The compensator of AT-B Series incorporates four suspension wires made of super-high-tensile metal, which features minimal thermal expansion coefficient – providing unmatched durability and accuracy.
Horizontal circle for measurement
Horizontal angles can be directly read in 1° or 1 gon units. The free rotation feature allows you to read any angle from zero. The circle is covered for protection against dirt and scratches and the readout window is located below the eyepiece for quick reference.
