Phil masters has been a history lover since he was a child. He has always dreamed of finding treasures under the sea. After several years of ideological struggle, 1977, at the age of 40, he finally quit his job, moved his family to Florida in the southern United States, and began to learn how to find underwater treasures. Masters has set up an "international salvage company". First, a sunken British frigate 17 1 1 was found near Nova Scotia, and some shillings were fished out. Later, he found a ship regarded as "revenge of Queen Anne", which was the flagship of the famous "Blackbeard" pirate fleet. This siren was once rampant in the18th century. After drifting at sea for more than ten years, masters thought he was about to reach the peak of his career: he discovered the Spanish galleon El Salvador. The ship disappeared off the coast of North Carolina at 1750. It was loaded with 89,200 pounds of cocoa, 240,000 pounds of silver coins and gold pesos. "I want El Salvador to be as famous as Titanic!" This is the driving force that drives the master and hundreds of gold diggers to go to sea. It is not enough to find the treasure on the seabed with advanced detection equipment. Treasure hunters also need to fully investigate and study historical materials. Jack haskins, a gold digger in Florida, often goes to the state archives to consult historical documents, focusing on the letters and cargo lists of the shipwrecked captain. He is currently tracking down the whereabouts of a Spanish fleet that crashed in Cuba in 17 1 1. Spain is a very bureaucratic country, and the captain should record all the big events and small feelings that happen every day in triplicate and report them to the king. Haskins hopes to find some evidence and finally determine a treasure map. Masters found "Revenge of Queen Anne" through the court records of 17 19: Blackbeard's men mentioned in court that the ship had docked in Beffort, North Carolina before sinking. So, with the help of the US Army Engineering Brigade, masters carefully inspected the changes of waterways near Beffort in the past century. Masters claimed that he was "only a second-rate diver, but he was an excellent scholar." He prefers to be called a "marine historian" because what he salvaged is a glittering shipwreck history. Underwater gold customers not only salvage "sunken wealth", but also make full use of the historical value of sunken ships to make money. RMS Titanic Company, the legal fisherman of Titanic, has sold the exclusive right to display the articles on board to SFX Entertainment Company for $8.5 million per year. Masters thinks he can also make money from Revenge of Queen Anne, although there is nothing valuable on it. "The name' Black Beard' is a big selling point in itself. Few people in history can make people so afraid. " Masters also plans to produce a four-part TV series about pirates and sell copies of the goods on board, including a syringe, which is said to be used by Blackbeard's men to inject themselves with mercury to treat syphilis. From this point of view, the right to shoot and the physical exhibition are the best ways to make profits from sunken ships. The salvage company claimed: "The movie box office and video revenue of Titanic earned more money than salvaging any sunken ship." In addition, some companies also use the Internet to sell sunken ship souvenirs. "Melf House Treasure Hunting Website" advertised "You can have a history" and sold the silver toothpicks on the sunken ship at a price of $45 each.
