Topcon Digital Theodolite DT-200L Series
 Laser Theodolites
Each of the new models is available as a Laser theodolite version. DT-205L, DT-207L and DT-209L have the same specifications as the basic models with the addition of a visible red laser beam coaxial with the optics of the telescope. This Class 2 laser is focused through the telescope ensuring a clearly defined and visible spot at a distance of upto 50 meters.
These laser theodolites are the ideal tools for many construction site alignment tasks and setting out jobs.
