Buyer’s Guide

We dedicate this section to the complete guide for buyers. We’ll cover some of the most important aspects of binoculars to consider before purchasing. Some helpful tips are included! There are several features you should consider when purchasing binoculars. These features include magnification, focal length, objective lens diameter, eye relief, field of view, and size.


The basic function of binoculars is to magnify objects in the distance. In other words, to bring them closer to you than they are.

If you want to easily learn the magnification power of a model, know that it’s right there in the name. With that being said, each model has two numbers with an ‘x’ between them. The first number is for magnification.

For the right binoculars, magnification of 7x or 8x is highly recommended. That’s because it will enable you to see distanced objects larger and the image won’t be distorted. Anything north of that will provide a shaky image. When you consider the fact that you’ll probably on a boat that shakes nonetheless, you’re apt to see almost nothing. Also, the field of view will be significantly reduced.

Focal Length

The focal length of binoculars is measured in millimeters. A longer focal length means that the binoculars can magnify distant objects better than shorter focal length models. However, you should also consider the size and weight of binoculars when selecting a pair. Lower-powered binoculars are lighter and easier to carry than high-power models. Many people prefer to use high-powered compact binoculars for fitness purposes because they are lighter weight than longer ones. A long focal length is also an advantage for bird watchers who like to observe birds from far away without disturbing them, or for people who like to observe the ocean waves at various distances without moving their position too much.

Objective Lens Diameter

The objective lens diameter of binoculars is measured in millimeters. Its size is related to the magnification, which means that the higher the magnification, the larger the objective lens diameter. The larger diameter means that more light enters the lens, meaning that you can look at distant objects in dim light. However, you should also consider whether or not you are willing to carry large, high-powered binoculars when selecting a pair. Many compact powerful models are available that can magnify distant objects while still being easy to carry around.

Eye Relief

A comfortable eye relief distance is very important for people who wear eyeglasses because their eyes may become strained otherwise. That is why eye relief is measured in millimeters, which indicates the distance from the object lens to where your eyes are when you look through the binoculars. The greater the distance, the more comfortable your eyes will be while using these binoculars.

Field of View

The field of view is the area that you can see when looking through binoculars. The area of view depends on how wide a lens has been used for magnification. The wider the lens diameter, the larger field of view you will have. Many compact models vary in magnification and objective lens diameter to provide a large field of view at a lower price than many high-powered models.


There aren’t many options to choose from. That’s because you can decide from just two:

Roof prism – This is a very popular type for a variety of outdoor activities. Probably a reason for that is that the models that have this prism are more compact, lighter, and more ergonomic. Thanks to modern technology, the roof prisms transmit light as good as the porro ones.

Porro prism – Traditionally, marine binos were made using this type of prism. As we mentioned, this prism enables a better transmission of light. Also, the size of the objective lenses is bigger. Porro prism can make the vision seem three-dimensional by giving much more depth.

Fog- and Waterproof

It’s imperative to look for binoculars that won’t be destroyed by water or fog. If fog appears, that may ruin the whole viewing experience and make the binoculars useless. Since you’ll spend most of your time on the sea, you’ll need these models to see the intended objects. Also, they work well in case of harsh weather conditions.

One thing to watch out for is ‘nitrogen-purged’ and such. That means that gas from inside will prevent moisture and corrosion from damaging the model. These items are known for lasting longer, too.

Unique Features

Since we’re talking about marine binoculars, these models have some special features. They didn’t say in vain that the devil is in the details. So, it’s a good idea to look for some models that have some of these extra features. They can sometimes come in very handy.

Some binoculars come with a compass. Most of them are built-in. What’s more, some models sport digital compasses and even illuminated ones. Binoculars for marine purposes are usually waterproof. And floating straps sound like a terrific accessory. Know that in some cases you can get some with the purchase. If not, you can buy them separately if you like.

FAQs (Frequently Asked Questions)

Q. Why should I buy marine binoculars instead of using regular binoculars?

Answer: One of the basic features, which separate marine binos from the rest, is waterproofing. Unlike other models, a waterproof one is suitable for adventures on the water. They will serve you in whatever weather condition you find yourself in. Fog protection is another strong asset of marine models. The lens stays crystal clear. If you get nitrogen-purged binoculars, then you’ll get all of that plus resistance to internal rust. Usually, binoculars for stadium events or birdwatching can’t float on water surfaces. Instead, marine ones have that ability. What’s more, some ordinary binos (like the ones for hunting, for example) can possess a laser rangefinder. This type of rangefinder will be unusable on the water, though. That’s why a reticule rangefinder is adequate for seeing the object’s distance. Another reason is that marine models most frequently have a compass, too. So, it’s safe to assume that marine binos are increasingly different. That’s because they’re made for special situations like yours. Thus, they have all the necessary features to be useful.

Q. Where should I keep my marine binoculars while I’m not using them?

Answer: It’s highly important for the storage place for your binos to be completely dry and safe from impacts or other damage. Usually, people use binocular cases which can be easily situated anywhere on a boat or ship. That way you’ll access them quickly and without any issues. A pro tip is to have the lens caps when you aren’t using the model. That way you protect it from scratches or dirt.

Q. What are some of the lens coatings found in the marine binoculars?

Answer: This is something marine models have in common with standard binoculars. Among the most quality lens coatings, one can find ED glass, BaK-4 prisms, fully multi-coated lenses, and such. ED glass is short for extra-low dispersion glass. It’s known to reduce the rainbow effect that can appear at the edge of the vision. Models with this type of coating usually have a slightly higher price. Many people state that the BaK-4 prism is much better than others like the BK-7. During internal reflections, plenty of light is saved due to this coating. Furthermore, with the fully multi-coated lenses, the users know that all of the internal air-to-glass surfaces are covered. That results in not losing a lot of light and better overall light transmission.

Q. What is the adequate eye relief in marine binoculars for people who wear glasses?

Answer: If you have to operate with binoculars with your spectacles on, it’s advised to consider an eye relief of minimum 15 millimeters. 17 millimeters would be an even more efficient solution. After all, it largely depends on the type of glasses as well as your face’s shape. Manufacturers usually make the modifiable eyecups that work by pushing and pulling. Also, some eye cups can be wither twisted up and down. However, each of these has its positive sides and drawbacks.

In the bottom line

If you have plans to go on a boat and want to take a pair of binoculars, you should be aware that the regular one that lies at your home simply won’t do. That’s because it will be easily damaged by the water. And it can even get lost in the vast water surface without you finding it. Being on the water warrants a special type of binoculars. And that is marine models.

So, it’s recommended to look for fog and waterproofing, the capability to float, as well as having extra features like a rangefinder, compass, and such. Also, be guided by your needs as well as your budget. And we’re sure that you’ll come across the pair that’s presently most suitable for you. We hope that we provided you with enough resources and options to consider before you make the final purchase. There’s nothing left for us to do except to wish you good luck and happy shopping!
