The flagship GT Series ultrasonic robotic total station
delivers accurate and productive workflows for highly
demanding survey and construction applications. Lay out or
survey more points precisely and in less time, while
improving quality and consistency. Easy-to-use digital
processes with repeatable accurate results mean less
rework and better-quality control. Built for jobsite
mobility, GT is one professional tool that does it all for
layout, survey and machine guidance.
