The company has been a leader in providing geophysical instruments for ground surveys based on its Proton, Overhauser, and Potassium sensors and systems. In addition to delivering the highest quality data available from a ground sensor, GEM has also implemented a number of implementations which have affected survey procedures and operations world-wide.
These include the development of the “Walking Mag” – the first magnetometer to provide the operator with the ability to walk continuously while making measurements. This walking mode has increased productivity by 3 to 5 times on the ground since sensor staffs and discrete measurements are no longer required. While this technology has been copied by competitors, GEM remains the originator and developer of the most advanced Walking technologies for magnetometers and gradiometers on the planet today.
