The Silver Model Volleyball Practice Machine

Has a release point of 5 1/2' high, which makes timing on kills virtually the same as from a human setter. The high release point and pivoting head allows shooting downward to practice digs. A simple dial controls the amount of topspin or underspin. Variable speed control allows you to adjust the speed of the ball from a slow serve to a 60 MPH serve. Moves easily on non-marking casters. Weighs 50 lbs. 110 volt operation. One year warranty on both parts and labor. Made in the USA.
