When equipping your boat for a day of fishing or just cruising around the lake, you do not want to forget to add a good pair of marine binoculars to the list. Preferably, something, rubber coated so they do not slip out of your hands and waterproof in case they do.
A pair of 7 x 50 marine binoculars may be the recommended configuration for most as it offers sevenX optics along with great light gathering ability to make it easy to see the shore at dust or just after dark.
Think of binoculars as two telescopes attached to each other, only small to be held in your hands. Each one has mirrored optics, which enlarge an image and an aperture opening on the exit lens to allow light into the lens to brighten the image. With marine binoculars it is also important to think about the possibility of fogging due to some extreme conditions you may run into on the water.
Pressurized nitrogen is near the industry standard used in marine binoculars, and other types, to limit the fogging potential when weather conditions may be unfriendly to normal optical equipment. This could be helpful in the event you become lost in bad weather, as well.
Look For Extreme Quality
For example, the Steiner Commander V marine binoculars are wrapped in rubber armor to protect against shock and to make handling in wet weather easier and more secure. Its Nighthunter optics are claimed to deliver 96 percent of peak light transmission allowing clear images in near dark conditions. The Steiner 7X50 a field of view of just under 400 feet at 1,000 yards and weighs just 37 ounces without the built-in compass. With the compass it weighs about 40 ounces.
Selecting a good pair of marine binoculars for you, but you will want to look for ruggedness as they will undoubtedly be put through some tough use on a boat. Waterproof to at least 15 meters will also protect them for the times they may end up sloshing around on the floor.
Look for the aperture size as well, as it determines the brightness of your image in low light conditions. An aperture of 7.1mm is recommended for marine binoculars which will be used in the evening or early morning. Rubberized coating to protect from shock and to help avoid dropping them, as well as any functions be able to be manipulated while wearing gloves are other considerations.
