ABSTRACT:
A geographical location pinpointer comprises a map having a set of spaced indicia located along its periphery, and a locator device including a linearly extending, radial arm and at least one curved arm both of which are movable with respect to the center of the map. Each point of interest on the map is uniquely identified by first and second indicia, and then located by positioning the radial arm and the curved arm at locations corresponding to such indicia so that the two arms intersect over the point of interest. Because the radial arm extends linearly from the center and the curved arm does not, the two arms intersect at only one point for each set of first and second indicia.
