The MagElement is the latest addition to the long list of products trusted by professionals worldwide. Now compatible with autonomous platforms, this new magnetometer utilizes the lightweight, low-power MFAM sensor already proven in the Geometrics MagArrow. It combines the features our customers use the most, as well as new capabilities to more easily interface and integrate with autonomous platforms. The MagElement is ideal for any marine magnetic survey, including the UXO investigations, that have proven why our marine magnetometers are so respected in the industry.
Since 1969, Geometrics has been designing magnetometers to meet a wide range of industry needs. This very high-resolution Cesium vapor marine magnetometer is low in cost, small in size, and offers flexibility for professional surveys in shallow or deep water.
Features & Benefits
