Also, Spectra Precision Surveying introduced Direct Reflex Geodimeter System 600S DR 200+. The 600S DR200+, for reflectorless measurements with a range of more than 200 m, has a new distance meter based on the pulse measurement principle—the time taken for a very short light pulse to travel to the target and back. It features automatic scanning of a rock face or façade; a corner program to obtain the exact distance to a corner; an intersection program that calculates hidden points; a center point program that automatically calculates the center of objects measured; and a standard deviation program that keys in requested accuracies with a count down feature.
