We Spotted These Binoculars Deals Like a Hawk!

By , dealnews contributor

Oh, to have the eyes of a hawk, able to spot a mouse a half-mile away. Of course, being more clever than hawks, ever-adapting human beings invented binoculars, which give us even better long-distance sight. Whether your passion is watching birds, hunting, boating, or even studying the stars, a good pair of binoculars can bring these objects of interest up close and personal.

And although the notion of specialized optical equipment may make you see "$$$," we're here to bring you the best deals and discounts on binoculars around. 
But if you're a novice outdoorsman looking for a deal on a pair of binoculars, you should first know what it is exactly you're buying. Thus, here are some basics.

First, The Numbers

The specifications for each pair of binoculars is represented by two numbers, such as 8x32mm (found on the Barska 8x32mm Waterproof Hunting Binoculars mentioned further below). "8x" is the magnification, and "32mm" indicates the size in millimeters of the large lenses opposite the eyepieces.

Magnification is, of course, the size of the image in the binoculars relative to what you would see with the naked eye. If with a naked eye that tree you see in the distance appears to be 10-feet tall, through 8x binoculars it would appear 80-feet tall.

The size of the large front lenses matter because they gather light and help determine how bright and sharp the image is that you see. In broad daylight, small front lenses such as 32mm work fine, but in dim light you may want to opt for larger lenses such as 42mm. 

Another important number that usually appears on binoculars is the field of view, which expresses the width of your field of view at a specific distance: i.e. 124 meters at 1,000 meters. This means the binoculars show a 124-meter-width view at a distance of 1,000 meters. FOV might also be expressed as a percentage, such as 50 degrees. If you're trying to track, say, a turkey through brush, you'll want a relatively wide field of view so you aren't required to constantly move your binoculars. But if you're watching a bird in a tree, using a smaller FOV offers greater precision. Do note that too wide a field of view can result in distortion at the edges of your binoculars. 

Top-End Specs, and Whether You Need Them

Many people are seduced by power in binoculars, thinking a pair of 20x50mm must be a better deal than a similarly priced 8x32mm. However, this is not necessarily the case: the higher the magnification, the smaller the field of view. Also, think practically: binoculars can become heavy in your hand very quickly; it's hard for the human arm to hold binoculars rock-steady, and a small field of view will accentuate every tremble. For most purposes, binoculars with 7x to 10x magnification and a front lens of 30mm to 42mm provide good image viewing at a reasonable price. 

When selecting binoculars you must also be aware of the size of the exit pupil — small circles of light centered in the lenses when the binoculars are held at arm's length. These holes represent the size of the image delivered to your eye. If these openings are larger than your pupils, you won't benefit from the additional size. In this case, a really large front lens won't give you a crisper image. 

You'll always pay more for zoom binoculars that can zoom from 7x to 20x magnification. However, all the moving parts tend to make them less reliable than fixed-lens types. Image stabilized binoculars will also cost more than their non-image stabilized counterparts because they automatically compensate for any hand trembling.

Binocular Basics

  • Focus Knob: This adjustment piece should move smoothly throughout its range without binding or running too freely. Once in place the focus knob should have enough resistance to remain in position even when the binoculars are jostled. 

  • Adjustable Eyepiece: Binoculars have one eyepiece that allows those who wear glasses to adjust the eyepiece and use the binoculars without their spectacles. This diopter adjustment is made by screwing said eyepiece in or out. This adjustment should occur smoothly, but not freely. Some higher-end binoculars have a lock that holds the eyepiece setting in place.
  • Ergonomics: Are the binoculars comfortable to hold? To test them out, try holding them to your eyes for several minutes — not just a couple of seconds. Do they afford a solid grip? Can you reach the focus knob without strain? Do they fit your hands well? 

  • Spreading Mechanism: The distance between peoples' eyes vary and therefore so does the distance of their pupils. So, a pair of binoculars must offer adjustments to suit wider or narrower brows. The hinge on which binoculars spread should be smooth enough that you can make subtle adjustments, yet stiff enough to hold the desired position. Again, some better models have a locking mechanism for this. 

  • Coatings: Different lens coatings can reduce glare and increase the amount of light gathered thereby improving your field of view.
