A range finder for a cap for determining the distance to a golf flag (f). The range finder has a cap coupling portion (60) having a thin shell portion (62) adapted to conform with the cap (b) and a pair of "u" shaped portions (64) hooking around the edge of the cap. A base (12) is carried by the cap coupling portion. A first support (20) is pivotally mounted to the base at a second pivot point (28). An index (16) for viewing through the lens is pivotally carried by the second support. The range finder has a linkage bar (36) to the first support and pivotally mounted at a fourth pivot point (40) to the second support. Moving the lens from a retracted position to a flipped-down, in-use position moves the index in unison.
