The GEM GSM-19V is a rugged, portable VLF system suitable for geological and environmental surveys. Used for years as a fundamental tool in mapping faults and structures, today, thanks to the ability to measure three stations at a time, it is used in support surveys or combined with magnetometry measurements.
The acquired measurements can be inverted using the VLF2DMF software developed by EMTOMO, which can provide deep resistivity sections.ry 4 seconds.
