This document introduces the 360-degree prisms of Leica Geosystems TCA total station, including GRZ4 360-degree prism, GRZ121 360-degree precision prism and GRZ101 360-degree micro prism.
The document provides an overview of the tripod options available for Leica measurement systems. It lists several series such as GST, CTP, and BST, describing their construction materials (wooden or aluminum alloy) and special features like metal tips, wider legs, and corrosion‑resistant finishes.
Detailed information is given for each series, including model numbers (e.g., GST20, GST05, BST001L) and their suitability for precise engineering and level measurements. The leaflet also notes the use of stainless‑steel screws and protective red paint on metal parts to ensure durability in humid environments. This manual is written in Chinese.

| Screw material | Stainless steel to prevent rust |
The wider leg adds weight, which enhances stability during measurements.
