DOCTER 7x40 B/GA Details

Docter B/GA 7x40 configuration binocular model is unbreakable and ideal for extreme weather and extreme terrain. Thick rugged rubber armoring with aluminum-magnesium alloy protects construction against impacts, noise and corrosion. Very distinctive design is appealing for any enthusiasts, but would be recommended for more professional use. This model is perfect for marine application, because the 7x magnification gives you enough stability on movable boats without losing too much power. 40 mm objective lens also helps you to see good even during twilight hours. Optically these binoculars perform incredibly well with multi-layered coatings on glass surfaces that helps to enhance light transmission and protects them against scratches on a long run. Images are not only bright, but have a great resolution and sharpness from edge to edge. Special uncovered hinge design makes them very unique and provides the easy handling with better wrap-around grip. They are also filled with nitrogen and equipped with tight seals to make the construction impervious. Focusing is individual for each eye separately, so you don’t have to refocus when looking at different distances. Twist-up eyecups have a special rubber that helps to block away the light from the sides, again very convenient feature for everyone sailing at the great sea.
