What To Look For
Marine binoculars help sailors spot distant obstacles and scan the waters for animals or boats. Most sailing binoculars are 7x50; these are the two main numbers on each binocular. The first identifies the magnification power, which should be big enough to get the job done, but no bigger. William J. Cook, former optics chief for the U.S. Navy, recommends 7x for marine binoculars. The second number refers to the size of the front lenses. Look for large front lenses that let in lots of light, even at night. These also keep the field of view wide enough for comfortable viewing.
Common Pitfalls
Make sure you buy waterproof binoculars, even if you don't plan on using them in stormy weather. According to Cook, rapid temperature changes can cause binoculars to suck in moisture, even when it's not raining. Don't fall for "water resistant" binoculars; only "waterproof" models are specially designed to prevent moisture damage. Some people also like rubber coating on their marine binoculars, but remember that rubber coating alone does not waterproof them.
Where To Buy
Internet stores, such as Binoculars.com and EagleOptics, have the widest selection of binoculars at decent prices. Some have special categories for marine binoculars that help shoppers navigate to suitable models. For guaranteed quality, check the websites of Nikon, Canon and Olympus for well-built binoculars and proven customer service. If you're a first-time buyer, consider visiting a nautical supply store to discuss binocular styles with experienced staff. Best Buy and REI also sell binoculars--and browsing in stores gives you the opportunity to get a feel for binoculars before committing.
Cost
You don't need to empty your bank account to buy a decent marine binocular. Bargains are available in 2010 for as little as $50. Prices typically vary from $100 to $500--and the higher the price, the better quality the binoculars usually are, according to Cook. For a quality model that is durable enough to survive ocean spray and the occasional spill, expect to pay $150 to $250.
Comparison Shopping
Some binoculars have individual focus, meaning each eye has a separate focus mechanism. With others, users can adjust both eyes at the same time. Since sailors typically use binoculars to view targets that are not moving quickly, they have time to adjust each eye separately for optimal viewing. As Cook states, "For use at sea or in the harbor... individual focus models still rule the roost."
Accessories
If you want true marine binoculars, look for those with a compass feature, as Binoculars.org recommends. These binoculars have compass scales visible in the lower corner of one lens, which helps users orient themselves. Some binoculars also have similar features that help users measure distance and height.
