The B20-25’s shortest focusing distance of just 0.2 meters allows surveyors to measure elevations even in confined job site areas or near reference benchmarks. Combined with its ±1.5 mm per kilometer double-run accuracy, this optical level delivers outstanding reliability in any leveling application requiring detailed accuracy and consistency.

Easy to Use for Faster Workflow

• Clear, dual-side horizontal circle makes it easy for both left- and right-handed users to take angle measurements.
• Large focusing knob and leveling screws allow quick adjustments with minimal effort.
• Circular level bubble placed on top for enhanced visibility during setup.
• Compatible with standard leveling staffs and tripods using a 5/8″ thread mount.

Maintenance and Storage Recommendations

• Store the instrument in its original carrying case when not in use.
• Use a soft, lint-free cloth to clean the lens after each job.
• Avoid exposing the instrument to sudden temperature changes.
• Periodically check leveling and compensator performance using calibration tools.
• Keep adjustment tools and user manual accessible in the case for field calibration.
