The BIG EYE 28×100 ED is designed to meet the most demanding specifications and is capable of withstanding maritime weather. It is useful as a marine binocular, a border guarding instrument, or with other applications where long-range viewing is required.
The BIG EYE 28×100 ED has massive objective lenses, BAK-6 prisms and precision ground, multi-coated optics. Optical quality is extraordinary with true edge-to-edge image clarity. Oversized, individually focusing ocular lenses are set at an angle for comfortable viewing, and have foldable eyecups. The mounted device swivels a full 360° horizontally and 135° vertically. The instrument is nitrogen-filled to prevent fogging. It can also be coupled with one or two NVS 14 series night vision monoculars for night operation.
