Abstract:
A scale, such as a tape measure, is provided with a plurality of slots corresponding to graduations on the scale. The slots are alternatingly located on opposed edges of the scale, and edges of each slot are collinear with edges of opposing slots. When measuring a distance to a line or a point, the line or point will appear in only one of the slots. The slots are tapered to a point at a specific graduation.
