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.

Features of Oberwerk Mariner Series Binoculars:

  • All Oberwerk binoculars are covered by a one year warranty (from date of purchase) for problems due to manufacturing defects
  • All Oberwerk binoculars feature highest-quality BAK4 prisms, which give the best performance across the entire field of view. Competitors often use less-expensive BK-7 prisms, which darkens the image near the edges of the field of view
