Expensive. In this case, rangefinder binoculars are pretty expensive, irrespective of the models. Even if you are searching for the cheapest rangefinder binoculars in the market, it’s going to be at least a few hundred dollars (which is pretty rare). The average price for something decent is going to cross the $1000 benchmark. Of course, if you do plan to get a rangefinder and a binocular separately, then perhaps a rangefinder binocular will be cheaper than the price of both the devices combined.
Some binoculars can have integrated digital and analog compasses. They will often have the direction displayed in the field of view for easier use and bearing reading. Digital compasses are battery powered and illuminated for use in most light conditions. Analog models can use batteries or might have an opaque window on the top of the housing to channel and focus ambient light to illuminate the compass. Many marine, image-stabilized, and rangefinder models offer versions with or without compasses.
When looking at spec sheets on binoculars, birders may notice that they have two standard types of prisms. Chris’s article gets deeper into this, but we will discuss it briefly here. The BAK4 prism provides a more circular field of view and is considered superior to the BK7 prism’s rectangular field of view, as the BK7 may cause vignetting of the image. There are wonderful binoculars with the BK7 prisms, so do not discount the variation; it is just something to be conscious of when comparing binoculars.
I'd like to get a binocular for my wife who is legally blind and has also some degree of night blindness. We travel extensively and she loves watching nature (animals on safaris; mountains; etc.). I was thinking that a binocular with a large aperture and wide field might be a good choice, such as the Steiner 8x56 ShadowQuest Binocular. I like the good performance during dawn, becasue of my wife's impaired ability to see in low-light environments. What do you think? Any other types I should consider?
AWESOME! These Binoculars are really great especially for a beginner night sky watcher like myself. They were easy to start using and I am really enjoying them. While I hope to eventually graduate to a telescope, for someone who is just starting out, these are fantastic and are a great bang for the buck as well. I would definately recommend these to any amateur sky gazer.

Objective lens size: This refers to the size of the front lens, which determines how much light gets in. A larger objective lens will make it easier to see greater distances, as well as improve visibility at dawn or dusk. They cost more, but most birders agree that larger objective lenses are a must. (Note: Most binoculars are identified using magnification and objective lens size paired together, like 8x32 or 7x42. As a general rule, the wider the ratio, the larger the image. For instance, an 8x42 pair of binoculars produces a larger image than a 8x32 combination.)


As we touched on in the previous section, the greater the magnification capabilities, the lesser the field of view. Since telescopes are generally more high-powered than binoculars, they are notorious for having a very limited field of view. If you know exactly where the celestial objects you plan on viewing will be, this may be less of an issue, but if you need to scan the sky to find planets and stars, this can be very problematic. Seeing more of the night sky at once also gives you a better appreciation of how objects relate to one another in size and distance.
When my wife came along, we upgraded to a pair of Steiner binoculars (now lost) and lived briefly in a new visual milieu, utterly fresh and imposing. Things appeared as they never had before. Being owl people, our birding gestalt began to follow an inexorable course toward higher magnification, all the way up to 10x. We’re also urbanites with a young child and do 90 percent of our birding from our porch at sunup, with nuthatches and chickadees flitting about in a hazed cityscape, so we also like a wider 8x field of view. Though slightly less broke, we drool over the sale bins at Target. We’re also fairly lazy, it must be admitted, and would prefer our binoculars to be as light as cotton, and for someone else to do the lifting.

Birders demand a lot from their binoculars. Birding binoculars must be light enough to carry all day long and sturdy enough to survive years of heavy use. They must be easy to hold steady. They must resolve delicate details and reveal subtle colors with accuracy. They must focus quickly and up close and work well in dim light. They must be sealed from dust and moisture. And they must show the whole picture even for birders wearing eyeglasses.
You may also find more numbers below the magnification-x-aperture rating. These give the field of view, which is how wide a scene you'll see. It's expressed in feet at a distance of 1,000 yards, or, more commonly these days, in degrees. (The conversion is simple: 1° is 52 feet at 1,000 yards.) Binoculars' fields of view vary from about 10° (the size of the Big Dipper's bowl, or the size of your fist held at arm's length) for wide-angle models, to a mere 2° (the width of your thumb at arm's length) for high-power models. Most of the time, though, the field of view is about 5° to 8° wide: about as much sky as is covered by a golf ball or squash ball held at arm's length.
Modern binoculars all come with an adjustable eyecups around both eyepieces. This is either a foldable rubber cup or one that adjusts in and out using screwing motion. The simple rule of thumb is that if you wear glasses make the eyecup as small as possible, i.e. you need to get your glasses as close to the glass eyepiece in your binocular as you can.
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.
Whilst it is true that these may not match the very high end "alpha" type instruments on this page, features like fully multi-coated optics, BaK-4 roof prisms with phase corrective coatings and water repellent lens coating on the exterior demonstrate that this is still a high quality optical instrument and will deliver a more than satisfactory image even in low light.
Build quality is another one of those crucial areas when it comes to a precision optical system. High performance optics require painstaking manufacture within extremely tight tolerance limits to deliver consistent levels of quality in the finished product. The slightest misalignment of any component in the construction can seriously affect the performance of the binocular.

In light of the foregoing, is it any wonder that binoculars are well recommended for astronomy beginners?!? In typical conversation with astronomers, the term "astronomy binoculars" is applied to those binoculars with 60mm diameter or larger objective lenses. For convenience, however, we're going to use that term for any binoculars used for astronomy.


Wider field of view. You spot a bird high up in a tree and quickly raise your binoculars to your eyes. The wider the field of view, the more likely that your aim will be correct and that the bird will instantly be in the field of view, without having to search about for it. This is especially true for smaller, fast moving birds that don't stay put. Lower magnification in binoculars means a wider field of view, so many birders prefer 8x to 10x.

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.
That’s not much to go on, and a lousy assessment of an optic’s best asset: the glass inside its tubes. That’s where Out- door Life’s annual Optics Test can help. We rst measure the optical clarity of a bin- ocular or riflescope on a resolution range. Then our test team (for personnel, see p. 54) measures how late into the darkness the submissions can see a black-and-white target (we do this on three separate eve- nings and average the results). We then peer into the guts of the optic with ash- lights, assessing internal lens coatings and quality of construction. We shoot with the riflescopes to assess their reticles and turrets. We glass with binoculars. We rate products on repeatable measurements of optical and mechanical capability and on subjective assessments of performance. We also assign a value score to each optic; the product with the best value score wins our Great Buy award. The top overall score in each category gets our Editor’s Choice award.
Binoculars come in two basic configurations: Porro prism or roof prism. The Porro prism gives that type of binoculars the traditional binocular shape. The roof prism binocular features a narrower and compact, straight design. There are advantages and disadvantages to each, but, in general, the Porro prism design is less expensive to manufacture and, therefore, gives you more bang for your buck as far as optical quality and features. The relative compact size of roof prism binoculars makes them generally more popular for birders, as optically similar Porros will be larger.
After saving for two years for an optics purchase, I am very happy with this product! Originally I had intended to buy a high end rifle scope, but why have a bunch of expensive rifle scopes sitting in the safe? Instead, I decided to streamline my archery hunting setup by going with rangefinding binos that I would get more use out of. Let's be honest, these Nikons are no Swarovskis, but they come pretty darn close to my Swaro EL 10x42. For long range rifle hunting here in the West, nothing beats my Swaro 10s and 15s along with my Gunwerks BR-2 rangefinder. Even though the Nikons boast 1900 yard ranging, for me it will be for archery only. It has been amazing white shooting 3D! Now for the hack mentioned above. I made a "silicon dimple" on the range button by masking off a little square with blue masking tape. Then I put a dollop of Mcnett's Seam Sealer on the button. When it cured (24 hours), I had a nice custom tactile range button I can locate with out looking. If you are picky about optics and know the value of a dollar...you won't be disappointed.
Very bright, clear display with 4-step intensity adjustment; easily readable under any lighting conditions and against various subjects, with single or continuous measurement up to 8 seconds. Displays in increments of 0.1m/yd, when shorter than 100m/yds and in 1m/yd at 100m/yds and over. Auto power shut-off function saves battery life by shutting down after 8 seconds of non-use.

To get the price down, the Monarch 7 does have to sacrifice in a few areas compared to the higher end and more expensive optics. The most significant difference you would notice is the quality of the image, especially in low light situations such as a darker forest canopy, sunrise or sunset. The Monarch 7 does reasonably well, but it doesn’t come close to the overall image quality of a Zeiss Victory SF or Leica Noctivid.
Pick the units with round exit pupils; this tells you that quality prisms were used and that you're getting all the light you should. (You can also check the specification sheet: the best prisms are made from BAK-4 glass, while others use BK-7 glass.) Since they're hidden inside, the prisms are one of the first things manufacturers skimp on when trying to lower the price. Seeing "shaded" or "squared off" exit pupils is a sign of lesser-quality or undersized prisms.

High-performance features include: fully multi-coated optics and BAK-4 prisms, and custom adjustment with center and right diopter focus knobs. They have an extra-large field of view with crystal clarity from edge to edge; Ultra-smooth center focus that's easy to operate, allowing you to pinpoint your subject, Right diopter adjustment so you can fine-tune your viewing.
Birders demand a lot from their binoculars. Birding binoculars must be light enough to carry all day long and sturdy enough to survive years of heavy use. They must be easy to hold steady.

And they must show the whole picture even for birders wearing eyeglasses.

Decide on your price range. Top-of-the-line binoculars give you a pristine image in a comfortable, durable package. Lower price ranges also offer some great options, thanks to technological advances in the last decade. See our chart of Performance vs. Quality Index to look for your best value. Note that we provide MSRP (from October 2013), but many retailers sell binoculars at below this price.
The EL only has one downside, and it's a big one: price. Listing for $2,888 these bins cost as much as a used car and are more of an investment than a purchase. However, if you're a serious birder or wildlife watcher that wants the absolute best, or you're embarking on a once in a lifetime safari, these bins will undoubtedly elevate your experience.

This is a supersized binocular suited to glassing distant targets for long periods of time. The double-hinge design creates a nice space for hands to hold it, but you will probably want to mount this 3-pound Leupold on a tripod. The mounting bracket is smartly located on the inside hinge of the Leupold (see Innovations, right). Hits: tight controls, the battleship-gray armor, the webby texture that wraps the aluminum-alloy chassis, and the first-rate carry case and neck strap. Misses: disappointing resolution and image quality.
Oculus packs a number of premium features in this compact, hand-filling 42mm binocular, including a tripod adapter, thumb detents on the underside of the barrels, a very precise clicking diopter control, and a cushioned nylon case. The optics, delivered through “ultra high-definition” glass inside the magnesium-alloy chassis, are solid, finishing in the middle of our full-size field. Our quibble is with the controls. The closed center hinge is so stiff it takes some serious work to spread the barrels, and the focus wheel is spongy.
Measuring only 5 ½ inches long, this new Nikon delivers a lot of optical horsepower in a compact and lightweight package. And what an elegant package it is. The Monarch HG has a number of stylistic features that reminded us of the last premium Nikon binocular: the EDG. There’s the pebbled-­rubber armor, the finely turned eyecups, and the Euro-style metal objective lens rings. The Monarch delivers an image on par with the premium furnishings. The “field-­flattener” lenses widen the field of view and reduce peripheral distortion.
Now, as far as rangefinders are concerned, the most popular size is 7×50. There are sometimes 10×42, or in Zeiss’ Victory, 10×56. These are all numbers that you could go for. However, less than 7 times magnification won’t do the job. On the other hand, more than 10x, and you won’t be able to get as much light to your eyes, and the image will be darker. As far as the objective lens size goes, if you can’t mount the binoculars on a tripod, you will need something with an objective lens not larger than Zeiss’ 56mm, as it will be heavy and difficult to handle.
Edge Sharpness: All binoculars have a “sweet spot” in the centre of the field of view where the image is in sharpest focus before some loss of sharpness as you move out towards the image edge (a phenomenon known as field curvature). The wider this central sweet spot, the more enjoyable the binoculars will be to use. The better the binoculars, the larger the sweet spot, and the less softening you get as you approach the image periphery. Some premium binoculars (like Swarovski’s flagship EL Swarovision range), incorporate special “field flattener” lenses in the eyepieces to deliver a clear view right to the edge of the field.
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.
Most roof prism binoculars are made in Germany. Porro prism binoculars are made in Japan. Whatever design you choose make sure the binocular has Bak-4 prisms and the lens is fully multi-coated. Also because it is a well known European brand does not mean it is safe to buy that binocular. Some binoculars are shipped to Germany from Korea with no country of origin marked on the binoculars. When said binoculars left Germany they were then stamped as being made in Germany. On a similar note, if buying binoculars made in either the former Soviet Union or China you might be getting a good deal, but buyer beware. If you can, try them out first and make sure the dealer has a liberal return policy.
The area of space that you can see through binoculars is smaller than expected when compared with what can be seen with the naked eye. For this reason, it is better to find the stars (or constellations) that you want to view with your naked eye first. Keeping your gaze fixed on the same spot, swiftly bring the binoculars up to the level of your eyes and peer through them. Another way is to find a bright star and, using that star as a reference point, gradually move your binoculars’ field of vision in the direction of the galaxy or star cluster that you wish to view.
"These binoculars provide a clear view of wildlife in my backyard or while on a nature walk. I agree they are built like a tank, but not the weight. I was looking at other brands and decided on the Carson's VP series. I made my decision from reading the reviews and watching the Carson provided product videos. I can't wait to view more wildlife with them."
For wildlife watching and birding you really want a binocular that is completely waterproof to give you piece of mind when using your optics across a wide range of conditions. Most roof prism binoculars on the market today that are suitable for birding and wildlife are  waterproof, and are purged with an inert gas (either nitrogen, or less often argon) to drive out water vapour and eliminate the potential for internal fogging when moving between extreme temperature gradients (from a warm car onto a wintery moorland, for example).
ED or HD lenses: Extra-low Dispersion (ED) or High Density (HD) lenses are used in the objective lens elements of premium binoculars and spotting scopes. Their principal purpose  is to correct for a phenomenon called “chromatic aberration”… or colour fringing. Colour fringing can be an issue with standard binoculars, particularly when viewing high contrast subjects (light subjects against a dark background and vice versa). ED or HD glass reduces or eliminates colour fringing, improving the perceived sharpness, contrast and colour fidelity of the resulting image.
AWESOME! These Binoculars are really great especially for a beginner night sky watcher like myself. They were easy to start using and I am really enjoying them. While I hope to eventually graduate to a telescope, for someone who is just starting out, these are fantastic and are a great bang for the buck as well. I would definately recommend these to any amateur sky gazer.
A simple trick for spotting stuff faster with binoculars: Don’t hold your binoculars up to your eyes and then pan and scan for what you’re trying to spot. You’ll never get there. Instead, with the naked eye, stare up at what you want to see, then raise the binoculars to your gaze. That’ll allow whatever you’re looking at to instantly pop into your magnified view.
As one of the safest, easiest, and most environmentally friendly hobbies in existence, birdwatching brings together people of all age groups through a common love of wildlife. Birdwatching can be done practically anywhere, though avid hobbyists won’t hesitate to travel the world in search of the rarest species of birds. A good set of binoculars is the most important piece of equipment involved in birding, and buying the perfect pair is worth an investment in time.

It has a magnification of 10×42. When combined with the lens quality, it lets you the ability to observe far and give crystal clear images of your target. It has an 18 mm eye relief. It is considered to be one of the highest which it comes to rangefinder binoculars. It results in your eye being comfortable the whole time you are staring through it. This is the rangefinder binocular you should buy if you are looking for something which is a symbol of perfection. Click here to see the best price. Click here to see the best price.
On the other hand, if you are happy to keep your binoculars fixed in one location and used mainly for astronomy and long distance viewing then go with a larger and more powerful model. Remember that the larger the lenses are, the better your binoculars will be for astronomy – as simple as that! It is no surprise that most astronomy binoculars are also referred to as “Giant Binoculars.” Big lenses mean brighter images.
And while a touch big for my pack, the Monarch 5’s were a perfect match for the Badlands, where long, grassy ranges and distant, rolling hills demanded extra magnification and then some. Golden eagles, western meadowlarks, bobolinks, curlews, a ferruginous hawk, spotted towees, northern harriers, western kingbirds, and black-rosy finches — I crossed them all off my list. No matter how you slice it — optical quality, resolution and brightness, eye relief, body mechanics — the Monarch 5’s match up against binoculars that cost two or three times as much.
With an eye relief of 20 mm and 8.5×42 magnification, this rangefinder binocular is the perfect fit for those wearing glasses. This is because it offers a lot of places for you to adjust behind the lens while wearing glasses. The focus wheel is placed perfectly where your hands can comfortably handle it. The dioptre adjustment is incorporated with the focusing wheel. This lets you to simply pull back the wheel and turn it to change the dioptre scale.

***Important Note: Most companies don’t reveal much detail when it comes to the below information. These are kept a secret so as not to lose a competitive advantage. For example, Zeiss has been in business a LONG time. They have perfected their engineering and coatings over many years and are not very willing to share their best practices with other companies!***

The focusing action on the binoculars is very smooth, and stunningly precise. The lock-to-lock is around two turns , you might think this is slow, but going from a few meters to infinity only takes one turn. Why, then does it take two full turns for the full travel? Because their focus distance is very close, at 1.5 meters. Optics are what you’d expect from Swarovski. The prisms are conventional roof prisms with mirrors. Again comparing them to the Zeiss Victory, they transmit around 3 to 5% less light than those models, due to the mirrors’ scattering. As far as the objectives go, you will find a pretty complex design with around 12 optical elements on each side. Among the most important parts that Swarovski included in its battle with Zeiss and Leica are the HD lenses. These lenses have high-fluoride glasses which, in a way similar to apochromatic telescopes, reduce chromatic aberration. With a fairly large air gap, you will find at least four elements in the Swarovski EL.

Combining excellent optical performance with ruggedness, portability, and comfort, the 10x50 Diamondback Binocular from Vortex Optics (B&H # VODB10X50) is ideal to take along on your hiking trips, camping, traveling, or just in case. The specially designed optics feature improved transmission, contrast, and true color using fully multi-coated lenses and phase-corrected roof prisms. With the improved close focus of 7' you will get plenty of focusing range and a sharp focus on faraway scenery as well as close-ups of nearby street signs, monuments' details, or wildlife. The combination of 10x magnification and the 50mm objectives, which are ideal for low-light conditions and even star-gazing, offers you a generous 6° angle of view that gives you complete images of targets.
Let’s take a look at what’s important. First of all, the USCAMEL feels very solid. Their build quality is great, and they’re built to last. The body is rubber-coated, which allows for a comfortable and firm grip, and you get some shock resistance as well. They’re built for outdoor use, even in some more extreme conditions such as mountaineering or watersports. The fact that they’re dust-proof and waterproof means that they’ll survive whatever you decide to throw at them.
One of the best features of the Athlon Optics Midas ED was the ease and precision of adjusting the focus. It smoothly and accurately adjusts across a wide range of focal depths. Some models, like the Nikon Prostaff 5, focused very quickly, but this often translated to loss of detail at distance, or basically, the smooshing together of anything more than a couple hundred feet away into one focusing position. This sounds confusing, but makes sense if you think of a focusing knob the way you might a volume control. Less rotation between silence and loudness means you can get between the extremes quickly, but you may not be able to get to precisely the level you want; on the other hand, a volume knob with too much rotation will take forever to adjust. With binoculars you want a happy medium that focuses fast but allows for granular accuracy. In other models, even within the same brand (e.g., Nikon Prostaff 7S), this focusing issue was less noticeable, and they performed well in this regard. In still others, such as the now-discontinued Opticron Explorer WA Oasis-C pair, the knob was sluggish, requiring a good crank around several times to focus on anything near or far.

Incidentally, one odd problem with the Nikon Monarch 5 (our pick in our previous binoculars guide) was a loud, rubber-on-rubber squeaking sound the focusing wheel often made when coming into contact with the rubber housing. I would have thought this was a random, fixable issue, but judging from online reviews, others complained about this too. The problem seems limited to individual pairs, so send yours back if they start doing this.
Combine Nikon binocular performance with the extreme speed and ranging technology of a 1900-yard laser rangefinder and you have Laser Force, Nikon's 10x 42mm Rangefinder Binocular. Quite simply the single optic solution for serious hunters who depend on both their binocular for picking out distant animals and their rangefinder for getting the exact distance before taking the shot. Featuring ED (Extra-low Dispersion) glass and Nikon's ID Technology to compensate for incline or decline angles, Laser Force puts ranging precision, optical performance and rugged performance within your reach.
The EL only has one downside, and it's a big one: price. Listing for $2,888 these bins cost as much as a used car and are more of an investment than a purchase. However, if you're a serious birder or wildlife watcher that wants the absolute best, or you're embarking on a once in a lifetime safari, these bins will undoubtedly elevate your experience.
Back in the clarity section, we talked about how alignment can affect the detail you see through a pair of binoculars. Some alignment issues can be hard to diagnose. Small alignment issues can only show up with specially calibrated equipment. One can look at the overall construction quality and hope that if they follow tight tolerances on the rest of the production, then optics should follow suit.
The Vanguard Endeavor ED are lower-powered binoculars with a 10x magnification. Along with a 114m field of view, this Vanguard model is best suited for faster-paced action and outdoor activities. They have one of the largest objective lens diameter of the binoculars we reviewed, so they’ll perform better in low- and poor-light surroundings, making them a good pair of hunting binoculars on early mornings.
If binoculars aren’t 100% indispensable to bird watching, they’re pretty close. For almost any bird that crosses your path, a good pair of binoculars will show you fine details, make colors pop out of shadows, and improve your chance of identifying what you’ve seen. For most bird watchers, binoculars soon become almost an extension of their bodies.

Lens coatings are films applied to lens surfaces to reduce glare and reflections, increase light transmission and contrast, and help make colors look more vivid. Any light reflected is light that never reaches the viewer’s eyes, so by eliminating reflections, the image ends up being brighter and sharper. Coatings, in general, are good, provided that the coatings do something. It’s easy to put a cheap coating on a lens to give it a cool-looking orange tint, but the coating might not do anything to improve image quality. If you aren’t able to test a pair of binoculars before buying, the best you can do is research the brand, look for user reviews, and ask questions before you buy.


When you hold a pair of binoculars at arms length and look into the lenses there will be two circular points of light. These are the exit pupils, determined by the magnification and diameter of the front lens. These points of light should fit inside your pupils, Since not everyone pupils expand to the same diameter what size you need will vary. In general though, under 30 years old you want 7 X 35. Older eyes will need more like 7 X 50.
Ranging Performance: The ranging performance describes how far a model can accurately range a target. The maximum range listed by the manufacturer is the farthest the model can return accurate results under ideal conditions. This is important because it makes up half of the purpose of the device, and different hunting styles require different maximum ranges.
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.

Is there a best binocular for astronomy? We could point you to one of the best in the Fujinon 25X150 MT or it's sibling with 40X magnification. They both have terrific optics, but neither will do any good if it's not used. Your OpticsReviewer proposes that, aside from ensuring you have fundamentally good optics in good housings, the best astronomy binoculars are the ones that are used and help a person to learn more about the celestial bodies around this globe.
Magnification: This determines the extent to which you can make faraway objects appear closer. Experts suggest that most people find a happy medium—enough magnification to identify birds from a distance, but not so much that unsteady hands become more noticeable and the viewing area becomes too small. Higher magnification is also less than ideal when you’re tracking a moving target, which will probably be the case when you’re birding.

The good news is that the true technological improvements in binoculars over the past few years have come not in gimmicky features, but optics. Whereas 20 years ago you might have needed to spend $500 to get decent, waterproof binoculars from a factory in the Midwest, now the recent manufacturing boom in China has brought us increasingly cheaper versions of familiar products, resulting in a crush of nearly identical binoculars—more than 2,000 models right now on Amazon, for example—most of them featuring similar designs.
For outdoor activities like bird-watching, hunting or even viewing a sports game from a high-up stadium seat, these binoculars provide an excellent view. Top Ten Reviews lauds these binoculars for their durability and ease of use. "Add this to its unparalleled viewing experience, and you have the best binoculars we reviewed," Top Ten Reviews states. While these binoculars do provide an impressive view, with12x magnification, they're also heavier than average, weighing in at 36.2 ounces (1 kilogram). Eyeglass wearers won't have a problem using these binoculars; you can adjust the eye-relief distance to make these fit with or without glasses on. These binoculars are fog-proof, waterproof and super-durable, so you don't have to worry about damaging them with outdoor use. And according to Top Ten Reviews, these binoculars work great in low-light situations, so you can use them for nighttime skywatching as well as daytime sport.
