Enhanced reflectivity for reliable measurements quality optical glass delivers bright, clear reflections to improve target visibility and signal . Better reflectivity preserves measurement accuracy in varied and lowlight conditions, useful for longrange surveying. Exact 0mm calibration for seamless data integration Factorycalibrated with a 0mm constant for direct compatibility with total stations and GPR1 GPH1 systems. 0mm calibration reduces manual corrections and eliminates a common source of calculation error, simplifying postprocessing and reporting. Professionalgrade accuracy and consistent performance Precision manufacturing and a round reflector design ensure uniform returns from any angle. Suitable for applications that require repeatable, precision results such as cadastral mapping and engineering layout. Durable construction built for field use Sturdy housing protects optical components from impacts, dust, and environmental exposure while maintaining optical alignment. Designed to withstand demanding construction sites and routine topographic surveys without degrading performance. Practical attributes at a glance Function: reflective target for total stations and compatible surveying instruments. Compatibility: specifically matched to total stations and GPR1 GPH1 systems using a 0mm constant. Material: precision optical glass with robust protective housing. Shape: round design for even reflectivity across viewing angles. Performance: optimized reflectivity for clear signal returns and accurate distance/angle measurement. Use scenarios Cadastral mapping: Place the reflector on boundary points to capture precise coordinates with total stations; 0mm calibration removes the need for offset corrections. Engineering layout: Use during site staking and control point transfer where consistent, angleindependent returns speed up setup and reduce remeasurements. Longrange topographic surveys and construction monitoring: reflectivity and rugged housing provide reliable returns and sustained alignment across extended survey days and rough site conditions. What this solves Reduces measurement errors caused by miscalibration or poor reflectivity. Lowers field rework time by delivering consistent, angleindependent returns. Protects investment in surveying hardware by maintaining optical alignment and component integrity in harsh environments.
