Frequently Asked Questions

General
What is the maximum working range of the GPR121M prisms?
The GPR121M traverse prism kit offers an impressive 3500m working range, making it suitable for long-distance measurements and large-scale surveying projects where precision across extended distances is critical.
Is this kit compatible with all Leica total stations?
The GPR121M kit is specifically designed for Leica total stations and maintains compatibility with most Leica instruments. However, we recommend verifying compatibility with your specific total station model to ensure optimal performance and functionality.
What precision level does the 2 arcsecond beam deviation provide?
The 2 arcsecond beam deviation ensures exceptional measurement accuracy, translating to approximately 1mm deviation per 100m distance. This precision level meets professional surveying standards for construction, engineering, and cadastral applications.
What components are included with the dual prism kit?
The dual GPR121M kit includes copper-coated corner cube prisms for enhanced reflectivity, a GDF321M tribrach for stable mounting, and a GZT103M optical plummet for precise centering over survey points, providing a complete traverse prism solution.
Why are the prisms copper-coated?
The copper coating on the corner cube prisms provides superior reflectivity and durability compared to standard silver coatings. This enhances signal strength for longer measurement ranges, improves performance in challenging lighting conditions, and extends the operational lifespan of the prisms.
