Main Use For The Nikon Monarch 3 Binoculars

With the ideal magnification and unbelievable image quality, the 7451s are the perfect choice for the shopper on a budget, who wants a pair of binoculars for general all round use.Nikon-7451-Monarch-3-10X42mm-Binoculars02

Where perhaps the magnification is not enough for precision bird watching or marine mammal observation, it’s more than adequate for getting closer to the great outdoors, hunting, view sports games and bringing that distant hill into view.

With a rugged and durable polycarbonate body, these binoculars can withstand a certain degree of rough and tumble, meaning they are the choice for the slightly messier hikes that could involve a couple of scrambles up the hillside.

The image quality of these binocular is highly regarded among users, and rightly so.

As a result of this you can rest assured that for whatever purpose you have in mind for these wonderful binoculars, you’re going to be getting the very best view of it.

Nikon 7451 Monarch 3 10X42mm Binoculars

From reading various articles, and writing various reviews, it’s become apparent to me that Nikon are establishing themselves as the kings of glass, lenses and enhanced optics.

The ever successful silver alloy phase correcting prisms make an appearance again here, with their inseparable counterpart extra low dispersion glass lenses.

These two combine to give an unrivalled degree of quality that once again smashes previous benchmarks and leads you to expect a whole new level of quality.



Offering an impressive 10x magnification over a 42mm objective lens, the 7451 is real for both landscape viewing and honing in on a point of interest.

The field of view is impressively wide, with an easy to access central focus knob to bring aspects of the image into clarity. 10x magnification is almost the perfect balance, with the scope of vision of an 8x model, with enough detail that usually is provided at 12x magnification.


Image Quality

Image quality is where these Monarch 3s really stand out from the ever growing binocular crowd.

To sum it up in one word, the word would have to be phenomenal.

The quality is so highly regarded among binocular users that it’s hard to find something better without going into a four figure price tag.

The enhanced optic system, featuring highly reflective silver alloy phase correcting prisms, prevent degradation of image quality over different light phases, meaning you only see the best quality image, at the a well lit stage, with the highest of resolutions.


Eye Relief

As we have come to expect from Nikon binoculars, there are no qualms when it comes to the degree of eye relief present.

With a giant 17.4mm from cup to lens, there is more than enough space for you and your glasses.

The successful multi click turn and slide eyecups make a reappearance here, meaning that comfort is once again a guarantee.



The real stand out benefit of the 7451s is the image quality.

From the precision engineered glass lenses, to the prisms, to the magnification, these binoculars well and truly deliver.

The image is crisp and clear, at an unbelievable resolution. The image quality is so good, that users are toting it as ‘the best image quality under $1000’, which is some feet for a $200 pair of binocs.



It baffles me why manufacturers have not taken steps to improve on the one drawback of the previous Monarch 3 model.

Unfortunately, even though this pair is a massive step in the right direction in terms of image quality, the same cheap, easily broken lens covers are present, meaning that when they inevitably break off, your precious binoculars are open to the elements, and will receive some degree of damage eventually.



Nikon 7451 Monarch 3 10X42mm BinocularsIn conclusion, if you’re looking to buy a pair of binoculars on a budget, or even if you don’t have $1000 to splurge on a pair, look no further than this pair from Nikon.

It’s difficult to get on the page just how good the image quality of this binoculars are, all I can say is that all the hype and praise given to the quality is more than deserved.

For all round use, price, quality of image and quality of build, I personally challenge you to find a better pair in a similar price range.
