Abstract: A jerk rig control device and method are provided for automatically controlling a jerk rig for moving decoys. The device controls the jerk rig by distinguishing target call sounds from one another and from other sounds, and moving the jerk rig in a motion corresponding to the target call sounds. The device includes a microphone that converts different sounds to different sound signals, and a controller that distinguishes between the sound signals to either generate an actuation signal, or to not generate any actuation signal. Optionally, the controller distinguishes between different sound signals to generate different actuation signals that correspond to the different sound signals. An actuator is operable to move one or more hunting decoys in response to the actuation signals.
