Marine binoculars – Buying guide & Comparison


If you’ve ended up here searching for the best marine binoculars, you’ve come to the perfect place. After carefully analyzing dozens of reports, reliability surveys, and sales figures, we have concluded that the Steiner 280 Military/Marine is the model that you should bear in mind. The neat thing about this choice is that it has been outfitted with an autofocus feature, which means that you can visualize everything you need to see without the hassle of trying to focus the image time and again. The rugged design boasted by the Steiner choice is one of its greatest selling points, and that’s because it is very likely that it will hold well through the years. The 360 feet @ 1000 yards field of view enables owners to get a clear picture of what is happening in a wider area than what they would be able to see when using other models. Should this Steiner alternative no longer be available, we suggest giving a shot to another pair of good marine binoculars, the Steiner Marine Commander.

The Good
The Bad



If you have checked out loads of marine binoculars reviews and haven’t managed to come up with a model that best suits your expectations and needs, we’re here to assist you in this endeavor. To make sure that you spend your pennies wisely, we suggest going a thorough research on the topic. Check out our buyer’s guide and learn how you can make the difference between a pair of binoculars you need and one you might just as well do without.

Ruggedness matters quite a bit

While for some binoculars such as those destined for watching opera concerts, for instance, the ruggedness of the build might matter less, with marine binoculars it is a detail that you should always focus on. Such a product always needs to be free from fogging. As if you didn’t know already, boating is made in the water, so it goes without saying that the product has to be waterproof.


Magnification and image stabilization

Normally, we would suggest to assess your specific requirements and look at the type of marine exploration you perform and only then select the right magnification for your needs. In this case, however, we would suggest selecting a model that comes with a 7x or 8x magnification.

Why’s that? The fact is that things tend to move a lot on a boat. What this means for you is that, whether your hands are steady or not, you’re likely to have a hard time focusing the image or looking at a less shaky one. The lower the magnification power of a binocular, the steadier the image.

If you really can’t be satisfied with such a low magnification setting, it would be a good idea to consider a model that comes with image stabilization built into it. Just remember, the best binoculars for boating are those that fit your application and expectations as they should.


Objective lens diameter

Under regular circumstances, we address the magnification and the objective lens diameter in the same section of our articles. We’ve decided to make an exception in this case, though, and that’s because the lens size matters a lot when it comes to marine binoculars.

While larger lenses mean you’ll be able to look at a brighter image, you also need to consider the fact that such a pair might hang heavier around your neck. So, do portability and comfort matter more for you or would you rather look at a brighter image and ignore your body’s needs?


Field of view

While this factor might be less critical in the case of such binoculars, it is still worth giving some thought to. The wider the field of view, the bigger the picture you’ll be able to look at. We feel the need to reiterate that you should take a step back and decide whether looking at a bigger picture is more important to you than magnification and objective lens diameter, for instance, given that these two details can have a significant impact on your entire experience.



Some models take user experience beyond the limits you might have perceived in your mind. For example, there are various choices that come with a compass. Others are digital and believe it or not, some models come with their own camera built into them. If possible, you should look into getting a unit that comes with floating straps as no one can tell when an accident will happen and you might end up dropping the device in the water.
