Marine Binoculars Buying Guide

This section will cover some of the essential aspects of binoculars to consider before buying. Below, we provide the complete buying guide to ensure your satisfaction.

Fog and Waterproofing

Fog and waterproofness are the most significant features of top marine binoculars. Binoculars with non-waterproof interior lenses can fog up in damp marine environments due to changes in temperature and moisture.

Usually, the fog and waterproof binoculars are filled with nitrogen gas which doesn’t expand during temperature changes. So, if you want to protect your investment, look for a wholly sealed marine binocular.


The ability to see small details is essential for marine binoculars. The ideal marine binocular is compact, rugged, and easy to handle even when the boat is pitching.

Usually, most marine binoculars tend to have magnifications around 7x, which gives you enough power to zoom in and see things.

Again, stabilizing binoculars keep your view steady even as you move. Besides, they can compensate for magnifications up to 18x and avoid image shaking and blurring as you move.

Lens Size

The diameter in millimeters indicates the size of the primary lens in binoculars. For example, lens size 50 indicates that the lens has a diameter of 50 mm.

Usually, larger lenses gather more light so that they can provide better vision in dimmer environments. However, a 50 mm lens provides overall an excellent combination of l weight and light gathering.

Lens Coating

Around 5% of the light that enters or leaves a piece of glass reflects back. Besides, due to the number of air/glass surfaces on the binoculars, light may be reflected inside the lenses and can reduce the image brightness, sharpness, and contrast.

Therefore, mariner binocular lenses are coated with chemical layers that reduce reflection by 5% to 1%. If you are shopping for marine binoculars, make sure that both lenses have been completely multicoated.

Field of View

The width of the picture you see is defined by the field of view, which is measured in feet when viewed from 1000 yards away. Usually, the field of view of a pair of binoculars is measured in degrees.

Moreover, marine binoculars with a field of view of 385′ will display a 1000-yard-wide cone.
