Leica GRZ4 360 Prism

Leica GRZ4 360 Prisma

GRZ4 360º prism is recommended for all work with remote-controlled instruments when the prism is mounted on a plumb bob. The rubber mount at the top and bottom of the prism protects the prism if the plumb bob falls over. The prism is delivered in a padded transport bag. The GRZ4 has full 3D point accuracy of 5.0mm.

However, if aiming directly at any of the six partial prisms, an accuracy better than 2 mm can be achieved. Yellow arrows located on the upper rubber mount make it easy to correctly align the prism.

ATR range of 600 meters. Prism constant +23.1 Shaft height: 86 mm Offset: - 11 mm
