This 360° prism reflector has an overall 3D pointing accuracy of 5mm, which can extend to better than 2mm when aiming on a side marked with a yellow arrow. The Leica GRZ4 is suitable for use with all robotic TPS work performed with a survey pole.
The reflector has six joined corner cube prisms, allowing the measuring beam to reflect back to the source from all positions.
