  • Longer battery powering duration
    Longer battery powering durations using alkaline batteries. Continuous angle measurement for 150 hours (DT-213). Laser continuous angle measurement for 45 hours.
  • Absolute encoder is used
    Detection of 0 position is no longer needed. Stable, high-accuracy measurement.
  • Laser pointer
    The laser pointer is injected in collimation direction by simply operating one switch. Workers can perform work without guidance by observation personnel.
  • Excellent waterproof structure
    The theodolite body is guarded against a sudden torrential rain and dirt. The theodolite can be used reliably at work sites under severe conditions.
