Oberwerk Mariner binoculars offer excellent image quality at a moderate price. In fact, SPACE.COM reviewed the 8×40 Mariner and named it “Editor’s Choice”! 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 and 7×50 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.

    I purchased 7×50 mariner in 2015. I find these to be unusually versatile. The optics are sharp, bright, and have worked very well in sailing, general astronomy, sports, and hiking applications. They have a solid, rugged feel yet are easily packed in a range of weather. Happy customer!

    I wanted a handheld multipurpose binocular that could be used in the daytime for reading clock dial gauges on top of vertical above ground gasoline storage tanks and at night for learning the night sky. The Oberwerk 7x50mm binocular was the perfect choice for me. I’m impressed by their quality and how clear they are to look thru. I’m very pleased with my purchase!

    I bought the Oberwerk 7×50 Mariner mostly for moon and star gazing. I find that they also perform wonderfully in low light situations for observing wildlife. The collimation is perfect and the images are bright and clear. I am very pleased with their value and recommend them highly.
