The GoWin is the layout and measuring tool designed and built specifically for construction. It’s expanded keyboard and on-board software allows construction professionals to check grade, topo, set points and perform any number of other layout tasks previously requiring a surveyor. Built to work the way you do, the GoWin comes standard with an RS232 port, perfect for use with Topcon’s FC series field controllers. And the GoWin puts those inaccessible points within reach. As with all Topcon instruments, the GoWin is built to exacting standards, reliable and cost effective, and will provide years of productivity. If you or your crew has ever waited for stakes to be set or replaced, or wished you could quickly determine how much material you’ve moved in a day, then Topcon’s GoWin is for you.

Product Brochure

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