An instrument having two coaxial centers, one inside the other. A telescope is attached to the inner center and mounted in such a manner that it may be rotated in vertical or horizontal arcs.

The scales are read visually by means of verniers. The instrument is usually leveled by means of four leveling screws. It is used for measuring horizontal, or horizontal and vertical angles.
