The tool includes a rigid base with an upright rigid post attached perpendicularly to the base a rigid form fitted outer sleeve, measured to fit snug over the upright post. this sleeve allows for height adjustability, also includes a uniquely formed and rigid wand, with a measured, weighted counterbalance end with a small hole to accommodate a bungee cord attachment and on the other end a set and re-settable fix tennis ball mounting the tennis ball itself is mounted on a spindle on a small rod which allows free rotation of the ball for the purpose of ball striking muscle memory development, the ball-mounting wand is bent, geniculate and curved into a question mark like configuration using holes and peg attach the wand to the crown of the form fitted outer sleeve using the counterbalance and the bungee cord the ball can be repeatedly struck, displaced and self reset. |

1. A ball striking practice device which allows a mounted ball to be struck and displaced repeatedly then repeatedly and instantly self rebound and re-set to a predetermined position, primarily adapted to the sport of tennis that is at the same time sufficiently versatile to readily lend itself to any virtually of other ball striking sport comprising:
a base; a rigid upright post affixed to said base; a rigid hollow sleeve measured to fit snugly over the circumference of said rigid upright post, in the well known manner of a fitted sleeve; a tubular wand is bent and geniculated and made rigid, roughly into the shape of an question mark (?); said question mark shaped wand will be mounted in the crown of aforementioned rigid hollow fitted sleeve in a manner such as to be allowed to teeter freely along a predetermined longitudinal line; the head of the question mark shaped wand is the connection and mounting point for a Y-shaped target unit ball mounting; there will be a appropriately weighted counterbalance connected at the tale end, of the question mark shaped target unit mounting wand, said appropriately weighted counterbalance along with a secured yet detachable bungee cord are the means by which the self re-setting of the invention is achieved. |
