Now that we covered some basics on Monarch 5 binoculars, let’s dig in and see how it performs and how this binocular is made. We’re starting with reviews of the product’s features to give you an in-depth look at Nikon Monarch 5 binocular.

Body and build

The design of the body is very ergonomic, and the binocular fits easily in the hands. In order to save on weight, the body of the Nikon Monarch 5 is made from polycarbonate resin reinforced with glass fiber. It weighs 21.6 ounces, making it comfortable to carry on your neck and easy to hold even for extended time periods without significant fatigue.

The polycarbonate body is coated with the rubber-like material, and the overall design is very sleek in order to provide for a binocular that is non-slip, easy to grip. Its compact dimensions of 5.7 x 5.1 inches make it easy to carry with you on all your outside adventures.

The Nikon Monarch 5 binocular is waterproof and the O-ring water seals can even withstand total submersion in up to 3 feet of water. This feature is especially handy to have if your outdoor explorations take place in rainy weather, near water bodies or in marshlands. This also means that you can clean the binocular by rinsing it in the sink. The internal atmosphere is filled with nitrogen gas to prevent internal fogging of the glass surfaces and it also prevents fungal growth, which may damage the glass coatings rendering your binocular useless.

Optics and magnification

The Nikon Monarch 5 10×42 binocular has a magnification power of 10x, and an objective lens diameter of 42 mm. This gives it an exit pupil size of 4.2 mm, which is a good size to use in almost all light conditions.

The prisms have a roof design that allows for narrow binocular. The prisms have a phase correction and dielectric high-reflective multilayer prism coating that provides almost the same brightness as seen with the naked eye, providing high-contrasting, clear images with accurate color reproduction.

The lenses are made from extra-low dispersion fully multicoated Eco-Glass. They enable high light transmittance across the entire visible spectrum, minimizing light scattering and reflection and providing clear, natural view. The ED glass reduces chromatic aberration, which in turn gives an image with higher resolution and contrast.

Focus and features

The body is designed with a central hinge on which a large, smooth central focus knob sits. The focus goes from close distance to infinity in 1.5 revolutions of the focus wheel. This is a relatively slow focus mechanism, and it allows for more precise focusing on the finer detail. This can be a bit tiring after a whole day of turning the focus wheel, but comes in handy when it is used from a standstill position and looking at fixed distance objects and need some finer detail.

The hinge allows for the binocular to be set at many interpupillary distances ranging from 57 to 72 mm.

The eyecups have a turn-and-slide motion that can be fixed in several positions, with rounded edges for a more comfortable fit. The eye relief is 18.4 mm, accommodating every user, even eyeglass wearers. There is a diopter adjustment ring that is located below the right eyecup, allowing the user to adjust to its own eyesight. This is not a lockable feature, but it has a stiff movement that keeps it safely in place.

Closest focus distance of the Nikon Monarch 5 10×42 binocular is noted at 7.8 feet, which is a good distance to observe close objects in high detail. The field of view is 288 feet at 1000 yards, having a more narrow apparent angular field of view compared to other binoculars of this size.

Additional gear

There are several things in the box beside the Nikon Monarch 5 10×42 binocular as well as carrying case that is made from nylon with light, soft padding to protect the binocular. The case has vinyl trim that is sewn to the back to form a loop that can be threaded through a belt or a backpack strap, allowing for easy carrying of the case.

Also included is a nice, wide nylon neck lanyard with the Nikon logo on it. The binocular comes with a rainguard and objective lens covers, instruction booklet, and the warranty card. The objective lens covers are made from a rubberized plastic material that stays on the barrels by friction fit. The rainguard is also made from a rubberized plastic material and does not have attachment clips to hold it to the binocular or lanyard, and it can slip from the eyecups.
