Marine Magnetics is the only marine magnetometer company in the world that can produce stable Overhauser sensors that do not degrade with time.
SeaSPY, the product we launched over 10 years ago, was designed to pick up where traditional marine magnetometers left off. Initial research and our sales since then tell the same story: surveyors want a mag they can rely on. SeaSPY’s mandate was to help surveyors save time, money, and energy by taking the realities of working in the field into account.
The SeaSPY connector is a custom brass underwater connector that supports a tonne of towing force. A PVC nose cone protects it from side impacts, while maintaining a streamlined tow body. We have never lost a SeaSPY from the connector, except for the time someone threw one overboard without connecting it to the cable. While there’s some human error no mag can account for, the story has a happy ending: the customer went back a year later and found their SeaSPY in working condition.
SeaSPY’s sleek design resists snags. The inexpensive and field replaceable tailfins are the only protruding element, and they are designed to snap off should they ever get snagged on rocky outcroppings.
The SeaSPY towfish is made of ¼” super strong fiberglass coated with a ‘bumper’ layer of polyurethane for extra shock absorption.
Should even a drop of water penetrate the towfish, a leak detector warning appears on your screen to inform you. Call us overprotective, but in the event of a breach, SeaSPY’s electronics module is encased in a polycarbonate housing with ‘O’ ring seals for another layer of security.
The sensor itself is suspended on shock mounts to ensure the quality of your data isn’t influenced even if you drag SeaSPY along the sea floor. Aquickglanceselfdiagnostic LED system on our isolation transceiver can save you hours of frustration. If all your connections arehookedupproperly,astatus LED will glow green. If there’s a problem with one of the connections, it will glow yellow. If there’s a short somewhere, it will glow red, and the transceiver will safely shut down the output power in microseconds. A blue LED flashes with every mag reading.
