The present invention is a tool for locating and marking center points on various objects configured with a geared carriage assembly having guide holes for insertion of posts and a counterpunch centered automatically when posts are inserted into an interior and/or exterior surface of an object such as a square, rectangular, polygon, circle or other circular shapes.
