The GRZ101S-B 360° Prism comes with a durable Nylon Bracket that allows quick, tool‑free attachment to poles, making it an ideal companion for field surveying without the need for additional mounting hardware.

Constructed from six high‑precision mini prisms glued together, the GRZ101S-B 360° Prism ensures full 360° signal reception, so you can obtain reliable measurements from any angle without rotating the target.

Designed without a central stainless steel axis, the GRZ101S-B 360° Prism reduces weight and potential signal blockage, while maintaining excellent structural integrity for everyday use.

Featuring a Swiss constant of +30 mm and a pointing accuracy of ±2.0 mm, the GRZ101S-B 360° Prism delivers consistent, repeatable results for construction layout, machine control, and general surveying tasks.

With a prism height of 56 mm and a large‑size form factor, the GRZ101S-B 360° Prism is supplied without a pole or bubble level (sold separately), giving you the flexibility to pair it with your preferred rover rod and leveling accessories.

GRZ101S-B 360° Prism with Nylon Bracket Applications
The GRZ101S-B 360° Prism is ideal for the following scenarios:

Construction Layout & Staking – Quickly set out building corners, foundation lines, and elevation points with full‑angle visibility, reducing the need to reposition the target.

Machine Control & Grade Checking – Use with robotic total stations for real‑time grading, excavation, and paving operations, ensuring accurate cut/fill data.

Topographic & Boundary Surveys – Capture dense terrain data efficiently in open fields or urban environments, where prism orientation may vary constantly.

As‑Built & Verification Surveys – Verify installed structures against design models; the 360° capability simplifies measurements in tight or cluttered job sites.

Indoor & Tunnel Monitoring – Deploy in confined spaces such as tunnels, parking garages, or plant floors, where manual rotation of traditional prisms is impractical.
