Marine Magnetics Marine Magnetometer Series

Marine Magnetics Marine Magnetometer Series

High precision dead zone detection, defining industry standards

The Marine Magnetics series of marine magnetometers includes two core products: the SeaSPY2 high-performance magnetometer and the Explorer mini magnetometer. This series of products all use industry-leading Overhauser effect sensors, achieving unparalleled absolute accuracy (0.1 nT) and truly global omnidirectional dead zone free operation. The sensor is maintenance free, calibration free, and has no heading deviation, ensuring the consistency and reliability of survey data. SeaSPY2, as an industry benchmark, is suitable for the most demanding deep-sea and AUV integration tasks; Explorer, on the other hand, provides highly sensitive solutions for nearshore, shallow water, and portable applications with its ultimate lightweight design.
