Seek, and ye shall find. Magnetometer technology that helps you do more finding and less seeking.
The SeaSPY towfish is made of ¼” super strong fiberglass coated with a ‘bumper’ layer of polyurethane for extra shock absorption. And the sensor 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 our isolation transceiver can save you hours of frustration. If all your 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 flashes with every mag reading. Customers consistently tell us that these features have saved them countless hours in the field.
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.
Highest Absolute Accuracy, If you want good data you have to start with the most accurate sensor. SeaSPY sensors are orders of magnitude more accurate than any other magnetometer: 0.1nT. The repeatability between SeaSPY sensors is also unmatched at better than 0.01nT. Making them the sensor of choice for
World Wide Operation with No Restrictions
SeaSPY will collect accurate data no matter where you are or in which direction you are surveying. This is not the case with optically pumped magnetometers which have dead zones and must be oriented at a specific angle relative to the earth’s magnetic field. This issue can be particularly problematic in equatorial regions where you cannot collect data in every direction.
Proven Sensitivity Specs
Don’t just take our word for it. We put our sensors under scrutiny, through rigorous independent testing, by a world authority belonging to INTERMAGNET. Intermagnet is the global network of observatories, monitoring the Earth’s magnetic field. The tests confirm our specifications: 0.01nT/ Hz; counter sensitivity is 0.001nT.
SeaSPY is a pulsed Overhauser magnetometer that measures the ambient magnetic field using a specialized branch of nuclear
Magnetic Resonance technology, applied specifically to hydrogen nuclei.
