Optics Designed for Brighter Views
The Nikon PROSTAFF 3S 10×42 Binoculars feature an optical system created from leadandarsenicfree EcoGlass. Multilayer coatings, which provide high light transmittance across the entire visible light spectrum, are applied for bright images. Highreflectivity silveralloy mirror coatings are applied on the mirror surfaces of the prisms for a bright and clear view. This great optic design also sports a wide 63'ba apparent angle of view, which limits disorientation and apparent shake normally associated with large magnification binoculars. This improves the overall experience.
Long Eye Relief
Nikon has manufactured the PROSTAFF 3S 10×42 binoculars, as well as many other of its optics, with a higheyepoint design for long eye relief without vignetting. This provides a clear field of view for everyone, even when the user is wearing eyeglasses. A righteye dioptric adjustment allows for the perfect setup to meet almost any user's need.
Durable and RubberArmored Design
The Nikon PROSTAFF 3S 10×42 is built using a fibreglass reinforced body, making it extremely durable out in the field. This durable body is covered with a rugged rubberarmored coating which is textured to provide a nonslip grip, even in the wettest conditions. The barrels are nitrogen filled and oring sealed rendering the binoculars waterproof and fogproof.
