Best Hiking Binoculars Buyer’s Guide

Here’s a breakdown of key factors to consider when choosing binoculars specifically for hiking:

Choose According to Your Use

For hiking, versatile binoculars are recommended and a large field is appreciable. To observe subjects in detail, it is necessary to favor binoculars equipped with excellent optics, good magnification and fast focusing.

Avoid going over 10x magnification which could make your binoculars unstable in use. To observe birds at dusk, choose a model with a twilight index close to or greater than 20. A rubber coating will be ideal against falls as well as rubber protection for the eyes.

There are compact and easy-to-learn models specially designed for children. Models equipped with 8x magnification and a 21mm lens are sufficient to introduce them to observation.

Type of Prism

Binoculars operate using a prism system, which allows users to observe captured images without inverting them. There are two main types of prisms:

  • Porro prism: This design, although relatively old, is still used in high-magnification binoculars that are often priced attractively. However, this design can result in less solidity and luminosity because the light path is less direct.
  • Roof prism: This type of prism offers a more direct and thus brighter light path. Additionally, binoculars with a roof prism design tend to have reduced dimensions while maintaining excellent sealing and reliability.

Quality of the Lenses

The type of glass used in binoculars significantly impacts the quality of the images produced. There are two main types of lenses used in binoculars:

  • BK-7 borosilicate glass: This type of glass is commonly used in many binocular models due to its lower cost while still providing satisfactory image quality.
  • BaK-4 barium glass: Binoculars with BaK-4 lenses offer superior image quality performance, albeit at a higher price point compared to BK-7 lenses.

To ensure good contrast and sharpness in the images, manufacturers apply various coatings to the lenses of binoculars. These coatings include:

  • Fully multicoated
  • Multicoated
  • Fully coated
  • Coated
It is recommended to choose binocular models with multicoated or fully multicoated lenses for optimal image quality. Avoiding binoculars with uncoated lenses will also help guarantee a better viewing experience.

Magnification

On all pairs of binoculars, some indications correspond to the performance of the devices. We can find different binoculars, highlighting technical sheets where we will find mentions of 10 x 50 or 12 x 30. The first number of this technical information will indicate the magnification coefficient of the binoculars, which we could assimilate to “zoom”. A pair of 10 x 50 binoculars will allow you to view a subject or an object 10 times closer.

For hiking, a moderate magnification of 8x or 10x is ideal. Higher magnification might be tempting, but it can make images shaky and reduce the field of view (the area you can see at once).

The Lens Diameter

The diameter of the objective lens is indicated by the second number that follows the magnification on the datasheet of binoculars. Specifically, it represents the diameter of the front lens of the binoculars, expressed in millimeters. This measurement is crucial as it determines the quality of the image produced. Objective lenses function similarly to camera lenses: light enters through the lens, and the amount of light directly impacts the clarity of the image.

Understanding the value of lens size is crucial based on your intended use. If you plan to hike in areas with low light conditions, larger lenses will be beneficial for better light gathering. However, larger-diameter lenses will increase the weight and size of the binoculars. Therefore, opting for binoculars with large lenses may not be ideal if you primarily plan to use them in well-lit environments during daylight hours.

For day hikes, a lens with a diameter between 32 and 42 millimeters will be ideal. For nocturnal observations, you can favor larger objectives than those indicated for daytime observation.

The Diameter of the Eye Circle (Exit Pupil)

The eye circle, akin to a camera’s diaphragm, is the small circle of light observed at the back of binoculars. It is calculated by dividing the lens diameter by the magnification factor which ranges from 2 to 7 millimeters. This measurement determines how much light can be captured and directly affects viewing comfort. To optimize comfort, the eye circle diameter should be similar to your pupil diameter, which varies based on age and lighting conditions.

The Twilight Index and the Luminosity Index

The Twilight Index and the Luminosity Index are essential factors in choosing binoculars for different lighting conditions.

The Luminosity Index is calculated by squaring the diameter of the exit pupil. For instance, for 10×50 binoculars, the luminosity index would be (50/10)², or 25. A higher luminosity index indicates better light absorption, making binoculars more effective in low-light conditions. Therefore, binoculars like 5×50 would absorb more light than 10×50 due to their higher luminosity index (50 vs. 25).

On the other hand, the Twilight Index measures binoculars’ effectiveness in low-light conditions and is calculated by taking the square root of the magnification factor multiplied by the objective diameter. For example, 8×42 binoculars would have a twilight index of 18.33.

The Field of Vision

The field of view of binoculars refers to the width of the landscape observable through them at a distance of 1000 meters. It’s typically expressed in degrees or meters and is directly related to the magnification factor. Higher magnification reduces the field of view.

To calculate the field of view, multiply the magnification factor by the field width value. If the result is greater than 64, it indicates wide-angle binoculars. For instance, 10×50 binoculars with a 7° field of view would have a calculated field of view of 70.

The Focusing System

Focusing in binoculars involves adjusting the sharpness of the observed image to clearly visualize a subject. There are two types of focusing mechanisms in binoculars:

  • Central focus: This is typically done using a wheel or button located between the two barrels of the binoculars. It allows for quick and easy adjustment of focus for both eyes simultaneously.
  • Individual focus: This type of focusing is commonly found in binocular models designed for water sports or marine use. Each eyepiece has its own focus adjustment, allowing users to fine-tune focus independently for each eye.

Additional Features

For difficult and humid weather conditions, make sure the device is waterproof. This also ensures robustness which prevents entering water and fog into the optics. In the same way, if you want to use your binoculars in a difficult situation or a Hostile Environment, choose models with rubber-coated. This can limit breakage in the event of falls or shocks.

Finally, Eye Relief is important if you wear glasses. There are removable eyecups that can be adapted to binoculars. This will allow you to use the binoculars even with your glasses.

Preferred Brands and Manufacturers

There are options available at various price points based on their features and manufacturing quality. For top-of-the-range and more specialized models, brands like Nikon, Vortex Optics, Bushnell, Pentax, and Steiner stand out as leaders in the field of optical devices. These brands are known for offering the best quality and performance in binoculars, making them reliable choices for enthusiasts and professionals alike.

The Prices

The price of binoculars is indeed influenced by their technical specifications. Entry-level models can typically be found for around $100, while high-end and professional-grade models may exceed $1000 or even $1500. For good quality entry-level binoculars that prioritize excellent optical performance and refined manufacturing, you can expect to pay around $500.

FAQs

Which pair of binoculars should I choose if I wear glasses?

For users who wear glasses, make sure to choose models equipped with eye relief greater than 15mm.
