For angle measurement, the STS2 offers 2" accuracy. For distance, it delivers 3mm accuracy up to 1000m in reflectorless mode and 2mm accuracy up to 5000m with a single prism, ensuring precision in diverse surveying tasks.
Equipped with dual-side screens and illuminated keyboards, the STS2 allows operators to easily switch sides for faster workflows and reduced repositioning during fieldwork, improving overall efficiency.
Connected via Bluetooth, the STS2 can realize easy measurement and data storage in SingularPad surveying software. Both GNSS and optical survey tasks can be performed smoothly under the same project and datum.
With 16,000 points internal memory, USB export, and software-side storage, the STS2 meets various data needs. Bluetooth ensures seamless connection with SingularPad for smooth data transfer.
Each battery supports up to 8 hours of continuous work. With an additional backup battery included, STS2 ensures reliable full-day operation by allowing quick battery replacement when needed.
Designed for harsh conditions, the STS2 features IP54 dust and water protection and solid construction to withstand demanding environments and ensure consistent performance.
