Abstract
In a method for chasing game, a set of portable sound generators are set out in the field in accordance with a predetermined pattern for chasing the game in a predetermined direction when the sound generators are actuated. Each of the sound generators has a clock associated therewith and means for setting the turn-on time to an accuracy of plus or minus at least a few seconds, such that precise timing of the turn-on time of respective ones of the sound generators is settable, as desired. The turn-on times are then set in accordance with the positions of the respective sound generators in the predetermined pattern so that the sound generators turn on in a predetermined sequence for chasing the game in the predetermined direction.
