Nikon 7577 Monarch 5 10x42 ATB Premium ED Glass Central Focus Binoculars, Black

Nikon Monarch 5 10x42 with a Carrying Case, Neck Strap, Lens Caps

Built with ED (Extra-low Dispersion) glass lenses, which correct chromatic aberrations across the furthest limits of the visible light range and effectively compensate for color fringing. Even when observing objects that would make chromatic aberration the most apparent – such as adjacent whites and blacks – the images will maintain superior contrast and resolution thanks to the ED glass lenses. 

Multilayer coatings, which provide an even higher light transmittance across the entire visible light spectrum, are applied to all of the lens and prism surfaces that transmit light. This minimizes the loss of light due to reflection, thereby ensuring a more natural, clearer view.

Turn and slide rubber eyecups allow users to adjust for a custom fit, durable rubber armored body for non-slip grip, smooth central focus knob, and nitrogen filled and O-ring sealed for complete waterproof and fogproof performance.
