New! Oberwerk Mariner Series Binoculars are the highest-quality hand-held binoculars we've ever offered. These extra-rugged waterproof mil-spec binoculars are ideal for birding, hunting, surveillance, astronomy, and of course nautical applications.![]()
They are available in your choice of 8x40, 7x50, or 10x60 models. The 8x40mm has 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. The Oberwerk Mariner Series 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.
