Claims20
A device for reading the slope of a golf green comprising
- a) a generally conical body having a top, a bottom that is narrower than the top and at least one side, wherein the bottom has an outer diameter that is smaller than the inner diameter of the grip end of a generally hollow golf club shaft, and the top has an outer diameter that is larger than the inner diameter of the golf club shaft, such that at least the top of the device is retained outside the golf club shaft when the bottom is rotatably inserted into the grip end of the generally hollow golf club shaft;
- b) a pair of positional balance markers disposed on opposite sides of a top portion of the body;

A device for reading the slope of a golf green comprising
- a) a generally conical body having a top, a bottom that is narrower than the top and at least one side, wherein the bottom has an outer diameter that is smaller than the inner diameter of the grip end of a generally hollow golf club shaft, the top has an outer diameter that is larger than the inner diameter of the golf club shaft, and the at least one side is stepped to form an upper step portion adjacent to the top and a lower step portion adjacent to the bottom, wherein the lower step portion fits rotatably within the grip end of a generally hollow golf club shaft such that at least the top of the device is retained outside the golf club shaft;
- b) a pair of positional balance markers disposed on opposite sides of a top portion of the body, wherein positional balance markers comprise raised protrusions disposed on opposite sides of the device that can be felt by the operator;
- and
- c) a means for securing the device in a fixed position in the golf club shaft comprising an expansion tube and a wedge, connected to the device with a bolt and a nut, wherein the expansion tube is a generally cylindrical member adapted at one end for accepting the bottom of the device, and at the other end for accepting the top of the wedge.
