FEATURES
Rapid, stable, durable compensator
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. The 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.
All-weather dependability
With the IPX6 rating, the instrument is protected against powerful water jets from all directions, meaning the AT-B Series withstands a sudden shower or torrential rainfall. The advanced protection design also deters clouding or condensation inside the telescope.
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.
20 cm - Short minimum focus
The AT-B Series can focus on objects 20 cm in front of the telescope. This feature dramatically facilitates working in confined spaces.
