Product overview This precision tribrach optical plummet rotating adapter assembly is designed for precision surveying applications. It combines a stable tribrach interface with a rotating adapter and an optical plummet to simplify instrument setup, improve centering accuracy, and speed field work. Compatible with GRZ2, GRZ3, GDF321, GDF322 models. Key benefits Accurate centering: Integrated optical plummet provides reliable lineofsight centering over survey marks, reducing setup error and rework. Stable and repeatable mounting: Solid tribrach interface and rotating adapter maintain instrument alignment during rotation and instrument changes. Faster setup and instrument exchange: Quick, secure attachment to the tripod and instrument reduces equipment swapping time on site. Improved alignment control: Smooth rotation with positive indexing helps with precise orientation and angle measurements during layout and control tasks. Built for field use: Precisionmachined metal components and a protective finish provide durability and consistent performance in typical surveying environments. Primary features Function: Optical plummet integrated into a rotating tribrach adapter for precise centering and orientation of surveying instruments. Compatibility: Designed for use with GRZ2, GRZ3, GDF321, GDF322 compatible tribrach interfaces and instruments that accept these models. Construction: Precisionmachined components and robust assembly to support stable instrument mounting and repeated field use. Performance: centering accuracy and stable rotation suitable for control staking, alignment and geodetic observations. Usability: Straightforward attachment and rotation control allow quick setup, repeatable positioning, and secure locking during measurement. Practical applications Establishing control points and benchmarks: Use the optical plummet and rotating adapter to center instruments precisely over survey marks when creating or extending a control network. Construction layout and alignment: Maintain accurate instrument orientation and repeatable rotation while staking foundations, utilities, or structural elements. Baseline surveys and geodetic observations: Swap instruments or rotate the assembly between setups without losing centering accuracy, streamlining multistation surveys. What customers will gain Consistent, repeatable centering for improved survey reliability. Reduced field setup time and fewer instrument handling errors. Durable assembly that supports precise measurement tasks in routine surveying work. Compatibility note Intended for use with instruments or tribrachs accepting GRZ2, GRZ3, GDF321, GDF322 interfaces.
