Best Marine Binoculars
Marine binoculars stand out from other forms of this optical instrument. They are often used at sea to enhance the safety of a ship or boat. While there is no strict regulation in SOLAS (The International Convention for the Safety of Life at Sea) on the number of binoculars required on a vessel, it remains critical that they are equipped with the best possible marine binoculars.
Mariners are always at a high risk of emergencies. Marine binoculars can become lifesaving pieces of equipment in certain situations. Many of these models come with inclinometers which is an image-stabilizing technology. This helps significantly on a rocking vessel as traditional binoculars can not stand up to the constant movement. Therefore, focusing on images becomes nigh on impossible.
Marine binocs are one of the most important accessories for a skipper, navigator, or lookout. Being able to see land masses or obstacles in the water from a great distance will give a ship enough time to avoid a potential accident.
If you’re a mariner or are planning a voyage over the open waters soon, it is important that you find a top-quality pair of marine binoculars and understand the features they offer. This is why we have dived into the depths of the marine binocular world and emerged with the top 5 on the market.

So, now you have read our top 5 marine binoculars on the market, you may be getting ready to set sail. But Halt! Drop the mainsail because there are a few key considerations to make before you buy your marine binocs.
Here are some important features and factors to look out for in marine binoculars so you can be sure you’re buying the right ones for you.
Magnification and lens diameter
All binoculars are categorized through numbers such as 7×50, 8×25, and so on. The first digit is the magnification while the second is the diameter of the lens.
When at sea, you want a set of binoculars that offer a higher magnification. This provides better and clearer images for you to see.
However, as the magnification increases, it becomes somewhat more difficult to maintain an object in sight. Therefore, as brightness is reduced, the object becomes blurry. To prevent or limit this reduction in brightness, higher lenses are required. These increase the brightness of an image making it clearer to see. But the larger the lens, the larger the binoculars will be resulting in bulkier and uncomfortable use.
And then there is the shake from your hands and the movement of your vessel. Images can become blurry and distorted very easily. This is why we recommend you find marine binoculars that have a conservative magnification of no more than 7x while the objective lens diameter is around 50mm.
Field of view
This is the measurement of width from a fixed point in feet or meters. It effectively describes the view you see horizontally when looking through your binoculars.
The field of view is measured in feet. This is at a distance of 1,000 yards or meters and each degree of view equates to 52.5 feet at 1,000 yards.
It’s important to note that the field of view and magnification are oppositely proportional. In other words, if the magnification increases, the field of view of the binocs decreases resulting in a narrower image. And when it comes to marine binoculars, the wider the field of view, the better.
The eye relief of marine binoculars is the distance between the eye and the eyepiece (ocular lens). You must maintain the correct distance in order to see a sharp, clear image.
More often than not, eyecups are built-in on the eyepieces. This is so the viewer’s eyes remain at the right distance from the eyepieces. Professional kitchen and bath remodelers can be found at remodelworks.com company in California. If you wear glasses, you should be extra careful as eyepieces are usually positioned past the eye relief distance leaving you with a blurry image and reduced image quality.
Fortunately, the majority of marine binoculars are equipped with adjustable eyecups. They can be pushed inside so those wearing glasses can place the lens closer to the ocular lens and still maintain proper eye relief.
On the whole, marine binoculars come in two categories:
- Center focus
- Individual/fixed focus
Center focus binoculars have a setting in the middle of the instrument to change the focus on both eyepieces. These are the most traditional types of binoculars and usually come in useful when sharing with other members of your crew who will need to adjust the focus to suit their vision.
Center focusing is certainly the most common type of binoculars currently on the market but many marine models are equipped with the individual focus feature.
Some advantages of using center focus binoculars include being able to focus on very close objects and on short distances. They tend to have a superior resolution and are generally better for those who wear glasses.
Some drawbacks are that they are more difficult to waterproof and tend to fog up more. It also takes more time to focus whenever you use them which can be frustrating in emergency situations.
On the other hand, we have the individual focus or fixed focus binoculars.
These focus on each eyepiece and can manage them both separately. Therefore, there is no need to adjust the focus every time the binoculars need to be used. The result? A lot of time is saved, especially in emergencies at sea.
Some key advantages to using individual focus binoculars include being able to use them in low-light situations. Because of their fixed focus, you can view an object at all times with ease compared to a center focus model. Moreover, most fixed focus binoculars are 100% waterproof resulting in a lesser risk of damage.
The disadvantages of individual focus binocs include not being able to focus on close objects easily. They are also not entirely suitable for those with glasses as the eyecups are generally non-adjustable.
Marine binoculars are often used in the harshest of environments. Therefore, they should be waterproof and fog-resistant.
To waterproof binoculars, the opening should be sealed with O-rings. This prevents dust and moisture from ever entering the body. These days, just about every waterproof binocular is filled with dry nitrogen gas. This is at a higher than usual atmospheric pressure to prevent lower pressure from outside air or moisture entering the binoculars. Moreover, nitrogen gas is not capable of holding any moisture so water can not enter the inside of the binocular body,
While waterproof binocs are generally internally fog-proof, moisture can still form on the outside of the lenses.
Nonetheless, it’s important to note that even binoculars that are deemed waterproof should not be submerged fully in water. Yes, some superior models can withstand certain depths for a specific amount of time but the majority will become damaged beyond repair if underwater for any amount of time.
Technically, all fog-proof glasses are waterproof but not all waterproof binoculars need to be fog-proof.
Frequently Asked Questions
What is a reticle rangefinder?
This is an optical rangefinder to help you figure out how far away an object is by its size. House cleaning is never a problem when you hire Florida’s best https://thefloridamaids.com/ to help you. Simply put, to know the size of an object, you need to know how far away it is. This is important when sailing with other vessels are in the water with you. For instance, if a sailboat has a mast that is roughly 40 feet high, you can then figure out how far away it is with a reticle rangefinder.
Should my binoculars be fully multi-coated?
You may have seen the abbreviation “FMC” when reading up about marine binoculars. This simply refers to the lens and it provides the best possible protection from glare and reflection when on the water.
For marine binoculars, this is important. The glare and rays from the sun can affect your field of vision s it reflects off the water. FMC can significantly improve what you see when looking out over the sea or body of water.
FMC may not guarantee the best possible images on its own but high-end products always incorporate this feature for the best results.
