Miniature binoculars are great to carry in your coat pocket – and good for anything from a football match to field-sports or when traveling.
If you want a really compact unit, think about a monocular, which has just one telescope device (or cylinder) to view objects with one eye, rather like a telescope. The difference is in the optics and lenses inside the body: a telescope is a cylinder with lenses that magnify and focus, whilst a monocular also uses prisms to reduce the physical size of the device without sacrificing magnifying power. They’re typically sufficiently small and light enough to be hand-held, and can often in your pocket.
Specialist binoculars are also available: there are models available that offer binoculars for military and laboratory use.
