Its rugged metal housing with IP54 protection increases durability on site. The optical system with 20x magnification and 36 mm objective aperture ensures a bright, sharp image of the leveling rod, while the integrated target collimator and built-in compensator simplify setup and fine adjustment.

How to use
Place the instrument on a standard 5/8" tripod and use the three leveling screws to bring the circular vial bubble to the center. Verify rough alignment by looking through the penta prism and, if the vial is level, allow the integrated compensator to perform the fine adjustment. Aim the telescope at the leveling rod using the built-in target collimator and focus with the telescope controls until the crosshairs and rod values are sharp. Perform horizontal alignment using the friction-coupled angular adjustment operated by the side adjusting screws. No power source is required for operation.
Usage recommendations
Store and transport the optical level in its carrying case with locking mechanism to protect the compensator and optical components. Use a compatible tripod (for example BT 160 Professional) and a stable leveling rod for the most accurate results. For tasks requiring higher accuracy or longer ranges, consider the 26x GOL 26 models with increased range and accuracy.
