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*

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
 * Laser models only

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 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.
