Since these binoculars will be used outdoors, possibly in rough terrain, it is important to look for a pair which is built to last and stand up to the odd fall or scrape. Binoculars are two mirror-symmetrical and identical telescopes mounted side-by-side and aligned to point accurately in the same direction, permitting two-eye viewing.
Waterproof and fog-proof binoculars are now available. Binoculars provide three dimensional images that have more depth. The first number is the amount of magnification or zoom the pair has.
The third- and fourth-generation night-vision binoculars show much clearer images at night, and are priced higher that the previous generation binoculars. 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. The first number gives the power of the magnification and the second number tells the diameter of the objective lens in millimeters which measures its light gathering strength.
They can be used while hiking, camping, boating and hunting. When I finally got my first pair of binoculars just a couple of weeks ago, it was like Christmas again. The feel of your new binoculars should be somewhat light but not too much.
There are also models with compasses built in, to keep you always on track when camping. Binoculars that have built in digital cameras are becoming increasingly popular among photographers, bird-hunters and those spies we mentioned earlier.
