This optical instrument is well in the game as it is both waterproof and fog proof. The body of the binoculars is even nitrogen purged during manufacture to guard against fog. You can use this kit in all weather conditions and even submerge it up to 1 meter and still be able to use it without any problems.

Users have no trouble highly recommending these binoculars. The majority bought them for general outdoor viewing activities. The 10x magnification is great for tasks like bird identification, tracking wildlife or even spotting whales and dolphins at sea. You will need a steady hand when viewing at 10x power. Try using a tripod or simply prop your elbows on something sturdy like a rock or car seat.

The images from the Nikon Monarch 5 10×42 are sharp, bright and true to life. This is because Nikon is rocking it with top-quality optics. If you want the best you would do well to consider Nikon’s multilayer, coated lenses.

Top quality lenses

The lenses are precision made from an eco glass that is free of both arsenic and lead. One of the reasons the images from these binoculars are so true to life is that Nikon is using a specially manufactured extra-low dispersion (ED) glass in the lenses. The ED glass is able to correct for any optical colour defects before the image reaches the eye of the user.

Care has been taken to ensure the Nikon monarch 5 10×42 binoculars are lightweight. Nikon is specially manufacturing the casing from fibreglass-reinforced polycarbonate resin. The housing’s interior is blasted with dry hydrogen gas to ensure it’s clean. The instrument is then sealed with O rings as part of the waterproofing process.

It’s useful to understand the power rating of binoculars which is a standardised feature.


This Nikon Monarch 5 is the 10×42 model. This means the binoculars have a magnification power of 10. Any selected subject appears ten times bigger through the lenses. This makes it easy for the user to quickly find startlingly clear, true to life images of any chosen subject.

This particular model makes it possible to obtain crystal clear images in low lighting conditions. The generous 42-millimetre diameter objective lens, located closest to the action, optimises the available light. The bigger the objective lens the brighter the image.

You will enjoy using the precision-engineered Nikon Monarch 5 10×42 in many different sorts of field conditions. This high quality optical instrument is suitable for birdwatching, whale watching and other nature observation, amateur astronomy, sports, boating, travel and sightseeing among a wide range of general activities.

Safe cleaning

If you walk in from a day out in the field and put your binoculars away dirty you will transfer any grit and grime to the case where you run the risk of damaging the lenses.

If you’re loosening obvious particles of grit and grime try using a manual camera air blower and camel hair camera lens brush. The main housing of the binoculars may be wiped over with a clean cloth that is only just damp.

Avoid using a cloth that is wringing wet. Use cotton tips to clean around the thumbwheel (the focus control) and any difficult to get at nooks and crannies on the binocular’s housing. Try cleaning the lenses with a microfibre lens cleaning cloth or disposable lens tissue. If you are going to use an optical lens cleaner, make sure you use a cleaner from a camera shop or an optometrist. Apply a small amount of the cleaner to the cloth or the lens tissue. Whatever you do, please do not spray the binocular lenses directly as this may affect the binocular’s housing. Safety first as always, please refer to the manufacturer’s cleaning instructions.

Safety and insurance
We believe there’s merit in treating these Nikon binoculars with all the care owing to such a fine piece of equipment. For instance, Nikon is saying this product is waterproof in 1 meter of water for up to 10 minutes. We don’t recommend putting such factory specifications to the test. We are, however, recommending that you consider your purchase when renewing your insurance coverage.

Prices and purchasing

You’ll find the price of these Nikon binoculars extremely reasonable. Considering the high-quality manufacturing and many desirable features they offer, it’s a superb bargain. It’s best to ensure you select the best binoculars for your needs. To do this, look at the optic quality, lens size, magnification and brightness offered in your respective price range. These are all aspects you may discuss with your friendly local retailer when you are considering your purchase at your local shop.

You’ll find the Nikon Monarch 5 10×42 binoculars are a very useful tool. When purchasing something as niche as binoculars, it’s important to be sure that you are getting the best equipment available.

The history of binoculars
It’s thought the concept of binoculars is from 5th century BC Greece.

1661: Englishman John Dollond is credited with introducing the first monocular. Dollond said to be one of the earliest developers and manufacturers of cameras, microscopes and binoculars.

The beginning of modern binoculars
1950s: Physicists were exploring how to build small and powerful optical systems that could be used for surveying at night or in remote locations. An American named John David Littrow took on the challenge of designing an eye-level small binocular for night vision.

Foldable binoculars

Around the same time as the invention and development of the first monocular, a UK company called Gossen & Company created an instrument that could fit inside a case for a pair of eyeglasses. The binoculars were lightweight and portable. Gossen and Co get kudos for creating Its first folding monocular – ‘The Optacon’.
1967 saw the launch of “Optica, Inc.” and sales flourished in Europe, Africa and Asia until it passed to Nikon Incorporated of Japan.

The introduction of binoculars as a consumer product
Nikon leader Kenji Nadai created the first binoculars for sale to the general public in 1955. The company produced high-quality lenses and produced a quality monocular as well. In 1959, he presented the Nikon-Konic 7×50 monocular at a meeting of the American Society of Photographers and became an instant hit among photographers worldwide. The American photographer Maynard Kleven created images on behalf of Nikon Inc. for over 25 years. The Nikon 7×50 monocular went on sale in Europe in 1956.
