Reflective prism for total station and tunnel measurement applications. Designed for quick setup, clear visibility, and long service life when used with plastic survey marks and other survey targets. Key benefits Easy application: simple to attach to plastic survey marks and target mounts, saving time and effort during setup and repositioning. visible reflection: strong reflective effect improves target acquisition and reduces time spent locating points in the field. Purpose built: specifically crafted for use with total stations and tunnel measurement setups to deliver consistent performance in these workflows. Durable construction: made from reliable materials for repeated use and longterm field service. Features and attributes Function: reflector prism for survey and target use with topographic total station equipment. Compatibility: intended for total stations and tunnel measurement systems, and suitable for general surveying and control point marking. Material and build: constructed with durable materials and a plastic survey mark interface for practical field handling. Performance: optimized reflective output for clear returns and reliable targeting under typical surveying conditions. Typical use scenarios Topographic surveying: attach to survey marks for boundary and mapping tasks to speed point collection with a total station. Tunnel measurement and alignment: use as a target during tunnel excavation and monitoring to improve measurement efficiency and accuracy. Construction layout and control points: deploy for temporary or semipermanent control targets on sites where quick setup and durable performance are required. What makes it stand out Combines ease of application, visible reflective performance, and a design focused on total station and tunnel measurement needs to provide a practical, longlasting survey reflector option.
