Featuring a full-sized canister prism and RC mount, the Topcon A7R Prism captures challenging prism shots from vegetation, wetland flag markers, and other blocked views. This device mainly mounts a GPS receiver on top of the prism for an integrated robotic network, real-time GPS coordinates, and GPS rover solution.
Construction stakeout is also done with greater precision with the Topcon A7R Prism mounted invertedly on a prism pole. Its RC-3R side-mount connects at several angles, which accommodates very high or very low vertical angles of transmission.
A regular top mount and a side-mounting option for the RC-3R are additional accessories that come with the Topcon A7R. These are all used to gather precise data even at extremely difficult positions.
