Abstract
A device for measuring the angle of orientation with respect to a known frame of reference between a first object having a first axis and a second remote destination comprises a first arm member defining a first longitudinal axis and an object engaging surface substantially parallel to the first longitudinal axis for engaging a first object. A second arm member is connected in pivotal relation to the first arm member at a primary joint for pivotal movement about a first transverse pivot axis intersecting the first longitudinal axis and defining a second longitudinal axis intersecting the first longitudinal axis and the first transverse pivot axis. A laser is mounted on the second arm member for projecting a laser beam along a laser beam axis parallel to the second longitudinal axis. A first angle measurer is mounted on the second arm member to measure and indicate the angle of the second longitudinal axis with respect to a fixed reference frame other than the first longitudinal axis.
