The Fury’s rangefinder reticle is similar to the one you’ll find in a normal rangefinder. Like the Laser Force and Fusion, these binos utilize a laser to acquire distance. If your target is at an odd angle away from you, the Fury employs the Horizontal Component Distance (HCD) to compensate for those angles and ensure you are getting precise distances.
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.
Olaf Soltau, a member of the New York Chapter of the Audubon Society, shared his experiences and opinion: “I use Swarovski EL 10x42s. But it took years before I felt ready to move up from 8x to 10x. For beginners, I always suggest 8x40. Think Goldilocks: not too strong, not too weak, not too heavy, not too flimsy. It's simply the best compromise. Higher magnification makes the image too shaky and the birds too hard to find, especially for beginning birders. Lower magnification simply doesn't bring the birds close enough. There are, of course, exceptions. 10x40s are OK if most birding takes place in wide open spaces like grasslands and coastlines, where the birds are often far away. I used 8x40s for years until my hand had gotten steady enough and my bird-finding-through-binos skills had become good enough for 10x40s. Another exception: People who don't have the physical strength to carry 8x40s around all day long can opt for 8x30s, but that means sacrificing image quality.”
Complementing lens coatings are prism coatings, which increase light reflection and improve image brightness and contrast. While many manufacturers may use standard reflective coatings, the upper echelon of prism coatings is called dielectric coatings, which allow almost 100% of the light through the prism, resulting in brighter high-contrast images.
My use is 50/50 day/night celestial/terrestrial. I have found in the past when using a 10×50 I’ve always wanted some more distance/zoom. I have never used a larger power than this and am happy with the reviews of the Meade. portability is not an issue and neither is the weight, i will be using them hand held. budget is the driver and the most bang for buck. Given the above would you recommend the Meade 15×70?
For many people the ideal compromise will be a mid sized binocular which have objective lenses of around 32mm. These are becoming increasingly popular, and there are many good arguments in their favor. Whilst it is true that larger objectives can theoretically deliver brighter, higher resolution images, with magnifications of around 8x, it is actually quite hard to detect a qualitative difference between 42mm and 32mm objectives. In my opinion, at 8x or 10x, the quality of the optics and their coatings is far more important than the size of the lenses.
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!
Higher power doesn’t necessary mean better bigger; the amount of magnification you’ll want depends on the end use. Low-powered binoculars from 6x to 10x magnification work great for most outdoor activities and sporting events where you’re keeping up with fast-paced action (a larger lens size and increased field of vision are also recommended for keeping up with the action). Higher magnifications are best for longer distances and less mobile objects, like landscapes or the night sky (and a larger field of vision is not necessary).
In general astronomical binoculars should not really be thought of as a substitute for a telescope, rather you should think of them as something to be used along with your scope, especially when you want to get a wider field of view and see more of the sky at once. But to give you an idea of what kind of things you can see, the observations below were made whilst using the great value Celestron SkyMaster 25x70 Binoculars on a night with an almost full moon and a fair amount of light pollution:
We’ll finish off this list with a pair of binoculars with rangefinders that are a bit different than the other offerings above. The binoculars we’re discussing are ATN’s BinoX-HD, 4-16x. You might think they aren’t exactly a budget offering, but they’re very far from the premium ones by Nikon and Carl Zeiss. Factor in the functionality they offer, though, and you might be inclined to change your mind on the “budget” part. When you try to take a look at some traditional night vision devices online, you will find that many quality options tend to be upwards of $2,000. Many people don’t want to spend that amount of money on such a product, and you can’t really blame them. The BinoX-HD break that pattern, by providing Gen1 night vision, with a price that’s a fraction of the competition’s.

Having said that the gap between the leading tier of €1,000 plus binoculars and some of their more affordable competition is closing. Optical technologies, techniques and components pioneered by premium European manufacturers have become more widely available and affordable, and production standards in the far east have improved to the point where manufacturers are mass-producing some remarkably good optics.
The Pentax Papilio II 8.5 x 21 and the Nikon ProStaff 8 x 25 ATB are both “chunky” compacts with offset eye-pieces (as opposed to the more common roof prism design), and may be more comfortable for some users because these pairs can be easier to grip. Unfortunately, the Papilio took far too long to focus (though on the plus side, it’s marked “extremely-close focusing,” and it is), and though the Nikons were satisfactory, I found myself getting slight eyestrain when focusing on distant objects, like ducks floating on a lake.
2. Start with a small, easy-to-use size. Don’t buy a huge pair of binoculars to start with! Unless you mount them on a tripod, they’ll shake and make your view of the heavens shakey, too. The video above – from ExpertVillage – does a good job summing up what you want. And in case you don’t want to watch the video, the answer is that 7X50 binoculars are optimum for budding astronomers. You can see a lot, and you can hold them steadily enough that jitters don’t spoil your view of the sky. Plus they’re very useful for daylight pursuits, like birdwatching. If 7X50s are too big for you – or if you want binoculars for a child – try 7X35s.
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.
Eyecups on the binoculars ensure that your eyes will be at the correct distance, but if you wear glasses, you can't get your eyes as close to the lenses, so you need to adjust the eyecups to ensure that even with your glasses on your eyes are the correct distance from the ocular lenses. Binoculars with a longer eye relief are ideal for those who wear glasses as they basically project the image further beyond the ocular lens, giving you plenty of room to play with. So if you wear glasses, you should be looking for an eye relief of at least 15mm, to see the full image full image.
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.
