Patent ID: 7959526

Claim:
A method for marking the position of a golf ball comprising: a) providing a golf ball position marking device comprising a putting green contact surface, a foaming agent dispensing port, a foaming agent dispensing actuator and a foaming agent reservoir, wherein i) the putting green contact surface is sized and shaped to permit stable positioning of the golf ball position marking device on a putting green in close proximity to a golf ball on the putting green thereby providing oriented alignment of the golf ball position marking device with the golf ball on the putting green; and ii) the foaming agent dispensing port is positioned such that when the golf ball position marking device is positioned in oriented alignment relative to the golf ball, activation of the foaming agent dispensing actuator results in the dispensing of a foaming agent from the foaming agent reservoir onto the putting green at a predetermined vector position relative to the point where the golf ball contacts the putting green; b) positioning the golf ball position marking device on a putting green in close proximity to a golf ball on the putting green; c) aligning the golf ball position marking device with the golf ball on the putting green; d) activating the foaming agent dispensing actuator, resulting in the dispensing of a foaming agent from the foaming agent reservoir through the foaming agent dispensing port and onto the putting green at a predetermined vector position relative to the point where the golf ball contacts the putting green.
