A ball-impact-error sensor/amplifier is bonded to the ball hitting point of a golf club face and includes an adhesive backed base in the form of a soft plastic disc, +E,fra 1/2+EE inch diameterx+E,fra 3/16+EE inch thick, with a center hole that holds a flat-ended, rigid probe +E,fra 1/8+EE inch diameterx+E,fra 1/4+EE inch long, seated upright on the club face so that for the forward swinging club to strike the ball solidly, the club face, probe and ball must compress together squarely at impact, failing which, the probe and wall of the probe base will spring-hinge aside under impact, thereby strongly amplifying impact errors into jarring and blatant mis-hits that must be curbed for ball striking mastery.
