Treasure Hunt Tycoon

Generally speaking, playing free diving requires a diving certificate. Li Du and they work, so a diving certificate is not necessary.

Marins is a very responsible diving instructor. He strongly urged four people to get a diving certificate, because it is not difficult to test this certificate, and three days is enough.

"With my guidance, it won't take me three days. If you study hard, you will be able to get this certificate in two days." Marins told them with confidence.

Just like the driver's license, there are several courses for diving certification in Australia, which are theoretical courses and practical courses.

Marins said that the two days were to get the results of the theoretical class. It took more time to practice the class, and you can pass the test by the way when studying in the water.

This is the benefit of paying a high-level instructor's training course. Marins is also the proctor for the diving exam. He can sign their diving training sheet.

In this way, Li Du and others do not even need to deliberately go to the certification body for reference, as long as they combine the grades of the theoretical class, they can finally come up with their credentials.

Although young, Marins is very experienced in this area.

He found a hotel for the four, which was cheap and located by the sea, with a large ocean diving pool.

The purpose of Marins is that he leads four people to study theoretical lessons. When they are tired, they can take them to the swimming pool to dive, and by the way master the snorkeling and deep diving skills.

The course schedule is 1 + 1, that is, one hour of study, Marlins took them to the pool for an hour of training.

This arrangement can help them save energy and time as much as possible, but the physical requirements are still very high, and the brain and body need to be rotated.

The diving theory lesson is not difficult, mainly two books are the outline, namely the "Open Water Diver's Manual" and the "Recreational Diving Plan User Manual".

All four of them are college students, and Wolf is considered a college graduate, but the college fame he studied is the best among the four. At first, he was required to join the army.

Therefore, the four did not have much pressure to study the culture class. It took only one and a half days to follow Marins to take the exam, and the culture class passed the standards.

They had been learning snorkeling for the last day and a half, and all four would snorkel, but they could swim. In fact, except the wolf brother, the other three did not understand the snorkeling skills and experience.

Even if the skills and experience of Wolf Brothers did not meet the standards, he received militarized training in the army, which belongs to military skills, and everything must be done first.

What Marlins taught them was survival skills, and everything came first.

Snorkeling is the foundation of all diving. In fact, many skills of deep diving and free diving are derived from the snorkeling process.

Li Du was unable to control his body when he encountered the undercurrent of seawater, which was that his snorkeling ability was too poor. The snorkeling ability had to pass the level. First of all, he could still swim freely in the seawater turbulence.

After two days of snorkeling training, after the exam was completed on the third day, Marlins took them to start deep diving training.

Although it was just training, Marins prepared a full set of tools and brought an assistant who was also a diving expert and was responsible for the four people.

The initial training was still performed in the hotel swimming pool, which had a zone water depth of forty meters.

Standing on the edge of the pool, Marins explained to them: "Remember, you must first understand your equipment before entering the water. Equipment is your dependence on underwater survival. They are more important to you than guns to soldiers."

"I told you about the wearing of masks, snorkels and flippers during snorkeling. Now I want to specifically explain the scuba system."

"When diving, the scuba system is the core to support your survival in the water. It has four equipment systems integrated into a single package, buoyancy adjustment system, regulator, oxygen cylinder and counterweight system ..."

He explained the scuba system to four people in detail. Among them, there is a hidden rule when choosing oxygen cylinders, which is the commonly used oxygen cylinders. The cap of the gas cylinder valve is unscrewed and cannot be installed after use.

If the cap of the gas cylinder valve has not been moved, it proves to be a new bottle and can be used directly.

This is already a rule in deep diving, so everyone is required to keep this in mind. Do not put the cap on the cylinder valve for beauty after using the oxygen cylinder.

In addition to these four survival systems, there is a counterweight system during deep diving. This uses lead blocks to offset the positive buoyancy generated by the body and certain equipment. It has a mechanism to discard some or all of the counterweights in an emergency. weight.

The diving suit used during deep diving is simply a diving suit, which has no life-saving ability. Therefore, if you are in danger during a deep dive, you must quickly release the counterweight system and rely on buoyancy to escape from the dangerous waters.

Marins taught them to wear equipment first, this simple, then taught them about the equipment, and finally to maintain and repair the equipment underwater.

The final stage is more troublesome, but it is a skill that must be mastered, otherwise the equipment has a problem in the deep sea. Once it cannot be restored to normal in time, it will often cause a survival crisis.

Equipment training is over ~ www.wuxiaspot.com ~ The next step is to launch.

There are generally three types of launching actions, one step-in, one recline, and one sitting and falling.

Marlins explained to them the launching actions used at different times and under different circumstances. These actions are not only used when entering the water from the boat, sometimes when entering different waters, they must change their posture midway to adapt to changes in water pressure.

Wearing gear, they gradually entered the water.

However, Sophie performed better during the period. She is like a mermaid in the water and can better control the balance of the body. This is the advantage of female diving.

When Li Du dived into the water for about 20 meters, the mask suddenly started to bubble outwards while entering the water.

This made him secretly grieved. He did not expect that such unfortunate things would happen just after training, and hurriedly signaled to Marlins who was accompanied by the water that there was a problem here.

Marins wandered around Hans and didn't seem to notice him here.

Seeing this, Li Du had to keep calm and open the weight system to release the lead blocks and try to swim towards the water.

When he floated up, the wolf brother also floated up, and Malinse followed with Hans and Sophie.

Li Du emerged from the water and said to the wolf brother who followed him, "You don't have to follow me. There is no danger here. You don't have to play the role of bodyguard."

The wolf brother twitched twice, lowered his head and said nothing.

Hans and Sophie then floated up, Li Du asked curiously, "Why don't you train?"

Marins frowned and looked at the two, saying: "Lee and Mr. Wolfgang are very good, and the problem was found in time. The two of you have done very badly and did not take my teaching to heart!" Mobile users please browse Reading, a better reading experience.
