Course Caddy, Delaware

It's a caddy in a golfer's pocket. Course Caddy's signature product is the Caddy Card, a book detailing hole graphics, yardage markers, and a record-keeping system that lets players track what clubs they used, how well they performed, and whether or not their golf balls finally hatched. They have courses profiled all across the United States, Canada, and Mexico, meaning golfers can have an edge even on links they're playing for the very first time.
