Windows® CE is ready in a lightweight, compact body

  • Windows® CE provides a familiar, comfortable operating environment.
  • Completely new onboard application “MAGNETTM Field” is installed as standard feature.

MAGNETTM Field On-Boad Software


Powerful on-board software that covers full functions for surveying and engineering tasks. MAGNET™ Field handles data collection, stake out, roads and coordinate geometry.

Fast and Powerful Reflectorless EDM


  • Fast and accurate pinpointing with phase shift technology.
  • Fast distance measurement of 0.9s regardless of object.
  • Minimum reflectorless measurment distance – just 30cm.
  • Improved collimation with super-bright laser pointer.
  • Smaller EDM beam spot size for minimal distance measuring error.
  • Dependable measuring even at shallow incidence angles.
  • Ensures accurate reflective sheet distance measurement.
  • IP66 dustproof/waterproof performance.

The ultra-narrow EDM beam can precisely measure walls, corners, manholes on the surface, even chain-link fences and tree branches.

LongLink Data Communication*


  • Bluetooth® Class1 communications ensures a long-distance, stable connection.
  • Link between total station and rover-end data collector, both equipped with Bluetooth Class1, facilitates quicksurveying only by sighting the object.

* Option


Advanced Angle Measurement System


  • OS features advanced absolute encoders for long-term reliability in all work conditions.
  • Dual-axis compensation ensures accurate leveling even on rough terrain.
  • Motion clamp and tangent screw ensure stable angle measurement.
  • OS-101 and OS-102 equipped with groundbreaking technology for extremely reliable angle measurement.

Rugged Design


  • IP65 dustproof/waterproof performance Standard usage temperature range -20ºC to +60ºC. Low temperature models can be used in range -30ºC to +50ºC.*

* Low temperature models are available as options.



  • USB Type A and Type miniB port


  • Green/Red Guide Light is built into the telescope as a standard feature, enhancing setting-out work efficiency in a range of 1.3 to 150m.


  • Trigger key lets you take a series of measurements without taking your eye off the telescope. Trigger key is ergonomically placed so that measurement can be taken at any time with just the push of a button.


  • Control panel consists of 10-key pad with alphab etentry with color LCD touch screen display for easy viewing of graphics*.

* Control panel location may vary depending on region or model.


  • Long-lasting battery: one battery provides 20 hours of power.
