Rapid, Stable, and Durable Compensator
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 Circle for Angle Measurement
Horizontal angles can be directly read in 1º or 1gon 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.
30cm (0.3 meters.) - Ultra-Short Minimum Focus
The AT-B Series can focus on objects at 30cm (0.3 meters.) in front of the telescope. This feature dramatically facilitates the works in confined spaces.
- 24x magnification
- 42mm Objective Lens Diameter
- +/- 2.0mm accuracy
