It has become popular equipment which is carried to the woods, especially shooting ranges. It is said that the traditional binoculars might be replaced by rangefinder binoculars in the near future due to its growing popularity. So, in this article, we are on a quest to introduce you to rangefinder binoculars and the top four of those which are available to you. The article also includes a buying guide you can follow if you are planning on purchasing a rangefinder binocular.
A company better known for digital imaging has entered the sports optics business with this binocular. Some testers were put off by the “plastic-y” feel of the KF and the durability score—one of the lowest in the test—reflects that. The optics are disappointing for a company on the leading edge of lens technology; the Fujifilm trailed the field in resolution and low-light performance. On the other hand, we liked the price and the portability of the aluminum-alloy chassis. The clicking center-wheel diopter is a nice touch.
Eye relief on a set of binoculars is very important if you use glasses. Take a look at Eye Relief in my glossary for a detailed explanation, but basically it is the distance behind the ocular lenses where the image is in focus. So if you wear glasses, you can't get your eyes as close to the lenses, you need a longer eye relief that basically projects the image beyond the ocular lens on the binoculars. So if you wear glasses, you should be looking for an eye relief of around 15mm or more, to see the full image full image. The down side to long eye relief is that it usually reduces the field of view.
There are multiple advantages of binoculars for birders over the other optical options. Binoculars are much more portable and lighter than spotting scopes and large telephoto camera lenses. Also, binoculars afford you a more natural “3D view” of the bird, since you are looking through two optical tubes and, therefore, viewing the birds with both eyes. Human vision is stereoscopic and sighting through two optical devices gives a birder the most natural view. Last, many spotting scopes and telephoto lenses require the use of a tripod or alternative support to ensure a steady view. This requires the birder to carry more gear into the field on expeditions.
We review the best birding binoculars available on the market and offer you our selection below. Do you have questions on how to choose bird watching binoculars for your specific application? While the typical optics consumer often favors high powered binoculars (16x is quite popular these days!), the more discerning birdwatcher has traditionally preferred relatively low power binocular models (7x, 8x and some 10x). High power certainly has its place in Bird Watching Binoculars, if you need to view small details at a greater than average distance, but lower power optics in your birdwatching binoculars have many advantages. One of these is exit pupil, which translates to binocular brightness. For example, when comparing two similar birding binoculars with the same objective diameter, such as an 8x42 and a 10x42, the lower power unit will have a larger exit pupil (42/8=5.25 vs 42/10=4.2), and therefore deliver more light to your eye. This is an advantage when you are out at dawn or twilight, or looking through binoculars at markings on a bird that is in the shadows of a tree. Lower power birdwatching binoculars typically provide a wider field of view, handy for scanning a large area for subjects of interest or more easily following moving objects, such as a bird in flight. Finally, you may have noticed that an 8 power binocular seems easier to hold steady than a 12 power binocular (we do have spotting scopes and binocular tripods and binocular tripod adapters that will work great with these binoculars!). The higher power, along with the narrower field of vision, makes small movements of your hands and body more noticeable, but larger objective and top quality lens coatings help to keep the view bright enough to be quite usable. Take a look below at our nature/birdwatching binoculars on sale and see what better fits your birdwatching needs. We guarantee you will not be disappointed!

In contrast, both the Swarovski and Leica models require you to pull back on the focus knob until it actually moves and you hear a click. Then you can use the focus knob to adjust the diopter. Once you're done, you can push the focus knob back into its original position, and you're good to go. While this mechanism works great on both models, there is the slight chance that you could pull the focus knob back in a fit of excitement and completely miss that Swainson's hawk flying by. This is by no means a common occurrence, but it is possible.
Yet another reason binoculars are excellent for beginning astronomers is that using two eyes is quite simply better than using one. Not only does it help when finding objects, but using two eyes with Porro prism binoculars will provide a stunningly beautiful three-dimensional effect that is much more interesting and, yes, exciting than the flat, one-dimensional view typically seen through a telescope. Not only is the depth of the view noteworthy, but the width as well. You can find astronomy binoculars with 5-6° field of view while most telescopes are limited to a 1° view even at their lowest magnification.
dless of whether you’re an expert with an extensive collection of rangefinder binoculars, or someone who’s only getting their first pair, choosing the right ones can be tricky. Making the wrong choice can cost you $90-100, or it could easily go into the thousands if you buy a premium pair of binoculars. When you consider all of the variables, making a wrong choice isn’t that hard. Things such as zoom or fixed, or image stabilization, or even the numbers in the name can be confusing for someone who isn’t well versed in the topic. However, as you saw above, clearing them up isn’t that difficult, and if you do know what you need, getting the right pair isn’t all that difficult either.
Since you're not looking at really far distance, I don't think you need anything more than 6x or 7x...this lower power will bring the subject in close while maintaining a wide field of view. If you need more power, I wouldn't go any higher than 8x. Also, depending on the objective lens diameter you go with, keeping the power to the 6-7x range you'll also benefit from a wide exit pupil and (generally) longer eye relief.
For the ultimate in light-gathering ability and night sky viewing, these Orion Mini Giant Binoculars are hard to beat. That doesn’t mean they’re the most cost-effective solution however. Comparable in size to the 15×70 Celestron, these Orion’s are priced about $150 more. What do you get for the added price? Mostly higher-quality components and lenses.
Keep 'em dry! The most common binocular problem, aside from getting knocked out of alignment, is moisture-related stains (often fungus) forming on the internal prisms and lenses. So be sure to let yours dry thoroughly after stargazing on a dewy night, or after bringing them into a humid house from the outdoor cold. If you expect dew and humidity to be a problem, consider sealed, waterproof binoculars such as these.
Range finding binoculars have become all the rage in recent years, especially among hunters, hikers, and nature fans. Combining traditional binocular functions with a modern range finder that shows you the distance to a target, they are incredibly useful. We researched 30 models and selected the ten best range finding binoculars for you. Let’s take a closer look.
One of the greatest advantages of binoculars comes from their very design. Unlike with a telescope, with binoculars you get to view space with two eyes. This is very important to give your brain the full visual experience. Not only does single-eye viewing severely hamper your depth perception, it also decreases your signal-to-noise ratio, which is not a good thing. When you have a high signal-to-noise ratio, your brain filters out much of the unwanted random impulses from each eye, leaving you with a better view of whatever objects you are looking at. In fact, many astronomers claim that color perception and contrast is improved by as much as 40 percent when using binoculars over a telescope.
And of course, Swarovski Optik El live up to it’s name. In terms of optical performance, this product outperforms the other three in this review (it’s slightly better than Leica Geovid). However, if you ask me, I can’t really differentiate the quality of image seen through this and Leica Geovid. Perhaps you have to be really professional to notice a difference.
While the Geovid indeed uses a laser to calculate distance, it also factors in ballistic trajectory. For example, the actual distance to an object might differ with a bullet as opposed to a laser. If you were holding a gun instead of the Geovid, the binos will factor in a bullet’s drop to give you perhaps the most accurate information on our list up to 1200 yards.
We expected this boxy, two-tone binocular from Cabela’s to cost so much more than its asking price of $190. Mechanically and stylistically, it seems like an optic that might compete with $1,000 offerings from European brands. We liked the Intensity’s crisp two-position eyecups and oversize focus wheel, front-hinge tripod adapter, fine balance and hand-gripping texture, and high-quality nylon carry case. By delivering all those features for under $200, the Cabela’s bino wins our Great Buy award.

Built for power, performance, and versatility, the 10-30x50 Level Zoom Binocular from Barska (B&H # BA1030X50B) integrates a thumb lever that allows you to take in a large field of view at a low magnification, and with a quick slide of the lever, increase the magnification to make detailed observations at a distance. Utilizing large objectives, anti-reflection fully multi-coated optics, and a traditional Porro prism optical path, you are provided with a rich depth of field and high-contrast images that are bright and clear with color rendition. Its protective rubber armoring is textured to provide a slip-resistant grip, and if you're planning on glassing for extended periods the Level Zoom can be mounted on a tripod using an optional adapter.
A related consideration is the exit pupil, the size of the little round disk of light that you see floating in the air behind the eyepieces when you hold the binoculars out in front of you toward a bright sky or a bright indoor wall. The size of the exit pupil is an important factor that's often overlooked. To determine it, just divide the aperture by the magnification — and luckily these are inscribed right there on the back facing you. For example, 7x50 binoculars have about a 7-mm exit pupil, while 10x50s have a 5-mm exit pupil.
The difference here isn’t that much in quality, but rather in size and bulkiness. All binoculars need a prism, as without one, they’d produce a reversed, upside-down image, which isn’t very useful. With a roof prism, you get binoculars with a straight profile, and the eyepiece is right behind the front lens. This is a fairly compact design compared to a porro prism. A porro prism, on the other hand, you have an offset lens and eyepiece, and this is the more common, traditional model. Both are great in terms of functionality, and it’s pretty much a choice of do you need a compact pair, or not.
Pros: The Aculon T11 Zoom is considered both high and low powered as you can choose from 8x, 12x, 16x or 24x magnification, making them versatile and a great pair of entry-level binoculars, particularly with its lower price tag. They are also the very lightest pair of binoculars we reviewed at 10oz compared to most other pairs weighing more than twice that.
If you’ve been shopping for binoculars, you will have noticed that some look very streamlined while others look chunkier. This is because the physical appearance and size of a binocular is determined by the type of prism it uses. Prisms are used to correct the orientation of the view horizontally and vertically so the scene looks natural; without a prism, binoculars would make things look upside down and flopped. There are two principal types of prisms: roof and Porro. The glass elements in a roof prism are in line with one another, making roof-prism binoculars more streamlined and easier to hold. Porro prisms have the glass elements offset from one another, and can provide greater depth of field and a wider field of view compared to similar roof prism models. This is accomplished by folding the light path, which shortens the length, spreading the objectives farther apart.
The only pairs with a locking diopter are the Leica Ultravid BCR and the Vortex Viper. The top pairs in this group with the smoothest adjustments and easiest focus were the Vortex Viper HD 8x42 and the Nikon Monarch 7 ATB 10x42. With all of these models even novices were able to follow birds in flight and keep them in focus without much issue. This is attributable to their smooth focus knobs.
The Bushnell Legend 8×42 give you great color depth and clarity for the price, and is my choice as the best budget birding binoculars. If you are coming from cheaper pairs costing less than $150, you will be surprised at the upgrade you get for about 1.5x the price. At 8x, its magnification is smaller than other 10x budget pairs, but when you look through it, you won’t be disappointed by the view.
Another recent innovation is image-stabilized binoculars. These employ the same ingenious mechanisms found inside the best video cameras. Push a button and the shaky magnified view suddenly calms down, almost freezing in place. The result is that you can use higher magnifications, get away with slightly less aperture, and yet still see more than with conventional binoculars.
As for cleaning your binoculars’ lenses, what you don’t want to do is start cleaning by breathing on and then rubbing the lenses with something like a microfiber cloth, lens wipe or—heaven forbid—your shirtsleeve. That’s because doing so may lead to the dust that’s already on your lens leaving tiny scratches. Instead, start with a lens pen or bulb-type blower to remove that dust, then go ahead and use either lens wipes or fluid and a microfiber cloth. For more info, visit our guide to the best camera cleaning gear (the routine for cleaning binoculars is fundamentally the same).
Digiscoping The use of digiscoping adapters has seen an increase in recent years, since just about every phone in everyone’s pocket is equipped with a camera. These adapters, either binocular, phone-specific or (growing in popularity) universal fit, allow you to mount your phone on one of the eyepieces and take photos of the magnified view. Depending on the manufacturer, these adapters can be made of plastic or metal with varying degrees of usability options. The good news is that as the hobby grows, more and more options are made available so you can spend as much or as little you want.
Which are all crucial considerations, as binoculars tend to be highly subjective. It’s helpful to think of a pair as you might a new car: you want a rare symbiotic union of stylistic penchants, pragmatic details and clarity of vision that all mesh with whatever price point you’re willing to live with. Because the moment you drive it off the lot, the resale value craps out. There’s no monolithic pair that everyone should own, no starter set that’s worth the $200 you could just apply towards pricier lifetime binoculars. While cost is often a barometer of quality, it’s not always. Instead, a thornier set of metrics obtains: are you after high magnification for long-range birding — owls and shorebirds and the like — or will 7x or 8x suffice? Do you want a lightweight pair to stow in your glove compartment, carry-on or briefcase? How important is balance, overall feel, focus, and what birders call “eye relief” (basically visual ergonomics) to you? Because they’re different for everyone. In short, will you be driving an Audi 6 or a Ford Fusion?
One aspect of binoculars often overlooked by birders is minimum focusing distance (or close focus). The binocular brings the distant bird visually closer to the birder for observation and analysis, but the Audubon Society’s Eric Lind is quick to point out that birding can easily involve looking closely at birds and insects that are relatively close to the observer. Having a close minimum focusing distance might give you an amazing close-up view of that feeding hummingbird or majestic butterfly. Binoculars with higher magnification will, in general, have longer minimum focus distances.
Looking at the basics, you’ll find that all binoculars come with a set of two numbers. They can be 7×42, 7×50, 8×42, 10×52 etc. This is a pretty important number with rangefinder binoculars, and any binoculars in general. The first number will tell you the magnification. For example, a 7×42 will show you objects 7 times closer than the naked eye. The second number tells you how big the objective lens is in mm. A larger objective lens lets in more light, and you’ll be able to see a brighter image. This could be especially beneficial in darker conditions. What you should know is that higher magnification will reduce the amount of light that’s available, and a large objective lens will make the binoculars large and heavy.
The exit pupil is the size of the focused light that hits the eye. To see the exit pupil, hold the binocular eight to ten inches away from your face and notice the small dots of light in the center of the eyepieces. Exit pupil diameter, which should always be larger than the pupil of your eye, is directly affected by the objective diameter and the magnification. The pupil of a human eye ranges from about 1.5mm in bright conditions to about 8mm in the dark. If your binoculars’ exit pupil diameter is smaller than the pupil of your eye, it’s going to seem like you’re looking through a peep hole. Bear in mind that as eyes age, they tend to dilate less, so exit pupil becomes more important as the user ages.
If you want to explore the great outdoors with your kids, then the Educational Insights GeoSafari binoculars are the best pair to get them started. The pair of kid-friendly binoculars feature soft-grip handles for smaller hands, while kids can explore nature in-depth with their 30mm glass lenses and 4x magnification. There's also a trusty compass attached for some light orienteering. Moms and dads will love that these binoculars can help their kiddos get into STEM (Science, Technology, Engineering and Math) learning.
There are two separate categories that your binocular use can fall into. The first is bird watching and hunting. These activities generally require higher quality binoculars. Recommendations from the Audobon Birding Society call for binoculars that have a magnification of around 6 to 8 times for optimal bird viewing. Any higher, and you will likely have trouble locating animals in the scope, as you’ll lose points of reference when putting the binoculars up to your eyes. The same should be taken into account for hunting – where getting an animal in your binoculars’ viewing range quickly is paramount.
Optically, the TrailSeeker offered exceptional light-gathering abilities. I remember watching a northern harrier soaring against the sky and the colors of the streaks below were as sharp as can be. Another bonus is this pair’s ability to focus close—as near as 6.5 feet, with a field of view of 426 feet at 1,000 yards. However, the outer edges of that expansive field of view had some mild distortion. The streaks on a Lincoln’s sparrow got a little mushy through the edges of the Celestron lenses, yet remained razor-sharp through the lenses of the Athlon Optics Midas ED. Most users probably won’t notice this, but the Athlons were clearly superior, to my trained eye.
Younger and smaller skywatchers need smaller binoculars to fit their hands and faces. These Big View binoculars by Learning Resources are perfect for the youngest stargazers and bird-watchers. Designed for kids age 3 to 12, these binoculars are safe and easy to use. The binoculars come in a durable, plastic frame with plastic lenses, so parents don't need to worry about the hazards of broken glass or other broken parts. Rubber eyepieces make these comfortable to use, and a breakaway lanyard ensures that kids won't get tangled or hurt. A plastic focus knob allows the user to manually focus the view. Compared to more-expensive binoculars for adults, these have a relatively low power of magnification (6x). However, for the price, these binoculars are an excellent choice for kids.
