Nikon Action EX Extreme 8x40 Waterproof & Fogproof BinocularUSA WARRANTY

Not Available.
Condition: Brand new, USA Warranty

Nikon's Action EX, Extreme All Terrain Binoculars are designed to appeal to optics users who value tough construction and reliable optical performance under even the most extreme conditions.

The Nikon Extreme binoculars feature an all-metal chassis with lens fittings housed in a tough, lightweight polycarbonate body shell. Like all Nikon All Terrain Binoculars, the EX is nitrogen-filled and O-ring sealed for total waterproof, fogproof and shockproof performance in any environment. The binocular is ergonomically shaped, tripod adaptable and rubber coated for a non-slip grip, whether wet or dry.

The new Extreme ATB offerings utilize high-resolution lenses and prism systems crafted from Nikon's exclusive Eco-Glass, which is made without the use of arsenic or lead. This lens system provides an extremely clear, distortion-free image over the entire field of view. The lens elements each incorporate multi-layered anti-reflective coatings formulated to deliver optimum brightness, high contrast, true color rendition and flare-free viewing in most lighting conditions.

The Action EX series binoculars each feature a unique, click-stop eyecup design that not only delivers long eye relief, but also allows for variable eye relief that is customizable to the user's own eyes and eyeglasses. The binoculars are central focus with a diopter control to correct for normal right/left eye vision imbalance.

Each model is covered by Nikon's 25-year Limited Warranty, as well as Nikon's exclusive No Fault Repair/Replacement Policy.
