Where is a good place to dive in summer?

Abstract: In summer, nothing is more refreshing than playing in the water. Diving is a summer activity that people like. Where is a good place to dive in summer? Domestic summer diving can go to Wuzhizhou, Baifu Bay, Weizhou Island, Panjiakou and Long Island; Foreign summer diving destinations include Thailand-Taodao, Fiji-Mana, Philippines-Dimaya, Maldives and so on. In summer, we should pay attention to gradual diving, from easy to difficult, avoid rushing for success, pay close attention to diving depth, and avoid discomfort caused by diving too deep. Next, let's talk about the knowledge of diving in summer. 1. Where to dive in summer in China?

1, Wuzhizhou

Wuzhizhou enjoys the reputation of "the first diving base in China". The underwater world is colorful and has the best protected ecological coral reef in China. Wuzhizhou is located in Haitang Bay, Sanya, avoiding the typhoon corridor, so it is different from ordinary northern islands. The island is a natural tropical plant kingdom with lush trees, the dragon's blood tree in the dinosaur era. Wuzhizhou is located in Houhai Village, Wanglin Town, 40 kilometers east of Sanya City, about 2.7 kilometers away from the sea, and was called "Guqizhou Island" in ancient times. The east-west length is1500m, the north-south width is1100m, and the area is 1.48 km2 ... The island is covered with mountains and peaks, with trees and flowers everywhere. The visibility of seawater around the island is 6- 18 meters, the corals on the seabed are colorful, and beautiful tropical fish wander around. It is recognized as the first diving resort in China.

2. Baifu Bay

Baifu Bay is located in the southwest of Sanya Yalong Bay National Tourism Resort at the southernmost tip of Hainan Island, about 2 1 km away from downtown Sanya, with Liudao Bay in the west and Sun Bay in the east. Baifu Bay is the main diving center in Yalong Bay, and Dongzhou Island is the second diving spot. The bay is U-shaped, with an annual average water temperature of 26.4 degrees Celsius and an annual average temperature of 28 degrees Celsius. The water surface in the bay is calm, the sea water is crystal clear, and the best lateral visibility can reach18-30m. This means that standing on the beach can already vaguely see the coral reefs on the seabed. Baifu Bay is called "one of the few existing soft coral protection bases in China and the largest in the world" by international environmental experts. At the same time, there are many fish here, such as clown fish, graceful angelfish, colorful butterfly fish and gentle and lovely tortoise. It is the best sea area for leisure diving and is known as "Hawaii in the East".

It's quite abundant to arrange diving activities for a whole day in Baifu Bay. It takes about half an hour from Sanya to Yalong Bay. Do warm-up exercises before going into the water, and keep personal belongings in waterproof bags. If there is a waterproof camera, it is much more convenient to shoot all the time. Wear sunscreen and a sun hat. It's about 2 nautical miles from Yalong Creek to Baifu Bay, and it's estimated to be about one way 1 hour, because people's physique is different. It is best to arrange snorkeling and rest for more than two hours after arriving in Baifu Bay. Tourists can recover well if they are not very energetic. If it is hot that day, they can put off returning until sunset.

3. Weizhou Island

Shiluokou Beach is the best diving base on Weizhou Island. If you are interested, put on a diving suit and dive into the mysterious seabed with the diving instructor. A close contact with the beautiful coral may make your trip to Weizhou Island unforgettable. At Shiluokou Beach, you can rent a sun umbrella and a chair, ask for some cold drinks, lie comfortably under the sun umbrella and enjoy the beautiful scenery while drinking cold drinks. When you are sleepy, you will close your eyes and sleep for a while. When you wake up, you will go to the beach and walk on the waves for a while. Only you are the master of nature here. How to play is up to you.

4. Panjiakou

Panjiakou Reservoir, located in Kuancheng Manchu Autonomous County, Chengde City, Hebei Province, is known as the Great Underwater Wall. The whole scenic spot is 60 kilometers deep, and the Great Wall passes such as Panjiakou and xifengkou are not underwater. Panjiakou Reservoir is located in the west of Kuancheng Manchu Autonomous County. The reservoir was approved by the State Council as one of the important projects of "diverting Luanhe River into Tianjin". It consists of a river dam and two auxiliary dams, with the largest area of 72 square kilometers and the deepest depth of 80 meters. The peaks on both sides of the reservoir are steep and the rocks are like forests, which are very steep.

Xifengkou, where the reservoir is located, is the Xiongguan fortress of the ancient Great Wall. As a part of the Great Wall has been submerged, it has formed the Great Wall Wonder Underwater Great Wall. Diving here is naturally to explore the "Great Underwater Wall". Xifengkou Castle and Panjiakou Castle, which were built more than 500 years ago, were two important passes of the Great Wall in China in Ming Dynasty, and were the throat arteries leading to the northern and northeastern borders in the Central Plains at that time. The Great Wall in this area is about 50 kilometers long and has 265,438+0 piers. Panjiakou Reservoir was built here, and the water level exceeded the height of the Great Wall. xifengkou and Panjiakou Castle were submerged in the water. Since then, the Great Wall, which has experienced 500 years of vicissitudes, has been hidden underwater, waiting for divers to visit.

5. Long Island

On the foggy sea, there are a group of islands as green as jewels. This is the beautiful archipelago miaodao islands, also known as Long Island, which is known as the "Fairy Mountain on the Sea" by the world, facing the ancient city Dengzhou (Penglai) across the sea. Mythological novels such as The Journey to the West's "The Edge of a Mirror Flower" describe this place as an ethereal and detached paradise. The island consists of 32 islands, which is the only island county in Shandong Province and belongs to Yantai City. The island has a land area of 56 square kilometers and a sea area of 8,700 square kilometers. Long Island belongs to the continental climate of East Asian monsoon region, with the characteristics of warm winter and cool summer, and the forest coverage rate of the county is 53.2%. Its unique geographical location and superior natural conditions make it a necessary place for migratory birds to migrate. Every year, more than 200 species of migratory birds pass by, with a number of millions, enjoying the reputation of "post station" for migratory birds and being listed as a national nature reserve. The historical records and legends here, together with spiritual animals and plants, can bring different experiences to diving enthusiasts.

2. Where do you go for summer diving abroad?

1, Thailand-Taodao

If you are a diving enthusiast, you must have heard of the name Taodao! Taodao, also known as Turtle Island, is located in the deep part of the Gulf of Thailand, 65 kilometers northwest of Koh Samui. Its superior geographical location keeps the water temperature of its diving point above 28 degrees all the year round. For divers who want to embrace the sea and explore the seabed 365 days a year, this is a world-class diving destination. There are 28 sea areas suitable for diving around this small island with only 2 1 square kilometer, including 8 kilometers of coral reefs. Every year, more than 65438+ million people who love diving come here to play.

2. Mana Island, Fiji

In Mana Island, Fiji, as long as it is a non-powered play tool, it is generally free of charge. Guests can borrow kayaks for free and row leisurely in the beautiful South Pacific. Go to Mana Island and enjoy the sunshine, white sand and seawater of the South Pacific Island. Snorkeling is the best choice.

Fiji's sea water is clear and transparent, and the seabed resources are very rich. Various corals and a wide variety of tropical fish are dazzling. This is the best place to dive. Don't miss the marine life hidden in red, white, purple and soft corals. Warm sea water and tropical fish are everywhere. The colorful huge coral landscape has long been a world-famous diving resort.

Snorkeling equipment is generally rented free of charge. Soft blue sky, colorful sand, rocks and corals, seawater becomes colorful under the refraction of sunlight. In the sea, in addition to fish, there are cross starfish, small seahorses and tiger-striped shellfish that you have only seen on TV. You may think that you have fallen into the aquarium, but all this is really in front of you.

3. Philippines-DiMaya Island

It is no exaggeration to say that Dimaya Island is a paradise scattered on earth. It is located in Palawan, Palawan province, Philippines. Dimaya Island belongs to a small island in karami's Anse Islands, and its actual location is in the north of Busanga Island in northern palawan island.

Dimaya Island not only has many diving spots, but also can see mermaids in deep water, so it is also called Mermaid Island. Here, in addition to seeing coral reefs and seabed ecology, there are diving spots and Japanese shipwrecks in World War II, which are quite attractive to experienced divers.

4. Maldives

Maldives is located in the place with the most intensive ocean current exchange in the world, and the species and quantity of fish are comparable to those of the Great Barrier Reef and the Red Sea. The biggest feature is that Maldives has specialized institutions to manage diving, and many people often engage in diving.

5. Hawaii-Oahu

Oahu is the third largest island and the most populous island in Hawaii. It is home to 80% of Hawaii's population and is called a "gathering place". It is also the favorite diving place for tourists coming to Hawaii. Shallow water, small waves, plenty of fish and beautiful scenery. There are all kinds of natural coral reefs and tropical fish here.

With its colorful diving shops and resorts, Oahu must be an ideal place for beginners and experienced divers. The number of diving spots is beyond your imagination. These diving spots are only 30 minutes' boat ride from the most prosperous Waikiki Beach.

6. Tahiti

Bora Bora's clear and colorful blue lagoon is a world-class famous diving resort. The waters around the island are warm and calm all the year round, giving birth to a colorful underwater world.

What are the precautions for diving in summer?

1, remember to dive step by step, from easy to difficult, and don't rush for success. Diving is a systematic project. From the amateur who experiences diving for the first time to becoming the highest level diving instructor, the course content of each level is step by step. After learning the corresponding level of courses, you can dive in the waters corresponding to this level. Therefore, for your own safety, please don't rashly challenge high-level waters out of curiosity or other factors before receiving relevant training.

2. When diving, pay close attention to the diving depth to avoid the discomfort caused by diving too deep.

Don't touch the beautiful coral and tropical fish to avoid accidents.

4. Be close to the coach when diving. Be sure to obey the coach's command and follow the principle of two people walking together. The double peer system is one of the important principles of diving. That is, two people should stay together from entering the water to landing (going in and out together). Those with better skills (such as coaches) should not let their companions go ashore alone. People who swim in front (often skilled people) must always look back at their companions and slow down with their body skills. Those who swim behind (such as beginners) should stay behind their companions. Always keep in touch with the coach's gestures.

5. Choose a regular diving enterprise to experience diving activities. Regular diving enterprises must not only have the approved right to use the sea area, but also have various business qualifications, and strictly abide by the operating norms of experiential diving, which can not only ensure the safety of tourists' diving, but also have moderate prices. Don't choose an informal diving enterprise that lacks safety protection measures and safety training for cheap.

6. Please check the equipment carefully before diving. Before each dive, check whether the equipment is suitable and functional, and learn how to use breathing tubes and regulators, how to rest on the water, and how to deal with emergencies.

7, diving, be sure to wear buoyancy control device and pressure gauge, recognize the location of the standby air source and low pressure control inflation system. In addition to self-examination, peers should check each other again to make sure there is no problem. Be sure to thoroughly test the equipment in the shallow pool before diving.

8. Carry your equipment on your back and walk into the sea with your diving partner (beginners should not learn back flips). When the water is waist-deep, put on a diving mask first and help your partner put on flippers. After this, put the regulator in your mouth and start breathing from the second decompression part. Turn back, wipe your feet, and continue to retreat into the sea to prevent tripping due to inconvenient flippers.

9. After arriving at the scheduled diving site, follow the instructor along the natural slope of the seabed and gradually dive into the sea. The depth of the first dive should not exceed six meters. On the way to diving, always observe the water pressure gauge and master your own depth.

Fourth, diving equipment in summer.

You need diving equipment to dive. Simply put, diving equipment can be divided into two categories: light equipment and heavy equipment. Light equipment refers to diving goggles, breathing tubes and flippers-the three treasures of diving. Only these three pieces of equipment are needed for snorkeling. Scuba diving also needs heavy equipment, such as breathing regulator, buoyancy regulator, diving equipment, gas cylinders and other auxiliary equipment.

1, three treasures of diving

Diving goggles, breathing tubes and fins are collectively called the "three treasures" of simple diving, and snorkeling is also translated as snorkeling.

1) mask

A window to enjoy the underwater world. Wear it on your face to cover your eyes and nose. Its main function is to enable divers to clearly observe the scenery in the water. Prevent nasal congestion and balance ear pressure.

Diving goggles consist of lenses, frames, skirts and headbands. Different from goggles, professional goggles lenses are made of pressure-resistant toughened glass with the word "toughened" printed on it, which is very different from ordinary goggles. Diving goggles have a nasal sac for balancing pressure, which can prevent water from entering the nasal cavity. According to the degree of the eyes, the vision orthodontist can wear a diving mirror that suits him, and it is best not to wear contact lenses. The object seen through the diving mirror underwater is 0.33 times larger than the actual size. The most important thing to choose is to fit and suit your face.

2) Breathing pipe

When snorkeling on the water, people can breathe without lifting their heads off the water; In scuba diving, divers can breathe through the breathing tube when resting or swimming on the water surface to save air in the gas bottle. Structurally, breathing tubes can be basically divided into two types: drain valve type and non-drain valve type. From the modeling point of view, there are L-type, J-type, C-type, G-type and so on. The length is usually about 42cm and the caliber is 2-2.5cm.

Attention should be paid when choosing a breathing tube: the bite should be comfortable, otherwise it will cause mandibular fatigue.

3) Fin

Give you a pair of wings that "fly" in the ocean, also called frog shoes, to provide divers with the power to move forward underwater. Different from swimming, diving only depends on the movement of legs, while hands are usually used to do other things (such as underwater photography and manipulating other instruments and equipment). ). According to different purposes and designs, it can be divided into two types: sleeve foot type and adjustable type. Foot-cover diving boots don't need to be worn, just press the number barefoot; Adjustable flippers need special diving boots.

There are also breathing regulators, buoyancy regulators, diving instruments, gas cylinders and other heavy equipment, as well as other auxiliary equipment.

2, scuba diving equipment

SCUBADiving is "scuba diving", which refers to the diving activities carried out by divers with the help of diving equipment such as gas cylinders and respirators.

1) breathing regulator

Breathing regulator (respirator for short) is the key equipment to ensure divers' underwater breathing. It consists of a primary pressure reducer, a secondary pressure reducer and an intermediate pressure pipe. People can't directly inhale the high-pressure air in the air cylinder, but need to automatically adjust the high-pressure air in the air cylinder to a pressure suitable for the diver's depth through the two-stage decompression device of the breathing regulator, and supply it to the diver for breathing. The first stage regulator is made of advanced alloy and used to connect gas cylinders and other equipment; The second thing is to take a bite for breathing. Many divers are also equipped with spare auxiliary equipment.

The second stage of respirator is easy to enter the sediment and needs special protection. Once the sediment enters, it needs to be disassembled and maintained by professionals.

2) Buoyancy regulator (BCD/BCJ)

Buoyancy compensator/jacket or BC-BuoyancyCompensator, that is, buoyancy compensator/vest, in the ocean of three-dimensional space, we will experience the mood of birds soaring in the sky.

Buoyancy control vest is an internationally popular diving buoyancy control device in recent years. It is shaped like a vest, so it is also called a jacket in English. When underwater, the air in BC can be fine-tuned through the inflation and deflation device connected with the gas cylinder through the medium pressure pipe, so that the diver can maintain neutral buoyancy at any depth; Can be used for lifesaving in water. Buoyancy control vest has become a necessary equipment for leisure diving.

3) Diving instruments

Diving equipment is an important equipment to ensure diving safety. There are single, double and triple gauges, which are composed of different combinations of residual pressure gauge, depth gauge, compass and diving calculator, and can integrate data such as depth, direction, temperature and air supply, so that divers can see at a glance.

Residual pressure gauge: used to display the amount of gas in the gas cylinder, so that divers can master the underwater residence time and arrange the diving plan. Divers must get into the habit of checking the residual pressure gauge frequently.

Depth meter: It can display the depth of the diver's current position in the water and the maximum depth of diving. Because scuba divers need to judge whether decompression is needed according to the depth, the depth gauge is a crucial equipment.

Compass: Divers use it to tell directions underwater.

4) Virtual computer

Diving computer is an electronic high-tech product in modern diving instruments, and its functions are very comprehensive. The display contents include depth, diving time, decompression time, rising time, warning of excessive rising speed, water rest time, etc. It can also be connected with PC to analyze and process diving data. The appearance of diving computer makes diving safer and easier to learn. The single submersible calculator is suitable for the double instrument assembly of compass and residual pressure gauge.

Diving instruments are indispensable equipment for divers to dive in open waters.

5) gas cylinder (SCUBATANK)

Gas cylinders are made of steel or aluminum alloy, which can safely store high-pressure air or mixed gas (which can be easily mistaken for oxygen) for divers to breathe underwater.

There are many specifications for the working pressure and capacity of gas cylinders. The capacity of a gas cylinder is usually calculated in liters of water. Common gas cylinder capacities are 8L, 10L, 12L, 14L, etc. The working pressure is 65438 050kg/C, 200kg/C and 207kg/C.. The weight (W), capacity (V), working pressure (FP), pressure measuring date and manufacturer's logo of the gas cylinder are printed on the shoulder of the bottle for users' understanding.

Gas cylinders need to be inspected regularly. For ordinary diving enthusiasts, you don't have to buy your own gas cylinders, but you can usually rent them from diving shops.

3. Auxiliary diving equipment

1) DIVINGSUITS

Made of neoprene (also known as foamed rubber) and chemical fiber fabric. There are diving suits and dry clothes. Leisure diving generally chooses wet diving, and it is best to tailor it.

The role of diving suit is to prevent a large loss of body temperature and keep it. Even if you dive in the hottest days in the tropics, you'd better wear a suitable diving suit, because the temperature in deep water is relatively low and diving activities are not as intense as swimming under normal circumstances. Cold may cause fatigue, unresponsiveness, muscle spasm and other symptoms. Therefore, it is absolutely necessary to have a suit with the right thickness and fit. Secondly, protect the diver's skin from bumps and abrasions; At the same time, the diving suit also has a certain buoyancy.

2) Divination boots

Diving boots, also known as beach shoes, can be worn while diving, and can also be used to walk on beaches and reefs. Diving boots are divided into high waist and low waist in appearance. The non-slip soles and waist of high-quality diving boots are usually made of primary rubber, and the uppers and waist are made of nylon cloth and foam materials specially used for diving, and there is a zipper at one side of the waist. High-quality diving boots generally do not use colored rubber, because using rubber with dyes will age faster and shorten the service life of diving boots.

Diving boots have roughly three functions:

Take care of your feet. When diving, you will inevitably walk on rocks and beaches. Wearing diving boots can prevent feet from being scratched by rough rocks and sharp shells and coral fragments on the beach, and can also prevent feet from being burned by hot beaches.

The soles of diving boots are non-slip, so stepping on moss or other aquatic plants can avoid slipping.

Keep warm, dive in low water temperature, and wear diving boots to protect your feet from frostbite. The diving boots should wear adjustable fins, which can prevent the fins from rubbing against the feet and facilitate the wearing and taking off of the fins.

3) falling in love

Hands are the easiest to be stabbed in various activities, and wearing gloves is the simplest and most effective method. At the same time, it also plays a role in heat preservation.

4) carving knife

Diving knife is a tool for divers to untie fishing line, fishing net or seaweed and defend themselves underwater. Diving knives are generally worn on the side of legs or arms, and are necessary auxiliary tools for diving in open waters.

Diving knives are usually made of stainless steel, with cutting edges and serrated edges, and are equipped with binding scabbard. The size can be selected according to the diver's purpose and preference. Diving suit, diving boots, gloves and diving knives are important auxiliary equipment for diving in natural waters.

5) counterweight and counterweight belt (weight &; Belt)

Counterweight is to balance the buoyancy generated by divers themselves, diving suits and various diving equipment. Usually the counterweight is made of lead and tied to the diver's waist with a counterweight belt. If there are some emergencies that need to be lifted immediately, divers can quickly untie the counterweight belt and abandon the counterweight. It must be emphasized here that it is extremely dangerous to float to the surface too quickly in the water. )

6) diving cap

Prevent a large amount of heat dissipation from the head and protect the head and neck.

7) divine light

The necessary tools for night diving and deep diving, in addition to lighting, can also send out light signals such as asking for advice.

8) Divination board

Before and after diving, data such as non-decompression diving time, decompression diving time, water rest time, repeated non-decompression diving coefficient and altitude diving depth adjustment can be calculated and referenced.
