Excellent performance under any condition
Get outstanding precision for all your leveling tasks. The B-series levels incorporate the most accurate and reliable compensator available in the market today.
- Tough, compact bodies sealed a against water, humidity, and dust
- Quick setup, easy sighting and superior durability against shock and vibration
- Exceptionally bright and sharp view
Precise, reliable automatic compensator
Four super-high-tensile suspension wires and a magnetic damping system ensure accuracy and stability even when exposed to temperature changes,vibrations,or shock.
Advanced telescope
The outstanding design of the telescope provides an exceptionally bright and sharp view that reduces operators eye strain. Ultra-short focus distance of 20 cm from end of telescope* makes it easy to use in confined locations. Two-speed focus knob (B20) switches between coarse and fine for even faster operation.
Stadia
Stadia lines on the reticle allow distance measurements. Simply multiply the staff length between the top and bottom stadia lines by 100.
Quick collimation
Endless horizontal motion drives can be operated with either hand for fast and easy aiming of layout and alignment tasks.
Horizontal angle measurement
Horizontal angles can be read in 1 ° or 1gon units. Freely rotatable circle allows any angle reading from zero. Right angles can be quickly set for layout and alignment tasks. The readout window is conveniently located on the instrument base -directly below the eyepiece.
Fast, easy setup
A domed-head tripod makes setting up faster and easier even on inclined and uneven ground. The B-series levels also fit flat-head tripods. The circular level can be seen on a pentaprism or plane mirror located beside the telescope eyepiece.

Rapid, Stable, and Durable Compensator
The compensator of B20/B30A/B40A 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
B20/B30A/B40A can focus on objects at 20cm (7.9in.) 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 1gonunits. Free rotation feature allows you to read any angle from zero.
All-Weather Dependability
With the lPX6 rating, the instrument is protected against powerful water jets from all directions, meaning B20/B3OA/B40A withstands a sudden shower or torrential rainfall.
The advanced protection design also deters clouding or condensation inside the telescope.
