There are three models available in the AT-B line up: the AT-B2, AT-B3 and AT-B4 models, all of which share a common IPX6 environmental rating. 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 not only prevents water penetration, but also deters clouding or condensation inside the telescope.

This AP-8 features an engineer’ s handy automatic level with accuracy of ± 1.5mm in 1km double-run leveling and friction brake for faster operation. Moreover, an endless horizontal drive with control knobs on both sides, water-resistant construction for use under dusty conditions or in light rain, and the option to mount on a flat- or spherical-head tripod all contribute to enhanced operability. Optional diagonal eyepiece lens attachments for use in confined spaces are also available.

Nikon’ s world-renowned optics, which give you brighter, clearer images and an improved minimum focusing distance for working in confined spaces. You’ ll see the difference when you look through a Nikon automatic level. Nikon’ s legendary optics effectively let in more light, resulting in brighter, sharper images so you’ ll see much more detail and less distortion, especially in low-visibility conditions. Better optics help you aim more precisely, and they’ re much easier on your eyes-something you’ ll appreciate on long workdays.
