  • Patent number: 5509650
    Abstract: An apparatus and method for improving the scoring skills of a player practicing a sport, such as hockey, ringette, broomball, soccer and lacrosse, involving propelling a playing piece into a goal tended by a goalkeeper is disclosed. A target support is sized to approximate the goal and at least two targets positioned thereon are representative of areas which are typically unprotected by a goalkeeper in a common goal guarding position. A sensor detects a player in a predetermined area proximate the target support and generates a signal to a processor which executes a program to indicate at least one of the targets as a current target for which the player should aim. The current target indicator is activated for a predetermined period of time, for example dependent on the skill of the player, or until the playing piece successfully strikes the current target. The processor preferably accumulates statistics useful in gaging the skill progression of the practicing player.
