The Ultimate Guide to Binoculars

Since their inception, binoculars have helped people of all ages see objects that aren’t clearly visible to the naked eye, personal and up close. Whether you’re using them as a scope for star gazing or taking high-quality shots to document your digital nomad lifestyle, the right model of binoculars can be an excellent accessory to own.

Despite their widespread availability, what are the must-have features in a binocular, what makes one model different to the other, and how to achieve great views with a new purchase is information that’s still mysterious to potential customers. That’s why we decided to create an ultimate guide that educates you on all the bits and bobs of buying and using this handy accessory.

Let’s dive deep into the world of binoculars, shall we?

 

What to look for in binoculars?

 

 

 

 

Binoculars are a handy tool for off the grid survival.  They have a range of traits and features. The important ones include:

 Size

Binoculars generally come in three sizes: full, medium, and compact. Common full size specs are 8*42, 10*50. These binoculars collect more light and are great for using on a boat (or serious wildlife watching). Mid-sized ones are 7*35 and 10*32, and are better for sports and wildlife use. Compact binoculars are the lightest ones with specs of 8*25 and 10*25. They’re the most portable but may become problematic during extended use.

 Magnification

Lower magnification allows you to get up close with the target or object. However, there’s an opportunity cost of going too low. For example, getting a close up view of something means you can’t completely see the environment around the object. The recommended magnification, therefore, is 8x or 10x. Also, it’s important to note that a magnificent power above 10x is going to amplify the hand movement of the user, making it challenging to obtain a steady view.

Field of view

This refers to the area that you can view at a certain design. For example, a binocular model with 250 ft. field of view could allow you to see an object 1000 yards far. Once the object gets bigger in view, you’re going to see less of the environment around. A wide view is preferable for spotting wildlife such as birds. However, you’ll need to compromise on the magnification power as it has a trade-off with field of view.

Prism style

The viewing accessory comes with various prism styles. These are important, as a binocular without prism would show everything upside down because of the ample rays passing through its lenses. The most popular prisms are “porro” and “roof.” Thee former offer excellent optics, but are a bit heavy in terms of weight. The latter are compact and slim, which makes them a good choice for travel. The downside of roof-prism binoculars is that they’re costlier to buy.

Objective Lens Diameter

Another important feature to consider is the diameter of the binocular’s objective lens. It’s depicted in millimeters. 35mm is the objective lens diameter for binoculars with 7*35 objective lenses. These define how much light can pass through the gadget, with bigger objective lens diameters able to capture more light and provide a clearer view in low-light environments.

Exit pupil

This implies how bright the binocular will show an object when it’s placed in low lighting. The greater the number, the brighter is going to be the image. Bigger exit pupils also make it convenient to see the complete picture of an object if the user’s hands shake or move. In most instances, exit pupils are calculated by dividing the objective lens diameter by the binocular’s magnification. Look for binoculars that have an exit pupil number above 7, as anything below will block the light from reaching your pupils.

Relative brightness

Like exit pupil, relative brightness defines how bright an animal or object will appear to the user’s pupils. Objects will appear brighter when the relative brightness of the binocular is high. The number is calculated by doing a square of the number for exit pupil.

Eye relief

This shows the particular distance between the user’s eyes and each eyepiece as the entire “field of view” can be seen. Longer eye reliefs, obviously, provide greater comfort by enabling users to hold the gadget away from their face. This specification is most relevant to those who wear eyeglasses. Pro tip: make sure to take off the “rubber eyepiece collar” before using the binocular if you’ve been wearing eyeglasses for a while. An eye relief that’s greater than 10mm should do the trick.

 

Construction materials

 

This is another factor that defines the comfort and durability of the binocular. Materials that are of the highest quality last longer, and are a bit costlier than other binoculars. For instance, lightweight binoculars often include magnesium alloy and have durable materials. Affordable models, on the other hand, feature plastics and resins. Although the latter are difficult and less prone to bumps and knocks, they weigh more. At the end of the day, the material you go with will depend on the quality of the image you wish to achieve and and your overall budget.

Fog and Water-proofing capabilities

Waterproof binoculars often contain “O-rings” that wick the moisture away. Also, they keep small debris from entering the binoculars lens. Fogroof models also exist for those who’re always moving between temperatures.
