Compact Sophistication The new MONARCH 7 30mm binocular features a new, sophisticated body design that is lighter and more compact. Its improved optical system features 30mm objectives, a wide apparent field of view and Nikon’s ED (Extra-low Dispersion) glass lenses. The sharp, crisp views of the MONARCH 7 are now even more portable and more convenient to take with you on your next adventure. Superior Optical System The MONARCH 7 30mm binocular features Nikon’s legendary ED (Extra-low Dispersion) glass lenses that effectively compensate for chromatic aberrations to provide images of superior contrast and outstanding resolution. Compact Body Design The dimensions of the MONARCH 7 30mm binocular are 4.7 inches long by 4.8 inches wide, making it more portable than ever before. Thanks to a fiberglass-reinforced polycarbonate resin, it’s extremely durable, yet lightweight. Dielectric High-Reflective Multilayer Prism Coatings Applied to all lenses and prism surfaces, this technique provides almost the same brightness as that perceived by the naked eye, and clear high-contrast images that display accurate color reproduction. Turn-and-Slide Rubber Eyecups The turn-and-slide rubber eyecups with multi-setting click stops allow users to adjust the eye-relief for a custom fit - providing a full field of view and maximum comfort during extended periods of use. Fully Multicoated Eco-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. Smooth Central Focus Knob With this simple and intuitive design, bringing objects into focus has never been easier. Waterproof and Fogproof MONARCH 7 binoculars are Nitrogen filled and O-Ring sealed for complete waterproof and fogproof performance.
