The all-purpose Trailblazer ATB compact binoculars have multi-coated lenses and offer waterproof and fogproof performance. Ergonomic styling is mated with a rubber-armored exterior, providing added shock resistance and a firm grip whether wet or dry. All lens and prism elements incorporate Nikon-exclusive Eco-Glass made without the use of arsenic or lead. All lenses are coated with multiple layers of anti-reflective compounds for excellent light transmission. Large, central focus wheel and adjustable diopter make focus easy to achieve and maintain, even while wearing gloves. Turn-and-slide rubber eyecups, complemented by long eye relief, allow the binoculars to be used comfortably by eyeglass wearers. Wide field of view makes them great for bird watching, travel, sports spectating and nearly any outdoor adventure.
