Everyone quickly checked their deep diving equipment and found no problems. It was very safe!
Immediately afterwards, everyone took off their coats and began to put on deep diving equipment.
In addition to Ye Tian, there were four other people who went into the sea for deep diving exploration this time.
Johnny and Orlando, instead of exploring the sunken treasure, are more like two tourists, that seems more appropriate!
Ye Tian never expected these two guys to be of any help to him, nor did he expect them to discover the sunken treasure. If they didn't cause trouble, everything would be fine!
In addition, there are Matisse and Raymond, who will act with them to conduct real deep-diving explorations to discover the secrets hidden deep under the sea.
They are from the Delta and the Marine Corps respectively. They all have excellent diving skills and can dive to a depth of more than 100 meters. They also have rich underwater combat experience and are trustworthy!
Soon, everyone put on their deep diving equipment neatly.
The next body part is a three millimeter thick semi-dry silicone wetsuit, which is very tightly wrapped. It is completely black from head to toe, dotted with some white stripes. The design is novel and unique, full of dynamic!
This wetsuit can keep everyone dry during deep dives, effectively prevent heat loss, and can also avoid being scratched or bruised by sharp objects on protruding rocks and sunken ships.
Its texture is very tough and can prevent attacks from sea creatures! Although the underwater world is very beautiful and charming, it is also full of dangers! Have to be careful!
Of course, if you encounter scary guys like bull sharks or great white sharks, no matter how tough the diving suit is, it will be useless. At that time, it mainly depends on strength and luck, and nothing else can be relied on!
In addition to scuba diving suits, there are many other deep diving equipment, all available!
A full-face diving goggle covered with bulletproof silicone lenses. This diving goggle has a novel design and powerful functions. It is a high-tech product that has just been released!
Wearing a full-face diving goggle, the diver no longer has to hold the respirator in his mouth. He can breathe freely in the mask, which is not much different from the sea surface!
This full-face diving goggle also integrates a communication interface, which allows divers to communicate underwater, coordinate and take care of each other, and make exploration operations more efficient.
There is no doubt that this is a very excellent diving equipment, which will definitely bring a lot of help to everyone and make this deep diving exploration more effective with half the effort!
Of course, it’s quite expensive, up to about $1,000!
Although there are full-face diving goggles, for the sake of safety, everyone still brings traditional silicone surface snorkels, breathing regulators, backup secondary and other breathing equipment in case of emergency.
In addition, there are backpack-type buoyancy-adjusting vests, lead weight belts, and four-link diving instruments, which integrate a pressure gauge, depth gauge, compass, and thermometer!
Each person carries two 14L gas bottles, wearing diving gloves of moderate thickness, diving boots to protect the feet, two huge flippers, and the essential diving knife!
Then there are underwater lights, underwater record boards, and diving computers that have only become popular in recent years and are used to ensure that divers stay within safe depths and time limits and record the diving process.
In addition to these, there are many large and small hooks and quick-release buckles on everyone's body, which are used to carry other auxiliary equipment and are also essential!
After wearing their equipment neatly, Ye Tian and the others have completely changed their appearance. Everyone has turned into a deep sea dragon, quite imposing!
At the stern of the boat, Miller and Peter were also busy.
They don't go into the sea, so they don't need to wear diving equipment. These two guys are preparing to go into the sea with Ye Tian and others at the deep-diving decompression stop.
In the sea, for every 10 meters the depth drops, the water pressure increases by one atmosphere! The greater the depth, the greater the water pressure!
At a depth of tens of meters under the sea, the water pressure is so terrifying that most people cannot bear it!
Ordinary people without deep diving training can only dive about 30 meters underwater at most. This is the limit for most people!
When deep diving, divers on the seabed must not surface quickly and rashly. They can only surface slowly and at a constant speed to allow the body to gradually adapt to the changes in water pressure!
Only in this way can decompression sickness be effectively avoided!
If you float up quickly and rashly, the gas dissolved in the body will not have time to be expelled from the body with breathing, and bubbles will form in the tissues and blood. This is decompression sickness, which can cause injuries in mild cases and death in severe cases. It must not be ignored!
As the name suggests, a deep diving decompression stop is a decompression station sunk into the sea that allows divers to stay at a specified intermediate depth for a period of time. This is called a safety stop, or a decompression stop!
Wait until the diver gradually adapts to the changes in water pressure and gradually discharges the high-tension inert gas from the body, then he can continue to float and return to the sea safely.
The decompression stop prepared by Miller and the others will be controlled by a winch in the yacht garage and suspended in the sea with steel cables to provide services for Ye Tian and others who are exploring deep dives.
In addition to being a decompression stop suspended in the sea, it is also an offshore platform that provides various supports to Ye Tian and the others.
The stops will carry many spare gas bottles for their use.
This allows them to stay on the seabed for a longer time and explore more areas, without having to travel frequently between the sea surface and the seabed, which adds a lot of unnecessary risks!
In addition, the stop also carries underwater communication equipment and is connected to the yachts on the sea through cables, making it easier for everyone to communicate with each other and understand each other's situation!
In addition to these, there are some other items at the stop, including equipment required for deep diving and underwater weapons, such as spear guns, underwater rifles, etc., in case you need it!
Who knows what we will encounter underwater later. If we encounter sharks or other divers with ulterior motives, these things will come in handy!
Looking at the full-face diving goggles in his hands and the deep-diving decompression stop that was about to be prepared at the stern of the ship, Johnny couldn't help but said with emotion:
"Steven, you are so well-prepared, it's almost watertight! I admire you!"
“I really didn’t expect that deep diving is so particular! It requires so much equipment, today is an eye-opener! It seems that we have only learned a little bit before and have not been exposed to the real deep diving sport at all!”
Orlando was also very emotional, his eyes were full of anticipation, and he wished he could go to the sea immediately.
"What you were exposed to and learned before was probably recreational diving, but the depth was just a little deeper! Being able to reach a depth of fifty or sixty meters is already commendable!
This time we are going to the bottom of the sea to explore sunken treasures. The depth is greater. It is a veritable technical diving. Of course, it is not the same or comparable!
What you see is only part of the deep-diving equipment. Some special equipment has not yet appeared. When those equipment appear before your eyes, you will definitely be even more shocked! ”
Ye Tian said with a chuckle, looking very relaxed.
"Ah! There is actually equipment, what are they? Take it out quickly and let us open our eyes!"
Johnny and Orlando said in unison, their eyes darting around, very excited.
As soon as he finished speaking, Peake and Kenny came up from the bottom cabin. They held a lot of equipment in their hands and put them in the living room!
After putting the things away, Matisse immediately began to introduce the equipment and instruct everyone to wear them one by one.
First of all, it is a fully wet submersible propeller that is more than one meter long and more than 30 centimeters in diameter. It has a propeller and two handles tilted outward at the tail. It looks like a pocket torpedo.
“This is a fully wet submersible thruster. Once activated, it can take us forward, increase everyone’s mobility underwater, and also greatly save physical energy, allowing everyone to stay on the seabed for a longer time!
When using the thruster, you must pay attention to several points. The first is the battery usage. The battery in the thruster can support three to four hours of diving operations. I think this should be enough!
Never use up the battery at once. It is best to keep one-third or one-fourth of the power so that you can use the propeller to return to the sea smoothly, otherwise you will be in big trouble!
The speed and direction of the thruster must be controlled and should not be too fast to avoid accidents! Especially when floating or diving, you must pay attention to controlling the speed, otherwise it will be very dangerous!
There is a strong searchlight at the front of the thruster, which can provide lighting for everyone. There is also a small spare gas bottle in case of emergency. It is best not to use it until the last moment.
There are two traction ropes at the tail, connected to two quick-release locks. After going into the sea, everyone can connect the locks to the locks on their belts, start the engine and use it! "
While Matisse was introducing, everyone stepped forward and each picked up a propeller and studied it carefully. Everyone was very interested!
Introducing the completely wet propeller, Matisse picked up two more boxes and handed them over.
"Steven, Raymond, this is the P11 underwater silent pistol made by the Germans. It is a very sophisticated underwater weapon. Equip it, maybe it can be used underwater!
There is also a diving saber here, which is a special diving knife used by the Delta Force. It is extremely sharp and can deal with ordinary sea beasts. It can also be used to break obstacles! Lots of features! "
"Okay!"
Ye Tian nodded in response, then took the box, opened it, took out the P11 underwater silent pistol, tied it and the holster to his right thigh, and he could pull it out and shoot!
Raymond did the same, quickly opened the box and equipped this special weapon.
Seeing this special-looking pistol, Johnny and Orlando's eyes immediately lit up, and they looked at Matisse expectantly and said:
"Matisse, would you like to give us two too? This thing is so cool and must be very powerful. We also want to experience it. It must feel very exciting!"
But unfortunately, Mattis shook his head and rejected them.
"I'm afraid not! Guys, this is a special weapon. There are only a few of them. The ammunition is very limited. One is used and one is missing. It can only be used on the blade, so it cannot be equipped for you!
There is no problem with special diving knives. We can equip each of you with one. I believe this is enough to ensure your safety. Just leave the rest to us. Don’t worry! "
"Well, it seems that's the only way to go!"
Johnny and the others nodded in response, feeling somewhat regretful.
Next, Matisse introduced several other pieces of equipment and guided everyone to wear them one by one.
Within a few minutes, everyone had put all these equipment on their bodies.
Immediately afterwards, Ye Tian installed the underwater camera and underwater camera used to take pictures of the seabed on his head and right shoulder respectively.
A strong flashlight is tied to the left and right forearms respectively, so that you can use your arms to move your fingers. Wherever your arms point, your eyes can follow.
Over at the stern of the ship, the deep dive decompression stop has been prepared.
Everything is ready and you can start deep diving exploration at any time!
