Features

The Richest Lineup Ensuring Maximum Job Efficiency at Unparalleled Performance Levels

  • 2.5” – unsurpassed telescope resolving power*
  • IP66 – industry’s highest dust/water protection
  • Absolute encoders
  • Lightweight
  • Standard LR6/AA batteries
  • Up to 170 hours of operating time

 Exclusive Features for the Laser Models

  • 200m (660ft.) – long-range laser pointer
  • 0.4mm@10m – ultra-small beam spot

 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.

■ Laser Pointer to Increase Construction Work Efficiency (Laser models)

The DT laser models feature built-in coaxial laser pointers that maximize construction work efficiency. The applications include:

  • Layout/ Setting-Out
  • Horizontal / Vertical Alignment
  • Leveling
  • Grading
  • Squaring

■ Long-Range Laser with Ultra-Small Beam Spot (Laser models)

The laser beam reaches 200m (660ft.) under indoor or underground conditions. Even under daylight conditions, the beam spot can be recognized at up to 50m (164ft.) away from the instrument. Red laser beam emitted from the objective lens is focused simultaneously with the telescope, meaning that the beam spot size becomes the minimum where you focus.
