In a method of determining the direction of a target by means of an optical square and passing on this direction to a magnifying sight for warfare tanks the exit window (4) of the optical square is provided with a vertical line of sight (8) and the entry window (1) with a sight aid (11). Marked areas (5, 10) in the exit window (4) have the effect that upon adjustment of the sight to the direction defined by the sight aid (11), the marked area positively will lie within the field of view of the magnifying sight.
