    Achieve higher levels of production with MAGNET Field on-board software

    Part of the MAGNET Solution, MAGNET Field On-board runs directly on the OS total station touch screen. Utilize the on-board USB port to plug a USB flash drive into the side panel for fast file transfer. Or for more traditional transfer, use a USB mini cable and transfer files to MAGNET Office Tools.

    With direct exchange between MAGNET Field On-board and MAGNET Office Tools, you will see an increase in overall productivity.

    All of the total station functions are available directly on-board.  In Survey, there is Topo, X-Section, Find Station, Tape Dimension, and Missing Line.  In Stake, there is Points, Lines, Offsets, Surface, Point in Direction, Curve, Real-Time Roads, Road, Slope, and Linework staking.  Plus many calculation functions like Inverse, Intersection, Curves, Area, Corner Angle, Offsets, Adjust, Traverse, and DTM.
