The choice is really huge that you have to be selective to get the right pair.
Indeed, it is not enough to put in your basket the first pair of marine binoculars you see.
Caution is really essential before clicking on order.

No one would want to invest in a pair of binoculars only to complain about some detail and regret their purchase.
To prevent this from happening to you, we’ll give you some tips for selecting the best binoculars for marine activities.

Before we get into the criteria for selecting binoculars for boating, here are a few smart tips to consider.
The first thing to do if you come across a product is to check out the reviews on the internet.
Reading user reviews of the item is great because it allows you to filter out the positive and negative reviews.

Obviously, the second criterion before you buy marine binoculars is your budget.
So you have to know how to find a model that suits both your preference and your budget.
As for the price, you have a range of 100 to over 1000 euros.

After the price, you should also collect opinions about the brand that made the pair of binoculars.
What about its reputation?
But one of the most important elements is in the product description.
If you are not a person who has a good knowledge of optics, you will have a hard time.
But to avoid getting lost in all the technical details, don’t hesitate to follow this guide to buying the best binoculars.

First, here are three pairs of marine binoculars as an overview of the best models on the market today.
Below, we’ll show you some products with all the information you need to know.

How to choose your marine binoculars?

The destination has a lot to do with the choice of binoculars.
From opera glasses to hunting binoculars, the environment dictates the details to consider before buying a pair.
Since marine binoculars are used on a boat, for boating, they require quite a few essential qualities.
That’s why we’re taking the time to explain all the buying criteria before presenting you with the best marine binoculars.
So here are the 9 features to consider when buying a pair of marine binoculars, it’s up to you to note what you need most.

The Magnification

For the most part, binoculars for water activities are 7×50.
The 50 represents the diameter of the lens, and the 7 is the magnification value.
The higher the magnification, the better you can see the lenses, and the better your binoculars catch light.
This is quite true, but marine binoculars are a bit of an exception.
With the wrong magnification for the environment, you risk getting blurry, inaccurate images.

Remember that a boat is often in motion, and a high magnification needs stability to capture the image well.
So for your activities at sea, there is no need to take a high magnification factor.
We recommend that you choose a pair of marine binoculars with a magnification between 7 and 10.

A value of 7 is ideal for boats under 50 feet.
For a boat over 50 feet, with some stability, you can still get a pair with a magnification value of 10.


After magnification, the waterproofing of marine binoculars is never to be taken lightly.
This is really one of the most important details if you want to buy this equipment.
On a boat, the environment is not always favorable.
You’re exposed to the humidity of the nautical environment all the time, not to mention the weather conditions.
You need to find a pair of binoculars that can withstand the cold, humidity, sea spray, rain, snow, etc.
All of which can make your views less clear.

If you want to have weatherproof binoculars in your hands, you need to choose a pair with a good degree of water resistance.
These binoculars are designed to withstand water and temperature changes.

Waterproof marine binoculars are often equipped with hydrophobic coated lenses and O-rings to seal the housing.
Most models are even filled with inert gases such as nitrogen, argon and nitrogen to keep outside air out.
This makes waterproof binoculars robust, resistant to dirt, corrosion, and even the effects of salt.

The field of view

By simple definition, the field of view of binoculars is the widest dimension that can be seen with the device.
And in a more technical explanation, the field of view is the width of the area covered by binoculars at a distance of 1000 m.
The unit of measurement of the field of view can be in degrees or in meters (1° = 14.7 m).

The higher the value, the wider the view.
For a pair of 7×50 binoculars, the field of view is between 110 and 130 m.
A rather low value, but the main thing at sea is to have comfortable binoculars, offering you a clear image.


Brightness is one of the most important criteria for determining the best marine binoculars.
Your ability to use your binoculars in a dark or dim environment depends on the brightness.
To get an idea of what the brightness level of binoculars is, it’s in relation to the diameter of the lens.
For the 7×50 model, for example, the diameter is 50 mm.
The larger this value is, the better your lens captures light.

For marine binoculars, it is recommended to choose lenses between 30 and 50 mm in diameter.
Models that allow you to see sharper details at dusk, in the twilight or even at night, without tiring your eyes.
For nautical activities, it is especially recommended to buy monoculars with light intensifier.
Even if the magnification is low and prevents you from seeing at long distances, you can easily maneuver in the middle of the night.

The weight

Choosing the weight of a pair of binoculars is quite tricky because the heavier it is the better it is.
So you have to choose between heavy but powerful marine binoculars and light ones.
Although heavy binoculars are more exhausting, they are more advantageous.

A good pair of binoculars can weigh up to 1 kg or more.
This weight is often influenced by the type and amount of glass.
The larger the objective lens, the heavier your marine binoculars.
But if this heaviness takes up a lot of your time, you always have the choice of more compact binocular models.
But since it’s recommended that you choose a lower magnification for binoculars intended for marine recreation, there’s not much to worry about.

The setting

For these optical devices, we talk more about focusing.
First, there is the automatic adjustment system, i.e. the focusing of your binoculars is done without your intervention.
It’s very fast, because when you pick up your binoculars, the image automatically takes its sharp, clear form.
It’s especially effective in bad weather or in less unstable boats, because your binoculars automatically and quickly readjust its viewing distance.

The second type of focusing is manual, and can also have different options.
The first one consists in an independent focusing of the two telescopes.
You proceed to the adjustment of the telescope one after the other.
The second option is to be able to adjust the telescopes at the same time thanks to a central focus.
This type of model is accompanied by a large wheel placed between the two telescopes.
Marine binoculars with manual adjustment are very practical when wearing corrective glasses.
You don’t have to wear glasses anymore, because you only have to adjust the focus to your optical correction.

Finally, if you use your marine binoculars for medium distances, say 20 m to infinity, there are models that provide a clear view without requiring adjustment.
However, this type of binocular is not suitable for long or short distances.

The compass

Binoculars for water sports are even better if they are accompanied by a compass (analog or digital).
The compass is indeed very useful when you are on the open sea because it allows you to make the bearing of the object in view even from a distance.
With a reticle, you can calculate the distance and size of the object.
Most compasses have a reddish, battery-powered light.
Binoculars with a compass are highly recommended for recreational boating.


Without the prisms, the landscape you see through your binoculars would be upside down.
But this system has a lot to do with the weight of your binoculars.
But what we can remember is that there are two types of prisms, including the Porro prism and the roof prism.

The most often used is the Porro system for technical and practical reasons.
The Porro prism is indeed less complicated in the realization.
Also, for the user, the adjustment is more convenient.
However, the Porro prism binoculars are very heavy.
This is because the body contains two prisms on the right and left.
Despite this lack of lightness, this model is highly recommended for boating because of its stability.

As for the marine binoculars with roof prism, the body contains only two prisms on the left.
The manufacturing process is more delicate, which explains its cost on the market.
However, roof prism binoculars are more compact and lighter.
If you can’t handle heavy binoculars, consider this model.

The coatings

Even if you’re not a pro with optical equipment, you know how much reflection can interfere with seeing through glass.
On a sunny day, the sun’s rays can reflect off the glass lenses of your marine binoculars, preventing you from seeing your targets clearly.
The best marine binoculars for avoiding these effects are those with special coatings on the glass surface.
These coatings are designed to reduce glare or light loss.
Lenses aren’t the only part of a pair of binoculars that need good coatings.
For a good grip, the best binoculars are made with rubber coatings.
This prevents your binoculars from slipping out of your hand easily.
Some models even have buoyancy, in case your binoculars fall into the water.
