IntelliGolf has just added a $10 GPS addon option to their software. I know there are free golf tracking alternatives but IntelliGolf seems to be a full featured product. You can now use your GPS to view distances, track shots, and keep scores. I guess it is pretty much a rangefinder. It even syncs with your desktop and helps you track your bets. It also lets you download scorecards over the air.
From the press release:
IntelliGolf is the only golf software to include all seven S’s of golf: Scoring, Shot tracking, Satellite GPS, Sharing, Sidegames (35+), Statistics (250+), and Signature course (24,000+) scorecards. IntelliGolf is compatible with industry leading GPS-enabled smartphones and receivers. The IntelliGolf software replaces pencil and paper golf scoring, wagering, and statistics gathering on the golf course. Users enter their scores, wagers, and club selection on their handheld/smartphone. IntelliGolf totals all scores, tabulates all wagers, and synchronizes with the included Windows desktop software.
