Simple, one-touch layout for interior building infrastructure, footings and foundations

Topcon’s LN-100 strips away complexity to deliver an easy-to-use tool dedicated to BIM layout. It utilizes Topcon’s time-proven laser and robotic total station technologies to create a totally new tool that’s easy to use, without sacrificing the accuracy and versatility most BIM projects demand. Just press the power button and the LN-100 self-levels. Fire-up its hand-held, touch-screen controller and you are ready to go to work.

The LN-100 creates an entire zone of 3D positioning data.  Simply take the 360 degree prism and smartphone controller anywhere in the layout zone to get precise measurements.  Both horizontal dimensions and vertical elevations are produced anywhere in the layout zone. Additional accessories allow the LN-100 to be mounted on a building column or other out of the way location because there’s no need to stand and look through the lens. The LN-100 follows you automatically.
