Working Range +/-15 Feet Product Description The Sokkia B40A automatic level incorporate field-proven precise and reliable compensate for accuracy you can rely upon. The optimally designed telescope provides exceptionally bright and sharp view that reduces operator’s eyestrain. Quick acclimation and horizontal angle measurement combine for fast and easy aiming of layout and alignment tasks. Key Features of Sokkia B40A Automatic Level: Rapid, Stable, and Durable Compensate: The compensate of Sokkia B40A Optical Level incorporates four suspension wires made of super-high-tensile metal that features minimal thermal expansion coefficient, providing unmatched durability and accuracy. Finely tuned magnetic damping system quickly levels and stabilizes the line of sight despite the fine vibrations present when working near heavy equipment or busy roadways. 20cm (7.9 in.) – Ultra-Short Minimum Focus: Sokkia Auto Level B40A can focus on objects at 20cm (7.9 in.) in front of the telescope. This feature dramatically facilitates the works in confined spaces. Horizontal Circle for Angle Measurement: Horizontal angles can be directly read in 1° or 1 gon units. Free rotation feature allows you to read any angle from zero.
