EDM Instruments:
Geodimeter® System 120—A Better
Total Station Investment
In first-class automatic multi-function EDMs, you
really have a choice <strong>of</strong> two instruments. Theirs is a
stand-alone system, which implies some limitations
on accuracy and flexibility. Ours mounts on your
theodolite (which can be suited to the job at hand),
adapts to its sensitivity and permits plunging the scope.
With the 120, vertical distance and height, horizontal
and slope distances are available at the touch <strong>of</strong> a
switch. The 120 will track a moving reflector at speed
<strong>of</strong> up to 13 fps and will do it in horizontal distance
and height mode.
