Abstract
A golf-leveler device, process for making a golf-leveler device, and a method of using a golf-leveling device comprising a 360-degree dome leveler housed within and at one end of a standard golf ball and having a base at the opposite end. Both the dome leveler and the base are inserted into a cylindrical hole drilled through the origin of the spherical golf ball, and secured thereto by glue or adhesive means. The base includes a bottom portion that is a flat plane having a diameter less than the diameter of the golf ball, and being orthogonal to the centerline axis of the hole drilled through the golf ball. A bubble is positioned within a transparent oily liquid within the dome leveler such that when the golfer places the device on a location on a green on a golf course, the bubble indicates the direction that that particular location on the green slants upward.
