What to Look for in Marine Binoculars

It is vital you know that there is a broad range of marine binoculars that are being manufactured daily, which means that the market is flooded with different types of binoculars. However, take your time and ensure that you are getting something that you are sure it will serve you. When searching for the pair of marine binoculars that fits your style, consider the following elements:


Most marine binoculars have too much magnification for use on rocking, pitching boats. The larger the magnification, the better your view will be. Magnification is an important feature in a binocular as it sets the quality of your view.

Greater magnification with more power is unrivaled when it comes to marine use. Choose those binoculars with a high magnification to provide the best sight.


Good marine binoculars should have an integrated compass, but it also depends on your needs and preference, this is a bonus. The compass will give you a basic idea of direction at a glance. However, it is subject to the magnetic deviation, which varies from location to location.

With this feature, you can pinpoint the bearing of a particular subject. Some compass systems are illuminated, and some are not.  If you find out that you need this particular feature, then make sure that you get a compass that lights during the nighttime hours.

Fog-proof and Waterproof

It is important that you get binocular that is waterproof and fog-proof, which you can use in the marine world in case you have any worries that your binoculars may go overboard and fall into the water.

Make sure that you get the marine binocular that contains an O-ring seal and are nitrogen purged. This feature will make sure that the inside of your marine binoculars will have protection from corrosion are from all types of water and moisture.

Field of View

The field of view is the angular width of your image at 1,000 yards. In simple terms, lower magnification often means a wider field of view. The better field of view lets you see more without adjusting your binoculars.

With a wide field of view, it will be easy to locate subjects when you are looking through your binoculars. It also makes it that much simpler to find small and fast moving ones at closer ranges.

Objective Lens Size

The binocular lens size determines the amount of light that enters into your binoculars. The larger the objective lens of the binocular, the more light your binoculars let in, which is of particular importance in low light conditions.

Larger lenses, however, would mean heavier and bigger binoculars. A decent marine binocular will be fully multi-coated for maximum image brightness. The objective lens size provides what many people believe to be the best trade-off of size versus light gathering ability.

Eye Relief

Eye relief is surely something to be considered if you are a wearer of eyeglasses. You can use your binoculars without wearing glasses and the binoculars focus will compensate if you are near-sighted or far-sighted.

Eye relief of binoculars

Eye relief is the maximum distance from the eyepiece at which you can see the binocular’s full field of view. The drawback to longer eye relief is that it can reduce the field of view.

Size & Weight

The marine binoculars size and weight depend on you. Weight and size is a significant factor when choosing binoculars. Because a good marine binocular must be built tough, and weight will usually exceed what you find in a standard field binocular.

It’ recommended to get a light weighted marine binocular. Lighter binoculars will allow extended usage without feeling like you have brick tied around your neck.
