Old Avalon Golf Course is one of more than six thousand courses GolfCore has mapped green by green.

For clubs, the same system runs the tee sheet and the caddie yard — assignments off real tee times, SMS confirmations, and a caddie network that spans every club on the platform. Read how caddie management on GolfCore works.
