We have now completed the first full Antarctic season using our SeaSPY magnetometer and can report that we are delighted with its performance. It has proved to be very robust and trouble free in operation and has delivered consistently good data. There is no doubt that we chose the right instrument.
Start up
A 1000m SeaSPY magnetometer with electronics module and sensor configuration comes with:
- 50m of tow cable
- Isolation transceiver
- RS-232 cable
- 24V universal AC power supply
- SeaLINK logging and GPS capability software for Windows
- All enclosed in a custom aluminum shipping case
- Leak detector
Basic configuration starts at
$24,975.00USD
SeaSPY is available with many options and accessories. Please contact us to discuss your specific needs.
Crystal clear
SeaSPY’s accuracy is 0.1nT—the highest absolute accuracy of any magnetometer on the market. No matter where you are or in which direction you are surveying, SeaSPY gives you consistent, repeatable data you can trust.
Go-anywhere accuracy
SeaSPY sensors don’t require temperature stabilization, so work in any water instantly, on power up. The clock used in the SeaSPY electronics module is accurate to 1ppm throughout the entire temperature range, so the data will always be accurately time stamped and match up perfectly with base station information.
Rugged
SeaSPY’s custom brass underwater connector supports a tonne of towing force. A PVC nose cone protects it from side impacts, while maintaining a streamlined tow body. We’ve never lost a SeaSPY from the connector – except for the time a customer threw one overboard without connecting it to the cable. While there’s some human error that no mag can account for, this story has a happy ending: he went back a year later and found his SeaSPY in perfect working condition.
Stable data
Because of SeaSPY’s high-accuracy Overhauser technology, the sensor does not display heading error. No matter how the SeaSPY sensor is oriented in the Earth’s magnetic field, successive survey lines taken in opposite directions always match up perfectly.
Takes a licking
Attacked by sharks. Cast adrift. Dragged on the ocean floor. No matter what happens in the field, SeaSPY keeps on working. With its tough exterior, snag-resistant design and shock-mounted sensor, SeaSPY is made to survive anything you can throw at it. And it won’t even hold a grudge.
Sleek
SeaSPY’s towfish housing is smooth and streamlined – only the fins protrude. If something snags or hits the fins, they are designed to break away with no damage to the rest of the unit. Fins are easily field-replicable as spare parts.
Tried and true
After more than a decade in the field, SeaSPY remains the most user-friendly magnetometer around. Its low power consumption, easy integration capabilities, self-diagnostic LED system and maintenance-free sensors make it easy for you to get better data.
Smart
A leak sensor in the towfish, triggered by the smallest drop of water, alerts you to a breach immediately, so you can repair the faulty seal with no damage to the instrument. LED’s on the topside unit give you at-a-glance awareness of your tow system status, and continuous self-diagnostics during sampling ensure erroneous data won’t be interpreted as correct.
Easy to Use
SeaSPY’s low power requirements – 1W standby and 3W maximum – means it will run up to 150 hours on a typical car battery. And SeaSPY easily integrates with side scan sonars and other platforms, with no modifications or additional accessories needed.
Maintenance-free flexibility
All SeaSPY sensors are omnidirectional, maintenance free, and do not require realignment or recalibration. They do not contain any consumable parts, or toxic chemicals. In addition, all SeaSPY sensors are interchangeable, and with a repeatability of 0.01nT between the sensors, they are ideal for multi-sensor applications.
Sunny disposition in any latitude
SeaSPY is equally at home in the arctic as it is in the tropics. Just throw it overboard, and it starts working instantly, on power-up. Wherever you are, your data stays constant—even when the temperature doesn’t.
Absorbant
The SeaSPY towfish is made of ¼” super strong fiberglass, coated with a “bumper” layer of polyurethane for extra shock absorption. The sensor itself is suspended on shock mounts, so even if you drag SeaSPY along the ocean floor, your sensor won’t feel a thing.
Proven Sensitivity Specs
Don’t take our word for it. A world authority belonging to INTERMAGNET has independently tested and confirmed our specifications: 0.01nT/Hz; counter sensitivity is 0.001nT.
Omnidirectional
SeaSPY’s Overhauser sensor has no ‘dead zone’, meaning it will produce great results, regardless of the direction of the ambient magnetic field. You can survey in any direction, anywhere in the world, without worrying about aligning the sensor to the Earth’s field, as you need to do with many competing systems.
