SuperGrad Gradiometers
GEM?s solution for these types of installations is the Potassium SuperGrad. This special gradiometer is a system based on the Optically Pumped Potassium instrument ? a unique technology that was developed in response to the United States Geological Survey?s need for an ultra-high sensitivity magnetic gradiometer.

Gravimeter
Gravimeters are specialized accelerometers used to measure local gravity or variations in the gravitational field of the Earth. High-performance gravimeters and gravity gradiometers are well-suited for applications such as geophysical and geodetic surveying, precision navigation, exploration for natural resources, and underground fluid monitoring. Such sensors may also be useful for identifying special nuclear materials, treaty verification, and void detection.
