Patent number: 6547681Abstract: A method of determining a bounce fitting for a golf club for use in sand for a particular golfer, by determining the relative hardness of golf course bunker sand in which the tests are conducted, having a golfer hit a golf ball from that sand thereby forming a divot, measuring the length of the divot, determining the relative depth of the divot, and correlating the divot length, divot depth and sand hardness to determine a desired bounce fitting. The divot length is measured with a device for designating a certain location from which a golf ball is to be hit and for measuring the length of a divot caused by hitting a golf ball from that location.Type: GrantFiled: June 23, 2000Date of Patent: April 15, 2003Assignee: Roger Cleveland Golf Company, Inc.Inventors: Donald C.
