If you’re in the optical instruments business, you’ve definitely heard of Bushnell. This American company is well-known for its high-quality gadgets, and the Bushnell H2O doesn’t disappoint. It measures 7 x 6 x 3 inches and weighs 25 ounces, which aren’t the smallest numbers on the list but still very compact and lightweight overall.

From the name, you can tell that this pair of binoculars comes with waterproofing. It’s also fog proof and offers decent images thanks to the roof prism. With the non-slip rubberized body, you can be sure that the Bushnell H2O won’t slip out of your hands if they do get wet.

In case they do, though, there’s a rubber material that covers the gadget’s body to protect it against any shocks or bumps.

Moreover, the pair is infused with nitrogen in its O-ring seal to further enhance performance in the presence of fog, which would probably be abundant at dawn.

This Bushnell model comes with 10x magnification power and a 42mm objective length, which means that you get around 4.2 of exit pupil, and that’s why it best suits daylight activities.

What’s more, the Bushnell H2O binoculars come with several coating layers to provide you with the best light transmission as well as let enough light get through to your eyes – the 42mm objective lens does a very good job in this aspect.

If your center of focus needs adjustments, you can easily do so using the knob on the binoculars. Not to mention, the eyecups are sliding ones to provide relief and comfort. Finally, the Bushnell H2O comes with a lifetime warranty, which should put your mind at ease if you’re not sure about the quality of this pair of binoculars.

Pros
  • Incredible value for the price
  • Robust construction

This one is one of the most compact binoculars on the market, measuring 1 x 4.5 x 4.4 inches and weighing only 10 ounces (second lightest on the list), so it’s no trouble to take along on camping or hiking trips. 

The 8 x 25mm model is even called “Pocket” to refer to how portable it is. Those numbers mean that the Zeiss Terra ED can magnify images up to 8 times compared to the naked eye, and while the 25mm objective lens size is a little small, it’s a very viable choice if you’re going to use the set in daylight.

The ED in its name refers to the fact that it uses ED glass for the lenses, and that’s why it can provide a wide field of view without compromising optical precision. Not only that, but the lenses are also coated with Hydrophobic Zeiss MC coating, which helps keep the natural colors of the objects you’re viewing, no matter how close they may be; everything will retain all the details.

Moreover, the Zeiss Terra ED design makes it easy to grip and handle, with the focus wheel falling right below your index finger naturally.

Choosing Binoculars

choosing best binocular

As I’ve mentioned previously, the fact that many aspects that influence the performance of a pair of binoculars overlap and that some even have inverse relationships makes the process of choosing a solid pair very hard. That’s especially true if you consider all the jargon involved, which could deter people who aren’t well-versed with these gadgets.

For these reasons, I’ve prepared this comprehensive buying guide that includes all the information you may need and covers all the bugging questions you may have in mind.

Magnification Power and Size of the Objective Lens

The magnification power and objective lens size are two numbers that go hand-by-hand, but don’t necessarily correlate to one another. 

To illustrate, let’s take the Celestron 71346, for example. Its magnification power is 8 x 42mm, which means that the images you look at will appear 8 times bigger than they would to the naked eye, while the size of the objective lens measures 42 millimeters.

The first part is pretty straightforward, and through the first measurement, you’ll be able to gauge the number of details you’ll be getting.

However, bear in mind that with the magnification power, a bigger number isn’t always better. This is because, with higher levels of magnification, the binoculars are bound to move around a lot due to your own natural movements, which would make the images look shakier.

As a rule of thumb, 8x magnification power is good for general purposes like bird watching and so on.

On the other hand, the second number, which is the lens’s size, seems obvious but entails more details. The objective lens is the one that sits furthest from your eyes, and in the Celestron 71346’s case, it is 42 millimeters in size.

In terms of sizes and their relation to compactness, a 42mm objective lens is not the most compact, but it’s still good enough for throwing inside your backpack without taking too much space.

The real indicator behind the objective lens size is how much light it would allow into your eyes. The bigger it is, the more light it would allow to pass through, consequently enhancing your vision. 

That’s why you should opt for bigger objective lenses if you’re going to use them for low-light conditions. However, if you’re going to use them at dusk or in the morning, they might be too bright and compromise visibility.

Magnification Power, Field of View, and Exit Pupil

The field of view is another aspect that involves magnification power. It refers to how much area you’d be able to see when your binoculars magnify the image of the object you’re looking at. Generally, the average field of view on the market would range between 310 and 340 feet.

Usually, the higher your binoculars’ magnification power, the smaller their field of view would be. So, if you’re concerned with more visibility of the object, you can sacrifice the field of view for a higher magnification power. While if you’re bird watching or checking out landscapes, you should get the widest field of view at the expense of magnification power.

Finally, the exit pupil is basically the diameter of the objective lens divided by the magnification power. So, the Celestron 71346 would have a 5.25 exit pupil (42 / 8), a measurement of the light that reaches your eyes.

Generally, an 8 x 56mm would be the brightest you could get for practical purposes. It would give you an exit pupil of 7, and the average person’s ability to receive light is around 6 millimeters. So, that’s why you don’t see options with numbers higher than that.

Lenses

When you’re considering binoculars, you’ll be faced with two types: objective (the one furthest from your eyes) and ocular (the one closest to your eyes). 

Both of them are made of glass that’s specifically designed to magnify objects. Still, the difference in the speed of differently-colored light waves passing through them can cause a distortion that’s known as “chromatic aberrations.”

To deal with such distortions, manufacturers have to add coats to the lenses whose job is to unify the speed at which all light rays travel to process them simultaneously and correct the aberrations. Alternatively, extra-low dispersion (ED) can be used, which does the same job with no special coats.

However, binoculars with ED glass are usually more expensive, and it’s harder to find a compact pair of binoculars with ED glass.

Finally, it’s worth noting that some coated lenses have better performance than others, so make sure you know what you’re opting for before making the purchase.

Prisms

There are two types of prisms: Porro and roof. They work on fixing the images that would otherwise appear upside down and backward.

A Porro prism is the one that’s more commonly used, especially on older binoculars. It works by sending the length of the prism’s image, sending it to another prism for a 90-degree turn, and then sending it to the ocular lens for another 90-degree turn. And though the mechanism might sound outdated, Porro prisms still give high-quality images at very affordable prices.

On the other hand, roof prisms are located at the roof of your gadget and use advanced, roof-looking prisms. Though they’re a little pricier, the most significant advantage of roof prisms is that they’re ideal for compact binoculars. Bear in mind, however, that they also usually have smaller objective lenses and a smaller field of view.

Construction

On the topic of prisms, roof ones take the cake when it comes to durability, which is why they’re amazing choices for outdoor activities like camping, hiking, or hunting.

It wouldn’t make sense to look for the most durable pair of binoculars and pay extra money for a roof prism if you’re going to use it for bird watching from the patio, though, so make sure you match the specs and features to the purpose.

Another thing to be on the lookout for is whether your binoculars are gas-sealed or not. A gas-sealed pair comes with a main chamber filled with nitrogen or argon. Generally, they take out the oxygen and pump it with an inert gas to prevent any fog or vapor from distorting your vision by gathering it on the lens.

What’s more, you should opt for waterproof binoculars if you’re going to use them during winters or rain. Also, if you’re going marine life-watching, you can’t compromise on a water-resistant pair of binoculars. Getting ones with a reliable outer coat is also another way to make sure that water won’t invade them if you drop them and provide a good grip, even if they become wet.

Diopter

A diopter is typically found on the right eyepiece, which you can use to make adjustments if the center of focus goes out of alignment due to small bumps or hits that your binoculars are bound to take. The diopter enables you to align the left and right eye’s strength to have the same focus.

Eye Relief

Binoculars with eye relief would be a lot more convenient as they have retractable eyecups that provide more comfort for those who wear glasses or extend to provide extra shade. The best ones are those with multi-adjustable and durable eyecups.

If you wear eyeglasses, set the eyecups to the minimum position and make sure you don’t see any black rings encompassing the image. If you don’t find any, then the pair has enough eye relief for you.

Accessories

Generally speaking, you shouldn’t make a verdict depending on the accessories as they can be replaced or bought, but they just add more convenience to the experience and give you a greater overall value if they come with the set of binoculars.

The handiest ones would be a carrying case, a wiping cloth to keep the lenses clean, lens caps to protect the lenses during storage and periods in which you won’t use them, and a neck strap for more effortless mobility when you have the binoculars on you.

Binoculars According to Specific Uses

If you’re not sure how to match certain specs of your binoculars to the features we’ve discussed, here are the most popular uses and the types that suit them.

  • Traveling

If you’re going to travel around a lot with your set of binoculars, you should opt for mid-range magnification and field of view, which you can easily find on compact and lightweight models.

  • Watching Birds

This purpose requires a wide field of view and magnification power of around 7x. You can go for a higher number as long as it doesn’t compromise on the field of view.

  • Outdoor Activities

If you’re going to take your binoculars while you’re hiking, camping, or hunting, you should opt for models that combine a lot of portability and durability. Usually, a magnification power ranging between 8x and 10x would be good enough for outdoor activities’ general purposes.

You have to make sure you get a pair with a large objective lens diameter to take in more light and reliable coating to provide reliable performance in both low light and bright conditions.

  • Marine Life

For this purpose, you’ll need a wide field of view and vibration reduction. Needless to say, you have to get a pair with solid waterproofing.

  • Astronomy

This purpose is a little particular, and for it, you’ll need particularly large objective lenses and exit pupils. Also, make sure the pair comes with reliable aberration correction.

  • Sports

If you want to watch your favorite team play using binoculars, you should opt for more expansive fields of view and magnification power of around 7x to 10x. If you can land one that’s capable of zooming in and out, that would be a jackpot!

  • Museums or Theater

To get the best vision of a stage performance, you should opt for compact binoculars with magnification powers ranging between 4x and 10x. Make sure the pair is lightweight and has a focus distance below the 6.5-foot mark.
