There is no single criterion for figuring out the best binoculars. The binoculars which work for a birdwatcher will not be sufficient for a soldier. To select the best hunting binoculars or best binoculars for birding, there are particular basic principles which should be followed. They will help you in selecting the best binoculars for your requirements.
The very best binocular for you is that which fits inside your fingers well. It should provide you with a good area of vision. It should be able to withstand adverse climate circumstances and allow you to see with clarity objects each close to and far. They should be durable, and simple to carry.
There are numerous prestigious companies, which manufacture binoculars for consumers. Their prices can vary according to the model. The models which offer higher fields of vision are usually more costly than those providing lesser fields of vision. Nevertheless, certain countries have started producing quality binoculars for simply one-eighth with the cost charged by big names within the area. So if you are not brand-conscious you are able to conserve about six to 7 hundred dollars around the purchase of high-quality binoculars. Those who are searching for the best binoculars may not be able to discover them in division stores, as salespersons frequently do not know a lot about binoculars. Therefore, they’re not in a position to suggest you the best model suitable for you. You may try out the stores that only promote binoculars and telescopes. If such stores aren’t available inside your town or neighborhood, you are able to attempt an online store like Amazon and eBay.
How to choose the best
Binoculars are the world’s most used optical tool (right after glasses). There are many kinds of binoculars, Infra Red binoculars, night vision binoculars, waterproof binoculars and so on. Binoculars mostly are used for hunting, birdwatching, and for astronomy. We will review all these types, so YOU can select which suits you best. We will give honest reviews about the binoculars, so you can choose wisely before buying !
Binoculars are labeled with numbers, such as 8×40, 7×35 and so on. Some binoculars use numbers like 10-20×70, this means that binoculars are zoom binoculars. The first number 8x40 means, that the binocular has 8x zoom. Which means that looking trough an 8x binocular, the object will be 8 times closer than it really is. Many people like to think that the bigger number is better, well not always that is true. If you will choose a magnification that is bigger than 10x, you will have problems with shaky/unsteady view. Because as the magnification grows, the more sensitive the view gets. Since people have shaky hands, looking trough a binocular which has big magnification will cause the view to shake. If you are planning to buy a 10x or bigger magnification, then consider buying an tripod, which will support the binocular, and will deal with the shaky view.
The other number is 8x40. This means that it has a 40mm lens (both lenses) width. The size of the lens will affect performance. If the lens is bigger it will allow more light beams to go trough. Which means that the image will be sharper and brighter than for example 8×25. But if the lens is bigger the binocular is also bigger, and it’s heavier. So before buying please consider if you want a compact and small binocular, or a big one, but with greater sharpness. The size of the lens does not affect the field of view.
Field of View (FoV)
Field of view is the territory which will be visible to you, trough the binocular. Imagine a fence 1000yards away. If a binocular has a field of view of 250 feet at 1000 yards, you will see 250 feet of the fence. If the field of view is 150 feet at 1000 yards, you will 150 feet of fence.
Field of view is determined by the magnification. If the magnification is 10x, it will have a better look, but the field of view will be lower, than an 8x binocular. And the second thing is the eyepiece which is in the binocular. You can also buy wide angle binoculars, but they are more expensive than standard eyepiece binoculars.
Exit Pupil is the width of the light beam, that leaves the binocular. You can measure the exit pupil, by dividing the 2 numbers – 8×40 = 5 exit pupil, 7×35 = 5 exit pupil. Most times 5 exit pupil is totally enough. But binoculars such as marine binoculars, or binoculars that are used by the military have exit pupil of 7+. Because if the exit pupil is bigger the view is steadier, and it’s easier to look trough the binocular, for example driving in a car, or flying in a chopper.
Eye relief is the range which determines how close your eyes must be to the eyepieces of the binocular to see the complete field of view. If your eyes are not close enough to the eyepieces, then you will not be able to see the complete field of view.
Waterproof binoculars prevent fogging from the inside. Binoculars do fog from the outside, but if it fogs from the inside, then it’s almost impossible to clean it. If you are using your binocular near water, then it is strongly recommended to buy waterproof binoculars.
Waterproof binoculars will prevent contact with any form of water (rain, fog). But they will not prevent dirt and dust to enter your binoculars. That’s why sealed binoculars is a must if you are sure, that you will be in an dusty area. Dust can damage your binoculars quite bad.
