They are especially useful for beginners as the right way up view makes it easy to navigate the skies. When you are hunting, having the best equipment to guide you is absolutely crucial.
Here are some factors you should consider when choosing hunting binoculars. There are many good choice in terms of value for the money, and have the added benefit of being ergonomically designed. The first number tells the magnification factor.
Generally, if the objective lens is 50 mm then it is considered to be a large binocular; if it is 42 mm, it is full size; if it is 32 mm, it is a mid size. As with the aperture of a camera lens, the size of objective lens determines the amount of light that can enter your binoculars. Phase correction is a coating on the lenses that increases the sharpness, contrast and color saturation.
A field-of-view of 390' indicates that the width of the sight picture is 390 feet at a distance of 1000 yards. If you are still in your twenties you can probably use all of that 7mm exit pupil above as your pupils will dilate to about that size in very dark conditions, however as you get older your pupil does not dilate more than about 4 to 5 mm so large exit pupils are wasted. The larger the second number after the "x", the more light that enters the binocular and the image will become brighter.
Nevertheless, the capabilities of binoculars appeal to both groups as they choose equipment that best fits their needs. So, get a good pair of binoculars and enjoy the birding.
