Li Ming-ju, who began studying diving with Huang in 1990, says that Huang originally dived purely for lobster, but that his love of antiques later led him to dive largely for antiquities. He went down as deep as 60 meters, far below the 30-meter floor typical for fishing and recreational dives, and even below the 50-meter limit on salvage from the General No.
1990 年開始向黃加進學習潛水的李明儒表示，酷愛古董的黃加進以前純是為了捕龍蝦而潛水，後來就多是為了找尋古物，下水深度可達 60 公尺，遠超過漁撈與休閒潛水的 30 公尺，甚至超過將軍一號打撈水下 50 公尺的極限。
