Portable Magnetometer System MAGWALK

The MagWalk is an ultra lightweight portable magnetometer survey kit to be carried by one person by holding it transversely, longitudinal or upright aside the body.

The kit consists of a two built-in 3-axis fluxgates, a 1-button data logger with internal SD card, rechargeable batteries, an integrated or external GPS, as well as a serial live data output. The MagWalk device is made for small and mid size field surveys.

Combining the MagWalk with the SENSYS Remote Smartphone App allows 2 Hz live readings of all single axes of the sensors as well showing absolute values and graphs for insitu trials / investigations.

The MagDrone DataTool can be used to download and convert the raw data into various formats to make a follow up processing with SENSYS MAGNETO, MATLAB, GIS or other software as easy as possible.
