The black and white 7x50 Nautic BN Binocular from Minox combines fully multicoated glass elements with an airtight housing and focus-free optics to create a well-equipped tool for marine navigation and observation. To prepare this binocular for use on the water or in the rain, the optical tubes are nitrogen-filled for water and fogproof performance, and the binocular is submersible and buoyant.
Minox's single-ocular focusing system enables focus-free performance that is ideal for intermediate to long-range observations. Objects beyond 23 feet will appear detailed and sharp, without the need to refocus the ocular for views along the horizon. The ocular can also focus on subjects closer than 23 feet without sacrificing image quality or depth of field. This fixed-focus system is functional yet flexible enough to handle almost any application. Its Makrolon polycarbonate housing is impact, temperature and corrosion-resistant for use in all locations and conditions. A black and white non-slip rubber armor, fold-down eyecups, and a threaded tripod mount make the 7x50 Nautic a well-equipped binocular for a wide-range of outdoor adventures.
