Oberwerk Mariner binoculars offer excellent image quality at a moderate price. In fact, SPACE.COM recently reviewed the 8×40 Mariner and named it “Editor’s Choice“ (see video below)! These extra-rugged waterproof binoculars are ideal for birding, hunting, surveillance, astronomy, and of course nautical applications.

They are available in your choice of 8×40 or 10×60 models. The 8.4° 8x40mm has one of the widest field of views 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, extra-rugged nylon padded carrying case, caps, and our premium heavy-duty denim strap.
