The GoWin is the layout and measuring tool designed and built specifi cally 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.
