The first time you see it, you know it’s unlike anything you’ve experienced before. Everything about the LN-150, from the advanced technology inside, to its clean and innovative design, is a game changer for layout. With Topcon time-proven and robotic total station technologies, the instrument offers a totally new tool that’s easy to use, without sacrificing the accuracy and versatility needed for all types of construction layout.

With the press of just one button, the LN-150 automatically self-levels and is ready for action. Pair it with a hand-held, touchschreen controller and you are ready to go to work.

With a ruggedized field controller, call up a 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, then 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.


From traditional utility layout, to foundations, electrical, plumbing, walls, ceilings, HVAC, and much more – layout anything on the job site up to 130 m from the LN-150. Never before has construction layout been so powerfully simple
