Description

The Geometrics G-858 MagMapper uses  a graphical interface to make survey design and data  acquisition quick and efficient. A "Simple" or “Mapped” Mode uses line numbers and known staked reference points to define the map parameters. Or the user may use the integrated Tallysman TW5310™ GPS for mapping positions automatically. Position information may come from an external GPS, from regularly spaced fiducial marks input by the operator or both. At any time, the user may switch to “profile” mode to observe the last 5 data lines as stacked profiles.
