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 1.5m-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.
