Topcon's LN-150 3D Layout Navigator

Layout re-invented

The LN-150 takes you from paper plans and tape measures into digital layout and construction verification workflows. This tool is easy to learn and easy to use, letting you automate and execute layout and construction verification processes for increased productivity, accuracy, and bottom-line savings.

  • Simple upgrade for machine guidance
  • Easy one-button, self-leveling setup
  • Wi-Fi and long-range Bluetooth® instrument communication options
  • Seamless cloud-connected workflows with Autodesk, Bentley, and MAGNET
  • Easy to use with MAGNET or Pocket3D software


With more than 80 years of optical technology innovation behind it, Topcon’s LN-150 layout navigator was engineered for contractors’ specific indoor/outdoor positioning needs.

The layout navigator automatically locks onto the prism for real-time positioning on the go. Built to perform on any project that demands confident, precise 3D positioning at up to a 130m working radius, the LN-150 is a uniquely user-friendly solution for your positioning needs.


Easy data workflows

The LN-150 is optimized for use with MAGNET field, cloud, and office software and includes seamlessly integrated workflows with popular design software, including:

  • Autodesk’s Revit, Navisworks, AutoCAD Civil3D, and BIM 360
  • Bentley's ProjectWise and OpenRoads

With a ruggedized field controller, call up simple point layout or large CAD drawings — right in the palm of your hand, anywhere on the job site. Display the design point or line that needs to be staked out, touch it, and the LN-150 immediately points to the exact location. It can also lock onto a prism and guide you to the next design points. One-person layout has never been this easy.

Field control with MAGNET Construct covers basic layout and verification applications, while MAGNET Field can be used for more advanced applications such as setting jobsite control.

From traditional utility layout, to foundations, electrical, plumbing, walls, ceilings, HVAC, and much more – layout anything on the job site up to 130 m away. Never before has construction layout been so powerfully simple.

3D layout tool

The LN-150 is a compact, self-leveling, easy-to-setup 3D layout tool designed for construction applications. Use the LN-150 in place of traditional methods such as tapes or other layout tools. Compact, rugged and light weight, the LN-150 is ideal for construction layout and as-builts.

Building Information Modeling (BIM)

Maintain coordination throughout your projects. Knowing what was done before and working from the same design plan is critical to keep on schedule and avoid costly collisions. With Topcon BIM solutions, you stay connected to the same design.
