Fujinon Polaris 10x70 FMTR-SX Water Resistant Binoculars w/ Field Flattener Lenses, Lens Multicoating, Rubber Coating 16779823

The Fujinon Polaris 10x70 FMTR-SX Binoculars are premier, military-specification Porro prism optics designed for superior astronomical observation, deep-water tracking, and low-light surveillance. This legendary flagship instrument incorporates a proprietary field flattener lens design that actively eliminates edge distortion, delivering perfectly sharp imagery from the center to the absolute boundaries of the wide 5.3-degree view. The massive 70mm objective lenses utilize up to 13 layers of Electron Beam Coating (EBC) to achieve an astounding light transmission rate over 95 percent, providing hyper-bright image contrast in deep-sky or pitch-black naval environments. Built to survive grueling temperature extremes from -20°C to +50°C, the fully sealed aluminum housing is nitrogen-purged and completely waterproof up to two meters deep. Complete with an exceptionally comfortable 23mm of eye relief for spectacle wearers and an individual eyepiece focusing system, this rubber-armored glassing vault isolates your view from ambient shadows to reveal hidden celestial details with unmatched authority.
