Cost-efficient measurement with absolute reliability – industrial theodolites and laser stations meet the highest standards even under tough conditions. Laser Theodolites have long since been the standard in the optical compensation of satellites and navigation systems and head-up displays in aircraft. Compactly built for precision, speed and durability the ET/ETL series Laser Theodolite offers many advantages over conventional Electronic Theodolites Unlike the conventional Electronic Theodolite, which requires you to sight or focus through the eyepiece, the integrated laser beam sights and measures to a specific point. This allows for ultra precise, to-the-point measurements. Because the Laser Beam and Telescope swivel simultaneously all you have to do is to point, focus and mark.
