Binoculars are optical instruments used for viewing distant objects with greater clarity and detail. They consist of two parallel telescopes mounted side-by-side and aligned to allow the viewer to see through both simultaneously. When selecting binoculars, it is important to consider factors such as magnification, objective lens diameter, field of view, and exit pupil distance, as well as any additional features or accessories such as carrying cases, lens caps, and straps. CSP carries brands such as Nikon and Bushnell.
