Geometrics G-882 Gradiometer

Geometrics’ model G-882TVG Transverse Gradiometer system is an advanced integrated magnetometer system providing unmatched versatility and performance. It has a 1.5 m-wide sensor separation for maximum target detection efficiency and survey cost-effectiveness.

The system’s high performance is excellent for the detection and delineation of cables, pipelines, and environmental, archaeological, or military UXO and EOD targets. Objects as small as a 5-inch screwdriver are readily detected provided that the sensor is close to the seafloor and within practical detection range.
