When extreme low light performance is critical, nothing can compare to a set of really large objective lenses on a hunting binocular - unless it's that big glass on a Nikon Monarch ATB. For nearly a decade, Nikon's ATB (All Terrain Binocular) line has earned a reputation among serious hunters for superb optics, incredible ruggedness and extraordinary value. For 2006, Nikon furthers that reputation with the introduction of a new 56mm objective Monarch ATB that possesses the same features and specifications as its popular 42mm brethren - but offers the largest objective lens in Nikon's roof prism binocular line-up.
The objective lens size of the new 56mm Monarch also translates into an exit pupil designed to enhance low light performance. Nikon's 10x56 offers an amazing 5.6mm exit pupil and 31.4 relative brightness index. As with the entire Nikon Monarch family, the new 56mm Monarch ATB line is fully waterproof and fogproof and features fully multicoated lenses for maximum light transmission and image quality.
