The invention is a card in the form of an accurate scale map of one or more complete holes of a golf course - tees, fairway, nearby rough and green, and including two kinds of intelligence. One of these is all of the principal landscape features of the hole such as trees, bushes, bodies of water, and artificial hazards such as sand traps. The other type of intelligence is a set of markings or indicia superimposed at convenient intervals on recognizable parts of such landscape features, together with written intelligence identifying the true distance between each indicium and the golf player's goal - the cup or center of the green. The preferred form of indicia are circular arcs drawn with the cup or center of green as a center, so that the indicia may be extended from a selected landscape feature all the way across the fairway, with the distance of that arc from the cup written in yards. These arcs are spaced along the length of the fairway at convenient intervals which depend on the frequency of identifiable features, preferably spaced from one another in the range of 25 to 100 yards.
