Nikon Introduces New MONARCH X Binoculars

February 18, 2009

Nikon Vision Co., Ltd., a subsidiary of Nikon Corporation, is pleased to present the new MONARCH X binoculars, superior models in the globally popular MONARCH series. These new binoculars feature outstanding optical quality further enhanced by a large 45 mm objective diameter and innovative dielectric high-reflective multilayer prism coating.
The O-ring seals and nitrogen gas in the slim body make these binoculars waterproof and fog-free. Rubber coating protects the binocular body and assures a firm and conformable grip. The 8.5x and 10.5x MONARCH X binoculars are available for observing nature such as birds and other animals.
