ABSTRACT:
A concentration aid for strung rackets used in various sports wherein the object is to hit a projectile, comprising a racket having a head portion provided with a netting matrix, and a handle; a bead made of rigid aesthetic material and having a through-bore. The bead is located in one of the as square openings of the "sweet spot" area of the netting and is held in place by a pair of strings under slight tension and passing through the through-bore and extending on either side thereof, having their opposite ends fastened to the racket frame or to the matrix netting. A projectile striking the bead produces a distinctive vibration felt in the player's forearm thereby helping him or her to properly localize the "sweet spot". The bead does not deviate the trajectory of the projectile on either forehand or backhand strokes of the racket since it is free to retract within the netting opening when struck by the projectile.
