Marine Magnetics Seaspy Towed Magnetometer

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.

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 1⁄4” super strong fiberglass coated with a ‘bumper’ layer of polyurethane for extra shock absorption. Should even a drop of water penetrate the towfsh, a leak detector warning appears on your screen to inform you. In the event of a breach, the 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.

A quick glance self-diagnostic LED system on the isolation transceiver can save hours of frustration. If all connections are hooked up properly, a status 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 ashes with every mag reading.
