness, and reliability – as numerous systems are in operation around the world with an excellent performance record so that the GSM-19 can be counted on in any situation.
