Sea Hunt

Season 3

Not Rated

Mike Nelson is a S.C.U.B.A. diver in the days when it was still very new. He works alone, and the plot was mostly carried through his voice-over narrations. These gave the show a flavor of a radio program. Typical adventures were finding a downed satellite or sunken treasure.
