ABSTRACT:
Apparatus for mapping the outline of a surface area, such as a golf green, including a board having depending legs for placement on the green and a centrally mounted pivot peg extending upwardly from the top of the board. A sheet of paper is attached to the top of the board and typically surrounds the pivot peg. A dual segment measuring element includes an inner, rigid, proportional measuring segment and an outer, flexible, full-scale measuring segment. The inner measuring segment has a pivot hole for engagement around the pivot peg. The inner and outer measuring segments both have their respective zero-points of their scales coincident with the pivot hole. Full-scale measurements are transferred to the paper at corresponding points along the inner, proportional measuring segment.
