• Suitable for all robotic TPS work performed with a survey pole.
• Large rubber mountings protect the prism.
• Overall 3D pointing accuracy of 5.0mm.
• When aiming on a side marked by a yellow arrow, an accuracy of better than 2.0mm can be achieved.
• ATR range of 600m (2000ft)

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 (<1/4"). However, when aiming directly at one of the three prisms, indicated by yellow arrows, an accuracy of better than 2mm (<1/8") can be achieved.
