Topcon GPT-8203A robotic prismless total station with 3” angle accuracy. The GPT-8200 series brings to the field some of the most advanced instrument features available today, including:

• Reflectorless measurement up to 1200m, or nearly 4,000ft.
• Advanced reflectorless EDM design with two mode operation
• Completely cable-free operation with wireless RC-2II
• Radio-free optical data communication
• Sophisticated tracking technology without expensive, special prisms
• Innovative Movement Anticipation tracking technology

A GPT-8200 Total station combined with the optional RC-2II FastTrak system is the world's most precise robotic one-person survey system. It provides both radioless, reflectorless distance measurements to 400' and instant lock capability at the press of a button. Topcon's exclusive “Plane Offset Program” is standard for all GPT products, and provides the most accurate method for prismless location of building corners in the industry. This program computes a plane by measuring three (3) random points on a wall or other surface. A user can simply sight another point on the surface and instantly compute the desired point. With the “Topcon Plane Offset Program,” you can measure to the corner of buildings and structures precisely without the hassles of reflectorless measurement off the unwanted structures.
