Diving center jolly roger. living under water

For those who have never been diving, it probably seems that this entertainment is the privilege of the “experienced”, and before diving, you must first go through expensive courses, and then also splurge on equipment. Perhaps it is this delusion that prevents many vacationers and residents of the island from considering diving as one of the options for an exciting adventure in Phuket.

I thought so too, until fate brought me to the Jolly Roger. From the divers of this center, I learned that even I, a person who is extremely far from any extreme sports and who can swim exclusively in the "axe style", can dive without prior preparation. And in order not to be unfounded, the Rogers sent me to a depth of 12 meters, the maximum possible for a beginner.

Newbies are allowed

Jolly Roger has been operating in Phuket since 2005. During this time, the company has grown to the largest Russian dive center on the island, acquired branches on Phi Phi and Koh Tao, as well as its own ship.

The "Rogers" regularly arrange various special "immersions", for example, celebrating the New Year under water (video from this event can be viewed here). On New Year's Eve, they plunged a decorated Christmas tree to a depth of 6 meters, around which they then danced round dances and symbolically opened champagne (it is strictly forbidden to drink before and during the dive).

But I went with the Jolly Roger on a weekday basis, along one of the standard routes near the islands of Racha Yai and Racha Noi. This is one of the most popular dive sites in Phuket, interesting for both beginners and experienced divers. There were three newbies in our group: me, a 16-year-old boy and a 9-year-old girl. A separate instructor always dives with children, which ensures that there is no risk.

"Diving is perhaps the safest of the extreme types of recreation," says CEO"Jolly Roger" Evgeny Mukhlygin, - "The whole process takes place in a relaxed state, and the equipment is designed so that air is supplied in any case. Breaking the regulator so that it stops supplying air is simply impossible.

For beginners, of course, a detailed briefing is given, which tells how to dive correctly, why you can’t hold your breath while inhaling when diving, how to clean the air regulator in two ways if it accidentally fell out of your mouth at a depth, how to clean the mask if it got under it water. At the same time, they explain in detail why it is impossible to touch marine organisms. About 400 species of fish and about 200 species of corals live in the depths of the Andaman Sea, under water you can find whale and leopard sharks, turtles, cuttlefish, octopuses, seahorses and millions of tropical fish. Of course, there are predatory and poisonous among them, although, according to divers, marine life does not care about divers, unless, of course, they try to grab a marine life by the gills. That is, even the most dangerous creature in the local waters will not harm you if you do not insist on it.

As I found out when diving, there are no sharks near the Racha Islands, but there are plenty of turtles, exotic fish, octopuses and other underwater inhabitants.

You gave me this world

However, in the first minutes I was not up to underwater beauties. Even before the dive, I admitted that I was prone to panic, and the “Rogers” who listened to this classified me as one of the “difficult clients”. Later, Eugene admitted that many "alarmists" specifically turn to the dive center to overcome their phobias about water.

The first dive off the coast of Racha Noi was planned to a depth of 6 meters. For divers, this is not much, but it was not easier for me to realize this fact. Jambs of unnecessary thoughts raced through my head: “what will happen if the regulator pops out of my mouth”, “what if I’m breathing wrong”, “what if I land on a coral, and there is a stone fish” and so on.

In general, the first dive caused me mixed feelings. But the second - quite unambiguous. Something happened to me that is succinctly characterized by a quote from Pokrovsky Gates: “Kostya, you gave me back this world!”. Only in my case it was not “returned”, but “gave”, and not Kostya, but Misha. An instructor who knows everything about diving, alarmists and youth work methods.

In general, there are no random people in the team of Jolly Roger instructors, everyone has the highest qualifications and great experience. One of them, for example, graduated from the Moscow RGUFKSiT with a degree in Underwater Sports and Diving, while the head of the center himself dived while still in the army.

Back to my second dive. Before him, I immediately remembered the saying that deciding on a second parachute jump is much more terrible than the first. I experienced something similar, but still pulled myself together, which is very glad. The second time, I no longer felt fears, the air regulator in my mouth seemed familiar, I breathed easily and somehow by itself. As a result, I fully felt the beauty of freedom under water.

The second dive took place in a place, without exaggeration, amazing - in Siam Bay near Racha Yai. The place is famous for having two life-size elephant statues and a giant arch with mythical guardians. Unbelievable but true - the Thai government quite deliberately lowered this beauty to the bottom of the sea after the 2004 tsunami, as a talisman and as a memory. So divers who dive in Siam Bay have the opportunity to take absolutely surreal photos as a keepsake.

In general, there are many unique dive sites for certified divers in Thailand. From the wreck of the 85m KingCruiser to the legendary Shark Point, it is safe and amazingly beautiful with a variety of different types of coral, hard and soft corals, leopard sharks and coral fish. There are even whale sharks there, but that's a completely different story.

Unfortunately, most tourists vacationing in Phuket limit their vacation to visiting numerous nightclubs, lazy pastime on the beaches, and contemplation of the magnificent surrounding landscapes. And they don't know how amazingly bright natural beauty located very close to them - in the depths of the sea. But in order to see all this, as they say, you need to go diving. Phuket is rich in a huge number of diving centers that perform a variety of excursions to the underwater world.

The abundance of places suitable for diving makes it possible to get a large number of pleasant experience not only for beginners, but also for experienced divers. I must say that in Phuket you can go diving with almost any level of training, even with the very zero one. An experienced instructor will be able to teach you all the necessary skills for scuba diving in a short time.

There are a lot of diving companies in Phuket. I will list the largest and most well-known companies that have a good reputation and are focused on Russian-speaking clients:

Diving center "Jolly Roger" (website: http://jolly-rojer.ru, Phone: 0810800140)

Argo-Dive Center (site http://argo-dive.ru, phones: 086-277-38-72, 084-716-48-26)

Diversant Diving Center (website: http://diversaint.ru, phone: 0853434944)

Diving center "Joy Dive" (website: http://joydive.asia, phone: 0831810099)

Students can choose any training program for themselves - according to the PADI or CMAS system. Initial classes are held in equipped classrooms, where there is also modern educational literature (including in Russian), video aids and thematic material.

All beginners begin their first trial dives in the pool, and already the first dives in the sea take place near the islands of Phi Phi and Racha Yai. During the day, a group of novice divers, led by an instructor, is engaged in the program. It usually includes several dives and a mandatory lunch on the ship. In addition, the cost of training includes - transfer, equipment, insurance and drinking water. If participants wish, night dives can also be arranged.

Depending on the program chosen by the participant, the cost of training ranges from 5,000 to 15,000 baht. Per day trip with two dives, beginners will have to pay 4,000 - 5,000 baht (depending on the dive site and dive center), certified divers will cost 3,000 - 4,000 baht. But for a three - four-day trip to the Similan Islands, you will have to pay from 16,000 to 21,000 baht.

The dive sites can be reached either by dive boat or by speedboat. The first travel option is extremely comfortable, but somewhat long in time. The second option provides for a faster delivery of participants, but does not provide pleasant delivery conditions.

The best dive sites near Phuket are:

Racha Yai island. A very safe and very easy diving site, excellent for beginner divers. There are practically no high waves and intense currents, but there are hard corals and many beautiful bays. Perhaps the main disadvantage this place is a sparsely represented fauna.

Racha Noi island. It is very similar to the previous one, only here the Southern Plateau is already present with a very intense current. Experienced divers are allowed to dive here. The main advantage of the Southern Plateau is the amazing diversity of the underwater world. You can even see manta rays here.

Phi Phi Islands. This place is perfect for both beginners and experienced divers. Here you can see a huge number of corals, turtles, exotic fish, moray eels and even sharks. The current here is very moderate, and the depth itself does not exceed 30 meters. The only serious drawback of this place is its great distance from Phuket. It takes at least 3 hours to get to the islands on a dive boat, but a speedboat will take you there in less than an hour.

King Cruiser. This is not an island, but the most popular program for experienced divers. Here you can travel to the bottom of the sea to the wreck of the King Cruiser, then to the underwater rocks near the Shark Point lighthouse and to a place called Koh Dok Mai, especially revered by lovers of the underwater macrocosm.

ENRICHED AIR DIVER

PADI Enriched Air Diver is a course for diving with oxygen enriched air.
How is enriched air different from normal air?
The composition of the air that we breathe every day includes 78% nitrogen and only 21% oxygen, and the remaining 1% is other gases. Enriched air, depending on the concentration of the mixture, contains a smaller percentage of nitrogen and a larger percentage of oxygen. This will increase the maximum time spent under water. Let's say your 15m no decompression limit is 90 minutes. But using a mixture with an increased oxygen content, such as EANx36 (i.e. 36% oxygen content), you can increase it to almost 250 minutes.

DIVEMASTER

The PADI Divemaster course is designed for those who have decided to make diving the meaning of their lives.

  • Earn a PADI Advanced Open Water Diver certification or equivalent.

Where to go

There are a lot of diving companies in Phuket. We will list the largest and most well-known companies that have a good reputation and are focused on Russian-speaking clients.

Argo-Dive Center

Training program

Students can choose a program according to the PADI and CMAS systems. Classes are held in equipped classrooms with the provision of modern literature, video aids and thematic material.

Beginners work out a trial dive in the pool. Training dives are held on the islands of Phi Phi, Racha Yai. During the day trip, a group of divers performs a program that includes several dives and lunch on the ship. The price of the tour also includes transfer, insurance, drinking water, equipment. Dives are arranged both at night and during the day.

Price

  • Training will cost from 5,000 to 15,000 baht, depending on the chosen program.
  • The price of a day trip with two dives for beginners will be from 4,000 to 5,000 baht, depending on the company and dive site. The cost of a similar program for certified divers is 3000-4000 baht.
  • A three- or four-day trip to the Similan Islands will cost 16,000-21,000 baht.

Peculiarities

Dive sites can be reached by dive boat or speedboat. In the first case, the trip will be comfortable, but long, and in the second, the duration of the trip will be significantly reduced, but you will have to go in not very convenient conditions.

Best dive sites near Phuket:

Racha Yai Island

It is a safe and easy dive site and is best suited for beginners. There are no intense currents and high waves, but there are many beautiful bays and hard corals. The downside of this place is the poorly represented fauna.

Racha Noi island

This island differs from Racha Yai only in the presence of the Southern Plateau with an intense current. Only certified divers can dive here. The main advantage of the Southern Plateau is the diversity of the animal world. In particular, manta rays can be seen here.

Phi Phi Islands

This place is suitable for both beginners and experienced divers. Here you will find a large number of corals, exotic fish, sharks, as well as turtles and moray eels. The current is moderate, and the depth does not exceed 30 meters. The disadvantage of this place is a significant distance from Phuket. The way to the islands on a dive boat takes about three hours, and on a boat - about an hour.

King Cruiser

A popular program for experienced divers includes a trip to the wreck of the King Cruiser, to the underwater rocks with the Shark Point lighthouse, as well as to a place called Koh Dok Mai, which is of particular interest to fans of the underwater macrocosm.

Keep in mind that it is better to refuse diving in the presence of colds. Beginners are advised to pre-dive a few dives in the pool.
