Keep in Mind Prior Purchasing:
The first pre-purchase factor to take into account is the magnification capability of the given monocular. A good monocular will often provide enhanced magnification levels that average at 6x to 10x, which is perfect for most use cases.
Lens Size: If you evaluate the particular specs of the lens, you will often come across numbers such as ‘8×25, which indicates the size of the lens. It is important to note that the 8x stands for the power while the 25 stands for lens size. In most cases, most monocular come with a lens that averages in between 20mm and 42mm. The field of view of the lens is directly dependent on the size of the lens, which means you should consider the larger lens sizes. However, the notable drawback might be that it might have an increased weight as when compared to its smaller counterparts.
Eye Relied: Another important factor to take into account is known as eye relief. This is especially perfect for users who have poor vision or perhaps when you are using the lens in poor lighting conditions. In most cases, the eye relief is measured in millimeters, and it refers to the furthest distance that the user can use the piece while maintaining the best field of view. If the user’s eye if far away from the recommended eye relief distance, this may compromise the visibility levels. For this reason, you the best suggestion would be you to choose a monocular with an average eye relief distance of 14mm to 16mm.
Lens Coating: The monocular coatings are available in various types of finishes including multi-coated and fully multi-coated among various others. Each coating is associated with enhanced brightness levels, image clarity and it works to mitigate the effects of any glare that may arise from secondary light sources. However, the lens coating feature means that you may have to pay more for the monocular that the conventionally coated lenses.

Monoculars offer an alternative way to have clear and crisp images without the heavy, bulky binoculars. They are generally the best for beginners since they have low magnification. Low magnification means that you get the images with less shaking and blurs.
Owning a monocular is a great alternative to carrying a pair of binoculars. Being only half the size of binoculars it is significantly more compact, light and portable. The following guide talks about how to choose the best monocular for your budget and needs.
What is a Good Monocular Power?
The first thing to look at when choosing a monocular is its power or magnification. A monocular will typically have a magnification of 6x to 10x – higher magnification will allow you to see further and in more detail. 9x or 10x monoculars will usually cost a bit more than 6x or 8x ones. The good thing about a monocular is that you get the same power of binoculars with only half of their size.
What is the Right Lens Size?
If you look at a monocular’s specs, you will always see two numbers. For example, 8×25. The first number represents its power (8x) and the second number its lens size (25mm).
A monocular will normally have a lens of 20mm to 42mm. A bigger lens will allow you to see a wider view. A bigger lens will also result in a better, brighter image when looking through your monocular. The downside is that the bigger the lens is, the heavier and bulkier your monocular will be.
Monocular Size and Weight
In general, an 8×25 or 10×25 monocular is considered to be a compact/pocket monocular. It will easily fit in your pocket and be very portable. This type of monocular will usually come with a small carrying bag. The pocket monocular works as a cool gadget as it’s easy to carry around everywhere, keep in your car or in your pocket when hiking. Pocket monoculars are cheaper and can also serve as a nice gift to someone.
Remember not to expect too much performance from an 8×25 or 10×25 pocket monocular though! These little monoculars have good power but a very limited view because of their small lens. You will need to first identify your subject and then use the monocular in a “point and shoot” manner. They can also be difficult to use due to their very small eyecup. If you want to enjoy a wider, sharper and brighter image, then you should always opt for a 30mm to 42mm monocular.
Monocular vs. Spotting Scope
A monocular is designed to be very compact and portable. Larger monoculars with more power, bigger lenses and wider views are called spotting scopes. A spotting scope will be significantly bigger and heavier than a monocular. These are often used for hunting, bird watching or spotting subjects from a fixed location. So if you need better performance and don’t mind the size or weight, then you should consider getting a spotting scope.
Night Vision Monoculars
If you are looking for a monocular to use at night or complete darkness then you should consider a night vision monocular. These monoculars use a built-in IR illuminator to allow night vision capability. They normally have less magnification in order to provide a better image (less fuzzy). Night vision monoculars range in sizes, magnification and price.
Taking The Long View: Distance Optics
The earliest functional telescopes were designed by Dutch spectacle makers in the first years of the 17th Century. In the year 1609, Italian astronomer (and mathematician and philosopher and scientist writ large), Galileo Galilei designed an improved version of those first refracting telescopes. He pointed it skyward, becoming the first person known to have beheld a celestial object in a manner refined beyond the vision of the naked eye.
From those rudimentary optical devices have descended everything from the observatory to the Hubble Space Telescope, to the pair of binoculars tucked into the backpack of the hiker. And of course something else was born, too: the field of modern astronomy and a better understanding of the entire universe.
Today, there are many reasons for why a person might want to extend his or her vision out across a great distance. With the right optical hardware, one can enjoy a better view of a sporting event, concert, or a parade. Enhanced long distance vision is important for bird watching and other nature activities, or for hunting, too. In a tactical situation, such as a police stakeout or combat scenario, the better one can see from farther away, the safer they and the team remain and the better they can control the unfolding events.
Long distance viewing can also be important for various professional applications, such as surveying land prior to development, or in studying city streets or highways before an improvement or repair project. And of course the stargazer needs good optics to best enjoy the celestial bodies above.
Choosing the right device for your long distance viewing needs might not involve considering a massive astrographic telescope, but there are still a few considerations to keep in mind.
Why Monoculars Are Often Better Than Binoculars
If there is one primary reason why a monocular is often a better choice than a pair of binoculars, it is weight. By the very nature of their design, a pair of binoculars will usually weigh twice as much as a monocular with equivalent magnification power. If you’re assembling a kit for use in a tactical situation or you are a trekker or climber carrying your gear over long distances, weight matters.
While many people prefer the stereo vision afforded by binoculars, which recreates the way the human eyes see together, when you are trying to view a distinct object or a limited area without much depth, the monocular’s flatter view can help you isolate the image more easily.
Because binoculars usually allow focusing adjustments for both eyes, with a center knob controlling both sets of optics and one side of the unit featuring another ring for fine tuning (most people have slightly different vision quality in each eye), they can provide a sharp view indeed. But that also means more effort required to achieve this sharp view, and it means more potential for improperly focused optics that can cause frustration, eye strain, and that can hamper your distance vision instead of helping it.
Monoculars also offer enhanced potential for situational awareness, as you can maintain your view of the long range object or area in question yet open the other eye for a quick review of the space closer to your person. This can be of critical importance in combat or emergency situations.
Choosing The Right Monocular For You
The first thing to note when considering which monocular you will buy is magnification power. But consider the fact that stronger is not always better. The more powerful a monocular’s magnification power, the harder it will be to keep it steady and in focus. If you are hoping to get a better view of objects that aren’t that far away, or if you value a wider field of vision over greater range of vision, than look for a monocular with midrange magnification over one with extreme power.
Choosing a monocular that has a zoom feature can mitigate the issue of too much power, but with zooming in and out comes even more difficulty in achieving perfect focus, so know the give and take a zoom option offers you.
Next consider the time of day during which you will use your monocular. Many monoculars have amazing light gathering capabilities and work well even in darkness. Still others have actual night vision capabilities, sending out their own infrared light that can you can detect thanks to their specialized lenses. A night vision monocular is a great idea for many nature scientists or for use in tactical situations. However, most monocular that work well at night have optics that are objectively inferior in daylight. If you are primarily going to use your optical gear during the day, then you have many more options for a good monocular.
Ultimately, choosing the right monocular may well come down to its physical size and weight. If you are a hiker who regularly carries large loads of gear on your back, then every ounce matters. Opt for a smaller monocular and enjoy the view it affords you, even if other larger models have better magnification. If you are unconcerned with gear weight, then by all means choose an option large enough to be used as a spotting scope while hunting or as a compact telescope for viewing the firmament.
