A portable handheld device for collecting and displaying golf round data. The data collected for each stroke includes the location, time and club used and the resulting ball position achieved. Locations on the golf course are determined by radiolocation. Data transfers between the handheld device and external storage are by direct connection or cellular telephone or some other wireless link. Before each drive or approach shot, player performance and course distance information are used to help the player choose the correct club. Putt break prediction is provided before putting strokes. Information that a stroke has been taken and which club was used can be entered manually by the player or sensed automatically from telemetry equipped golf clubs. Golf round data collected is used to produce play souvenirs, records and analyses. Any selected stroke in a round can also be replayed on a graphical display of the handheld device.
