This show was set in Hawaii so CBS television studios could re-use lots of the sets from its other hit show, Hawaii Five-O which in fact had just finished its on-air run in 1980.

A number of earlier episodes reference the imaginary Five-squad, setting this series within the exact same "world" as Hawaii Five-O.

As a result of crossovers with other programs, the series is also found to take place in the very same world as Murder, She Wrote and Simon and Simon, among others.
