Hong Tao didn't know, he thought he was going to the library to find some ancient shipwreck materials, and then drove the boat over. At most, buy some detection equipment, no matter how you dive down, anyway, it's a search, and then it's excavation, and if you dig it, you dig it, and if you can't dig it, you change places.

But in fact, submarine treasure exploration is still a very professional technology, since it is an industry, there are naturally insiders and laymen, Hong Tao is a big layman, Mr. Jim and his team are big insiders!

Jim Greg, 49, a native of Florida, is a middle school history teacher and a private treasure hunter. He and his team have been working together for 10 years, and every year from June to November, he takes a vacation time and spends his own boat on the surface of the Florida Peninsula. With very rudimentary equipment and a lot of historical knowledge, he searched back and forth in the sea area that he thought might be valuable, and achieved good results.

In '95, they found a Spanish shipwreck in the waters near Fort Pierce and successfully salvaged some gold coins and ornaments worth $130,000. It was also Jim's team's most successful salvage operation, and he and his team eventually received nearly $100,000 in the property. Unfortunately, most of the salvage has already been sold for money, because treasure hunting under the sea is a very time-consuming and money-consuming job, and if you can't find an investor, you have to pay for it yourself.

Since Singer spread the news that Hong Tao was going to explore the treasure under the sea, 7 or 8 treasure exploration companies and individuals have sent emails to cooperate, including this Mr. Jim Greig. Hong Tao hired him entirely because he had a successful precedent. Compared with those who talk about how they are bullish, Hong Tao is more willing to believe in real results.

But after this Mr. Jim came to Pyramid Island with two of his assistants. did not pay enough respect to the high salary of the rich man Hong, but taught Hong Tao a lesson. It's as if they're not here to be employees, but bosses. Hong Tao didn't get angry this time, because what people said was very reasonable, although he didn't know much about this industry, but as soon as he heard them, he knew that they were not bastards. Respecting knowledge is Hong Tao's consistent style, if you don't know it, then of course you have to listen to the people who know, as for the way others speak. Hong Tao thinks that as long as you don't scold your mother and can let yourself learn, there is nothing unbearable.

According to Jim, ocean treasure hunting is not something that can be started with a boat and a little money, unless you go to the high seas to explore, no matter which country's waters you go to search, you must submit a formal application to the local government, and you must explain the reason for treasure hunting in detail in the application documents before you can obtain a search permit with a restricted area and limited time.

Now that I've got the search permit, the treasure hunting work is just beginning. At this time, you have to conduct a large area search in the area specified in the permit, and you must find evidence that matches your application materials, so that you can take this evidence and then apply for an excavation permit from the marine management department of the local government, and you have this excavation permit. The treasure hunting activity can be regarded as truly entering the substantive stage. So what kind of evidence can be used to apply for an excavation permit? There are many of them, such as an anchor that matches the age, fragments that match the items carried on the ship, and a series of other items.

This is where history and archaeology come in, and you have to be able to determine what age is probably what age. Whether it's from the wreck you're looking for. In addition, you have to find a lot of literature to compare, and if necessary, you have to go to scientific identification. Anyway, it's not as simple as Hong Tao thought, and all steps are stipulated by law. If these regulations are not followed. Then your search and salvage work is illegal. There are also people who do illegal salvage, but it is no different from pirates and thieves, and serious treasure hunters will not agree with it, and 100% of the police will arrest you after discovering it. Moreover, the items you salvaged cannot have legal identity, and can only be sold as contraband, which is another crime, that is, illegal possession and resale, waiting for a lawsuit.

"This is your treasure map! The paintings I drew when I was five years old were much more reliable than these things! You're not just wasting your money, you're wasting our time!" Now Jim is starting to spray at the treasure maps that Hong Tao bought, since you are going to the ocean to explore the treasures, you must have a goal, Hong Tao originally planned to use these treasure maps as a basis, searching one by one, but now it seems that it is not so reliable.

"Mr. Jim, don't worry, since you said that Mr. Hong's treasure map can't be used as a basis, then do you have a treasure map that can be used as a basis, we can spend money to buy it, and then explore it according to your own treasure map. Radha didn't have a good impression of this guy who yelled at Hong Tao at every turn, and immediately stood up to help Hong Tao speak.

"Of course I have, and more than one, but unfortunately I don't have enough money of my own to sustain my exploration. If I provide the location of the treasure, then it will not be an employment relationship between us, it should become a partnership. I use the treasure position to buy shares, you provide funds, and after we find the treasure, we distribute the loot according to the shares. "Jim doesn't look angry, but when it comes to buying and selling, his mind is not impulsive at all.

"That's it, then let's set up a treasure hunting company, according to the way you said, let's explore together. As for the distribution of shares, you go and discuss it with Miss Lada, and make sure that we reach a ratio that is satisfactory to both of us. Now I'm going to prepare the equipment I need first, and I'm leaving!" Hong Tao has been scolded enough in the past two days, and it just so happens that Rada can help him deal with him, so he can hide. As for the shares of this treasure exploration company, Hong Tao doesn't care at all, he just plays, and he doesn't plan to really make a fortune in this industry, it doesn't matter if he has more or less, Lada won't let himself suffer anyway.

Treasure hunting equipment, in fact, should be simple and simple, complex and complex. This thing is the same as fishing, dozens of dollars to get a set of fishing rods, you can also catch big fish, tens of thousands of dollars to get a set of fishing equipment, you can't catch big fish. But there must be a difference between dozens of dollars and tens of thousands of dollars, one is to make do and the other is to be exquisite, Hong Tao has never made do with playing, and must be exquisite!

First of all, you have to have a boat that is not too small, at least 40 feet tall. This condition has been met, the Mouse Superman is enough to take on this task, in order to be more comprehensive and convenient, Hong Tao decided to borrow one of the two coastal patrol boats that Levin found for himself. In this way, if the water is shallow or there are too many reefs, the Mouse Superman does not have to venture into it, and it is just right to drive a patrol boat in.

Secondly, there must be a set of magnetic detection equipment, which can use the changes in the earth's magnetic field to analyze whether there are metal objects in the scanning area. After all, most of the items sought during the treasure hunt are precious metals such as gold and silver, and with it, you can scan a large area of the target sea. This set of equipment can be simple, worth a few thousand dollars, and there are more advanced ones, which can be worth tens of thousands or hundreds of thousands.

Then there must be N sets of diving equipment, and if the target is found, divers are required to dive down to conduct on-site investigations. Unless deep-sea salvage work is carried out, it is generally sufficient to prepare ordinary diving masks, oxygen cylinders, wetsuits, portable metal detectors, and lighting equipment. Deep-sea salvage requires underwater robots, deep-diving gear, and more specialized divers, and maybe something like a deep-sea submarine.

Finally, it is necessary to have the right search and excavation equipment. The seabed is usually covered with sand or mud, especially if you want to dig a shipwreck hundreds of years ago, you must first remove the sand and mud from the surface cover. The bottom of the sea is not like land, you can dig with a spade, once the sand and mud are stirred, the water is foggy, and nothing can be seen, so it is not suitable for manpower to do this kind of work.

Generally speaking, the more rudimentary way is to make two big crutches in the stern of the boat, like the 90-degree bend on the chimney of our stove. Usually this thing is pulled up and placed in the stern, and when used, it is put on the stern propeller with a special bracket, so that the exit of the iron drum is just facing below. At this time, the propeller is activated, and the water will blow to the bottom in the direction of the iron bucket, blowing away the sand and dirt, and when the underwater visibility is restored, the diver can go into the water to search.

But this kind of rudimentary equipment is relatively limited, once the water is deep, say more than 20 meters, 30 meters, it is useless. And its working area is very small, the place that can be blown is more than ten square meters, if you want to blow next to it, you have to remove it to move the boat well, and then install it and continue to blow, which is time-consuming, labor-intensive, and very inefficient. If you want to be efficient, you have to buy professional underwater cleaning equipment, which is like a large vacuum cleaner, the machine is installed on the boat, and one or more thigh-thick pipes are stretched down, which are fixed by the boom on the boat. As soon as the machine starts, the tube will spray water, and the direction and depth of the spray can be adjusted while spraying, as long as it is equipped with enough pipes that can be plugged in, it can be used within 100 depths, and it can also be sprayed while driving the boat.

This kind of equipment also has a function, which is to suck up all the sediment on the seabed. That's right, it's the kind of thing used by the dredger, in fact, the seabed excavation and the dredger clean the river is the same reason, when you need to search, you will reverse the equipment, let the water flow wash away the sediment, and when you need to salvage, turn the equipment forward, and pump up the sediment and the salvage.
