Tower viewerとは 意味・読み方・使い方

A tower viewer is a telescope or binoculars permanently mounted on a stalk. The device magnifies objects seen through its lenses, allowing users to see farther and more clearly than they could with the naked eye or with less powerful viewing devices. Tower viewers are typically metallic and most swivel horizontally and vertically (within given axes of rotation) to permit a range of view. The viewing machines are commonly placed in tourist destinations and scenic lookouts for the purpose of viewing attractions and events of interest; they are also used in residential, business, recreational and government locations for the purposes of surveillance and safety monitoring.
