Chapter 726: Deep sea dragon

Everyone quickly checked their deep diving equipment and found no problems, very safe!
Immediately afterwards, everyone took off their coats and began to wear deep diving equipment.
In addition to Ye Tian, ​​four other people went into the sea for deep dive exploration this time.
Johnny and Orlando, they are not so much exploring the shipwreck treasure as they are two tourists, it 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 shipwreck treasure, and everything would be fine without adding chaos!
In addition, there are Matisse and Raymond, they will act with themselves, carry out real deep dive exploration, to discover the secrets hidden deep in the sea.
They come from the Delta and the Marine Corps. They all have excellent diving skills, can dive more than 100 meters underwater, and have rich underwater combat experience. They are trustworthy!
Soon, everyone will wear the deep diving equipment neatly.
The body is a three-millimeter thick semi-dry silicone diving suit. The package is very tight. It is black from head to toe with some white stripes on it. The design is novel and unique, full of dynamic!
This diving suit can keep everyone dry during deep dives, effectively prevent heat loss, and avoid being scratched or bumped by protruding reefs and sharp objects on sunken ships.
Its texture is very tough and can prevent attacks by sea creatures! Although the underwater world is very beautiful and charming, it is also perilous! Have to be careful!
Of course, if you encounter terrifying guys such as 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 is reliable!
In addition to scuba diving suits, there are many other deep diving equipment, all available!
The full-mask diving goggles covered with bullet-proof silicone lenses. This diving goggles has a novel design and powerful functions. It is a new high-tech product!
Wearing full-face mask diving goggles, divers no longer need to hold the respirator in their mouths, they can breathe freely in the mask, which is not much different from the sea!
This full-mask diving goggles also integrates a communication interface, allowing divers to communicate underwater, coordinate with each other and take care of each other, and make exploration operations more efficient.
There is no doubt that this is a very good diving equipment, which will definitely give you a lot of help, making this deep dive exploration more effective!
Of course, its price is quite expensive, as high as about $1,000!
Although there are full-face diving goggles, for the sake of safety, you still bring traditional silicone surface snorkels, breathing regulators, back-up secondary breathing equipment, etc., in case you need them.
In addition, there is a backpack-style buoyancy vest, a weight lead belt, and a quad diving instrument, which integrates a pressure gauge, a depth gauge, a compass, and a thermometer!
Each person is carrying two 14L gas cylinders, diving gloves of moderate thickness, diving boots to protect the feet, two huge fins, and essential diving knives!
Then there are underwater lights, underwater recording boards, and diving computers that have only become popular in recent years to ensure that divers stay within a safe depth and time limit and record the diving process.
In addition to these, there are many large and small hooks and quick-release buckles on your body, which are used to carry other auxiliary equipment and are also essential!
After the equipment was neatly worn, Ye Tian and the others had completely changed their appearance, and everyone seemed to have become a deep-sea flood dragon, quite a little imposing!
Miller and Peter were also busy at the stern.
They don't go to the sea, so naturally they don't need to wear diving equipment. The two guys are preparing to go to the deep diving decompression stop with Ye Tian and them.
In the sea, the water pressure will increase by one atmosphere for every 10 meters of depth drop! The greater the depth, the greater the water pressure!
In the depths of several tens of meters, the water pressure is very terrifying, and it is absolutely human to bear!
Ordinary people without deep diving training can only dive about 30 meters underwater, which is the limit of most people!
When diving deep, divers on the bottom of the sea must not rise quickly, they can only surface slowly and at a constant speed, allowing their bodies to gradually adapt to changes in water pressure!
Only in this way can decompression sickness be effectively avoided!
If you float up quickly, and the gas dissolved in your body can't be expelled from the body with breathing, bubbles will form in the tissues and blood. This is decompression sickness. The milder will be injured and the severer will die. You must not ignore it!
As the name implies, a deep diving decompression stop is a decompression station that sinks into the sea, allowing divers to stay at a prescribed intermediate depth for a period of time. This is called a safety stop, or a decompression stop!
After 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 pay the sea surface safely.
The decompression stop prepared by Miller and the others will be controlled by the winch in the yacht house and suspended in the sea with steel cables to provide services for Ye Tian and the others who are diving and exploring.
In addition to being a decompression stop suspended in the sea, it is also an offshore platform that provides various supports for Ye Tian and the others.
The stop will carry many spare gas cylinders for their use.
This allows them to stay on the bottom of the sea for a longer time and explore more areas without frequent travel between the sea surface and the bottom of the sea, which adds a lot of unnecessary risks!
In addition, the stop also carries underwater communication equipment, which is connected to the yacht on the sea through cables, so that everyone can communicate with each other and understand each other's situation!
In addition to these, there are some other items on the stop, not only the equipment needed for deep diving, but also underwater weapons, such as spear guns, underwater rifles, etc., in case of emergency!
Who knows what you will encounter underwater later, in case you encounter a shark, or other divers with unpredictable hearts, these things will come in handy!
Looking at the full-mask diving goggles in his hand and the deep dive decompression stop that is about to be completed at the stern, Johnny couldn't help but said with emotion:
"Steven, what you have prepared is so full, it is absolutely perfect! Admire it!"
"I really didn't expect that deep diving is so particular! Need so much equipment, today is an eye-opener! It seems that we only learned a little bit before, and did not have any contact with real deep diving!"
Orlando was also very emotional, with expectations in his eyes, wishing he could go to sea immediately.
"Before you learned about recreational diving, it's just that the depth is a little bit larger! The depth of 50 or 60 meters is already commendable!
This time we are going to explore the shipwreck treasures under the sea. The depth is greater. It is a veritable technical diving. Of course, it can’t be the same, and it’s not comparable!
What you see is only part of the deep diving equipment, some special equipment has not appeared yet, when those equipment appear in front of you, you will definitely be more shocked! "
Ye Tian said with a light smile, his expression was very relaxed.
"Ah! There are still equipment, what are they? Get it out quickly, and let us open our eyes!"
Johnny and Orlando said in unison, scanning around, very excited.
As soon as the voice fell, Pique and Kenny walked up from the bottom deck, holding a lot of equipment in their hands, and placed them in the living room!
After putting things in place, Matisse immediately began to introduce these equipment and guide everyone to wear them one by one.
The first is more than one meter long and more than 30 centimeters in diameter. The tail is equipped with a propeller and two handles that are skimmed outwards. It looks like a pocket torpedo for a fully wet submersible propeller.
"This is a fully wet submersible thruster. After it is activated, it can take us forward, increase everyone's mobility under water, and greatly save energy, allowing everyone to stay on the bottom of the sea for a longer time!
When using the thruster, you must pay attention to several points. The first is the battery consumption. 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 one time, it is best to keep one-third or one-fourth of the power, so that you can use the thruster to return to the sea smoothly, otherwise it will be a big trouble!
The speed and direction of the propeller must be controlled, not too fast to avoid accidents! Especially when you are floating or diving, you must pay more attention to speed control, otherwise it is very dangerous!
There is a strong light searchlight on the front of the thruster, which can provide lighting for everyone, and there is a small spare gas cylinder in case of emergency. It is best not to use it until the last minute.
There are two traction ropes at the tail, connected to two quick-release locks. After going into the sea, everyone connects the locks to the locks on their belts and starts the engine and it is ready to use! "
At the same time that Matisse introduced, everyone had stepped forward and 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 a P11 underwater silent pistol made by a German, a very sophisticated underwater weapon. Equip it, maybe it can be used underwater!
There is also a diving saber here. It is a special diving knife used by the Delta Force. It is sharp enough to deal with ordinary beasts in the sea. It can also be used to break down obstacles! Many functions! "
"Ok!"
Ye Tian nodded in response, then took the box and opened it, took out the P11 underwater silent pistol, tied it with the holster to the right thigh, and stretched out his hand to shoot!
Raymond did the same, quickly opened the box and equipped this special weapon.
Seeing this peculiar special pistol, Johnny and Orlando immediately shined, looking at Matisse expectantly and saying:
"Matis~EbookFREE.me~ will you give us two too? This thing is so cool, it must be very powerful, and we want to experience it too. It must be very exciting!"
Unfortunately, Matisse shook his head and rejected them.
"I'm afraid not! Guys, this is a special weapon, there are not many in total, the ammunition is very limited, one less one can only be used on the blade, so it can't be equipped for you!
There is no problem with special diving knives. You can equip one for each of you. I believe this is enough to ensure your safety. Leave the rest to us, don’t worry! "
"Well, it seems that this can only be done!"
Johnny nodded in response, somewhat regrettable.
Next, Matisse introduced several other pieces of equipment and guided everyone to wear them one by one.
Within a few minutes, everyone put all these equipment on their bodies.
Immediately afterwards, Ye Tian installed the underwater camera and underwater camera used to photograph the bottom of the sea on his head and right shoulder, respectively.
A strong flashlight is tied to the left and right forearms respectively, so that you can follow your eyes wherever the arm is pointing.
At the stern side, the deep diving decompression stop is ready.
Everything is ready, you can start deep dive exploration at any time!
