Leveling plummet for measuring slope and drop angles, also usable as topographic level, characterized in that forming a single body with the upper part of two converging arms integral with a base, a limb with a sexagonal graduation is arranged whose axis is inclined 45º on the horizontality, taking advantage of the same length of circumference in its two working positions; this set has a drill hole in the center of the semicircle, located at the point where a line perpendicular to the support base intersects another line parallel to this base.
