In addition to its psychological definition, the Gaydar is also the name of a small,
keychain-sized
electronic device produced by the
Toronto-based company
Gaydar Direct.
At about 2.5" x 1.5", it is about the size of a
car remote, and is designed to send out
radio signals to other similar devices. The device, obviously, is designed to be worn by
homosexuals, who wish to identify and meet others of the same
sexual orientation while preventing potentially
awkward situations before they occur. When the Gaydar comes within about 20 feet of another activitated device, it
vibrates quietly, letting its user know that another of the same orientation is nearby.
The device sells for about $70 each. More information is available here, which appears to be the
product's official
