ABSTRACT:
A pair of members (8) and (9) are joined by a pair of parallelograms (11) and (13) and when the members (8) and (9) are semi-circular in shape, they provide an apparatus and method whereby they may be positioned adjacent each other to form a circular member (C) and then stepwise moved toward and away from each other for use as a navigational aid. The members (8) and (9) may be in other shapes and may also be used to relocate various markings or designations on a map, chart and the like.
