PRODUCT DETAILS
The BP003C Spherical Monitoring Ball Prism is designed for total station surveying, deformation monitoring, construction measurement, and other precision positioning applications. It combines a 25.4 mm (1 inch) prism with a 38.1 mm (1.5 inch) spherical body for stable and repeatable target positioning.
The stainless steel construction provides good durability and corrosion resistance for field use. Its magnetic base allows quick and secure mounting on suitable steel surfaces. The black prism ring helps identify the prism position and supports accurate centering.
The included CTP01 Centering Tool Pin can be used as an optional positioning aid for more consistent installation. The BP003C is a practical spherical monitoring ball prism for surveyors who need fast setup and reliable target positioning.
