Vita Bruno has a lot of diving experience, not only in general diving operations, but also in seabed salvage, exploration and so on, and has seen more than one or two shipwrecks.

Now he works as a diving instructor in the "United Forces", and according to the company's requirements, all the company's front-line fighters need to master the most basic diving skills during the training.

As for swimming......

Whether it's the Chinese Army, the U.S. Army, or the guys who retired from the IDF, there is not a single one who can't swim!

Even if you are from the northwest region of China, when you are in the army, you must still learn this swimming.

Zhang Nan learned some common sense of diving from him, and the most concerned was whether the divers would get decompression sickness and be in danger if they worked for a long time in shifts of 30 meters underwater?

"Rest assured, boss, all of our divers have the ability and experience to dive far beyond this depth, and our equipment and diving operations are very well equipped and not dangerous.

Even if there is an accident, such as the need to quickly return to the sea in the case of an unexpected oxygen cut-off, and the body is abnormal, there is also a decompression chamber on board, which can deal with it. ”

Hearing Weta's words, Zhang Nan was a little strange and asked, "Do we have a decompression chamber?"

Needless to say, Thomas said on the side: "The second-hand goods bought half a year after the establishment of the company, and the ones that the Navy updated in the first two years, although the model is a little old, but the maintenance is good, and the training is enough."

This trip to the sea was directly moved, which will be fixed in the No. 3 cargo hold after a simple modification, and can be used at any time......"

Zhang Nan said before that he wanted to build the "joint force" into an all-round security company for the sea, land and air, and gave Thomas enough autonomy, so he didn't think that this guy would even buy professional logistics equipment such as a decompression chamber.

It's a little unexpected, but I'm also more assured of Thomas's ability to do things: I heard him say that the thing was bought for the price of cabbage, and it was counted as Navy scrap, which was more expensive than the price of scrap steel, and I don't know what path this guy has taken.

The people below are doing things well, and Zhang Nan is not stingy, and after listening, he said: "If there are hidden dangers in the performance and safety of the old decompression chamber, I will buy a new one when I go back." ”

The boss is rich, and the big drop is rich!

But even so, Thomas didn't want to spend his boss's money: professional diving decompression chambers were not cheap, and the boss liked to buy the best goods.

It's not a naval hospital and a submarine rescue ship, so you don't have to be so tall.

But Thomas is not an expert in this area, according to the habit of the boss, professional things have to be solved by professionals.

Thomas asked Vita to listen to the professional's opinion.

Vita Bruno is also happy to have a generous boss who cares about the safety of his employees, but he also doesn't want to spend money on it.

"Now this one is enough, even the most extreme decompression treatment, but it weighs a little more.

If possible, the company can go and buy a few sets of portable submersible decompression chambers and medical pressurized chambers, these two new products can be folded, lightweight, suitable for companies of our nature, and the price is not high. ”

"Where can I buy it?"

Zhang Nan asked the key.

"There are domestic producers, and ...... in Florida"

Weta is an American, and the "domestic" he says is, of course, the United States.

Then buy it, whether you use it in the future or not, it's always right to have it, and you don't have to come out like this time, the decompression chamber is loaded on the ship by crane.

Listen to Vita Bruno, the company he knows is also producing portable plateau pressurized cabins and pressurized tents.

Xiang Weirong sighed after hearing this: If only you were a soldier, you would have this thing, the soldiers on the plateau need these.

Well, those things are prepared by the Americans for mountaineering camps or something, and if you are not careful, you have to order them, and the yield is not high: who will buy those things if you don't care!

It will take a day or two for the sediment on the seabed surface to be cleaned up, and Zhang Nan does not plan to stay stupid on the boat, he can take his own yacht to fish nearby today and tomorrow.

"Boss, you have to stay a little farther away, the pump is working here, and the big fish will run a few nautical miles away.

However, the area is rich in fishery, and we asked nearby Indonesian fishermen about it, and you can be sure to have a good time. ”

Or Vita, as the leader of the dive, he has to be responsible for his brothers and the treasure hunt, not just a diver.

As for the fishermen, it's not far from the big islands, and of course there are, and yesterday there were Indonesian monkey boats that came up to sell fresh fish with permission.

After chatting a few more words about the situation in the nearby seas, the corals and fish schools below were very beautiful, and Zhang Nan began to dive again.

"Vita, if I only play shallow water diving, is it dangerous? I can't swim, I'm afraid of water. ”

Hearing this, Vita Bruno smiled and said: "Boss, it doesn't matter if you can't swim, as long as you have the physical strength to make do, the key is to overcome the fear in your heart."

About five nautical miles to the north, there is a large area of sea where the water depth is only two or three meters, and the depth is only seven or eight meters, and the bottom of the sea is relatively flat, which is most suitable for beginner divers.

However, the boss, unlike the general belief that diving is more dangerous the deeper it is, in fact, in the category of recreational diving, the most dangerous is in the shallowest water area of 0-10 meters.

About half of the fatalities occur within 10 meters of water, and more than half of the accidents occur on the surface, most commonly when they are hit by the engines of passing boats when they come out of the water.

There are also divers in our navy who have disappeared or died after getting out of the water, and the people on this ship have realized that there are no people on this boat after they disappeared for several days.

Of course, you don't need to worry about these dangers, boss. ”

Hearing this, Zhang Nan smiled, "Weta, I believe you are the best diver, but you will never become a good recreational diving instructor."

Fortunately, if you go to work as a coach for tourists, I guess you will soon lose your job. ”

Everyone laughs: such a scary instructor is no problem in a militarized institution, but to teach tourists......

Will it scare people away?

Zhang Nan doesn't know, because so far, he has never dived in his life, and he doesn't know if the recreational diving instructor will be scary.

After asking a few words about why the remaining 25% had an accident, Weta said that it was water pressure, of course, this is for amateurs: the biggest hidden danger of the 10-meter depth value is its depth, which is almost 2 pressure values according to the general measurement standard, while 20 meters is 3 pressure values, and 30 meters is 4 pressure values......

The maximum change in pressure from the horizontal plane to the depth value of 10 meters is 200% of the value of the previous depth interval (horizontal plane), and the change value is increased by 1 times!

The pressure varies from 20 m to 10 m and 1/3 from 30 m to 20 m......

Of course, those who can reach 30 meters are already considered masters among amateurs.

After listening, Zhang Nan said with a smile: "Ten meters is so dangerous, then let's play two or three meters, you are going to jail me, and no one will pay you if you drown me." ”

Everyone laughed, and they were ready to go.

There is a lot of diving equipment on board, and even the yacht has several sets of recreational diving equipment.

In such shallow water, more than a dozen or twenty professional divers and swimmers accompany the boss, it is strange that something can happen!
