Binoculars are two identical telescopes placed side-by-side that are designed to point accurately in the same direction. Some scopes which are not well proofed for water or fog, are not as rugged.
The first thing to know about a compact binocular is that it is two small telescopes mechanically linked together. Magnification specifications of 8x42 or 10x42 are perfect for a variety of outdoor optics requirements. Telescopes provide an expanded view.
There are giant binoculars available with higher magnifications and apertures which are designed for astronomy use but you will certainly need a sturdy tripod or mount to use them. If you are using binoculars with a large, heavy objective lens it is helpful, if not necessary, to stabilize them by either resting them on something or mounting them on a tripod. When choosing hunting binoculars, look for phase corrected lenses.
The range of you binocular depends on three things, its gain, resolution and magnification. You want to become adept at identifying a bird correctly. The distance you will be from the object you view will determine the magnification power required in a pair of binoculars.
If you are going on a long trip, binoculars will be excellent entertainment for kids. All around the world people of all ages enjoy bird watching.
