The Pro Mariner waterproof 8×30 are ideal waterproof binoculars and Pro Mariner’s range of waterproof binoculars are innovative and effective to use on board, having rub-coated lenses that incorporate BAK4 prisms that are conducive to retaining extra light while at the same time, reducing eye glare.

Another type of waterproof binoculars are the Magellan 7×50 Marine which is all weather, rugged binocular ideal for use in the roughest waters and extreme weather conditions. It also includes an illuminated compass as well as an internal Rangefinder. Bushnell sets the standards for waterproof binoculars with its H20 10×40 WP/PF Porro Prism, which is reasonably priced and is completely O-ring sealed as well as being nitrogen-purged for waterproofing and fog proofing, in any kind of weather conditions.

The first time buyer of binoculars may be totally confused by the mind boggling array of options available, such as magnification, size, light factors, waterproofing, anti-reflective lens coating, viewing angle, rubber armoring and integral compass. But, there are a few simple rules that should be followed when purchasing waterproof binoculars and these include magnification, size of the objective lens, centre focus, fixed focus or individual focus, spectacle wearers, and quality and lens coating.

For magnification, a 7x magnification is the maximum requirement for waterproof binoculars that can be safely handled at sea because of the motion of the boat. The next thing to decide is the size of the objective lens which is the wide lens at the far end from where light gets transmitted to the binocular and for marine use; this should be 50mm in diameter. The smaller the wide lens, the smaller is the size of the binocular. In addition, most binoculars have a viewing angle of seven degrees and are quite acceptable for marine use.

The waterproof binoculars that are completely waterproof will cost about two hundred US dollars and to check whether the binocular is indeed waterproof, there should be printed on the binocular, words that state that it is waterproof or nitrogen filled.

In shopping for your pair of big binoculars it is important to keep in mind how binoculars operate and specifically what are big binoculars.

Binocular Basics

There are many factors to consider when in the market for a set of binoculars. One of those factors includes the intended use for the binoculars. Some uses could include stargazing, bird watching, surveillance, hunting trips, etc.

Another factor to consider, when considering the purchase of a pair of binoculars, is the power of the binoculars. The specifications and strength of the binoculars are represented by two figures. These two figures are generally listed side-by-side and separated by the letter x. For example, if pair of binoculars is described by the numbers 7 x 50, the first number represents the magnification and the second number represents the diameter of the objective lenses.

The magnification of 7, in this example, means that the viewed object will appear to be seven times closer than if viewed without the binoculars. The number 50, diameter of the objective lenses, equates to the ability of the binoculars to gather light. The higher the second number, the greater is the light gathering capability of the lens and therefore the brighter the object being viewed. A higher second number is particularly helpful if the binoculars will be used for stargazing.

What Are Big Binoculars

Binoculars begin to be defined as big binoculars when the second number, of the listed specifications, reaches the number 50 and above. Therefore a 7 x 50 pair of binoculars could be defined as a pair of big binoculars.
Although incredibly powerful and useful for such things as stargazing there is one significant drawback to a pair of big binoculars. That drawback is their weight. The weight of binoculars that are 50 mm and above makes it difficult to maintain steadiness when holding the binoculars up to the eyes. Therefore, it is often necessary to purchase a binocular mount to hold the binoculars and provide for a good viewing experience.

Some of the most powerful binoculars you will probably ever use are found at observation points at tourist spots. However, these are usually mounted to a pole or wall usually due to their weight. As the size of the object lens increases, so does the weight making some of the more powerful binoculars unwieldy for handheld use.

There are some long range observation binoculars made to mount on a rail on your back deck or on a boat rail as well as guard towers, and if you have a home with a view the ocean of a large mountain range you may want to look into getting some powerful binoculars to better enjoy the view.

Others have lenses with sufficient light gathering capabilities that they can be used to enjoy your home’s view during the day and then to do some star-gazing after dark. The Celestron 25X100 a pair of powerful binoculars, enlarges images by 25 times and has exceptional light gathering rated at 100 for nighttime viewing. Its weight of nearly 10 pounds makes it hard to hold steady by hand but it does have a tripod mount attachment.

Bigger Not Always Better

At 1000 yards, this pair has a linear field of view of just 157 feet, which is great for viewing spotted images, but hot for a panoramic view. If your plan includes viewing images both far away and closer, you may to look into a pair of not quite so powerful binoculars.

To put powerful binoculars in perspective compare the average use type of 7X30, which means they have an enlargement factor of seven and light gathering capability rating of 30. Excellent for everyday use in normal lighting conditions is usually has an objective diameter of between 6,8mm and 7.2mm.

Now, look at the Nikon 20X120 which has an objective diameter of 120mm which means it can see under extremely low lighting conditions. It also offers a 267 linear foot field of view at 1000 yards which makes it ideal for landscape viewing or looking at the night sky. These powerful binoculars would have to be mounted due to their weight, but its mount swivels 360 degrees and has a linear transition of between 30 degrees and 70 degrees.

However, with so many different makes and models incorporating many different capabilities there is sure to be a pair of powerful binoculars to suit your everyday needs without spending more than you want to look at.

Many things go bump in the night and it is often difficult to see what those things are. This inability of our vision to see in the darkness is based on the biological fact that the human eye can only see a portion of the entire light spectrum.

A quick lesson on light reveals that light is comprised of waves of energy. The length of the light wave is in direct proportion to the energy of that wave. The longer the wave the less energy it has. Therefore the shorter the wave, the more energy that wave contains.

Additionally, colors can be defined as light waves. The color representing the most energy, shortest wave length, is violet. The energy level of colors decreases in the following order: indigo, blue, green, yellow, orange and red being the least energy wave, longest, of the color spectrum.

Added to the mix are even lower light waves of energy that are not visible to the human eye. Infrared is one such wave of energy and is even further divided in three levels. Those levels are near infrared, mid-infrared and thermal infrared.

Infrared binoculars take these facts surrounding the energy of the infrared light wave and combine the magnification of binoculars with infrared capability to help aid in night-time viewing. How this infrared technology works and what to look for in infrared binoculars would be helpful to discuss.

How Infrared Binoculars Work

Most infrared binoculars incorporate a special illuminator that emits a powerful bean of infrared light. This light is not visible to the human eye and yet provides a light source that allows for objects to be seen at night. The captured reflected image, caused by the infrared light, is focused back through the lens into a specially constructed electronic tube. The resulting process transforms a weak reflected image into a stronger one.

Eventually, through a conversion process that involves photons and electrons, a greenish image is seen through the infrared binoculars. This greenish image is a reflection of the image that is being seen.

Features

Different makes and models of infrared binoculars are equipped with different features. Depending upon the intended use of these binoculars equates to what features you would wish your infrared binoculars to include.

Probably the most important feature of binoculars is the magnification. The magnification you choose is contingent upon their use. A magnification of 5.0 will help the observer to see beyond 200 yards away from the view point. Magnification less than 5.0 will decrease the range of yardage that can be seen from your vantage point.

Other factors to consider when considering a pair of infrared binoculars includes the weight, its durability, ease of accessing the controls, battery life and a diopter. Handling a lighter weight set of binoculars and ease of use will allow for better experiences in utilizing the infrared binoculars.

Binoculars are generally used for bringing an object closer in order to observe its actions and behavior. Ornithologists or those who watch bird behavior can see a bird blink from 500 yards or other such actions they try to catch on camera for their project.
