Product Information

Essentially, the Hooway marine binoculars do the exact same thing as the aforementioned Bushnell binoculars. Like the Bushnell unit, these Hooway binoculars have a magnification power of 7x, an internal analog compass, and a range finding reticle to determine the distance of an object. The housing of the Celestron Oceana unit is made from durable rubber-coated material, which is completely waterproof and anti-slip. The inside of the housing is nitrogen-purged, which reduces fogging and increases the useful life of the binoculars. With the lightweight construction of the CL Companion binoculars and the impeccable build quality, you can be sure your investment will withstand the test of time, which is what you would expect as these are far from cheap. But I say you get what you pay for and the optical quality of these binoculars is possibly the best on the market. Binoculars with a 50mm objective lens are good for long range activities because they allow more light to enter the binoculars, which results in a brighter and clearer image. Whether you are out on the trail or inside a crowded stadium, you want a binocular that is comfortable to hold and use over long periods, without fear of bumps or drops. UpClose G2 features a lightweight and durable armor-protected chassis. Its tough, rigid frame is coated with rubber to stand up to hard use in the field. The UpClose G2 is also water resistant and can repeatedly stand up to unexpected conditions.

That first number that generally follows the model name of a pair of binoculars refers to the magnification. For example, an 8x42 pair of bins provide eight times magnification, which makes things look eight times larger. A 10x42 pair offers 10 times magnification, and so on.

Uses

A pair of 20×50 binoculars will magnify 20 times and employ objective lenses of 50mm diameter. These binoculars will provide an exit pupil of 2.5mm (objective lens divided by magnification). An exit pupil of this size provides plenty of daylight power with decent cloudy or late-afternoon visibility. You might want to add a tripod for stability, however. The comparison between weight is certainly the most noticeable difference here. Binoculars which increase in size will naturally require more glass for the lenses. Whilst this does not look like a big difference, it can certainly impact how accessible these binoculars are. This is especially true for long-term use of the binoculars. If you are looking for binoculars which are easier to carry around, then the 10x42 option is the best choice. The shape of the Hooway marine binoculars is wide and compact, which some people prefer to the traditional long-lens binocular style. Additionally, it stores well in compact areas due to its reduced length. These binoculars feature a handy range decoding system on the objective lens housing, which helps users focus the binoculars and determine the range of an object. This means that for your hobby or subject, it's worth thinking about what the best combination of magnification of objective lens size will work for you. Where these Opticrons fall slightly short is in what’s included, or rather not included, in the box. All you get is a basic pouch and a simple, non-padded strap, whereas the Celestrons include a stretchy neoprene strap, a pouch with extra compartments and a harness.

For the money and quality, most non-profits or struggling graduate students with an observational element to their project go with Eagle Optics, the company I feel has set the bar. The other common player we see at this table is Nikon, specifically their "Monarch" model. Relative Brightness is the exit pupil squared. The relative brightness has no relation to how bright a pair of binoculars will be. The quality of the optics has more to do with the brightness of the binoculars than exit pupil size. Bushnell has a long history of producing binoculars for the U.S. market. Over the years, this company has been a primary supplier of binoculars to the U.S. Navy, including during the second world war. As a result, they have plenty of practical experience designing marine binoculars. There are a wide range of factors to consider when deciding on which binoculars are the best choice for you. Factors such as the build design and lens quality are certainly important points to consider. However, choosing the right magnification and objective lens size is essential. This will dictate how effective the binoculars are at a certain range. Both the magnification and the objective lens size will impact how effectively you can use the binoculars.Another option, although much more pricy, would be the Zeiss Terra ED 10×42 which are also 100% waterproof and fog proof. Slightly larger design than the Avalon PRO HD. They produce beautiful images and excellent brightness. Details below:

According to your requirements we would NOT go with compact binoculars. They simply don’t have a wide enough field of view to spot planes or birds. Also, due to their small objectives, they don’t take in enough light so won’t be useful for watching at low light or at night. Full size binoculars will do a better job at all these but since you are holding them upwards these will be too heavy to use without a tripod. Also note that high magnification, such as 16x, will be good for seeing high flying aircrafts but too hard to stabilise while looking at any other subjects (airshows, birds, general use etc.). So if you want one pair of binoculars to do all then we would say your best bet would be mid power, mid sized binoculars. 10×42 in specific. We can recommend the Avalon 10×42 PRO HD which are of excellent quality and waterproof. They will sustain rain and you can even throw them into water. Details below: You are very correct. Zoom binoculars tend to have an inferior image quality than fixed magnification binoculars which is why most people stay away from them. If you are after compact binoculars then the Nikon Aculon 8-24×25 have a nice image in all zoom settings. Details below: Do not forget your binoculars at home. This is poor form every time. Are there any other things that you think are important to consider when choosing a product that we didn't cover? x 50 = bright, but not as much as 7 x 50. Decent level of magnification and can be hand held my many people.Keep in mind that the more an image is magnified, the harder it will be to keep that image steady. Many users find a magnification of 8 or 10 to be the highest that they can keep steady with their hands before a tripod or another type of platform is needed. A pair of binoculars with 20 times magnification would likely benefit from a tripod. Objective Lens Diameter If you are going on longer walks and size or weight are an issue you should instead opt for compact binoculars. 10×25 binoculars to be exact. These will have the same magnification (10x) but smaller lenses. They are significantly smaller and lighter and will be very easy to take along. On the downside they will not have as wide field of view as the larger models. For hiking we can recommend the Bushnell H2O 10×25 binoculars. They are compact, with a nice image and also 100% waterproof and fog-proof. Details of these binoculars below: My only complaint is that the focus adjust wheel is a little stiff and needs a fair bit of effort to shift. Oddly, the diopter adjustment wheel, which is handily located just behind it, is far easier to tweak. Binoculars all provide a wider view than telescopes or monoculars for example, because of their double eyepieces vs. only single for other scopes. But the more magnification you have, the narrower your view will be. The Celestron 25×70 for example are very high powered binoculars so have a narrow view. All of Canon’s current range of binos have the ‘IS’ suffix in their model name to denote the fact they’re image-stabilized binoculars. This battery-operated option enables you to get a wobble-free image by just pressing a button on the binoculars – and the stabilizing effect is both instant and jaw-dropping.

magnification allows for a good amount of detail to be seen when viewing objects in the night sky. Additionally, the 50mm objective lenses allow for a good amount of light to be gathered, which is important for seeing faint objects. Binoculars with a 20×50 configuration are good for astronomical use because they provide a wide field of view and a lot of light-gathering power. This makes them ideal for observing faint objects in the night sky, such as stars and galaxies. The sweet spot for birdwatching and nature-spotting binoculars is 8x. This gives you a reasonably broad field of view (usually around seven to eight degrees) and a good level of magnification, and you’ll be able to hold them easily without getting too much distracting shake.

Product Reviews

The 10x50 binoculars are the next step up in terms of quality and versatility. The wider lenses provide a brighter image in comparison and will perform better in low-light conditions. This does increase the overall size and weight of the binoculars, but certainly provides a boost to the quality. In addition to this, the 10x50 binoculars are perfect for activities such as stargazing. The wide lenses allow for bright and clear viewable images at all times - even at night. Therefore, it is clear that these binoculars are most suitable for long-range activities that require an in-depth focus.
