Who Should Buy Marine Binoculars
Marine binoculars are an essential requirement for people who regularly sail and enjoy navigating the sea. No matter what kind of vessel they are on, be it a motorboat, a dinghy, a sail, a folding kayak, or anything else, a good pair of marine binoculars will always be in a navigator’s kit.
Binoculars will help you see important things that are otherwise hard to see with an unaided eye so that their journeys are always safe. Being able to view landmarks, buoys and other boats from far away can guide you through the waters.
With their advanced range-finding reticles and built-in compass help with estimating the distance from an object through its size and determining the direction. They can also spot ongoing thunderstorms or strong winds so you can avoid them.
A decent pair of marine binoculars will also give you a chance to get close to nature by watching wildlife such as swimming fishes, flying birds and even leaping dolphins. Another great thing about marine binoculars is that you will enjoy fishing great catches in no time.
Important Features to Consider
Marine binoculars are different from regular binoculars because they are equipped with a lot of advanced features to meet the needs of navigators. Here are a few features you should consider when choosing the right pair of binoculars for yourself.
The main reason for using binoculars is to magnify things. For example, a 7x magnification means the viewed object will look 7 times bigger with binoculars. There is a range of binoculars available out there in the market with different magnifying powers. However, the higher the magnification, the lower will be the brightness of the image and shorter will be your field of view.
Therefore, just stick to 7x or 8x power unless you have a very specific need for viewing very long-distance objects.
Size of the Objective Lens
This is the place from which incoming light enters and the wider the entrance, the brighter will be your images. Marine binoculars are typically made with 50 mm lenses which work well for most purposes. However, you can get away with less such as 42 mm provide the binoculars have a great optical quality.
Porro Prisms versus Roof Prisms
Prisms are responsible for correcting the image as light passes through them before exiting the back of the binoculars. They can be one of the two categories: Porro Prisms and Roof Prisms. Roof prisms (with straight tube configuration) are generally considered inferior to Porro prisms (binoculars with a dog-leg shape). This is because Porro prisms deliver greater light transmission that results in brighter images and higher depth perception.
BAK4 versus BK7 Prisms
Prisms come in two glass types: BAK4 and BK7. BAK4 prisms are better than BK7 because they are rounder, have light transmission properties and are much more efficient. This doesn’t mean that BK7 prisms are of poor quality but they cannot match the capabilities of BAK4.
Lens coatings improve the performance of the lens by decreasing reflections and enhancing contrast. Binoculars with good lens coating will result in greater user satisfaction because of sharp images. Lens coatings come in four different qualities:
- Coated – one or more surfaces are coated
- Fully coated – All air-to-glass surfaces are coated except for plastic surfaces
- Multicoated – One or more surfaces are coated
- Fully Multicoated – All air-to-glass surfaces are coated
Coated lenses are the lowest quality as they cannot stop reflections substantially. fully coated lenses are better and quite economical. Multicoated or fully multicoated lenses are the best choices. Fully multicoated lenses deliver the highest light transmission resulting in bright and crystal clear images. Therefore, they are the priciest.
This is very important for people who wear eyeglasses or contacts. Eye relief refers to the distance at which you can hold the binoculars from your eyes while maintaining a broader field of vision. It’s always recommended to go for a product that offers at least 16 mm of eye relief so you can easily use it with your glasses on.
A number of binoculars offer diopter adjustments to allow eyeglass-free viewing. However, if you want to keep your glasses on, be sure to choose binoculars with collapsing eyecups to give room to your eyeglasses. All you have to do is push those cups in or out to set the right distance. They come in two types: twist up cups or rubber cups.
Because marine binoculars are used in fluctuating temperature, humidity and pressure conditions, they can’t be filled with regular air. A change in pressure may fog up your lens and at higher temperatures and humidity levels, this can lead to internal corrosion. That’s why nitrogen-purging is necessary so that the unit never fogs up and the optics function perfectly.
Water Proofing and Build
When you’re carrying binoculars on a boat, there is a high chance of water sprays from the waves or bad weather that can make things wet on the sea-faring vessel. Moreover, ocean air has high moisture content. Therefore, your binoculars should be able to withstand these conditions by offering waterproof and fog proof lenses. The good ones are even able to float in water if dropped accidentally.
A non-slip, sturdy design is also a must for marine binoculars because of the rough conditions they are operated in.
Frequently Asked Questions
Is Higher Power Better?
This is not true because a higher magnification power means images are less bright and your field of view is narrower. Moreover, most users will not be able to keep a marine binocular steady which makes the image blurry or jumpy. Therefore, a 10x power or higher will make you see too much jumpiness.
What’s the difference between multi-coated and fully multi-coated lens?
In multi-coated binoculars, one or more of the air-to-glass surfaces are coated, whereas, in fully multi-coated ones, all of the air-to-glass surfaces are coated. A binocular can consist of a dozen or more air-to-glass surfaces and each surface contributes to light loss as a result of reflection. Therefore, these surfaces are coated several times to give the best possible light transmission. The best quality binoculars are multicoated on all surfaces allowing the highest level of light transmission and nearly perfect images.
How should I clean my Binoculars?
Most manufacturers supply a cleaning tool or cleaning instructions for you to use when you need to clean your pair. It’s extremely important to use a cloth that’s specifically made for this purpose. It must also be clean and free of any debris as that may damage the expensive optics.
You can also get a lens paper and specialized lens cleaning fluid for this purpose. Just wet the paper with the fluid and gently wipe off the lens in circular motions. After that, take dry lens paper to clean off any remaining fluid from the lens.
Trying to clean lenses using your sleeves or shirt or a regular towel is a bad idea!
How does the exit pupil diameter make a difference?
Exit pupil diameter is the size of the shaft of light exiting the binocular eyepiece and meeting your eyes. It’s a factor of both the objective lens size and the magnification power of your binoculars. It is especially important when using the binoculars in low light conditions as the wider the shaft of light the brighter the image as more light will make to our retina.
Therefore, binoculars with larger exit pupil diameters will help you better pick up objects and observe every detail when it’s darker outside. So if you’re going to use your binoculars in dark conditions, choose one that has a larger objective lens size and lower magnification power.
Do I need a tripod?
Tripods make your view more steady and enjoyable even with low power binoculars. But if you’re going for long-distance viewing using high power binoculars (10x or higher), tripods will become pretty much necessity otherwise steady view will be difficult to achieve.
