Note
As a result of the inventive ambitions of Edwin A. Link, Trustee and Vice President of Harbor Branch Foundation, Inc., a unique observation submersible with diver lock-in/lock-out capabilities has been developed. A second generation submersible christened the JOHNSON-SEA-LINK II in January 1976, it exhibits the characteristics of versatility, simplicity, safety, fast turn around between missions, ease of operation and comparatively low cost.
