The Vortex Viper HD 8x42 binoculars provide the sort of clear, crisp, high-contract image you'd expect from $2,000 binoculars, but at a fraction of that price. They have high-density, extra-low dispersion glass, fully multicoated lenses and dielectric-coated roof prisms to gather more light. They're also waterproof and argon-purged to prevent lens fog, with an eyeglass-friendly eye relief of 18mm. The Viper performs exceptionally well in low-light conditions, and Vortex's lifetime "Very Important Promise" guarantee is exceptional.
I would personally recommend the Bushnell 10x42 Legend M-Series Binocular, B&H # BU10X42MBRR, or the Vortex 10x42 Diamondback Binocular, B&H # VODB10X42, for your usage needs.  Both would have great optics and would be good for magnification for viewing boats from your beach house and for viewing wildlife.  The larger 42mm diameter also makes it good for capturing light, so it would have good performance in slightly lower light when trying to view deer in wilderness or forests. 

The actual field of view is the angle of your viewing window at the point after the binocular lenses. If you have a pair of 10X binoculars, and your actual field of view is 5 degrees, then your apparent field of view will be 50 degrees. You simply multiply the actual field of view measurement by the magnification of your binoculars in order to get the apparent field of view.

I believe that the joy of every parent is seeing their kids happy. When you are taking them to watch wildlife, birds, scenery or game, equipping them with a quality kid’s binocular enhances their experience. Kids can see every single aspect about their target object as compared to watching with naked eyes. With the Luwint, you are sure that they will have the best vision all the times. The features of this quality and affordable binocular include:

The coating on a lens has almost as much to do with clarity and brightness as the lenses themselves. A good coating can reduce the amount of scattered light down to a quarter of a percent per a surface. Scattered light is lost or misaligned information. You can have the best lens and coatings, but if all the elements aren't lined up and centered your image will come out distorted. With a minimum of 6 elements and some models having up to 20 elements, plus the two barrels, getting everything aligned can be very difficult. Fortunately, our brains are good at compensating for small misalignments. However, misalignments can add to eye strain.
To say that the 26050I Equinox Series L night vision binocular is one of the best digital night vision binoculars I have ever operated is understating it. This sophisticated binocular can be used both during the day and at night. For night time viewing, the binocular has one of the most powerful infrared illuminators I have ever seen on a binocular. In low lighting, I am able to view objects as far away as 250 yards
Roof-prisms designs create an instrument that is narrower and more compact than Porro prisms. There is also a difference in image brightness. Porro-prism binoculars will inherently produce a brighter image than Schmidt-Pechan roof-prism binoculars of the same magnification, objective size, and optical quality, because this roof-prism design employs silvered surfaces that reduce light transmission by 12% to 15%. Roof-prisms designs also require tighter tolerances for alignment of their optical elements (collimation). This adds to their expense since the design requires them to use fixed elements that need to be set at a high degree of collimation at the factory. Porro prisms binoculars occasionally need their prism sets to be re-aligned to bring them into collimation. The fixed alignment in roof-prism designs means the binoculars normally will not need re-collimation.[7]
Most kids love doing what their parents do. As a parent, you should encourage them especially if there are some educational values that they will learn.

This year we put more scopes and binoculars than ever (27 total) into the hands of more testers than ever, including myself; gun writer and F&S contributing editor Richard Mann; and University of Rochester optics professor Jim Zavislan and four of his hunting buddies and fellow optics nuts: Jeff Arndt, Joel Hoose, Marty Lasher, and Tim O’Connor. The result is our biggest, most exhaustive optics test to date.

The telescope represented a major triumph when it was originally introduced during the 17th Century. This one invention held the capacity to connect man with the stars. And yet if there was a drawback to the telescope, it was that the single lens did not allow for any depth. In order to see things in 3D, a telescope would've required two lenses, situated side-by-side. And this was how the earliest pair of binoculars were born.
Have fun exploring the outdoors with the Learning Resources Primary Science Binoculars. These binos are designed for younger explorers. They feature soft rubber eyepieces, a simple focus knob, hand grips, and a breakaway lanyard for safety. Reviewers like these for young children because they are very durable and the magnification is fairly low, which is easier on the eyes.
Clarity of images in any binoculars is determined by several factors. The first one is usually the aperture of the binocular. The Sniper Deluxe Night Vision Binocular has a large F1.4 aperture. It also has enhanced multi-coated lenses. These features allow the user to experience very clear images both at night and during the day. If you have a low budget or you are a beginner, this particular product will suit your needs. It is great for search and rescue, locating nocturnal critters and surveillance.
GPS ID stamp is also available when you are viewing and recording video. If you do not have this information, you can easily enter it manually.

The device weighs 780g or approximately 1.6 pounds. The package includes a carrying bag and belt as well as a cleaning cloth, USB cable, and AV cable. 4 AA batteries power the device. Users are advised to use alkaline batteries for optimal performance.
Field of view (fov) and magnification are related; for a given situation, fov increases with decreasing magnification and vice versa. This applies to monoculars, binoculars and telescopes. However, this relationship also depends on optical design and manufacture, which can cause some variation. The chart below has been compiled by the author to show the fov/magnification relationship based on best-in-class data, taken both from personal tests and from manufacturers' specifications. Contrary to some belief, it is a myth that binoculars offer a wider field of view than monoculars. For a given specification and manufacturer offering both monocular or binocular options of the same model, the field of view is exactly the same whether monocular or binocular.
The EL only has one downside, and it's a big one: price. Listing for $2,888 these bins cost as much as a used car and are more of an investment than a purchase. However, if you're a serious birder or wildlife watcher that wants the absolute best, or you're embarking on a once in a lifetime safari, these bins will undoubtedly elevate your experience.
(Close your right eye and sight an object with your left eye, focus the binocular by rotating the center focus wheel until the image is sharp and clear. Field of vision: 96m/1000m 20x. Open your right eye and close your left eye, rotate the right eyepiece until the object sighted is sharp and clear(Note the setting of the diopter scale for later use).
For people who wear eyeglasses, eye relief is an important specification. Eye relief is closely related to field of view, as it is the distance that you can hold the binoculars away from your is a good rule of thumb for people with eyeglasses. With sufficient eye relief, a person that wears glasses is able to enjoy the same field of view as everyone else.
Because binoculars usually allow focusing adjustments for both eyes, with a center knob controlling both sets of optics and one side of the unit featuring another ring for fine tuning (most people have slightly different vision quality in each eye), they can provide a sharp view indeed. But that also means more effort required to achieve this sharp view, and it means more potential for improperly focused optics that can cause frustration, eye strain, and that can hamper your distance vision instead of helping it.

Believe it or not, it might be a better idea to talk to a consultant or seller, ask for the opinion of a friend or acquaintance, and read some online reviews, than to trust the product description. Each individual’s eyesight is different. Some hunters wear glasses and others do not. Some folks are interested in fast-moving game that’s usually found in deep forests, whereas others like to hunt on planes.
“Took these binoculars to see Cavalia Odesseo from the nosebleed section and I must say they gave me an excellent view of the horses and acrobatics. I could easily see the violin soloist, the Spanish guitarist, and the enchanting vocalist behind the shrouds on the balconies. I will never watch a stage performance the same way again. I find that at a certain distance, I didn’t have to adjust the focus as often as I had expected. The focal sweet spot is pretty large. There is a mild chromatic aberration when viewing in daylight hours against the light, but this goes away when I fine tune the focus. For the price, these binoculars can’t be beat.”
