Survey
The trigger key, or measuring distance key, helps you perform topography quickly
while continuously viewing through the telescope. Also, the long distance
working time.
Topographic Survey
Adjust and correct closure errors for latitudes, departures, angles
and/or elevations directly from the MAGNET Field onboard software.
Traverse Adjustment
Quickly and easily calculate areas with the Area function. Determine the center
point for objects such as a columns or electrical poles which cannot be directly
