Binoculars

Binoculars are an optical instrument that allows you to see distant objects more closely. They are popular for birdwatching, wildlife observation, hiking, travel and other outdoor activities such as where seeing detail from afar is important.

A variety of binocular sizes and specifications are available to suit all purposes, from casual nature walks to serious wildlife watching.

How Do Binoculars Work?

Binoculars have lenses and prisms that enlarge the image but still enable both eyes to view it simultaneously. 

This results in a more comfortable viewing experience and helps to create a natural sense of depth.

The performance of a binocular in various situations depends on the level of magnification and the size of the objective lenses.

Understanding Binocular Numbers

Most binoculars are identified with two numbers, such as 8×42 or 10×42.

The first number is the magnification. An 8x binocular will make a subject appear 8 times closer than it would to the naked eye.

The second number is the diameter of the objective lenses, measured in millimetres. The bigger the objective lenses, the more light they let into the binocular and the brighter the image.

What Are Binoculars Used For?

Binoculars are used in many different outdoor activities.

Birdwatching

Birdwatchers often prefer binoculars that give a wide field of view and a bright image. The common models are 8×42 and 10×42.

Wildlife Observation

You can use binoculars to watch animals without disturbing them at a distance. Bigger objective lenses are especially helpful for early morning and late evening viewing.

Hiking

Lightweight binoculars are often favoured by hikers looking to minimise the gear they carry while still being able to observe wildlife and landscapes.

Travel

Compact binoculars are a popular choice for travel because they are smaller and lighter. They are small enough to fit in a backpack or carry bag easily.

Which Binocular Is Right For You

When buying binoculars, it is worth considering things like magnification, lens size, weight, field of view and weather protection.

The best binocular depends on how and where it will be used.
