New! Oberwerk Mariner Series Binoculars are the highest-quality hand-held binoculars we've ever offered. Oberwerk extra-rugged waterproof mil-spec Oberwerk 8x40 Mariner Series Binoculars are ideal for birding, hunting, surveillance, astronomy, and of course nautical applications.
Oberwerk 8x40 Binoculars have an extra-wide-angle 8.4? field of view. All air-to-glass surfaces are fully broadband multi-coated to decrease light loss due to scattering and reflections, a feature normally found only on binoculars with much higher price tags. Oberwerk 8 x 40 Marine Binoculars feature heavy-duty rubber-armored metal construction, oversize BAK4 prisms with shockproof mountings, extra-rigid and precise center-focuser, right ocular diopter adjustment, twist-up eyecups, brass 1/4-20 tripod adapter threading, caps, and hard case.
