wherein the engagement between the adjustable member and the club head body in the first position creates a first characteristic of the golf club head and the first indicator displaying the first bounce angle for when the adjustable member is engaged with the club head body in the first position and further wherein the engagement between the adjustable member and the club head body in the second position creates a second characteristic of the golf club head which is different from the first characteristic and the second indicator displaying the second bounce angle when the adjustable member is engaged with the club head body in the second position;

wherein:

the first indicator is located on a first protrusion located on the club head body;

the second indicator is located on a second protrusion located on the club head body;

the adjustable member further comprises recesses configured to receive the first and second protrusions when the adjustable member is engaged with the club head body; and

the first and second protrusions prevent the adjustable member from rotating by engaging with the recesses when the adjustable member is oriented in each of the first position and the second position.
