Product Description

Nikon's 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 8.5x56 offers an amazing 6.6mm exit pupil and 43.6 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. The new ATBs incorporate Nikon's exclusive Eco-Glass (made without the use of arsenic or lead) for all lens and prism elements. Prisms feature phase-correction coatings and high reflection mirror coatings for superior sharpness and resolution. Ergonomic styling, mated with a rubber armored exterior, provides added shock resistance and a firm grip, wet or dry to the 7.8 x 5.7-inch Monarch. Turn and slide rubber eyecups, complemented by long eye relief (19.2mm in the 8.5x56, 17.4mm in the 10x56, 16.3mm in the 12x56), allow the binoculars to be used as comfortably by eyeglass wearers as those with uncorrected vision. A large central focus wheel and adjustable diopter make focus easy to achieve and maintain, even while wearing gloves.

I bought these as a step up replacement from the Monarch 8X42 ATB's.
My wife decided she wanted the old ones which left me with the opportunity to get a new pair. After some debate about going to 10X I settled on these. They are brighter and than the 42's and just a notch more magnification. Size and weight is bigger but still not so much they get heavy for short periods as I use they for birding. They came with front and back covers and appear to be as rugged as the original pair which routinely road in the console box of the car. I have had them for almost a month now and well pleased with my decision to buy them. I rate a excellent value as I think I would have to spend considerable more to do better.Nikon 8.5x56 Monarch ATB Binoculars 7517

Outstanding performance at a price far below the big names. They're a bit heavy but you must expect that with 56mm lenses.
