Proven High Sensitivity

Don’t just take our word for it. We put our sensors through rigorous independent testing by a world authority belonging to INTERMAGNET – the global network of observatories, monitoring the Earth’s magnetic field.

We have now completed the first full Antarctic season using our SeaSPY magnetometer and can report that we are delighted with its performance. It has proved to be very robust and trouble free in operation and has delivered consistently good data. There is no doubt that we chose the right instrument.

Unmatched Absolute Accuracy

At 0.1 nT SeaSPY2 is orders of magnitude more accurate than any other mag, ensuring that you always get the best possible data. Excellent accuracy characteristics and unmatched repeatability between sensors also improves the quality of gradiometer data.

No Heading Error

No matter how our sensors are oriented, successive survey lines match up perfectly. You’ll produce better quality magnetic maps and won’t lose what you’re looking for in mismatched survey lines. Heading error is an offset in the mag data caused by changing direction with each survey line.

Survey in Any Direction, Anywhere in The World

There are no limitations with our omnidirectional Overhauser sensors. They will collect good, accurate data anywhere –they don’t have a dead zone. The dead zone is the angular region of magnetometer orientation in which the instrument produces poor or no measurements.

Sleek Design

Since you don’t have to orient our sensors, SeaSPY2 has a sleek design that resists snags and minimizes impacts. The polyurethane coated tail with molded fins acts as a bumper, while creating a stable towing platform.

Works Instantly On Power-Up

SeaSPY2 works instantly on power-up in cold, deep water without requiring warm up. Data collected at –40°C will be identical to data collected at +60°C.

Maintenance Free Overhauser Sensors

Our sensors are omnidirectional, maintenance free, and do not require realignment, or recalibration. Plus they don’t contain any consumable parts, or toxic chemicals.

World’s First Internal Magnetometer AUV Integration

We’ve integrated with the Iver3 and the results are incredible. Please contact Melissa Marlowe for more details: mm@marinemagnetics.com +1 905 479-9727 x230

Integrate With Side Scans, AUVs, ROVs and Gliders

A single tow cable is terminated with everything you need. Modifications to your mag or grad are not required.

Quick Glance Diagnostics

We added an LED to our isolation transceiver to let you know every time the mag takes a reading, if you didn’t connect the system properly and if there is a short. In the case of a short, the transceiver also safely shuts down the output power in micro seconds. If a drop of water gets inside the mag, a leak detector warning sounds providing the operator plenty of time to retrieve it and investigate the cause before the mag is damaged.
