About the Marine Magnetics SeaSPY2 Marine Magnetometer
The SeaSPY2 is a towed marine magnetometer using a maintenance-free Overhauser sensor that requires no ambient-field calibration and operates effectively regardless of towfish orientation — a practical advantage in rough sea states. It weighs roughly 12 kg in air (about 4 kg in water) and integrates with side-scan sonar and AUV platforms.
Its accuracy and orientation independence have made it a standard choice for offshore UXO clearance ahead of cable and pipeline installation, wind-farm site surveys, and marine archaeological investigation.
