For travel enthusiasts, a good pair of binoculars can make all the difference in fully experiencing and enjoying the natural beauty of a new location. Whether you’re birdwatching, sightseeing, or just want a closer look at something in the distance, having a reliable pair of binoculars can enhance your travels. However, with so many options on the market, it can be tough to know which binoculars are best for travel. In this article, we’ll discuss some key factors to consider when choosing binoculars for your travels.

Types of binoculars

Roof prism vs. Porro prism design

Binoculars can be designed with either roof prisms or Porro prisms, which affect the shape and size of the binoculars as well as the image quality.

Roof prism binoculars have a more compact and streamlined shape, as the prisms are aligned in a straight line and the barrels of the binoculars are parallel to each other. This design allows for a more compact and lightweight body, making them suitable for travel. However, roof prism binoculars may not have as good image quality as Porro prism binoculars due to the additional reflections caused by the prisms.

Porro prism binoculars have a more traditional and familiar shape, with the barrels of the binoculars angled away from each other. This design allows for better image quality, as the light travels in a straight path through the prisms and there are fewer reflections. However, Porro prism binoculars are typically larger and heavier than roof prism binoculars due to the larger prisms and the angled barrels.

It’s important to consider the pros and cons of each design when selecting binoculars, as the type of prism can affect the image quality and the size and weight of the binoculars. Roof prism binoculars may be more suitable for travel due to their compact size, while Porro prism binoculars may be preferred for activities that require a higher level of image quality, such as bird watching or stargazing.

Compact vs. full-size binoculars

Binoculars can also be classified as compact or full-size based on the size of the objective lenses and the overall size of the binoculars.

Compact binoculars have smaller objective lenses, typically in the range of 20-30mm, and are generally more portable and easier to carry around. They are suitable for a wide range of activities, including sightseeing, bird watching, and wildlife viewing. However, compact binoculars may not have as good image quality as full-size binoculars due to the smaller objective lenses, which gather less light and result in a dimmer and less clear image.

Full-size binoculars have larger objective lenses, typically in the range of 32-50mm or more, and generally have better image quality due to the larger objective lenses. They are suitable for activities that require a higher level of image quality, such as bird watching or stargazing. However, full-size binoculars are larger and heavier than compact binoculars, which may make them less convenient to carry around.

Key Features to consider

Objective lens size

The objective lens size of a pair of binoculars refers to the diameter of the lens at the front of the binoculars, which is typically measured in millimeters. The size of the objective lens plays a key role in the performance of the binoculars, as it determines how much light the lens can gather. A larger objective lens allows more light to enter the binoculars, resulting in a brighter and clearer image. This is especially important in low light conditions, such as dawn or dusk, when there is less light available.

However, it’s important to note that larger objective lenses also make the binoculars larger and heavier, which may not be ideal for travel. Compact binoculars with smaller objective lenses are typically more portable and easier to carry around, but may not perform as well in low light conditions. It’s a trade-off between image quality and portability, and ultimately it depends on your specific needs and preferences.

Magnification and field of view

The magnification of a pair of binoculars is indicated by a number, such as “8x” or “10x”, and refers to the amount that the image is magnified. A higher magnification may provide a clearer and more detailed image, but also has a narrower field of view and is more sensitive to hand movement. A lower magnification may have a wider field of view and be less sensitive to hand movement, but may not provide as much detail.

The field of view is the width of the area that the binoculars can see at a distance of 1000 yards. It is typically measured in feet or meters at a distance of 1000 yards. A wider field of view is helpful for tracking moving objects or scanning a wide area, while a narrower field of view may provide more detail but may be more difficult to use for tracking moving objects.

It’s important to consider both the magnification and field of view when selecting binoculars, as they both affect the usability of the binoculars. A higher magnification may be desirable for certain activities, such as bird watching or stargazing, while a lower magnification may be more suitable for other activities, such as sightseeing or wildlife viewing.

Coatings and lens quality

Coatings on the lenses and prisms of a pair of binoculars can greatly improve the image quality and contrast of the binoculars. Multi-coated lenses and prisms have multiple layers of coatings on them, which helps to reduce reflections and improve the transmission of light. This results in a brighter and clearer image with better contrast and color accuracy. Single-coated or uncoated lenses and prisms may not perform as well in terms of image quality and contrast.

In addition to improving image quality, high-quality coatings can also improve the durability and scratch resistance of the binoculars. Optics with coatings that are applied using vacuum deposition or ion-assisted processes tend to be more durable and resistant to scratching than those with coatings applied using other methods.

It’s important to consider the coatings and lens quality when selecting binoculars, as they can greatly affect the performance and longevity of the binoculars. Higher-quality coatings and lenses may come at a higher price, but they can provide a better overall experience and may be worth the investment.

Focus system

The focus system of a pair of binoculars refers to the mechanism that is used to adjust the focus of the lenses to bring the image into sharp focus. There are two main types of focus systems: center focus and individual focus.

A center focus system allows you to adjust the focus of both barrels of the binoculars at the same time using a single focus knob or lever. This is generally easier to use, as you only need to adjust one control to focus on an object. A center focus system is suitable for most types of general use, including bird watching, sightseeing, and stargazing.

An individual focus system, also known as a separate focus system, allows you to adjust the focus of each barrel separately using a focus knob or lever for each barrel. This allows for more precise focusing, as you can fine-tune the focus of each barrel to match your eyesight. An individual focus system is generally preferred by those who need to wear eyeglasses or those who have a significant difference in the vision between their two eyes. However, it may be more difficult to use and may require more time to focus on an object compared to a center focus system.

Durability and waterproofing

Durability and waterproofing are important factors to consider when selecting binoculars for travel, as you may be using the binoculars in rugged or wet conditions.

To ensure durability, look for binoculars with a sturdy metal housing or those that have rubber armor or other protective coatings. These features can help to protect the binoculars from bumps and scratches, and may also help to improve grip. It’s also a good idea to choose binoculars that have been tested and rated for durability, such as those that are rated as “rugged” or “military grade”.

Waterproofing is also an important factor to consider, especially if you plan on using the binoculars in wet or humid conditions. Look for binoculars that are rated as waterproof or water-resistant, as these can withstand being submerged in water or exposed to rain or other wet conditions. Waterproof binoculars are typically sealed with O-rings or other types of seals to prevent water from entering the internals of the binoculars. Water-resistant binoculars may not be suitable for being submerged in water, but can withstand light rain or moisture.

Price ranges

Budget options (under $100)

There are a wide variety of budget-friendly binoculars available for under $100. These binoculars may not have the same level of image quality or features as more expensive models, but can still be suitable for general use and casual activities such as sightseeing or bird watching.

Budget-friendly binoculars may have smaller objective lenses, which can affect the image brightness and clarity. They may also have simpler focus systems and fewer coatings on the lenses and prisms, which can affect the image quality and contrast. However, they may still provide a satisfactory experience for those who are looking for a basic pair of binoculars for occasional use.

Budget-friendly binoculars may not be as durable or waterproof as more expensive models. They may also not have as wide a field of view or as much magnification, which can affect the usability of the binoculars. However, for those on a tight budget or those who only need a basic pair of binoculars for occasional use, budget-friendly options can be a good choice.

Mid-range options ($100-$300)

These binoculars may have better optics, coatings, and focus systems than budget options, and may be more durable and waterproof. They are suitable for a wide range of activities and can be a good investment for those who use their binoculars frequently.

Mid-range binoculars may have larger objective lenses, which can improve image brightness and clarity. They may also have more advanced coatings and focus systems, which can enhance the image quality and contrast and make the binoculars easier to use. In addition, mid-range binoculars may have more durable construction and be rated as waterproof or water-resistant, which can make them suitable for use in rugged or wet conditions.

You want to consider features and performance of mid-range binoculars when selecting them, as they can vary greatly. Some mid-range binoculars may offer excellent value and performance for the price, while others may not be as good of a value.

High-end options (over $300)

High-end binoculars are generally the most expensive and offer the best image quality, features, and durability. They are suitable for serious enthusiasts or professionals who need the best performance and are willing to pay a premium for it.

High-end binoculars typically have the largest objective lenses, which can provide the brightest and clearest images. They may also have the most advanced coatings, prisms, and focus systems, which can further enhance the image quality and contrast. In addition, high-end binoculars are often built with the highest-quality materials and are rated as waterproof or water-resistant, making them suitable for use in any conditions.

High-end binoculars may provide the best overall experience, but they may not be the best value for those who do not need the highest level of performance or who do not use their binoculars frequently.
