One Person Operation
12 kgs (27 lbs) for the mag 7 kgs (15 lbs) for a 50 m (164 ft) tow cable
Proven High Sensitivity
Independently tested by the world authority INTERMAGNET–the global network of observatories, monitoring the Earth’s magnetic field.
Unmatched Absolute Accuracy
0.1 nT accuracy and unmatched repeatability between sensors ensures best possible data.
No Heading Bias
No matter how our sensors are oriented, successive survey lines match up perfectly.
3w Power Requirement
1 car battery = 150 hours of continuous use 2 lantern batteries (26 Ah) = 104 hours of continuous use
Survey in Any Direction, Anywhere in the World
Custom omnidirectional overhauser sensors collects good, accurate data anywhere.
Sleek Stable Design
Resists snags and minimizes impacts. The polyurethane coated tail with molded fins acts as a bumper, while creating a stable towing platform.
Quick Glance Diagnostics
Automatic power supply cutoff, and leak detection give you plenty of time to pull the mag before damage.
Make SeaSPY2 a perfect fit for your application.
