Binoculars may look like a simple pair of equipment, but they have a number of key features that can change how they perform in a given environment or activity. It’s so important to know where, when, and how you’ll use your binoculars before buying. In this binoculars buying guide, you’ll get our expert advice on the following:
There are a number of factors to consider when choosing a pair for yourself. Before we get too far into these details, here’s a general overview of the anatomy of binoculars:
Magnification power is largely what binoculars are known for, which is their ability to magnify things. Magnification power is always the first number in a binoculars’ size (styled as AxB). The higher the number, the number of times the image in your lens is magnified in comparison to the naked eye. For example, a magnification power of 8 would be 8x the power of an unassisted eye.
Always remember that a higher magnification number/power means you’ll have smaller fields of view when you’re choosing a pair of binoculars.
Objective lens diameter is always the second number in a binoculars’ size (styled as AxB). The objective lens is the outermost lens of the binocular, and its diameter determines how much light your binoculars gather. The more light, the brighter the image.
While ‘size’ tends to refer to the binoculars’ overall combined magnification power and objective lens diameter, there’s also the physical size and weight to consider. Most binoculars fall into the following physical sizes:
Compact binoculars: Less than 30mm objective lens diameter, they are made slim and lightweight, so they’re perfect for slipping into a hiking or hunting pack.
Mid-size binoculars: Between 30mm and 40mm objective lens diameters, these are a great compromise between weight and clarity, giving you crisper images without too much heft.
Full-size binoculars: Greater than 30mm objective lens diameter, they take in lots of light for high-quality, super-crisp imaging.
Looking for just one pair that is the best general performing binoculars or only have room in your budget for one size? Pick up a pair sized to 10x42! This size can take a variety of species and terrains.
Field of view is the width of a viewable area, seen from 1000 yards away. A narrower field of view means you’ll have to scan back and forth more often. It’s a great spec to use if you’re trying to decide between two pairs since the field of view tends to vary dramatically between types of binoculars.
Close focus is the distance between your binoculars and the nearest object that can remain in focus. If you want to see something nearby and (relatively) up close — such as a backyard butterfly, a bird on a telephone wire, or an elk near your hunting stand — pay attention to this specification.
Exit pupil is a measurement of the light that reaches your eyes through your binoculars. The higher the number is, the brighter the images you’ll see. This is more important for low- to no-light situations, and less important in bright daylight.
Eye relief refers to the distance between your binocular’s eyepiece and your eye when your binoculars are properly calibrated — meaning the entire field of view is visible. This is a key specification if you wear glasses, as eye relief does vary between the different makes and sizes of binoculars.
Glasses wearers should look at binoculars that allow for a minimum of 15mm or more for eye relief.
Binoculars are an essential part of a hunting gear checklist and do more than just help you spot your game. They also help you locate other hunters, survey the land, and conserve energy — since you’re not hiking around to look at things or check snares.
While most hunters will want to find a pair that splits the difference between power and weight, as with all hunting gear, figuring out how to choose binoculars for hunting depends on the game you’re after.

While birds certainly are small, they also move around a lot. Eight-power magnification gets you a wider field of view, making it easier to learn how to track a bird’s movement and location in your lenses. |

Hiking | On the trail, size, and weight means everything, so make sure you find a pair that doesn’t take up too much space in your pack (or make it too heavy). Rubber coating or anti-scratch lenses can withstand tougher terrain. |

A higher, 10-power magnification can help make sure you pick up on all the details. A wide field of vision will also help make sure you’re not missing any crucial passes, so a mid-size pair of binoculars can also work great. |
