Marine Magnetics is an Ontario designer and manufacturer of marine magnetometers and gradiometers for high-accuracy detection and mapping of ferrous targets and geophysical features in maritime environments.
Operating context
Marine Magnetics supplies magnetic survey instruments and processing tools from Markham. Its portfolio now distinguishes networked Synapse arrays, SeaSPY2 and Explorer Overhauser sensors, corrective base stations and close-in magnetic detection. BOB handles survey planning, acquisition, layback correction and exports; optional BAM turns measurements into total-field and analytic-signal maps for target assessment. EIVA independently lists Synapse as a supported payload for its ScanFish Katria sub-bottom frame, creating a practical integration route alongside separate acoustic imaging and navigation equipment. The buyer must select the sensor, array geometry, navigation and interpretation workflow together: a magnetic anomaly is evidence to investigate, not identification or clearance of explosive ordnance.
Canadian footprint
Marine Magnetics has a documented Canadian operating presence in Markham, Ontario, Canada. Its public organization and capability evidence should be read at that location and national scope only where the cited sources explicitly support it.
Markham, Ontario is the published city-level context for Marine Magnetics. It does not imply a street address or exact facility location.
SeaSPY2 measures scalar total magnetic field using an Overhauser sensor for towed marine surveys. It can be configured as a single sensor or gradiometer and integrated with compatible side-scan sonar systems. Magnetic anomalies help surveyors locate ferrous objects; interpretation and target identification depend on the survey design and complementary evidence.
Evidence of maturity
Commercially marketed magnetometer with vendor-reported side-scan and Iver3 integration heritage.
Commercial availability
Select the towfish housing, sensor sensitivity, cable, altimeter and sonar interface through the manufacturer. The webpage and brochure differ on standard sensitivity; the brochure describes a permit-dependent 0.01 nT option.
Core features
Vendor-specified 0.1 nT absolute accuracy and 0.001 nT resolution
Sampling from 0.1 to 4 Hz across an 18,000–120,000 nT field range
Single-sensor, horizontal and longitudinal gradiometer configurations
Side-scan integration with model-specific interface kit, two-way telemetry and matched power
BOB data acquisition and visualization with optional analysis module
Marine Magnetics's public portfolio could support modular uncrewed or remotely operated maritime workflows when integrated with appropriate acoustic sensors, command systems and operational authorities.
Marine Magnetics's documented capability could supply a distinct sensing, processing, integration, deployment or sustainment layer for a containerized anti-submarine-warfare system; this is an analyst-derived fit, not evidence of a specific procurement role.
Reviewed connections indicate possible relevance based on public evidence. They do not indicate procurement direction, eligibility, endorsement or customer interest.
Questions for a first conversation
01
Which sensor and navigation configuration meets the target size, burial depth and survey-altitude requirement, and how will anomalies be independently classified?
Adds the newer array/integration pathway and a complete survey-to-interpretation workflow.

BOB connects magnetometer and GNSS, supports survey guide grids, layback correction, monitoring and CSV export. Optional BAM analyses total-field and analytic-signal maps, targets and GeoTIFF/GXF outputs. A magnetic anomaly supports target investigation rather than identifying or clearing ordnance by itself.
