Binoculars are an optical magnifying device making distant objects appear closer. Waterproof models are particularly useful at sea.
Binoculars achieve magnification through a combination of prisms, lenses and mirrors. Two numbers indicate their characteristics. The first gives the magnification, the second, the diameter of the objective lenses in millimeters. This last figure determines light-gathering capacity, hence, image brightness and clarity. A common example is 7x50. Some have additional features, such as a built-in bearing compass or infrared night-vision capability. Marine models are made waterproof by O-rings at key points and nitrogen purging.
The price of these optical instruments varies enormously depending on make and quality. Compass models are particularly useful when cruising for taking bearings on distant sea- and landmarks.
