Topcon Construction Total Station made for the Building Trades

If you work in the building construction trades, this easy to use total station is designed for you and the work you do. Set out your design from a digital file on the tablet, with real time visual guidance to ensure your work is accurate to within millimetres. No more tape measures, no more stringlines, no more rework!

Simply power on the instrument and it will self level so you’re ready to work in seconds.

Use your wireless controller to call up simple point layout or large, complex CAD drawings in the palm of your hand, anywhere on site.

Reduce your dependence on surveyors needing to check every bolt hole – check the work before any concrete is poured and make your life and the job a lot easier.

One person set out has never been this easy!

Display the design point or line that you need, touch it on your controller, 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.
