BIG EYE 28x100ED ULTRA LONG-RANGE OBSERVATION BINOCULAR

The BIG EYE 28x100ED is designed to meet the most demanding specifications and is
capable of withstanding extreme maritime weather. It is useful as a marine binocular,
a border-guarding instrument, or for other observational applications where long-range
viewing is required.

The BIG EYE 28x100ED has massive 100mm 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 BIG EYE 28x100ED is nitrogen-filled to prevent
fogging and is supplied with a hard case equipped with a lock. It can also be coupled with
one or two NVS 14 series night vision monoculars for night operation.
