ABSTRACT:
In a device for use as a remote reflector in an electronic distance measuring instrument, a prism is mounted in the center of a two sided target, with both the prism and target being rotatable 360.degree., as a unit, about an elevational axis to provide bi-directional plunging. A yoke assembly allows this 360.degree. rotation. A second rotational joint on the yoke provides azimuth orientation of the prism and target assembly. Elevational alignment indicators, on the rotatable connection between the yoke and target allow rough alignment, while collimator sights mounted on the target provide more precise alignment.
