Buying Guide – Finding the Right Marine Binoculars for You

Best Marine Binocular ReviewsMarine binoculars are important for safety and enjoyment on a boat because they help boaters to see small, far away objects.  Boat operators have the ultimate responsibility to “maintain a proper lookout” while boating.  After accident investigations, boat operators are often cited by law enforcement for failure to maintain a proper lookout.  Hazards such as scuba divers and kayaks can be particularly difficult to see.

Binoculars on boats are used for the following purposes.  Our buying guide discusses how each set of binoculars functions for these purposes.

Maintain a Proper Lookout

Any set of binoculars mentioned in this guide is helpful to maintain a proper lookout.  Periods of low-visibility are particularly challenging, and during these times fog-proof binoculars are an important choice.


The telltale signs of changing weather, wind direction, and current direction can be difficult to see while out on the open water.  Binoculars are a helpful tool to see changing leaves, the directions that birds fly, or distant sea spray off of whitecap waves.


A powerful set of binoculars can help boaters see the signs of fish feeding.  These signs include birds that are hunting fish, baitfish jumping out of the water, fish jumping, and even swarms of bugs.

Wildlife Viewing

Dolphins, whales, porpoises, alligators, beaver, and manatees are just a few of the marine wildlife that often visit boaters.  Sightings of these animals make any boating trip special, and a powerful set of marine binoculars will help you and your crew enjoy the show.

With these objectives in mind, the information in this buying guide will help you to pick the right set of binoculars for you.  If you are boating on wide-open water, you will want stronger magnification.  If you are boating on rough water and you like the option to share the image with your crew, the ATN BinoX-HD 4-16x Smart Day and Night Binocular is your best choice.
