Topcon GT-605V Ultrasonic Robotic Total Station

Put the productivity of the flagship Topcon GTV Series to work on every layout and survey task with the Topcon GT-605V. The UltraSonic Direct Drive motors turn at 180° per second, delivering the smoothest and most accurate prism tracking available, so you stay locked on target in challenging conditions.

Tuned for 5" angle accuracy, the GT-605V is built for high-volume construction and survey applications where jobsite throughput matters most. Integrate directly with MAGNET Field, Pocket3D, and BIM workflows, and run as a hybrid positioning solution when combined with GNSS receivers. With a compact form factor that's 30% smaller and lighter than previous robotic models, IP65 dust and water resistance, and a 3-year instrument / 5-year motor warranty, the GT-605V is the reliable workhorse for crews who need to get more done in less time.

Key Features

• UltraSonic Direct Drive Motors: 180° per second turning speed for smooth, quiet, and precise prism tracking.
• UltraTrac™ Prism Tracking: Advanced sensor technology and control algorithms that maintain a rock-solid lock on the prism, with fast reacquisition if line of sight is lost.
• Single-Operator Efficiency: Drastically reduce labor costs by allowing one person to handle layout and survey tasks.
• Compact & Portable: 30% smaller and lighter than previous Topcon robotic series for easier transport and setup.
• Hybrid Positioning Ready: Easily combine with GNSS technology for a versatile, do-it-all measurement system.
• Rugged Construction: IP65-rated protection against dust and driving rain for reliable use in harsh outdoor conditions.
• MAGNET & Topcon Digital Layout Compatible: Easy to use with Topcon MAGNET Field or Topcon Digital Layout software for seamless BIM integration.
