MiniMag is one of the most advanced versions of high-precision Overhauser magnetometers on the market. It enables one to measure the modulus of full vector of geomagnetic field with the highest accuracy. The device can be used as a field hand-held magnetometer or stand-alone base magnetic station with a programmable measurement cycle. Automatic coordinate referencing of observation points and time synchronization of the field magnetometer and base magnetic station are provided by the receiver built-in in the GLONASS / GPS console and the MagGPS software.
Distinctive features of the latest generation of MiniMag magnetometers compared with its previous versions:
For fast, convenient and accurate data processing, we recommend the full version of MagGPS software.
