     The compensator of AT-B Series 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.

     Horizontal angles can be directly read in 1° or 1 gon units. Free rotation feature allows you to read any angle from zero. The circle is covered for protection against dirt and scratch. The readout window is located below the eyepiece for quick reading.

20cm(7.9 in.) - Short Minimum Focus
     The AT-B Series can focus on objects at 20cm(7.9 in.) in front of the telescope. This feature dramatically facilitates working in confined spaces.
