Abstract : This patent describes an optical plummet azimuth reference assembly having a rigid, horizontal support containing a centerline inscribed therein and a pair of upstanding elements mounted on the support located at each end of the centerline. Each upstanding element has a vertical reticle co-planar with the centerline and a horizontal reticle, the vertical and horizontal reticles forming a cross there between. By mounting the azimuth reference assembly directly on an optical plummet with the centerline of the azimuth reference assembly co-planar with the centerline reticle of the optical plummet, the azimuth reference line of an object aligned with the centerline reticle of the optical plummet can be accurately and quickly ascertained.
