When choosing the best tools for long-distance viewing, there are some categories that everyone considers – guns, knives and fire starting implements, for example. One of the tools that can literally mean the difference between life and death, but are often overlooked in rucksacks and bug out bags, are binoculars.

When you choose the best survival binoculars, you’re giving yourself an edge in any situation. Whether you’re identifying a potential threat, or tracking down resources, a pair of high-quality, durable binoculars are an important part of your tools cache.

Lets first start with some common binocular specs which might help in your decision. If you’d like to get right to the list, you can jump to the list now.

Common Binocular Specs

Below are a few common binocular specs. Consider these all-around good, general purpose binoculars.

  • Full-Size: 8×42
  • Mid-Size: 7×35
  • Compact: 8×25

Common Binocular Uses

Below are a few common binocular uses and the most common binocular type.

  • General: 7×35, 8×42, 10×50
  • Outdoor: 7×35, 7×50, 10×42
  • Bird Watching: 8×42, 10×42, 10×50
  • Boating: 7×50, 7×42, 8×42, 10×42
  • Stadium Sports: 4×21, 8×25, 10×25
  • Concerts: 5×25, 8×25
  • Low Light: 7×50, 8×42, 10×50

Magnification Power

Binoculars are made up of two numbers (for example, 8×25). The first number represented is called the magnification power. In this example (8×25), an object would appear as though it was 8 times close than your natural eye.

In a real life scenario, if you were looking at an object which was 300 yards away, using binoculars with a magnification power of 8, the object would appear as if was only 37.5 yards away. You get 37.5 yards by dividing the actual yards (300) by the magnification power (8).

Objective Lens Diameter

The second number (25 in the example 8×25), is the objective lens diameter. These numbers are represented in millimeters; so, 25mm.

This number mostly affects the amount of light that is allowed into the binoculars. Obviously, the larger the diameter of the lens, the more light allowed in, thus the brighter view of the object. A higher objective len diameter is particularly helpful in low-light situations.

Exit Pupil

The number which represents how bright an object will appear is called the exit pupil. This number is also represented in millimeters. To find the exit pupil you divide 25 by 8. This gives us an exit pupil of 3.125mm.

Like lens diameter, it is best to have a higher exit pupil for lower light scenarios. Exit pupil dimensions are less important during daytime viewing as your struggle to find enough light is less.

Relative Brightness

Realtive Brightness is often paired with exit Pupil. Meaning, they both measure how bright an object will appear, particularly in low-light situations.

In order to find the relative brightness, you would “square” the exit pupil number. Lets take our 8×25 example. The exit pupil was 3.1mm. 3.1 multiplied by 3.1 is 9.61. Therefore, the relative brightness of an object with an 8×25 binocular would be 9.61.

Again, the higher the number, the better viewing in low light situations.

Eye Relief

Eye relief is the distance between the eyepiece of the binoculars and your eyes when the whole field of view is visible.

This factor is most useful for those who wear glasses. A common best practice is to look for an eye relief of 11mm or more if you wear glasses.

Field of View

Field of View is represented by the amount of area you can view 1,000 yards away from you.

A higher magnigfication power typically results in a much more narrow field of view. Whereas, a lower magnification power typically results in a wider field of view.


Most, if not all binoculars, come with a central turn-style knob jut between the two eyepieces of the binocular. This allows you to adjust the focus on an object.

It is also common to adjust the focus of the eyepieces independently. This is to accommodate the focus and clarity differences between each of your eyes.

Prism Type

Binoculars are made using one of two types of prisms; Porro or Roof.

Binoculars made using Porro prisms are often times larger in size and less expensive.

Binoculars made using Roof prisms are often smaller, more compact. These binoculars are typically more expensive do to the complexity and precision to build.

Lens Coating

Much of the light which passes through your binocular is reflected away. In order to reduce this reflected light, coatings are applied to the lens.
