Precise and Reliable Automatic Compensator
The B series levels incorporate the most precise and reliable compensator
available in the market today. Four super-high-tensile suspension wires and
magnetic damping system ensure accuracy and stability even when exposed
to temperature changes, vibrations, or shock.

Superior Telescope
The optimally designed telescope provides an exceptionally bright and sharp
view that reduces operator’s eye strain. Ultra-short focus distance of 20 cm
from end of telescope makes it easiest to use in confined spaces. Two-speed
focus knob switches between coarse and fine for even faster operation
(B20).
Quick Collimation
The endless horizontal motion drive screw can be operated with either hand
for fast and easy aiming.
Horizontal Angle Measurement
Horizontal angles can be read in 1°
or 1gon units. The freely rotatable circle
allows any angle reading from zero.
Right angles can be quickly set for
layout and alignment tasks.
Rapid Setup
Sokkia’s B Series fit both domed and
flat head tripods. The circular level can
be seen on a pentaprism or plane mirror
located beside the telescope eyepiece.
Stadia
The stadia lines on the reticle allow
distance measurement to be carried out.
Simply multiply the staff length between
A
B
the top and bottom stadia lines by 100.
Optional Accessoiries
Diagonal Eyepiece DE16 (B20)
Ideal accessory for working on jobsites
where there is little space to move.
Optional Accessoiries
40x Removable Eyepiece EL5 (B20)
Increases the standard 32x magnification
to 40x.
Optional Accessoiries
Diagonal Eyepiece DE22 (B30/B40)
A diagonal eyepiece facilitates work in
tight spots with little space behind the
instrument.
