The Ultimate Total Station GT-1200 Robotic Total Station, 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.
With the GT-1200/GT-600, you get the efficiency of a single-operator robotic system, the power of long-range reflectorless measurements, and the versatility of Hybrid Positioning™, all in your choice of 1”, 2” or 3” GT-1200 models or 2”, 3” or 5” GT-600 models
What's In The Box
Your return on investmentAn MEP contractor saved over $200,000 in labor laying out over 128,000 points for sleeves and inserts over the span of a multiple building project with 109 floors. HPS Mechanical Case Study. The bottom line is that a team equipped with a robotic total station can be five times as fast as team armed only with a set of drawings and a measuring tape
