Used Topcon GPT-9001A 1 Reflectorless Robotic Total Station

Description

The GPT-9000A robotic total station provides precise reflectorless measurement up to 2,000 meters – more than 6,500 feet (1¼ miles) – and can easily focus on small objects like power lines. The onboard computer, with a bright, full color touch screen display, and faster servo motor technology improve field productivity. The GTS-900A series reflector only instruments are available with the same system components.
