One-touch ease-of-use layout tool

User-friendly solution for layout and navigation on any site

The world’s first 3D positioning system designed for construction layout just got better. 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.

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.

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 more.

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.

Simple, precise layout navigation

By blending our self-leveling laser and robotic total station technologies, Topcon created a new way to perform construction and BIM layout. Simply position and turn on the layout navigator to self-level and connect, automatically.
