BEST value for image quality. Slight flare around the image edges but compared to Leica or Swarovski ($1000 plus ), this is a real bargain.

Diopter has a click lock and would not work itself lose

1 agrees

Yes both Leica and Swarovski shows no internal reflections.But their prices are like 2x to 3x of Monarch ATB

1 agrees

comfortable for long use. Just the correct balance of weight and size

10 x 42 is best balance for birding.

Big, heavy, not very compact. But not enormously sized.

The Monarch ATB 10x42s are a pair of mid-priced binoculars from Nikon. The Monarch ATB 10x42s' dielectric high-reflective multilayer prism coating recreates almost the same brightness as that seen by the naked eye. This coating also recreates high-contrast images with accurate color. Like the closely related Monarch ATB 10x36s, the Monarch ATB 10x42s allow you adjust the fit of the the binoculars with multi-setting click stop eyecups, a feature particularly useful for those who wear eyeglasses. Also like the Monarch ATB 10x36s, the Monarch ATB 10x42s are nitrogen filled and O-ring sealed, which makes them waterproof and fogproof. This and the lightweight design of the Monarch ATB 10x42 binoculars (21.9oz. weight) make them ideal for taking along on your travels. The Monarch ATB 10x42 comes with travel case, lens covers and binocular strap. The Monarch STB 10x42 Team REAL TREE, a model variation of the Monarch ATB 10x42, is also available.
