Topcon GPT-3100W

GPT-3100W Construction Total Station

Topcon was the first to bring a completely wireless total station to the surveying industry and now, with the GPT-3100W series reflectorless construction total station, Topcon gives you the convenience of wireless technology on the total stations with the longest reflectorless range in their class. The GPT-3100W seriesconstruction total station provides the highest measuring precision available due to its dual-optical design, so you get incredible results every time, in all situations.

GPT-3100W Construction Total Station Series Features:

  • Dual-Optical Design—Reflectorless measuring requires a finely focused beam for pinpoint accuracy. Prisms need a wider pattern to prevent off-center measuring degradation. Topcon’s dual-optical system gives you both for the maximum measuring accuracy all the time. 
  • Precise Pulse-Laser Reflectorless—Topcon’s pulse-laser “ time-of-flight” system eliminates measuring errors caused by the overlapping signals used in phase measuring systems. Accurately measuring corners or through objects such as a chainlink fence is always fast and reliable. 
  • Longest Reflectorless Range—Up to 350m, the longest reflectorless range in its class! Measures up to 3000m with a prism. The dualoptical design allows you the extended range using a class 1 laser— safe for all conditions—making it ideal for use in high-traffic and other heavily populated areas.

Topcon’s GPT-3100W construction total station uses a dual laser optics system, one narrow beam for non-prism functions, and a broader beam when using a prism. This stabilizes the beam over long distances providing accurate measurement, even in adverse atmospheric conditions such as heat shimmer.
