Datasheet
The Marine Magnetics SeaSpy Marine Magnetometer 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 eld replaceable tailns are the only protruding element and they are designed to snap off should they ever get snagged on rocky outcroppings. The SeaSPY towsh is made of 1⁄4” super strong berglass coated with a ‘bumper’ layer of polyurethane for extra shock absorption. Should even a drop of water penetrate the towsh, 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 shockmounts to ensure the quality of your data isn’t inuenced even if you drag SeaSPY along the sea oor.
