New! Oberwerk Mariner 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 8.4° field of view, one of the widest FOV's available from any modern binocular. 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, and hard case.
