Rapid, Stable, andDurable CompensatorThe compensator

o AT-B Series

incorporates our

suspension

wires made o

super-high-tensilemetal that eatures

minimal thermal

expansion coefcient, providing unmatched

durability and accuracy. Finely tuned magnetic

damping system quickly levels and stabilizes

the line o sight despite the fne vibrations

present when working near heavy equipment

or busy roadways.

Horizontal Circle forAngle MeasurementHorizontal angles

can be directly

read in 1 or 1gon

units. Free rotation

eature allows you

to read any angle

rom zero. The

circle is covered

or protection against dirt and scratch. The

readout window is located below the eyepiece

or quick reading.

20cm (7.9 in.) - Ultra-ShortMinimum FocusThe AT-B Series can

ocus on objects at

20cm (7.9 in.) in ront

o the telescope. This

eature dramatically

acilitates the works

in confned spaces.
