Nikon 10x42 Monarch 3 Binoculars offer up Eco glass optics in a rugged yet beautiful waterproof and fogproof polycarbonate housing. Monarch 3 binoculars are a great choice for wildlife observations, travel, sporting events, and more. The killer combination of Nikon’s Eco glass optics, heavy-duty quality build, waterproof/fogproof performance, and a very popular magnification of 10X lets you enjoy bright, high contrast views at any time, and in any weather. A 10x42 pair of binoculars is also easy to hand-hold, but if you choose, the Nikon Monarch 3’s will quickly and easily attach to a tripod.
Nikon’s tried and true Eco glass
Nikon is one of the few optical companies that make their own glass. The high quality glass used in Nikon Monarch 3 binoculars is called Eco glass. It is made without any lead or arsenic, which is better for the environment, but it performs beautifully inside your Monarch 3 binoculars, providing bright, sharp images that are sure to please. The Eco glass lenses are precision aligned and then fully multicoated with phase-correction High Reflective Silver-alloy Prism coatings for good color reproduction and high contrast.
Take your Nikon Monarch 3 binoculars just about anywhere
To truly make Nikon’s Monarch 3 binoculars waterproof and fogproof, they must be placed in a special vacuum chamber and purged of all moisture, air and gaseous water molecules and then filled with nitrogen gas and sealed with O-rings. Nitrogen-purged and sealed binoculars can be exposed to rain, snow, spills, and other liquid contact without worry. In fact, waterproof binoculars also keep out fine particles such as sand and dust. This is a great benefit if you like to go out to the desert or any place that is susceptible to above normal levels of dust.
These Nikon 10x42 Monarch 3 binoculars are not only waterproof, they are fogproof as well. Because water droplets have been purged from the interior and not allowed to re-enter, they will not steam up when subjected to humid or wet conditions, and the growth of fungus will be kept at bay. Fungus can be a real problem for owners of closed optical systems unless they live in the desert or use a dehumidifier religiously. With waterproof Monarch 3 binoculars from Nikon, you don’t have to worry—just go out and have fun!
The Monarch 3 binocular body is sleek and rugged. A quality rubber coating is applied over the lightweight polycarbonate frame, making the binocular easy to grip and hard to drop. Ergonomic curves guide your hands into their proper position for optimum viewing, allowing you to naturally find the focus knob. Rubber lens caps are attached to the binoculars just below the optics so they are super easy to slip on or off. The attached lens caps fold back neatly so they will stay out of your way without misplacing them!
Easy to use, easy to adjust to your unique vision
Not all of us have 20/20 vision, and Nikon took that fact into account when they designed the 10x42 Monarch 3 binoculars. The comfortable and innovative click stop rubber eye cups allow the user to adjust the eye relief to provide a clear field of view, even if he or she is an eyeglass wearer. Fold down the rubber eyecups if you wear glasses, and then adjust the eye cups until they click into the location that allows you to comfortably see the full field of view. This is a fast and easy process, and so even if you share your binoculars with others, changes can be made for each person in just a few seconds.
Dioptric adjustment is easily achieved by turning the knurled ring right below the right eyepiece until it lines up with the correct dioptric number on the index. The central focus knob is also easy to use and is placed in an intuitive position, allowing for natural hand movements to adjust focus quickly and easily as objects get closer or move further away.
