121	Follow through indicator for bowlers	US700306	1976-06-28	US4059267A	1977-11-22	Howard E. Noble
A follow through indicator for bowlers comprising a planar base element on a wristband for fastening to a bowler's arm, preferably adjacent the wrist, such that the base element is disposed in a plane parallel to the plane of the path of the bowler's arm during delivery and throw of the ball. An indicator element such as a pendulum bar is pivotally mounted on the base for movement from an initial rest position to a position indicating that a proper follow through has been made, the base serving to guide movement of the indicator along a path generally parallel to the path of the bowler's arm during delivery and throw of the ball. The device includes holding means such as magnets on the base element, in which case the pendulum is magnetically attractable, for holding the indicator element once it reaches the position indicating proper follow through, for convenience in inspection.
