What Makes Marine Binoculars Different?

When it comes to understanding your binoculars, there are generally six essential points to remember. Let’s take a closer look at each of the characteristics listed above.

Field of view

The breadth of a field of vision is usually measured in feet or meters from a fixed location. It defines the horizontal picture seen while gazing through a binocular without moving the same.

The field of view is measured in feet when it is 1000 yards or meters away. Each degree of vision is equivalent to 52.5 feet at 1000 yards.

It is important to remember that the magnification and field of view are inversely related. When magnification rises, the area of vision of the marine binocular diminishes, resulting in a narrower picture. And so, it is necessary to have the broadest field of view possible while using binoculars.

Magnification and Objective Lens Diameter

Binoculars are classified by numbers, like, for example, the 7×50. While the first number represents the magnification, the second number represents the lens diameter.

At sea, it is clear that the higher the magnification, the more information we can receive via our eyes. However, it should be noted that as the magnification rises, it becomes more difficult to maintain an item in focus, causing it to blur as the brightness decreases. 

A higher lens is needed to enhance the brightness of the picture to avoid a decrease in brightness. As a result,  cautious magnification of 7×50 marine binoculars and an objective lens diameter of 50mm are recommended.

Waterproof/Fog proof Binoculars

Given the severe environment in which binoculars are used, they must be waterproof and fog-resistant. 

High-end marine binoculars are waterproofed by sealing all of the openings with O-rings. It helps to keep dust and moisture out of the binocular body. However, although waterproof, they are inherently fog-proof; water may still condense on the lens’s exterior.

More so, some excellent binoculars include a waterproof function that lasts until a particular submersion depth and duration, as stated on the binocular.

Focus

Marine binoculars are usually produced in two configurations: center and individual focus or fixed focus. 

The most popular kind of binoculars on the market are the center focus binoculars. It has a central focus knob that can adjust the focus on both eyepieces simultaneously.

This conventional binocular is helpful if you share it with the rest of the crew as everyone can adjust focus according to their needs.

On the other hand, the majority of the maritime people prefer individual eyepiece focus. 

Compass

A built-in compass is included in a few marine binoculars on the market. While looking through the binoculars, they show a superimposed compass right below the picture.

An integrated compass is extremely useful when watching a vessel from a distance and knowing its orientation. From a vessel’s safety standpoint, the compass function is beneficial.

Nitrogen Filled

Nitrogen prevents moisture from entering the binocular. It means you can use your binoculars whether it’s raining or when you’re swimming or diving in the water. Other impurities such as dust, dirt, fungi, and corrosion are all resistant to nitrogen, which keeps your binoculars extremely clean from the inside. 

Moreover, nitrogen ensures that no fungus or corrosion grows in your binoculars when mistreated, such as when kept in a wet area without any protective measures. Thus, many marine binoculars filled with nitrogen are very sturdy and safe from these elements. 

FAQs

What are the best binoculars for boating?

The best marine binoculars mentioned above on the top 7 list will perform adequately for this need. They are budget-friendly, waterproof, and provide clear pictures, making them best for sailing and boating.

On the other hand, you can also look at the binoculars in the Steiner Marine Binoculars. It can see objects under challenging conditions, making it one of the best for boating. 

What zoom is best for marine binoculars?

The majority of marine binoculars will feature a zoom factor of seven times. An 8x magnification works for some individuals, but much more than that makes looking at any item ineffective. 

A 7×50 is the typical profile among most marine binoculars. The magnification combined with the relatively big lens provides for excellent light transmission. It facilitates seeing buoys and viewing details for navigation.

What does FMC mean?

FMC is an abbreviation for fully multi-coated optics. It refers to the lens, which offers the greatest protection against glare and reflection on the water.

It is an essential component of marine binocular profiles. Although FMC can not guarantee stunning pictures on its own, only high-end products do.

Conclusion

There is no one-size-fits-all answer in selecting the best marine binocular for your trip. Your needs and budget mainly determine the one you end up purchasing.

However, investing in decent marine binoculars that many people have previously tried and tested is undoubtedly a smart choice.

Try the top choice, the Bushnell Marine 7×50 Waterproof Binocular. They are long-lasting, sturdy, and of excellent quality. If you require something less expensive, the Barska Deep Sea 7×50 Waterproof Marine Binoculars will be ideal.
