Ball Prism System

Ball Prism System for Monitoring, Point Stakeout and Surveying

The Ball Prism System is a high-precision solution for survey control, point stakeout, deformation monitoring, construction layout, and total station surveying. Built around a stainless steel ball prism with a centrally positioned triple prism, the system provides exceptional accuracy and repeatability for monitoring networks, control surveys, industrial alignment, and precision prism target applications.

Designed for surveyors and monitoring professionals, the modular system supports ball prisms, magnetic prism bases, monitoring prisms, centering plates, threaded mounts and stakeout accessories, making it ideal for bridge monitoring, tunnel surveys, geotechnical instrumentation, control point installation, and long-term deformation measurement projects.

Ball Prism System Features

• High-precision 1.5" stainless steel ball prism with centrally positioned triple prism
