In designing the High Grade (HG) series of Binoculars, Minox has called upon their vast library of optical experience and merged some of their most innovative technologies with a new elegant build. The Minox High Grade 8.5x43 BR Aspherical Binocular is imbued with Wetzlar Germany's finest engineering and absolutely sparkles with the ultimate in image quality and light transmission as provided by Zeiss' Schott glass. Another highlight is the Minox-designed Quick-Close-Focus (QCF) focusing system that combines rapid, accurate focus and a highly precise distance scale on the center wheel. The M*-coated aspherical glass is housed in a lightweight - yet extremely rugged, sealed magnesium-alloy body enhanced with rubber armor that fits comfortably in the hand.
