Eschenbach Optik 4271125 overview

  • 1Description

A compact, lightweight optic with an ergonomic shape for superior handling, the 10x25 Adventure D-Series B Active Binocular by Eschenbach Optik is suited to a wide range of recreational uses. Its BAK4 prisms and fully multi-coated glass assures a bright, clear image with true colors, and the rubber-armored, watertight housing is nitrogen-filled to resist fogging.

The binocular features twist-up eyecups to account for eyeglasses or sunglasses and an adjustable diopter to compensate for eyewear prescriptions. The center-focusing design makes it easy to achieve a tack-sharp image. A tripod mount is provided for the most stable, shake-free viewing experience. The Adventure B Active comes with lens dust covers, a padded strap and a neoprene carry bag. At just 12.9 ounces, you can use this binocular for long stretches without fatigue.
