SOKKIA DIGITAL THEODOLITE
Common Features for All Models
■ Exclusive Features for the Laser Models 200m (660ft.) – long-range laser pointer
■ Superior Performance and Durability
The Sokkia DT series theodolites feature superior optics, mechanics, advanced absolute encoder systems, and proven automatic compensators. In addition to these essential technologies for angle measurement instruments, the Sokkia DT series boasts the industry's highest IP66 dust and water protection capability to withstand the harshest worksite environments.
■ Power-Saving Technology to Save Battery Costs
Four LR6/AA alkaline batteries provide extra-long operating time from 100 to 170 hours, saving costs for replacement batteries. The DT instruments operate for two to five weeks without changing batteries*. * When used for seven hours a day, five days a week, excluding the use of laser pointers.
