Of course, we know the best way to make the right choice is to get enough information about it, so before you get one at the store, look through the lenses to find the optical performance and durability of the pair of binocular there are in your local store. Clearing that from the air, below are the common considerations when getting the best binoculars that will work for you.
How to Choose Binoculars for Hunting?
Terms You Need to Know
People often ask, what do model number spec in binoculars mean? The specs tell the strength and the size of the binoculars. For example, in the 8 x 42 binoculars. The “8” means the power of the magnification, and the “42” tells the diameter of the binoculars in millimeter of the lenses. The objective lenses can give you an insight into the size of the binoculars and also how much light can be gathered.
Understanding these numbers means that you know what you want to use that for. Like if a binocular is suitable for stargazing, birding, bird hunting, to apply for a moving boat.
Bird watching: with the assumption that you are not already concerned about the size and the weight of the midsize and full-size models.
The 10x magnification is helpful for looking at small animals and they provide a broader view that’s essential when birding. They should also be water-resistant, and they should have the anti-fog feature to prevent the binoculars from fogging up in a cold area.
Binocular sizes are broken down only into a compact, a midsize, and the full-size categories; the categories are associated with the size of the objective lenses. It is also important to note their might still be because of the variation in the optics, construction and the design can imply that models that have the same size of the objective lenses can differ when talking about size and weight.
- Compact binoculars: 30mm (8 by 25, 10 by 28)
- Midsize: between 30 mm to 40mm ( 10 by 30, 8 by 32)
- Full size: any more than 40mm (8 by 42, 10 by 50 )
Compact can fit in a backpack, but the midsize models produce brighter images and are much more comfortable when you hold it for an extended period of time. Though a massive set of binoculars can be difficult to hold for a protracted period of time.
The most common type of magnification is the eight and the ten magnification. However, there are still models that have lower and even higher forms of magnification.
The eight power binoculars give a full field of view. The ten power binoculars provide a close and more detailed look, e.g. the 8 x 25, 8 x 32, and the eight by 42 all have the same magnification strength. The focused object is going to appear eight times closer than they would with the ordinary eye.
It very easy to think that a better binoculars to pick is a binocular with higher magnification, but the irony to this is; the higher the magnification, the more problematic the binocular. Any binocular with the magnification strength that is greater than ten will not guarantee steady viewing. So those variants can be deficiency when you are on a boat or platforms that move.
Objective Lens Diameter
The diameter of the objective lens also contributes to the amount of light the binoculars are able to gather. When comparing two binoculars with the same relative specifications. The pair that has the more massive pair of objective lenses will gather more light, meaning that the image on that binocular is brighter. Also, when the binoculars have higher quality, they also have more vivid images.
When the exit pupil has a higher number, they have brighter images. In areas with low light, the higher the number, there is relatively better viewing. And it is also easier to consistently maintain the full picture of an object even if the hands move or shake.
To estimate the exit pupil, divide the diameter of the objective lenses and the magnification number. For example, the exit pupil for the eight by 42 is obtained by dividing 42 by eight, which gives 5.25mm. It is a sum total of the quantity of light that is going to reach the eyes. The eyes pupil size at bright light is 2mm and 7 mm when in total darkness.
- When in low light are it is good to use an exit pupil of 5mm. these are the times during dawn and dark or where there is dense shade, here having a high pupil number is good
- During the bright day viewing the exit pupil size will not matter because all binoculars have exit pupils that are more than 2mm
This is the distance through the eyes and the eyepiece when the fields of view are still within sight. This is essential if you wear glasses.
You will find a feature in most binoculars, which allows you to adjust the eyepiece, which will let you set the eyepiece for maximum eye relief value. This is usually regulated by winding rubber eyecups or by rolling a collar to make the eyepiece shortened.
The prisms are the optical elements that direct light from an image passing through the binoculars, and into your eyes, there are the older prism binoculars that feature large barrels in front that are attached to the eyepiece. The newer roof prisms have attached the objective lenses and the eyepieces. There is a difference in appearance, but there is no difference in optical quality. However, the roof prisms make for a smaller and lighter binocular.
Field of View
The magnification power has an effect on the field of view no matter whether you’re hunting for a monocular or a bino pair. When the magnification power is lower, the field of view is expanded, and it also narrows the field of view when the magnification power is higher. Having a narrow field of view make it harder to locate small animals like birds when one is going birding.
Because of the lower field of view, there is less light, which means that the images are darker factors like the eyepiece design; the field of view spec is one to check when getting an accurate picture. The spec states the amount of area that you can view at one glance, 1000 yards away from your position
Binocular Lens Coating
The most popular is the rubber kinds that do not provide protection during a heavy crash. They will shield from minor bumps and the bruise. They are essential when using binoculars outdoors.
Waterproof and Water-Resistant Binoculars
Are you going kayaking, aboard a train, or in the rain? Water-resistant or weather-resistant binoculars can come in handy. You also have to be aware when getting water-resistant binoculars that the manufactures would identify any level of water-resistant to be waterproof. However, there might be a distinction.
- Waterproof binoculars often use 0 rings for sealing out moisture; this can survive quick plashes, but they do not survive an extended submersion. Binoculars that have this level of protection would be typically labeled as waterproof when referring to the model name
- Weather-resistant binoculars do not have the full protection that the waterproof protection provides but they can handle a light rain, but they can not survive immersions, whatsoever
One thing to note is that binoculars have the potential to fog up when moving from a cold environment to a warm environment. This is as annoying as it can be damaging to the binoculars if the moistures become trapped inside.
Manufacturers would purge the air inside the binoculars with nitrogen. Because nitrogen lacks moisture, nitrogen will not condense. This makes sure that the internal lens surface does not fog up; however, there is no guarantee for the exterior lens surface.
Tips for Choosing a Binocular
- One thing to note is that binoculars are expensive, especially the night vision binoculars. Be careful when spending your hard-earned money in buying something. The best thing the manufacturing company can do is to give a warranty. The warranty represents how confident a manufacturer is of their product.
- Before settling on a binocular, pick the binoculars up and feel it notice the weight and the feel of it in your hands.
- Price also matters. Get help from a buying guide and check the price beforehand!
- Use the standard glass, extra-low dispersion glass, or the high definition glass.
- At the end of the day, the design of binoculars brings a question. Check the manufacturer and the reputation they have.
- Before going to the market implant a budget in your mind to prevent you from overspending.
Now you know how to choose binoculars, it’s high time to take a great journey by viewing through each lens.
