Robust Performance in Challenging Environments

Used extensively on mining site traverses where precision is non-negotiable - the 3500m range capability handles our longest shots without degradation. The copper coating on the prism resists environmental contamination better than standard options. Excellent value for demanding commercial applications.

High Performance with Premium Investment

Performance metrics are outstanding for infrastructure projects requiring sub-millimeter accuracy over extended distances. The initial cost is substantial but the precision and durability justify the expense for firms handling critical surveying contracts. Minor deduction for the carrying case design which could be more robust.

Frequently Asked Questions

General

✓ What is the maximum working range of the GPR121M Traverse Kit? ▾

The GPR121M Traverse Kit offers a maximum working range of 3500 meters, making it suitable for long-distance surveying applications and large-scale construction projects requiring precise measurements at extended distances.

✓ Is the GPR121M compatible with all Leica total stations? ▾

The GPR121M Traverse Kit is specifically designed for Leica total stations and utilizes standard Leica interfaces. However, we recommend verifying compatibility with your specific total station model before purchase to ensure optimal performance and functionality.

✓ What level of accuracy does the 2 arcsecond beam deviation provide? ▾

The 2 arcsecond beam deviation specification ensures high-precision measurements suitable for professional surveying applications. This accuracy level translates to approximately 1mm deviation per 100 meters of distance, making it ideal for engineering surveys, construction layout, and geodetic measurements.

✓ What are the advantages of the copper-coated prism design? ▾

The copper-coated prism provides enhanced reflectivity and durability compared to standard prisms. The copper coating improves signal return strength, enables better performance in challenging environmental conditions, and extends the effective working range while maintaining measurement accuracy.

✓ What components are included with the GPR121M Traverse Kit? ▾

The complete GPR121M Traverse Kit includes a copper-coated prism for enhanced reflectivity, a GDF321M tribrach for stable mounting and precise leveling, and a GZR103M optical plummet for accurate point positioning. This comprehensive kit provides all essential components for professional traverse surveying applications.
