Nikon Action Extreme binoculars feature an all-metal chassis with lens fittings housed in a tough, lightweight polycarbonate body shell. The EX is nitrogen filled and O-ring sealed for total waterproof and fog proof performance in any environment. Its body is ergonomically shaped, tripod adaptable and rubber coated for a non-slip grip, wet or dry. The 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.
