What GolfCore has for Duff House
GolfCore's library covers Duff House Royal green by green: 16 putting surfaces traced with 252 elevation contours from 1-meter national lidar elevation data. The steepest measured slope on these greens tilts at 14.0 percent — the difference between a putt that dies at the hole and one that runs four feet past.
In the app, players and caddies read the same data live on the course: contour bands with fall-line arrows, wind simulated at the player's position, and pin positions that clubs on GolfCore set each morning. Duff House Royal is one of more than four thousand courses mapped across all fifty US states, Britain, and Ireland.
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.
