ABSTRACT:
A tennis instructional device having telescoping tubes which permit a user to raise or lower the position of tennis balls in order to practice his or her tennis strokes and serves. The tennis balls are cooperatively held perpendicular to the telescoping tubes by a sleeve and an arm. The sleeve journals the telescoping tubes and can be positioned higher, or lower, on the telescoping tubes by an assembly of holes which pass through both the sleeves and the telescoping tubes. A user may pass a pin through the hole to temporarily fix the position of the sleeves, on the telescoping tubes, and the relative positions of the telescoping tubes to one another. The arms are received by the sleeves and the tennis balls are held at a distance from the arms by a resilient material that will return the tennis ball to its original position after being struck by a user's racquet.
