MagElement Marine Magnetometer

MagElement Marine Magnetometer

The MagElement Marine Magnetometer is a compact, high-resolution marine magnetometer designed for professional geophysical survey applications. Built for reliable performance in demanding marine environments, MagElement delivers the sensitivity, flexibility, and integration capability required for modern underwater detection and mapping workflows.

Designed for use with ASVs, AUVs, and marine tow systems, MagElement is ideal for marine magnetic surveys, including UXO investigations, pipeline detection, subsea cable surveys, and underwater object detection.

Built for Autonomous Marine Survey

MagElement is designed to integrate easily with autonomous marine platforms. Its low-power operation, compact size, Ethernet data output, and flexible sensor inputs allow it to be deployed on a wide range of marine survey vehicles.

For larger survey operations, MagElement can also be scaled into multi-sensor configurations, allowing teams to tow an array of up to 16 MagElements using a single tow cable. This helps increase survey coverage and improve efficiency across larger project areas.

High-Resolution Magnetic Detection

The MagElement uses a laser-pumped cesium vapor sensor to deliver high-sensitivity magnetic detection with low noise performance. With configurable sampling up to 1,000 Hz, it provides dense data collection for detailed marine magnetic surveys.

This high-resolution performance helps survey teams detect magnetic anomalies at greater distances, improving productivity and supporting more confident decision-making in the field.

Designed for Professional Survey Applications

Whether used for UXO detection, infrastructure investigation, or underwater object identification, MagElement gives survey professionals a dependable tool for collecting precise magnetic data in marine environments.

Its combination of compact design, deep-water capability, flexible integration, and high sampling performance makes it well suited for both traditional tow operations and autonomous survey platforms.
