Leica GRZ4 360 Prism

This reflector is recommended for all robotic work performed with a survey pole. The rubber mountings on the top and bottom of the prisms provide protection of the glass if the pole falls over. The reflector is supplied in a padded case for safe transportation. The GRZ4 has an overall pointing accuracy of 5mm. However, when aiming directly at one of the three prisms, indicated by yellow arrows, an accuracy of better than 2mm can be achieved.
