The Leica Geovid HD-B is an advanced model with a versatility that can handle target shooting and hunting. The model features automatic adjusting that alters ballistics based on the atmospheric conditions when in use. It also has fantastic optics with the ability to view targets clearly at over 1,500 yards. Its field of view is 300 feet even at 1,000 yards.
I had use of a pair of Mavens customized to these specs while bobbing off a Norwegian glacier in an open boat, trying to pluck a white-tailed eagle out of the storm-laden sky as it wheeled and dipped off a rock face that was the color of slate gray, with cloud cover roughly approximate. It ducked in and out of the shadowed, crenellated cliffs and I tried not to barf. Eventually, I locked onto this magnificent predator with a sharpness that was uncannily vivid. I can still see its fish-hooked, kitchen-yellow beak and almost hear the snap of its wing beat. At a scant 16.5-ounces, the B.3s are some of the lightest premium binoculars on the market, yet at a mid-range price. Baring catastrophe, we’ll be lifelong pals.
Eye-cups are related to the eye relief as they keep the distance from the oculars to our eyes, but also help keep stray light away from your eyes while using binoculars. Many eye-cups are made from rubber and can roll up or down depending on whether you use lasses or not. The problem with these is that the constant rolling causes the eye-cups to break. Another type are eye-cups that slide rather than roll, but these can be hard to keep in place. The third type are eye-cups that twist up and down and so they can be left at any position from all the way up to all the way down, some even have click stops at regular intervals with the eye relief distance for each stop marked on the cup so you can get the perfect eye relief for your vision. (importance 8/10 if you uses glasses not hugely important if you don't)
Ballistic Functions: Ballistics curves are essential for getting proper information from the rangefinder unit, and customizable ballistics information is ideal. Many units come with pre-programmed ballistics charts that also allow the user to enter their own specific information. Some models even feature automatic adjustment of the ballistics curves based on changes in the atmosphere.
This complete kit includes everything you need to become familiar with night sky wonders. Even the most inexperienced "newbie" stargazers will soon be able to point out constellations, distinguish planets from stars and see craters on the Moon with the help of the 10x50 Binocular Stargazing Kit. Binoculars provide a great hands-on introduction to astronomy, and the 10x50 pair in this value-packed kit will wow the whole family with 10x power views of the Moon's cratered surface, as well as celestial showpieces like the Andromeda Galaxy, glittering star clusters, and so much more. Their convenient portability make binoculars ideal instruments for exploring night sky curiosities while on road trips, family campouts, and even during casual walks on clear evenings. Of course, the 10x50 binoculars can also be used during daylight hours for high-power terrestrial views of birds, wildlife and scenery. They're great for getting closer views of sporting events from bleacher seats too! The Orion 10x50 Binocular Stargazing Kit is filled with other useful astronomy goodies too. The included Orion Star Target Planisphere is an easy-to-use star chart wheel you can use year-round to see what stars and constellations will be visible. The Star Target will show you where stars and such can be found in the night sky from hour-to-hour, so you can easily plan when to go outside to observe your favorite constellations. You can read the StarTarget planisphere at night without disrupting dark-adapted vision with the included RedBeam Mini LED flashlight, which emits red light. Unlike standard white light flashlights, the red light from the RedBeam Mini LED won't degrade your ability to detect details in the dark. A perfect gift for beginning astronomers, the complete Orion 10x50 Binocular Stargazing Kit can provide night after night of family fun under the stars.
Most believe that Canon was the first company to have image stabilized binoculars due to very good marketing and bringing the price down to within reach of the consuming public, even if it's a long reach! Their introduction in 1997 was based on the work they had done for years in stabilizing video camera images. It quickly caught on and image stabilized Canon binoculars have many devotees. While the Canon technology doesn't seem designed to stabilize the larger movements encountered on boats/ships, speeding cars/trucks, and airplanes/helicopters, it does well with hand movements such as those often associated with health and age. The engagement of the stabilization mechanism and electronics is said to often result in a somewhat softer image which lacks the crispness found in Fujinons. We anticipate publishing a review of the Canon image stabilized binoculars.
Pros: Testers noted that the Vanguard Endeavor ED were easy to operate and to focus. A wider objective lens of 42mm brings in a good amount light for better viewing in low-lit situations, and a close minimum distance of 2.5m allows you to see fine details in birds, plants and insects. A weight of nearly 24oz is average, and these binoculars are tripod compatible as well.

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.

If you are interested in Astronomy and can’t afford the telescope at the moment (we all know how expensive they are) you can definitely buy binoculars to fulfill your interest. It is always better to invest in high-quality Astronomy or Stargazing Binoculars rather than investing in a cheap Telescope. Also, Binoculars have some advantage over the telescope like they provide a wide field of view, they are portable enough to carry, and we can use both our eyes to observe which feels more natural to us. In fact, binoculars are also referred as “The first Telescope” and even a seasoned astronomer always keeps one by the telescope.
Whether you’re bird watching, hunting, or even just taking an exploratory hike in the wilderness, a good pair of binoculars is one of the most useful things you can bring along with you. Though they’re not immediately thought of as a necessity by those who don’t have a direct need for them, binoculars can provide some true entertainment and fascination in the outdoors. If the fishing is slow, for example, checking out the herons across the lake or scanning the treetops for hawks is a great way to pass the time waiting for a bite. But in order to use them for situations like the above, you first have a pair. And, as with anything else, you should always research binoculars before you buy them. Read on for an elementary guide to binoculars for the outdoors.
Notably both the Nikon Monarch 5 8x42 and the Vortex Diamondback 8x42 also earned scores of 8 out of 10 in our clarity testing. This is impressive considering that both modles list for less than $300. While these model both have slightly more edge blurring than the top scoring products, they generally provide a super crisp, immersive image, allowing us to easily pick out all the minute, defining features of our bird models.
We’ve already mentioned coatings several times, and they really do transform the performance levels of any binocular. Almost all binoculars on the market today will have some kind of anti-reflective coating applied to at least some of the air-to-glass surfaces to improve light transmission, compensate for the aberrations inherent in any optical design and enhance image resolution, colour fidelity and contrast.
Eric Lind, Center Director of the Audubon Constitution Marsh Center & Sanctuary, in Garrison, New York, prefers 8x binoculars and says, “8-power gives you a little bit more than 7-power. I’ve tried 10x, but they were difficult to hold steady.” Eric uses an older pair of Zeiss 8x42 binoculars. “10x,” he says, “might be more appropriate for shore bird viewing from the beach.”
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.
Welcome to Optics4Birding, the birding experts’ choice since 1992. We’re passionate about birding, and we’ve hand-selected a range of birding optics and accessories that are perfect for getting the most out of this engaging pastime. Optics4Birding has optics for any budget, from beginners to serious enthusiasts, researchers, and birding tour operators. Of course, we carry brands that are well-respected in the optics industry - brands like Zeiss, Leica, Nikon, Swarovski, Vortex, and many more. We are authorized dealers for every manufacturer we sell.
I know that some museums, like the Louvre or Musee d'Orsay, are well lit - while some parts of Versailles, cathedrals and churches like the Sistine Chapel - are a bit dim (almost dark)...so if you can handle a bino larger than a compact (up to 25mm objective lens diameter) you may want to think about upping the size to a 30-40mm to help make the view brighter if you know the rooms will have challenging lighting.

We loved the eyecups on the Swarovski and Zeiss models. Both use threaded eyecups that twist in and out and have very conspicuous stopping points, so you can be sure both eye cups are set on the same depth. The Lecia bins also use threaded eyecups, but the stopping points aren't as solid, and we often had trouble getting both cups set to the same depth. This was particularly annoying when sharing the bins amongst multiple testers with different eyecup preferences, as it took much more finagling to get the eyecups to an acceptable and even setting.
Pick a magnification. Deciding between 8x and 10x binoculars is a personal choice. In general 10x are better at distance birding. But it usually also means a narrower field of view, a slightly darker image in low light, and more noticeable hand-shake. An 8x gives you a smaller image that’s wider, brighter, and easier for finding and following birds.
What is also interesting is they accept the standard, 1.25-inch astronomical filters to enhance your views of the Moon, planets nebulae and other celestial bodies. Other features include fully multi-coated lenses, quality BAK-4 prisms, individual focus for precise adjustment. They are fully waterproof and nitrogen-purged to prevent any fogging up. They're also backed by Zhumell's 25-year warranty.
Recommendation: always strive for the best optical quality your budget will stretch to, and look for binoculars that deliver sharp, high-contrast images, with lots of detail and a large focal “sweet-spot” and good depth of field. If you’re interested in watching insects pay particular attention to the close focus distance. Look out for HD or ED glass in the objective lens — but bear in mind that non-ED binoculars from premium manufacturers can, and often do, outperform ED optics from some other brands.
Open or Closed bridge refers to the center portion that connects the two optical tubes on roof prism binoculars. Typically, the center hinge and focusing mechanism will be enclosed in the housing. While this strengthens the hinge and mechanism, the closed bridge prevents your hands from wrapping all the way around. An open bridge will usually have the focus mechanism close to the eyepieces and another stabilizing section toward the objectives, with the middle section left open. This not only enables a full wraparound grip, but it also cuts the overall weight of the optic.
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.
It was during my training into becoming a field guide (safari guide) that I learnt in any detail some of the southern hemisphere's star constellations, it was also the first time that I had ever really looked at the stars through binoculars. Even though I was only using my compact Steiner 10.5x28 Wildlife Pro's which are far more suited to looking at wildlife than the stars, I was amazed at just how many more stars you can see through binoculars than you can with the naked eye, so much so that it became difficult to pick out the constellations because of all the "new" stars that I could now see.
Telescopes are big. Even little ones are bigger, heavier and longer than most binoculars. So telescopes need to sit on tripods or rocker-boxes for stability. A hand-held spyglass might have been good enough for Captain Kidd, but every modern navy uses binoculars. Angling a long tube up toward the sky makes the shake problem even worse; your extended arm wiggles the front objective lens. Binoculars can lock in tightly to both your eye sockets and your hands are close in to your face for more stability. [Related: Best Telescopes for Beginner: A Buying Guide]
