one minor problem I've encountered and a solution: some of the courses I play have adjacent teeing areas and the Band app can't always distinguish the correct teeing area. (I think you could program for this; if you've played hole 8, you'd think the device could recognize that 9 is next rather than latching onto, say, the tee for 18, if that happens to be adjacent to 9). One solution is to pause the app by double clicking the action button until you are safely in the middle of the appropriate tee. When you resume active status, the app quickly recognizes the correct tee. Problem solved.
