One of my best purchases for my camera (weighing 81oz with my birding lens attached) was a shoulder sling strap. Several manufacturers produce a harness strap for binoculars that distributes the weight across both shoulders, frees up your hands to hold onto other gear and keeps them securely against your chest: For more, take a look at this guide on the Best Binocular Harness for Hunting.

Tripod Adapters As mentioned before, binoculars with magnifications of 10x and higher are hard to hold steady, especially if they have large objectives. Large binoculars sometimes have a built-in tripod mount that makes it easy to mount them on a tripod. Sometimes a tripod adapter is required. Typically, full-sized binoculars have a plug that unscrews from the front of center hinge. The adapter screws into its place and mounts on most quick-release plates or tripods. Some tripod mounts are simply a small platform on which to lay the binocular and hold it in place with an adjustable strap.
Age is the single most important factor in choosing a pair of binoculars. Although with age a person’s exit pupil tends to get smaller; that is, 5mm after age 50, one should determine his or her exit pupil. This is usually done by trial and error. If you do it in the dark, you cannot see what you are doing when holding up a millimeter ruler to your eye in front of a mirror. You can try a dimly lit room however. Sky Publishing use to sell a device for measuring one’s exit pupil.Another factor affecting your exit pupil is your observing environment. If you observe from the city or the suburbs, light pollution will affect your exit pupil and will not allow it to fully dilate as if you were under a country sky. For instance, if you observe with a 7 x 50 pair of binoculars under a city sky, this is like observing with a pair of 7 x 35 binoculars. Why? Because your pupil is not fully dilated to take advantage of the extra exit pupil or circle of light being projected by the 7 x 50 binoculars. What is the exit pupil of a 7 x 50 binocular? Answer. 7.1mm. Divide 50mm the aperture of the binocular

Birders tend to gravitate toward the 40mm range for their binoculars. Binoculars with 40mm, 42mm, or 44mm objectives serve as a good medium compromise between low-light capability and portability. Objectives smaller than 35mm will lead to a more portable package at the expense of light gathering, and a 50mm or larger objective will give you a very bright image along with, potentially, the aforementioned sore neck and shoulders.
Recently, there was a post published on this site that covers the best binoculars in the market for hunters (at an affordable price) as well as how you should go about picking the one that suits you most. No doubt, it’s highly informational and if you are planning to get a binocular, I highly recommend you to take a look at that post first. And you probably realized, it didn’t cover the rangefinder aspect extensively.

Compact binoculars have a tough job. Their glass must be clear enough to transmit images through relatively small objective lenses, and their sized-down controls need to be tight and precise to work within the smaller frame. This Leupold gets those details right. The controls are nice, the image is bright and big for the compact platform, and we really liked the close focus. The Tioga got the highest durability score in the category, and it has a lifetime transferrable warranty should you need it.
With both Bow and Rifle modes to offer, VSI (Various Sight-In) zeros, ARC (Angle Range Compensation), and Matrix Display Technology available in the palm of your hand, you’ll never be found wanting again. The optics have been dressed up with additional, patented technologies to ensure image quality is never compromised. With the best price on its back, you’ll be sure to hit your target every time!
The magnification and objective of a binocular are always complimentary. The range of a rangefinder binocular also depends on these two aspects. You might have seen the binoculars being denoted by a set of numbers such as 7×20 or 10×42. What it denotes is the magnification and the diameter of the objective lens. For example, if the binocular is denoted by 7×20 it means that 7x is the magnification and 20 are the diameter of the objective lens. The magnification requirement depends on the purpose of your purchase. If you have bought it to take it to the movies, the ideal magnification would be anywhere from 3x to 5x. If the purpose something like sports, 7x would fair perfectly. But for hunting the best option would be 10x magnification. But one thing you have to keep in mind is that the field of view reduces with increase in magnification. The field of view of a 7x rangefinder binocular would be more than that of a binocular with 10x magnification. Also, it will be difficult to hold a rangefinder binocular which 10×42 for a long time as it will be heavy. The help of a tripod stand can be used in such cases.
The larger SkyMaster models (80mm and 100mm ) have been designed by Celestron to meet the special demands of extended astronomical or terrestrial viewing sessions and include features like enhanced structural reinforcement to the main binocular body. and an integral super rigid photo tripod adapter to enable easy attachment to tripods and other fixing devices.
The Celestron TrailSeeker binoculars are great for gathering light and delivering fantastic optical resolution with their 42mm lens and 8x magnification, the industry standard for a good pair of binoculars. While some of the image edges might suffer from blurring, these binoculars will still give you a wonderful and wide field of view for less than $200. And with their lightweight magnesium alloy body, you know you’re going to get something durable, waterproof, and high-quality for the outdoors or in a stadium setting.
When most people think of amateur astronomy, they picture a dad and son using a telescope perched out in the middle of a soccer field, but you can do it just as well from a fire escape when you look through these decidedly massive binoculars. They let me see details on the surface of the moon I thought were reserved for Apollo astronauts. Get them and you’ll see starlight brighter than ever before. You might even catch a distant meteor or comet streaking through the sky. Even in nearly pitch-black night, their massive 100mm diameter lenses gather an abundance of light. Do not bring them on distance hikes — they are nearly 10 pounds and far too heavy.
The angle and distance display has the ability to be set to one of four different intensities, which can be a pretty useful feature if you intend on using the binoculars in various lighting conditions. When you have a moving target, there’s the ability for a continuous measurement, and it lasts up to 8 seconds. Accuracy of the measurement is incredible, with a very small margin of error – at 100 meters or less, it’s accurate to 0.1 meters, which is very impressive.

Hopefully you found the information included above to be useful. You can use all of the information to streamline your decision-making process as to whether or not you want to purchase rangefinder binoculars, and also use it to better educate yourself about this technology – as well as others. They are definitely incredible tools, but may or may not be useful in your specific circumstance or situation.


While I'm not familiar with a 60x60 binocular, I can extrapolate some issues you would have with it. First, your exit pupil will be just 1mm, which is prohibitively small - especially if you're observing in challening light like dawn or dusk, or trying to see into heavy brush. For reference, an average person's pupil is dilated to about 2-4mm in bright light, and 4-8mm in the dark. Additionally, your field of view will be quite narrow, so finding and tracking birds and wildlife will be tricky. Finally you will need a rock-solid support system as there is virtually no way to hold something of that magnification and size steady enough to enjoy the view.
There is an adage that goes "the best pair of binoculars is the one you use." If yours aren't comfortable to hold, carry, or look through then you aren't going to use them. Things like rubberized coatings on the barrels, indentations for your hands and thumbs, an open bridge, comfortable interpupillary distance, padded straps, adjustable eyecups, weight, size, and eye relief can all affect how comfortable a pair will be. All of these measurements are very subjective and will differ between individuals. For instance, not everyone's eyes are set the same distance apart, so everyone will be most comfortable with a slightly different interpupillary distance. The amount of eye relief can be a big concern for someone with glasses and of little concern to others.

Stars in a cluster all formed from the same gas cloud. You can also see what the Pleiades might have like in a primordial state, by shifting your gaze to the prominent constellation Orion the Hunter. Look for Orion’s sword stars, just below his prominent belt stars. If the night is crisp and clear, and you’re away from urban streetlight glare, unaided eyes will show that the sword isn’t entirely composed of stars. Binoculars show a steady patch of glowing gas where, right at this moment, a star cluster is being born. It’s called the Orion Nebula. A summertime counterpart is the Lagoon Nebula, in Sagittarius the Archer.
Our small army of volunteers rated the models on a 1 to 5 scale for a variety of factors, including clarity, brightness, focus response, and eye relief. (For a fuller explanation of our methods, see the below story on how we made our rankings.) For the sake of consistency, we reviewed 8x32 (pronounced “eight by thirty-two”) or 8x42 optics. Most birders prefer 7- or 8-power binoculars because they’re bright and have a wide field of view, making it easier to find birds and to follow them in flight. Optics with objective lenses—the glass at the fat end of the tube—larger than 42 mm are heavier, and those smaller than 30 mm, while lightweight, aren’t bright enough to show detail in poor light. 
Adjust the Binoculars for Your Eyes - This final adjustment is the most important because it will deliver the sharpest image. Your eyes are different from each other, so each of your binoculars' eyepieces can be focussed separately to be perfect for both of your eyes. They do this with a diopter setting. The eyepiece which can rotate independently of the binocular body is the one with the diopter setting. See how to do this in the section below.
If you're concerned about size, you can drop down to a pair of Zeiss (top of the line brand) 32mm Terra ED's. This one is on sale, so supplies are limited...but they're one of the best out there. ED glass, fully multi-coated, wide angle of view, water and fogproof, and an extremely short close focus distance. I highly recommend these if you can get them while they last. https://www.bhphotovideo.com/c/product/1116044-REG/zeiss_523206_9906_000_terra_binocular_10x32_edition_under.html
“Took these binoculars to see Cavalia Odesseo from the nosebleed section and I must say they gave me an excellent view of the horses and acrobatics. I could easily see the violin soloist, the Spanish guitarist, and the enchanting vocalist behind the shrouds on the balconies. I will never watch a stage performance the same way again. I find that at a certain distance, I didn’t have to adjust the focus as often as I had expected. The focal sweet spot is pretty large. There is a mild chromatic aberration when viewing in daylight hours against the light, but this goes away when I fine tune the focus. For the price, these binoculars can’t be beat.”

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 trade-off from above model is a smaller field of view which is greater with the 15×70 binoculars when using by hand, but for astronomical you will need to use a tripod anyway. This model has an adapter to attach to a standard camera tripod – just make sure you get one that is high enough for your height so that you don’t need to stoop too much when using.
As we have discussed, binocular manufacturers are on a never-ending quest to provide us with a perfect image. Some of the common issue’s consumers experience is loss of brightness and color, depth of field issues, chromatic aberration, fringing, and crispness. Many of these problems are compounded in challenging light environments such as in shady woods or sunrise/sunset.
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.
These binoculars provide the widest field of view of all the binoculars tested by Top Ten Reviews. This means that the Action EX Extremes "are ideal for situations in which you want to track fast-paced movement," like bird-watching or sporting events, Top Ten Reviews states. With a relatively low magnification of 7x, these binoculars won't allow you to see quite as far as Celestron's SkyMaster binoculars do. However, the lower power helps to eliminate the shaky images caused by small hand movements. But what these binoculars lack in magnification, they make up for with optical quality. "Nikon Action EX Extreme produced some of the best images out of all the binoculars we reviewed," Top Ten Reviews states. However, these are best used for daytime observations. The binoculars have 35-mm objective lenses, which is a relatively small setting and means that these binoculars won't catch as much light in low-light settings. The Action EX Extremes are also fog-proof, waterproof and durable enough that you can use them outdoors without worrying about damaging them.
