Product Description

Rugged, lightweight, and stylish, this eight power binocular is perfect for everything from birding, to spectator sports, to hunting and amateur astronomy, for it packs a wealth of high-tech features into its elegantly designed body.

Amazon.com Product Description

The Kowa BD42-8GR High Performance 8x42 millimeter Binoculars (Green) are sporting optics of the highest quality. These high-performance binoculars are built with a rugged construction, and a full set of features, making them perfect for anybody looking for portable magnification, be it for purely recreational uses, or more serious outdoor exploration.

All the lenses and prisms in the BD42-8GR binoculars are manufactured with multi-layered coating, ensuring a bright and clear visual range, while the roof prism has phase correction coating and a highly reflective aluminum coating to ensure sharp images and accurate color reproduction. Through the use of a Bak4 prism these Kowa binoculars are able to give you bright, clear images all the way to the edge of the objective lens. Kowa's BD42-8GR roof prism uses the schmidt-Pechan prism, where one surface of the Pechan prism does not provide total reflection, so they have applied a highly reflective multi-coating of dielectrics, called a C3 coating. This allows for a much higher reflectivity than with coatings of silver or optically-enhanced aluminum, offering a reflectance of 99-percent or higher across the entire visible spectrum of 400 to 700 millimeters. Not only does this increase the brightness and sharpness of the images, but ensures an accurate color reproduction is also achieved. Furthermore, the roof surface of the Schmidt prism is phase coated (phase correction coated) to prevent the loss of contrast and image resolution.

The stylish green housing of the Kowa BD42-8GR is waterproof and filled with dry nitrogen gas to prevent the lens from fogging, which allows these binoculars to be used in the rain and other harsh weather conditions. At the same time, these binoculars feature easy-to-use, twist-up eyecups with a large 18.3-millimeter eye-relief suitable for both eyeglass wearers and non-eyeglass wearers. With easy focusing and a smooth turning focus wheel, and a minimum focusing distance of only six feet, these binoculars can be used for many purposes. The use of an inner focusing mechanism has made it possible for the BD42-8GR binoculars to retain a light, compact design, weighing only 25.75 ounces and measuring only 5 x 2 x 5.75 inches (W x H x D). These binoculars sport an 8x magnification, provide an apparent field of view of 50.4 degrees and 361 feet at 1,000 yards, and are backed by an astounding manufacturer's lifetime of the product warranty.
