The Leica Style GRZ 360-Degree Prism is the ideal tool for all robotic-based work that is being utilized with a surveying pole. It is designed with six prisms joined together to allow the measuring beam to reflect its source from any position on the prism set. This also provides offset and accuracy readings from any side. The operating range is a substantial 2,00 feet with a pointing accuracy of 5 mm. Our prism can be positioned directly on a survey mark with the aid of the built-in point at the height of 78 mm. It attaches easily at the base and is held by a heavy-duty mounting stud. There is rubber affixed to the top and bottom, safeguarding it from falls or being dropped, ensuring the longevity of your prism. As a bonus, with each purchase, you get a padded carrying case and a protective covering for your prism to protect it when not in use. When you invest in our accessory, you can be confident it will provide accurate readings every time.
