There are many aspects to consider when choosing hunting binoculars. Besides magnification, you should also consider the size of the Objective lens and the exit pupil. Another factor to consider is the price range and the purpose for which you want to use the binoculars. Generally, a hand-held pair with a magnification of seven to twelvex will be adequate.


When choosing a pair of hunting binoculars, it is important to consider how far the magnification will reach. Higher magnification will allow you to see more detail, but this will also reduce your field of view. Higher magnifications will require you to pan the lens.

When choosing a pair of hunting binoculars, you should also consider the terrain you will be hunting in. If you plan to hunt in a heavily wooded area, a lower magnification is preferred. Lower magnifications will reduce heat waves, which will allow you to see the deer clearly even in extremely hot weather.

Choosing the magnification of your hunting binoculars will depend on what you want to see in the field. If you are looking to watch animals and birds from a distance, you will want a lower magnification. A higher magnification will decrease your field of view and reduce the clarity of your images.

If you are wearing glasses or sunglasses, it is important to choose binoculars that have good eye relief. This allows you to raise your binoculars quickly without straining your eyes. An eye relief of 15 to 20 millimeters is ideal. When choosing a pair of hunting binoculars, you should also choose a pair with a tripod socket so that you can mount your binoculars on a tripod.

The magnification of your binoculars is one of the most important factors in choosing the right pair. High magnification makes it easier to see larger animals and objects, but it also narrows the field of view and makes the image shake. Also, it is important to remember that the higher magnification doesn’t necessarily mean the better.

Objective lens size

When it comes to hunting, you’re going to want to choose a binocular that’s going to be able to provide you with the best possible view. The size of the objective lens is an important consideration, and there are a few different sizes available. In general, the size of a binocular’s objective lens is measured in millimeters. A typical size is 25-28mm for compact models, 30mm for mid-size units, 40mm for full-sized binoculars, and 50mm or higher for very long-range models. The size of the lens is directly related to the amount of light it can gather. A larger lens will gather more light, and therefore will provide better images in low-light situations.

The objective lens size of a binocular determines the magnification level. A higher magnification will allow you to see details you may not otherwise notice. However, a higher magnification will also result in a heavier binocular. You should also be aware that binoculars are easier on the eyes than spotting scopes or monoculars. The reason is that the brain processes details better with two eyes. This means that a 40x optic will provide more detail than a 20x optic.

Another important factor is the field of view. While higher magnification makes it easier to see more detail, it also limits the field of view and makes it difficult to track targets. Thankfully, there are a number of ways to compensate for this, including a larger objective lens size.

The exit pupil size of a binocular is another important consideration. If the objective lens is smaller than your eye, then the image will appear more dim and will require more light to be viewed clearly. In order to calculate this size, divide the magnification by the objective lens diameter. A 10×50 binocular has a 5mm exit pupil, while a 7×42 pair will have an exit pupil of 6mm.

Exit pupil size

The exit pupil size of a pair of hunting binoculars is a very important factor to consider. The larger the exit pupil size, the more light will be able to enter the binocular. The exit pupil size is calculated by dividing the objective lens size by the magnification factor. A larger exit pupil allows a larger amount of light to be visualized and a clearer image.

The exit pupil size of hunting binoculars is usually larger than the pupil of the human eye. A smaller exit pupil will give a dim image. The exit pupil size is a key factor when comparing binoculars and other optical instruments, especially when you’re using them in poor light conditions.

A good rule of thumb is to buy binoculars with an exit pupil of about 2 to 5 mm. This size is close to the size of a human pupil, which is generally two to five millimeters wide. This should be sufficient for most hunting conditions.

Another important factor to consider when comparing exit pupil sizes of hunting binoculars is your eyesight. Larger exit pupils are ideal for hunting in low light, since they allow more light to enter the eye. This, in turn, means brighter optics. Also, consider other factors such as edge-to-edge clarity, field flattening optical system, and ergonomics. Also, don’t forget to look for custom builds to enhance your hunting binoculars.

Exit pupil size also affects brightness and contrast. A larger exit pupil allows more light to enter the eye and produces a brighter image.

Rubber coating

One of the most common features of hunting binoculars is a rubber coating on the lenses. A rubber coating prevents fogging and increases protection in case of a drop. This is an important feature, especially if you plan on going out during the cool morning hours. Rubber coating on binocular lenses also makes them more comfortable to use.

The quality of binocular lenses largely depends on the coating. Without a coating, light would bounce off the glass, creating glare and poor contrast. A thin chemical film helps eliminate reflection, such as magnesium fluoride. This increases light transmission and reduces the amount of light lost, which results in brighter and clearer images. Multiple films can increase this effect and limit reflected light to 0.25% to 0.5% of the glass surface.

Other important features include multilayer coatings and a roof prism design. The latter offers better durability and compact size. Rubber armor also provides a non-slip grip and is tripod-adaptable. Crossfire HD binoculars from Nikon are designed for serious outdoor enthusiasts. Their 42mm objective lenses and 10x magnification provide high resolution and edge sharpness. They are also waterproof.

A warranty policy is another important feature of a good binocular. Some manufacturers will offer a warranty to repair or replace damaged binoculars. A warranty from a reputable company can also protect your investment. For instance, Swarovski offers a 10 year warranty. This is a testament to their manufacturing quality. Another good option is Leica. The German company is known for its cameras and optical instruments.

The quality of an image is greatly affected by the manufacturing process. Some manufacturers use dielectric phase correcting to improve the clarity of the image. This process enhances contrast and reduces eye fatigue. Lower-quality binoculars may have chromatic aberrations, which create bluish or purple images. This effect is caused by light moving across the lenses at different speeds.


When purchasing a hunting binocular, be sure to check the warranty period. Some warranties will last for two years. Others may only cover the first year. If you have a problem with the binocular after that period, you can contact the manufacturer for a replacement. Some companies offer lifetime warranties, but there are some limitations.

The warranty period for hunting binoculars will differ depending on the brand. Some brands offer lifetime coverage for manufacturing defects, while others have limited warranties. Leica, for example, offers a ten-year warranty. This is a testament to their manufacturing skills. Leica also makes hunting binoculars, which is not surprising since the brand is well known for its cameras and optical instruments.

Steiner offers a limited lifetime warranty on most of their products. It covers mechanical and optical components, but does not cover intentional damage. Other brands, such as Carson, offer warranties that cover one or two years. Whether you purchase a new or used pair, it’s important to read the warranty period carefully. If you’re unsure about the warranty period, contact the company and request a warranty card.

A quality pair of hunting binoculars can help you identify game before it disappears. However, the right pair of hunting binoculars can vary from hunter to hunter. Some hunters will require higher magnification than others. For example, you may need high-magnification glass if you’re hunting in the west, while a lightweight pair might be enough for a whitetail stand.

The best hunting binoculars can come with a lifetime guarantee. Those that come with this warranty should be able to handle rough weather. In case of damage, you’ll receive a replacement or free repair.
