Widely used for stargazing, bird watching, hunting, and fishing, binoculars are of great use to sport and nature lovers. However I know that one mans opinion is often not enough, and people will continue looking for more and more information before they finally decide to buy.
The first thing to know about a compact binocular is that it is two small telescopes mechanically linked together. You'll need to choose the objective diameter for your binoculars. When hiking or orienteering, binoculars will be very useful, but it is important to note that optics are very fragile, and so plastic lenses over glass ones, and a rugged case are probably going to be more important than high power, or the ability to use them at night.
As with the aperture of a camera lens, the size of objective lens determines the amount of light that can enter your binoculars. Waterproof construction eliminates potential damage due to wet conditions. By selecting binoculars that have a rugged construction, you are less likely to damage them through bumps or drops.
But you d better make sure that they have the proper range, power and clarity. Do not waste your hard earned cash on a pair of cheap ones.
