Abstract: A combined sighting target and bracket adapted for receiving a reflector housing for use with electronic distance measuring instruments in surveying and other civil engineering applications. The unique structure permits adjustment of three parameters that render the present invention generally compatible for use in conjunction with virtually any kind of electronic distance measuring instrument. One such adjustment, namely, vertical displacement between a reflector housing and the sighting target, permits duplication of any offset distance that exists between a telescope and ranging optics of the remotely located measuring instrument. The other adjustment features include elevation and azimuth angle variations that permit orientation of the reflecting device to be virtually normal with respect to the incoming and reflected laser, infrared, or other such energy commonly used by such electronic distance measuring instruments.
