Tower viewer

A tower viewer[citation needed] is a telescope or pair of binoculars permanently mounted on a stalk.

Tower viewers are typically metallic and most swivel horizontally and vertically (within given axes of rotation) to permit a range of view.

Tower viewers placed in public locations or used for fundraising purposes may be coin-operated or bill-acceptors; some others are free of charge.

Both firms offer wheelchair-accessible viewer bases that provide easy access to the sighting mechanisms in compliance with the Americans with Disabilities Act.

Tower viewer manufacturers located abroad include Hi-Spy Viewing Machines, Inc. (established in 1991) in Cobourg, Ontario, Canada.
