Abstract
A ground-based ball launcher for inflated-ball sports practice provides an impulse that propels the ball upwardly in a trajectory of pre-adjustable angle and velocity so as to obtain a desired maximum height and landing distance offset from the launcher. An optional adjustable time delay gives a player time to move into place and get set for each launching. Launching energy may be provided by a compressed coil spring which can be reloaded by the user with foot-pump action.
