You’re probably already aware that when you’re hunting in Hawaii, you’ll need to have a good pair of binoculars, but you may not be sure how to choose one. Here’s some information that will help you decide.

Exit pupil
The exit pupil is a measure of the diameter of a circular circle of light exiting from the binoculars. It is important to choose the right exit pupil size for your needs. In general, a bigger exit pupil will deliver a brighter image. This is especially important if you are hunting in poor light conditions.
A smaller exit pupil makes it harder to center the eye on the image. Furthermore, a smaller exit pupil can affect the flexibility of the eye. To find out the size of the exit pupil, you need to use basic math. First, you need to determine the size of the front lens. With a 7 x 50 binocular, you can calculate the exit pupil size to be 7.1 mm.
You then need to divide this number by the magnification. For example, a 3×10 binocular will produce a 5mm exit pupil. Similarly, a 4 x 25 binocular has an exit pupil diameter of 4.25 mm.
Another way to determine the size of the exit pupil is to compare the relative brightness. Usually, relative brightness is not a very good indicator of a binocular’s true brightness. Nevertheless, it is one of the simplest ways to determine if a particular optical instrument will do the job.
It is also important to consider the quality of the optics. If the lenses are uncoated, you may end up with a bright glare.
Magnification
When it comes to choosing binoculars, the magnification of the lenses is one of the most important factors to consider. It can have a big impact on your field of view and image brightness. You also want to make sure that your optics don’t fog easily and have a crystal-clear image.
Many people prefer to buy binoculars with 8 or 10 times magnification. These are great for open spaces and provide a wide field of view. However, they’re not as easy to hold steady when you’re looking at moving objects.
The more powerful the magnification, the more difficult it is to keep an image stable when the binoculars are shaken. Also, the larger the objective lens, the heavier the binoculars will be. Ideally, you’d want to find a pair with a small, lightweight objective lens.
For more serious wildlife watchers, you’ll want to find a pair that can magnify ambient light. This is especially important at dawn and dusk when the animals are more active. To do this, you’ll need a binocular with field optics.
High-magnification binoculars can be a challenge to handle, even for experienced users. They can be hard to hold still and can cause blurry images. If you need to be steady, a tripod system will be your best bet.
A common size for binoculars is midsize, which has a 32mm objective lens. Some smaller models can be found with 28mm objective lenses.
Field of view
A binocular’s field of view is the size of the circular area of light that is visible through it at a given distance. The larger the field of view, the wider the vision.
You can determine the field of view by looking at the target from different angles. For example, a 317-foot field of view means that at a thousand yards, you can see three-quarters of a mile away.
The field of view of a binocular depends on the magnification and the type of lens used. If you want a wider field of view, you can choose binoculars with bigger objective lenses. These can be heavier and absorb more light. This will provide a brighter image.
In addition, you should check for lens caps. Some products are made without these, so you should always put them back on after birding.
You should also consider how easy it is to focus on the object you want to observe. Binoculars that require fine adjustments will make your life harder. Unless you are a highly skilled hunter, it’s best to use a tripod. Also, don’t use binoculars with more than 12x magnification. It can cause your hand to shake, and the image will be blurry.
Finally, you should look for binoculars that have wide-eye relief. This will allow you to hold the distance eyepiece away from your eyes while still presenting a full field of view.
Coatings
Coatings are used on the inside and outside of the binoculars to improve their functionality. These coatings can help to increase light transmission, reduce reflection, and increase contrast.
There are three main types of coatings. Phase correction, anti-reflective, and infrared. Each coating offers a different level of performance.
Phase correction coatings prevent chromatic aberration, which is the difference in color between the different areas of an image. They also improve resolution and deliver accurate color reproduction.
Anti-reflective coatings also prevent glare, which can be an issue when using binoculars. Some models are coated with multiple layers of anti-reflective material. This increases the amount of light that reaches the eye, which results in a brighter image.
Having an extra layer of infrared coating can help to reduce glare and the haze that can occur in the atmosphere. An extra layer can cut infrared light by up to 95%, making the image appear brighter.
Coatings can also affect internal components, such as prisms. These prisms can increase the resolution of the images, which helps to ensure that you have a clear picture of the animals you are viewing.
The size of the objective lens is important. Buying a larger one can increase the light that reaches your eyes. It is best to have at least a 10 to 12 magnification power.
The coatings that are applied to the exterior of the binoculars are made to repel water, dust, and fingerprints. These materials are often rubberized.
Focus systems
When choosing binoculars for hunting, there are some things to consider. For example, the best binoculars for hunting are the ones that offer the right magnification. This is important because the higher the magnification, the more zoomed in the picture will be. Having the right binoculars means more accurate spotting.
The other thing to consider is the quality of the optics. Binoculars with good optics can enhance color fidelity, reduce color fringing and increase contrast. These are all important features for hunters.
The right pair of binoculars can make or break your hunting experience. Choosing the right size is also important. Whether you’re looking for a large or small pair, there are many different models to choose from.
If you’re a novice, it’s best to begin with the lowest magnification range. It’s important to find a balance between brightness and portability. Using a tripod can help you spot more games.
Another important factor to consider is the type of prisms. Different prisms perform differently, and this can have a big impact on your viewing experience. There are a few common types.
A phase-corrected prism, for example, will enhance resolution and contrast. Porro prisms, on the other hand, will produce a clear 3D image.
Finally, the weight of the binoculars is an important consideration. Larger binoculars require more glass and are heavier. Likewise, a larger objective lens is going to produce a brighter image.
Weight and size
Choosing a binocular depends on two factors. The first is the magnification and the second is the objective lens size. You want a binocular with a large enough objective lens to ensure bright and detailed images. This will add weight and bulk to your binoculars, but it will also enable you to see things far away.
For most people, the best magnification is 8x to 10x. However, there are some who like higher-power binoculars. They can provide details on animals that might be too far to see with a regular set of eyes. These are usually better for viewing in low-light situations.
Another important feature for hunters is the use of ED glass lenses. These correct chromatic aberration and reduce color fringing. ED glass lenses are hard to see, but they are a great option for long-distance viewing.
Most binoculars have adjustable eyepieces. These allow you to adjust the amount of eye relief for better viewing.
There are binoculars that have lenses that are fully waterproof. If you plan on using your binoculars while you are paddling, whale watching, or fishing, you should get a waterproof model. It is also a good idea to get one that has a built-in carrying case.
In addition to size, weight, and water resistance, there are other features you should look for in your hunting binoculars. Make sure to purchase a model that has a body harness and additional straps.
