Product Description

Topcon's GT Series robotic total station is the smallest, lightest, and fastest, robotic total station in the world.  The source of this speed advancement is Topcon patented advanced UltraSonic Motors.  These compact and efficient motors transform sound into energy to power both horizontal and vertical rotation – smooth and fast.  This motor with its advanced gearless design has a turning speed of 180 degrees per second making job completion faster than ever! 

The body of the GT is 30% smaller than Topcon's previous robotic instruments, and with the new motor being substantially lighter, the weight has been reduced to under 10.5 lbs.  In addition to increasing the speed and reducing the weight, the new Ultrasonic motors are free of traditional gears and wearing parts and last four times longer.

The GT series of robotic total stations are a trimmed down, high-performance solution that's ready to impress today, yet still grow with you into tomorrow. You get the efficiency of a single-operator robotic system, the power of long range reflectorless measurements, and the ability to perform as a hybrid positioning solution.  TSshield theft deterrent is also standard.
