Bushnell 138005 H2O Waterproof/Fogproof Compact Roof Prism Binocular

If you are on a budget, then this Bushnell binocular is something that you should keep your eyes on, as it is one of the better, budget binoculars. Compared to other binoculars in the same price range, this binocular excels in quality, magnification, and features. Its sight is clear because of the special optics and the magnification that you get can let you see anything that’s quite far away. If you’re on a budget, don’t go for a cheaper one but invest in this, as you’ll see the value when you use it for a while.

The waterproof feature of this product is quite good for this price range, as the product is entirely waterproof. This is made possible because it is O-ring sealed and is also nitrogen purged, so that there are no seams where water can get through and so that you can drop it inside a river or lake without facing the consequences. This binocular also comes with multi-coated optics and BaK-4 prisms to allow light to enter for darker environments and to allow a clearer viewing experience. We especially loved the multi-coating of this product because it is easy to get into a dark environment while hunting or exploring and with the help of the multi-coated optics, your binoculars will be able to gather all the light around you to transmit into your binoculars for use in the dark.

The quality of this product isn’t the best, but Bushnell tried its best to let you use the binoculars for as long as possible. This binocular comes with rubber armor, so that if you do happen to drop it, it won’t break since the rubber armor will absorb all the shock. The rubber armor will also absorb minor scratches as without it, scratches might create seams for water to enter your binoculars. However, the rubber armor won’t be able to protect your binoculars from fatal drops or hard scratches, so you still must be careful if you want to keep your binoculars lasting as long as possible.

The price of this product is one of the best things about this product. If you are on a budget then this binocular will be one of the better value purchases you can make as you’ll have to spend less money replacing your binoculars since this one will last a long time compared to other binoculars in this price range. However, if you are looking for better quality, then you will have to increase your budget as this binocular has great features, but lacks in certain aspects when it comes to the quality such as the optic lens and the focusing knob. Overall, this binocular is highly suggested for those on a budget that still want quality binoculars to view with on their wet trip.

Bushnell 138005 H2O Waterproof/Fogproof Compact Roof Prism Binocular, 8 x 25-mm, Black
  • Magnification x Objective: 8 x 25 millimeter
  • BaK 4 prisms for bright, clear, crisp viewing
  • Multi coated optics for excellent light transmission
  • 100 percent waterproof : O ring sealed and nitrogen purged
  • Non slip rubber armor absorbs shock while providing a firm grip

Polaris Optics RuggedEagle 8X32 Compact Birding Binoculars

If you have a bigger budget and you are looking for better quality, then you have come to the right place. This binocular is not only better in terms of quality, but in terms of value and features as well. This binocular is suitable for close to all activities and is durable enough to last through major drops without causing a dent on the product. If you aren’t on a budget, then we recommend that you read our review of this product, so that you can get a better value product for the long term.

The features of this binoculars are astounding. First, the optics are designed to give you the best clarity and contrasting view as possible, so that the colors stand out for you to enjoy without any vision loss. The optics are also multi-coated, allowing light to be transmitted to binoculars for a clearer view. Another feature about this binocular that we liked was how compact it was. The compact size of this binocular will allow you to keep it inside your pocket or inside a small compartment inside of your backpack without feeling it there at all. Lastly, the waterproof feature is present on this binocular, letting you dunk your binoculars inside water without fearing that water will get in because of the way it was designed. 

The quality of this binocular is definitely on the top compared to the rest of the products, primarily because of how expensive it is compared to the rest. However, the price is worth paying because the quality that you get is worth that much more value. The outer layer of the binoculars is coated with rubber armor to help absorb shocks from drops and the interior build is also laced with material that will help keep the binoculars from denting from high drops. The quality can also be seen through the optics and the focusing knobs, as they are both made from high quality materials and perform very well.

The only downside to this product is that it’s a lot more expensive compared to the rest of the products. However, if you would rather go for value than quantity, then it is recommended that you invest a bit more upfront rather than having to spend more money overtime to replace the cheap binoculars that broke with just a few uses. Overall, we highly recommend this binocular if you can afford it because it is arguable one of the best waterproof binoculars that you can get because of the variety of the features you receive as well as the quality that you get along with the waterproof feature.

AVANTEK Compact Ultra HD Binoculars

If you are looking for the average priced product that isn’t low quality or too high priced, then this product is the one for you. With high magnification and a wide FOV, you’ll be able to use these binoculars for whatever activity you will be involved in, whether it be whale watching, sports spectating, or whale watching.

One feature about this product that makes it decent is the multi-coated optics. Without it, you’ll only be able to see a blurry outline of your target, but with the multi-coated optics, you’ll be able to see your target clearly in the dark. This binocular also comes with BaK-4 prisms, so that your view will be a lot more brighter and crisp for you to enjoy and experience. This clearer display alongside the x10 magnification will allow you to see everything in closer detail, making your experience that much better. The wide FOV is another feature that we liked because it will allow you to have a wider range of view to find the target you are trying to find. With a tighter view, you’ll feel more restricted and it will also be harder for you to track down the object you are trying to find.

The quality of this binocular isn’t as good as the Polaris binoculars above, but it is good enough to last through drops, water dunks, minor scratches, and a few years of use if handled properly. Although you may not be able to see it, the internal components are of decent quality which will increase the length of time in which you will be able to use this product. Most low-quality products try to use high quality materials for the outside and low quality materials for the inside, explaining why they look good, but break quite easily unlike these binoculars which will last you a long time.

The price of this product isn’t too expensive, but it isn’t cheap either. This product is a good average product and if you want something above the low budget range, but don’t want to get anything too expensive, then this binocular is highly recommended as the price is right in the middle for those looking to increase their budget by a bit to get better quality. As this binocular is built to last awhile, the value that you will get out of this product will be a lot higher than a budget binocular, so we recommend that you keep that in mind as you are deciding as this product is recommended for its great features, quality, and price.

The last time I saw the moon with binoculars, it was not only nearer, but alive. It had mountains, craters, and shadows.’ Such is the rich experience binoculars give to the human race, to view distant things vividly without getting close enough!

These outdoor field glasses are designed such that two different telescopes are mounted parallelly and aligned to point in the same direction allowing the user to use both his eyes equally and to at-most efficiency, gathering more light, wider view range and hence better image quality.

These specially designed devices provide three-dimensional view unlike the monocular and hence foster life in inarticulate objects. The objects viewed through these field lenses are as clear and vivid as when they are seen through the naked eye. Now that you know a thing or two about the best marine binoculars, let us look into the use cases of these devices.

The binoculars have various applications apart from the typical use. These are as follows:

  • Land Surveys and Geographical data collection
  • Bird watching
  • Hunting
  • Range finding
  • Military purposes
  • Astronomical use

Since life these days is not restricted to land and advancements have been made underwater and over the heads, there certainly was a need to view and experience things there equally clearly as on the land, may it then be for leisure or for work. As they say, ‘Necessity is the need of invention’, so did the need for better view and safety underwater brought about manufacturing the best marine binoculars.

For using equipments in the vicinity of water, they must be designed with distinctive features so that they may not only withstand the pangs of watery environment but may also function well, emerging fruitful and excelling in their field of work.

For devices that are designed to work on the water surface and beneath it, there are certain specific features based on the working environment and fundamentals of optics that lay the foundation of binoculars that you must look for and understand while buying one to ensure that you have the best buy at affordable price.

Additionally, you must also lay down your needs clearly before jumping onto any conclusion of buying the best marine binocular. This would help you to filter out the best suited options of many available from various manufactures in the market, for because of much competition, there are numerous products often from the same manufacturer differing in specifications. Here are some features you need to look for while choosing a binocular,

Fog and Waterproofing

For anything related to water, it is important that it is waterproof so that the environment does not have any harmful effect on the product.

Similarly, for the best binoculars for boating, it is important that they remain waterproof, allowing them to excel under waters. Waterproofing of the device ensures that the device and all its parts remain resistant to harmful effects of water and that the water may not cause any hindrance in object viewing.

One thing that you must check thoroughly is that the binocular is waterproof in true sense. Most of the manufacturers misguide the customers by stating their products to be waterproof when most of them are just protected against water.

One should always look for binoculars that are completely O-ring sealed as well as nitrogen-purged. This means that the air inside the binocular body should be replaced by dry nitrogen gas. This prevents the internal optical instruments from fogging up and hence ensures unobstructed vision thereby keeping the device waterproof and fog proof.

The internal fogging up arises due to change in water temperature, the moisture free environment inside your optics because of dry nitrogen ensures that the device can be used in all waters and in all seasons.

It also has the secondary benefit of protecting the inner workings and making them resilient to any corrosion, which is especially important to those using binoculars on the sea.

Magnification

Often, under water the objects to be viewed are further than they are at land. This generally would mean that the marine binoculars should have high magnification power. But the truth remains exact opposite of this perception.

With binoculars of higher power, the image obtained of the object is least stable because with higher power, the disruptions due to ripples and movements get enlarged. Therefore, to obtain a stable image, it is advised to use marine binoculars with sufficiently high magnification power.

Therefore, most of the best marine binoculars have magnification power up to 7 times and yet give enough power so that the images are not to blurred and are of superior quality.

Rangefinders

Unlike the laser rangefinders in binoculars for hunting, the marine binoculars use recticle rangefinders often called as grid rangefinders. This is mainly because the ranges covered in water are much larger than the distance covered on land and therefore laser rangefinders do not work efficiently.

Compass

Most of the marine binoculars have a compass attached to their main body. The compass can be either analog or digital depending on the model of the binocular. These compasses attached, help in finding the right directions by pointing towards the bearing of the object.

Moreover, these compasses can range from being extremely useful to just an additional feature depending on the type of use the binocular is put to. If the compasses are to be used during the night time, look for marine binoculars which have compasses that have a light attached to them making visibility clear during the dark hours. However, compasses with lights would require a battery assistance.

Objective Lens Size

The objective lens is the lens that is present at the end of the binoculars. These lenses are responsible for controlling the amount of light entering the binocular and hence control the range of use.

Larger the size of the objective lens, more amount of light from the surrounding areas is directed into the binoculars. The binoculars with large objective lenses are typically useful for low light areas as they allow better vision. However, the size of the objective lens affects the overall size of the binoculars. The larger the size of the objective lens, the larger is the size of the binocular.

The objective lens used in a particular binocular is specified in the name of the binocular and is measured in millimeters. Most of the efficient binoculars have objective lenses of size varying in between 30mm and 50 mm.

Field of View

The width of the scene that is in the view when seen through a binocular is known as the field of view.

A wide field of view brings a wider perspective and makes locating objects an easier task as a larger area can be viewed at a time.

The negative point of wider field of view is that there is potential loss of details in the objects. Magnification power and field of view of a binocular are inversely proportional to each other. The larger the field of view, lesser is the magnification power of the binocular and hence lower is the detailing ability.

Size and Weight

The size and weight factor does not play a significant role and is therefore not of much importance for marine binoculars. The major reason being, these marine binoculars are majorly used onboard unlike to the field binoculars that are used for wildlife and birdwatching, due to which the size factor does not count in.

However, balance plays a key role. Unfortunately, the balance of a binocular cannot be compared without using the binocular. Generally, all well-built binoculars are also well balanced. A well-balanced binocular should cause minimum stress on arms, wrists and elbows when put near the face for viewing.

Eye Relief

Eye relief on a set of binoculars comes into play when glasses are being used by the user. Eye relief, basically is the distance behind the ocular lenses of the binoculars where the image of the object is in focus. Glasses come into the way of eyes getting closer to the ocular lenses as compared to normal eyes. Therefore, a longer eye relief is required that will focus the image of the object behind the ocular lenses. Normally, binoculars with eye relief of either 15mm or 16mm are recommended for unobstructed vision.

The negative of larger eye relief is that it compensates with the field of view. For those who wonder if wearing glasses is needed at all while using binoculars, here is a quick tip.

The binoculars compensate and make for both near and far sightedness and therefore the vision remains unaffected. Hence, there is no need of wearing glasses in such cases. Whereas, if the eye suffers from astigmatism, the user needs to wear glasses.

Floating Straps

If there is one thing that is often overlooked in marine binoculars is what when the binoculars fall off board? Though few of these binoculars are designed to float on the surface but many don’t. In such a case, the safest alternative is using a floating strap. These floating straps are attached to the binoculars and ensure that the binoculars float for long enough to be rescued.

Conclusion

The increased competition in the market has paved way for more and more companies to get into the manufacturing of the binoculars. Each differing model has different features most of which may seem alluring at the first go especially for the prices at which they are offered, but are not always fruitful. Therefore, it is always advised to list down the needs and areas of use beforehand and then hunt for the right binocular. It also advised to never compromise with the quality of the product no matter how tempting the buy may seem. Also, the final discretionary power vests in the buyer himself and therefore make the most use of it.
