1. An apparatus configured to assist a user in navigating to and identifying a point of interest at a known position in a reference frame, comprising:

  • a visual display configured to display image data;

    a laser mounted to a surveying pole in a downward-pointing orientation;

    a first imaging device configured to obtain first image data, the first imaging device having an optical axis extending in a first direction;

    a second imaging device configured to obtain second image data, the second imaging device having an optical axis extending in a second direction substantially perpendicular to the first direction, wherein;

    the first imaging device and the second imaging device are arranged such that when the apparatus is at a first position the point of interest is within a field of view of the first imaging device and outside a field of view of the second imaging device;

    when the apparatus is at a second position the point of interest is outside the field of view of the first imaging device and within the field of view of the second imaging device;

    a laser mark, generated by the laser, is within the field of view of the second imaging device; and

    the first imagining device and the second imaging device are mounted to the surveying pole; and

    one or more processors configured to;

    determine first image coordinates of the first image data associated with a location of the point of interest, and when the visual display is displaying the first image data, to superimpose a first navigational graphic on the visual display overlaid on the first image coordinates; and

    determine second image coordinates of the second image data associated with the location of the point of interest, and when the visual display is displaying the second image data, to superimpose a second navigational graphic on the visual display overlaid on the second image coordinates.
