• Warranty: 5 Years

Precise, Reliable Automatic Compensator:

• The B-series levels incorporate the most precise and reliable compensator available in the market today. 
• The technological superiority of the Sokkia automatic levels has been proven since the release of the best-selling B2 model in 1963. 
• Four super-high-tensile suspension wires and magnetic damping system ensure accuracy and stability even when exposed to temperature, vibrations, or shock.

Superior Telescope

• Optimally designed telescope provides exceptionally bright and sharp view that reduces operator’s eye strain.
• Ultra-short focus distance of 20cm (7.9in.) from end of telescope* makes it easiest to use in confined locations.
• Two-speed focus knob switches between coarse and fine for even faster operation (B20).

Quick Collimation:

• Two knobs of endless horizontal motion drives can be operated with either hand for fast and easy aiming

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.

Rapid, Easy Setup

• A domed-head tripod makes setting up faster and easier even on inclined, uneven grounds.
• 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.
