Marine Magnetics SeaSPY

The most reliable magnetometer you’ll ever meet. Unfailing data, durable hardware and an easy going disposition make SeaSPY a mag you can count on.

  1. General Details

    The SeaSPY magnetometer product eliminates many of the inherent problems associated with other marine magnetomers such as orientation restrictions, sensor realignment, time and temperture drift and poor absolute accuracy. Marine Magnetic’s SeaSPY magnetometer measures the ambient magnetic field using a specialized branch of nuclear Magnetic Resonance technology, applied specifically to hydrogen nuclei. The SeaSPY sensor is unique in that it is entirely omnidirectional. The amount of signal produced by the sensor is completely independent of magnetic field direction. You never have to orient your sensor, because it is already optimized to work around the World.

    The SeaSPY Towfish includes high sensitivity omnidirectional Overhauser sensor, electronics module containing all of the driving electronics, leak detector, 4 lead weights and SeaLINK data acquisition and GPS logging software for Windows. Also included tow cable, communication transceiver, power supply, altimeter and pressure sensor.
