These binoculars will get you closer. Actually, ten times closer, and you can only get them from West Marine!
From daytime sightseeing to nighttime stargazing, this new version of the Shoreline 10 x 50 Waterproof Binoculars from West Marine might just be your best option. Not only does their compact size and light weight (24 ounces) make them easy to grab and go, their included padded carrying case can be stashed in your backpack, duffel bag, dry bag, glove compartment and lots of other places. Plus, they're waterproof so a rainy day won't keep you from spotting that bull moose before he spots you. Their larger objective lenses are perfect for amateur astronomers since they are able to transmit more light through the binoculars and help you see better in the dark. You'll enjoy nature viewing in large, open areas and getting up close to the action at sporting events.
Just what does the 10 x 50 mean with these binoculars? The 10 identifies the power of the lens. Objects will appear ten times closer than they do with the naked eye. The 50 stands for the diameter of the objective lenses (the ones furthest from your eyes) in millimeters. The larger the objective lens, the more light can enter the binoculars. The more light they can gather, the brighter objects will appear—particularly important in low light conditions like cloudy days or when fog or rain are part of the equation.
Field of View
This specification is expressed with 1,000 yards as a standard for reference. These Shoreline binoculars have a field of view of 289 feet at 1,000 yards. That means you can see a 289-foot wide object at a distance of 1,000 yards.
Are these binoculars hard to focus? Not at all. A diopter (that ridged collar on the right side eyepiece) adjusts for the difference between your eyes (if there is any). Once you set that, simply turning the center focus knob will adjust the focus for both eyes simultaneously. This set-up makes it easy to view something quickly since you only have to turn the center focus knob when you point them at objects of varying distances.
This pair of binoculars has BaK-4 prisms that use a dense, fine barium crown glass which eliminates internal light scattering and produces sharper images. Without prisms, objects would appear upside down due to the refraction properties of convex lenses.
These binoculars feature multiple layers of optical lens coating to give you high light transmission (the amount of light that reaches your eyes), plus high image sharpness and high color fidelity.
Built to the IPX7 Waterproof Standard, these binoculars will survive immersion in water for 30 minutes at a depth of 1 meter. However, exceeding that time isn't recommended. So storing them somewhere cool and dry is a good idea. They're also nitrogen-filled so they won't fog up as the temperature changes.
The twist-up eyecups provide up to 18mm of eye relief so you can adjust them to fit the shape of your face. If you wear eyeglasses just keep them retracted since you have already created the necessary distance between the ocular lenses and your eyes which allows you to see the full field of view. You can even put your eyeglasses directly against the eyecups since their soft rubber prevents scratching.
Your binoculars are covered with rhino tough rubber armor. Not only does this protect them from shock and damage, it's also soft and comfortable in your hands.
