Abstract: The sonar enabled seeker toy system includes a first and second toy element. The first toy element includes a transmitter generating sub-audible sounds. The second toy unit which is separate, distinct and portable with respect to the first toy unit, includes a receiver. The receiver includes a sub-audible sound detector, a plurality of lights indicating the presence of any detected sub-audible sound and also indicating the signal strength of the received or acquired sub-audible sound signal. In an enhanced system, the receiver or seeker toy unit includes an audio announcer which audibly announces the presence of a high signal strength acquired signal detected by the sub-audible sound detector.
