(Last Updated On: March 18, 2018)

 

Different types of binoculars are made for different activities. Some are made for bird watching, some are perfect for hunting, and some are for astronomy. Here we will discuss The Best Marine Binoculars available today and what are the features to look forward before buying a marine binocular.

First, Read an article given below,

It will help you to understand some of the terms related with binoculars such as magnification, an objective lens, eye relief, exit pupil etc.

 

Features to look for in a Marine Binocular

a) Magnification

On a boat in the open water experts always prefer a magnification of 7x, not more than that. Why? Because platform of the boat will not going to be stable and at bigger magnification, any small amount of movement will result in shaky images. 7x is the optimum magnification our hands can manage to keep binocular steady.

 

b) Objective lens size

Bigger lens size results in more light gathering power that will eventually result in a brighter image in dim light, however larger the lens heavier the binocular will get. So a 50mm is the most preferred objective lens size in top marine binoculars. They have a good balance between weight and quality of image.

 

c) Fog, Waterproof & Floatable

The most important feature to look for in marine binoculars. Suppose you are in a middle of the sea and accidentally you drop your binoculars in water, what will you do? The floatable feature will save it from drowning.

Sometimes, change in temperature can cause fogging inside the optics. So, to prevent binoculars from fogging and also to make it waterproof manufacturer put argon/nitrogen inside the tube and seal the O-ring.

 

d) Center focus

There are mainly two ways of focus mechanism available in binoculars, individual focus and center focus. In individual focus, the user focuses each eyepiece separately whereas in center focus user focuses on the object with the help of center knob a more versatile, traditional and easy way and also enable the viewing of close range objects.

 

e) Compass

Many binoculars come with an inbuilt compass. They enable you to project the bearing of objects. Not essential but nice exotic feature to have in binoculars. Depends on the user whether they want this feature or not.
