How COVID affect divers?



A person’s history with COVID-19 is a significant factor to consider when establishing if they are fit to dive or not. This is especially so when considering the hyperbaric and underwater environment as well as the physiological demand of diving. Research has shown that there are structural changes following a COVID-19 infection. These changes can lead to gas trapping, increasing the risk of pulmonary barotrauma.


Note, if you are ongoing any symptoms of COVID-19, they are likely to affect exercise capacity especially aerobic fitness which may make it more challenging to cope with physical demands such as strong current or an emergency during diving. And we know that damage to the lungs can take a while to heal after the initial infection. Hence, divers with COVID-19 symptoms must go back to their normal level of fitness with no evidence of hypoxia (low oxygen) on exertion before they get back into the water.
Although our understanding of the COVID-19 pathogen and its long-term effect on the body is still limited. As such, as the number of people returning to diving after a COVID-19 infection increases, divers must get vaccinated and seek medical advice before going back to the water.


If you have had a positive COVID-19 test, even if you were asymptomatic, there is still a risk of underlying damage to your lungs. For these reasons, several medical personal have agreed that it is safe that such a person does not dive for a minimum of 3 months. After this period, you much have an exercise test with pulse oximetry to check that your level of oxygen has not decreased when you exert yourself. Please note, safety is a priority when diving, even though it may interrupt your diving plans. If you are in doubt, please speak with your local diving referee or AMED for more info about when it’s safe for you to dive.

Cave Diving in the Riviera Maya is one of the most amazing activities you can do if you are a cave diver or you want to become one.


We have plenty of caves where is possible to dive in, cave access is normally simple and the mazes inside are spectacular, with endless variations of formations such as stalactites, stalagmites, soda straw, bacon strips, rim pools, helictites and columns, clear water, low flow, and shallow depth.


Cave diving along the Yucatan coast was discovered in the middle 1980s when cave divers began diving the Cenotes ( meaning natural well ). The exploration of the cenotes exploded as more cave systems were found, surveyed, and mapped, every year since then new caves are found and the number of underwater caves is growing and growing.

We have the world‘s best cave diving, the most extended underwater systems, basically a wonderland for cave divers.

Be prepared! Scuba diving in underwater caves presents a variety of hazards.


General hazards are, water-filled, water temperature and natural daylight cannot penetrate inside the cave than you are in complete darkness.

How to avoid that, carry the right amount of gas based on the rule of thirds or more conservative, fit a proper diving suit to be comfortable underwater for long periods, carry at least 3  powerful diving lights.

Specific hazards:

-water flow ( not in our region as we have low flow systems)

-silt, can be very easy to disturb if you are not properly trained in trim and buoyancy techniques

-haloclines can disturb the visibility pretty much, be aware once you dive in.

-mazes, here we have some kind of swiss cheese caves involving the cave diver in very complex navigation

-Large passageways, can easily create confusion in the direction

-Line traps are not common but you need to check your line to avoid them

-fail to run a continuous guideline, connected to the exit of the cave can result in a fatality

-diving to deep

-diving over the personal and certification level limits

-new places and do not use a map


CAVE DIVING can be pretty safe if you follow the rules, our special advice is to hire a local guide, will be safer, you will enjoy your dive more and he will guide you in the most amazing places you can find.

For noncertified cave divers, our caves are the best to receive a top world training in back mount or side mount, we can teach all the cave diver levels and most Instructor.

If you’re a fan of recreational diving, then you should know that cave diving is an entirely new world. You will need to take different equipment as well as approach if you want to cave dive in Mexico successfully. It is because cave diving in Mexico is challenging and intrinsically more dangerous. Sounds scary? Well, it might be at first because it’s healthy to respect the dangers of the cave. However, the right training and sticking to the rules, you have nothing to worry about even when a difficulty occurs. Here are some things you need to know before you go cave diving in Mexico. 


1. Cave diving stress 

There are a lot of cave courses in Mexico, some of which are more stressful than the others. And as such, it is essential to stay calm, especially when you’re in a stressful situation. There are so many scenarios that could arise while cave diving that could cause stress. For example, problems with equipment, running out of air, visibility problems, losing the line, being stuck, or a combination of the above are known to cause panic in divers. So, in order to get divers prepared, drilling them in such extreme situations before the actual diving is essential. Because in a real case, it will most likely take a while before help comes, so being able to keep calm in the drill will help a lot if a situation arises in the real cave dive. 


2. Scuba Diving training

Another essential skill to have before thinking about cave diving is scuba training. Playa del Carmen scuba diving is a popular and ideal place to start scuba diving training. Why is scuba training so necessary? Well, because in most cave diving, divers use double tanks or rebreathers. So, if you do not have any idea how this equipment works, scuba diving is like a foundation for a start. Additionally, you’d also need buoyancy control and propulsion control for maneuvering in cave diving, which you will master from scuba diving. 


3. Cave diving equipment

Understanding cave diving equipment is also an important thing to know before cave diving all year long: Mexico, an ideal place to start cave diving, with the best season from November till February. However, whenever you decide to cave dive, ensure you get familiar with the equipment and choose the one that you feel most comfortable using.

Sharks are familiar to practically everyone thanks to movies like “Jaws” and the sensational TV documentaries on them that fill up Shark Week every year. Despite this prominence, lots of the “facts” everyone knows about shark behavior are, in fact, misconceptions. If you find yourself fielding shark questions from non-diving friends and you feel the need to set the record straight, here are three apocryphal sharks “facts” you can debunk for them.

shark in Playa del Carmen

1) Human Attacks by Sharks Are Common

No shark in the world tries to kill humans or hunt them as prey. Human flesh isn’t even appetizing to sharks. In the overwhelming majority of shark-on-human attacks, the violence is ultimately caused by a case of mistaken identity. The shark simply mistakes a person for a natural prey animal, like a seal or turtle. A shark will bite a human because its mouth is one of its strongest sensory organs, but it will virtually never try to consume human flesh. However, with larger species of shark, even one “exploratory” bite might prove fatal.

2) Have To Swim Constantly To Stay Alive

Forward motion is important for sharks because of the way they get oxygen. They absorb it straight from the water through capillaries in their gills, so maintaining a constant flow is necessary for their survival. Not all shark species, though, rely on continuous swimming to meet their oxygen needs.
Several shark species, including angel sharks, nurse sharks, and wobbegongs, have mastered a skill called buccal breathing. These sharks suck water into their mouths and then push it out through their gills, allowing them to get oxygen while stationary. Sharks that are capable of buccal breathing spend lots of time lying motionless on the ocean floor.
Other sharks solve their breathing problem by swimming into areas that have strong currents. They let the motion of the water itself move it through their gills, remaining (mostly) stationary. This behavior is especially common in reef sharks in the Caribbean and great whites on the South African coast.

3) Sharks Live Only In The Ocean

The world’s oceans are home to 400 different species of shark. At least two of them, though, can survive in brackish tidewaters and even freshwater rivers. One of these is the rare Byzant river shark or spear tooth shark, which can be found in coastal waters and rivers in New Guinea and northern Australia. The other freshwater-capable shark species is the bull shark, found all over the world. The bull shark, like all fish, is capable of osmoregulation, keeping the concentration of water in its body constant. What sets the bull shark apart is its ability to adapt its osmoregulation to account for the salinity of the water around it. This allows it to thrive in river mouths and even swim upstream into freshwater.

In reality, sharks are hardly the deadly hunters they are portrayed as in the media. Sharks are fascinating sea creatures with complex and curious biologies. Learn more about sharks and help educate your non-diving friends by dispelling the misconceptions discussed above. We hope that this post can help you to something more about shark behavior.

Scuba Diving in Playa del Carmen is a good starting point to investigate whether you like diving because nearby Playa del Carmen there are many places with impressive diving points.

Scuba diving in Playa del Carmen


Recent researches have shown that diving helps divers derive happiness and long-term satisfaction. Improving your skills and virtues in an activity you like can help boost your well-being. Diving can improve your sense of well-being as it enables you to learn more about yourself, other people and the underwater environment around you. There are  Five Major Benefits of Diving:

1- Increase the Knowledge of the Sea

Diving offers many opportunities for divers to increase their knowledge of the sea. This knowledge starts with learning how to dive and continues with improving diving skills after the initial qualification. Also, diving enables divers to know a lot about underwater. This knowledge can help a diver know how to be comfortable under the sea. Diving also helps a diver to know about the unique and marvelous marine life he comes across.

2- Diving Gives A Diver the Opportunity to Travel

Traveling is a good way to increase knowledge and skills through cultural emersion and new experiences. Traveling also results in positive experiences. According to research, positive experiences helps a person get “the good life”.

3- Divers are More Likely to Protect the Environment

People who like diving are more likely to be environmentally aware and undertake pro-environmental behaviors. Apart from protecting the underwater world, divers also protect the environment they live in as they know the importance of caring for the natural environment.

4- Promotes Personal Growth

Diving promotes personal growth as divers share experiences with other divers, bond with fellow divers and what academics refer to as “serious leisure” (leisure activities that promote self-expression, self-enrichment, self-actualization, rediscovering or recreating yourself, creating social connections and a feeling of belonging).

To participate in these activities, a person needs special knowledge, skills, and proper training. People who participate in serious-leisure activities can reach a point where the activity they participate in becomes a central point of their lives and they may start strongly identifying with the activity. I am sure that most of us consider the diving possibility when choosing a travel destination.

5- Creating a Community

As a diver, the friendships you create with your fellow divers will help you grow. Diving helps divers create shared experiences, learn from one another and get out of their comfort zone. Diving together also helps divers grow as families. Research has proven that positive experiences such as socializing and learning are so great that they outweigh negative experiences like poor visibility and bad weather conditions.

Snorkeling or Scuba Diving is not an easy choice.

If you are thinking about hitting the water, and are wondering whether snorkeling or scuba diving is the right choice, it is important to have the proper information. There are distinct differences between the two sports when it comes to everything from training, fitness ability, equipment, and even psychological makeup.

Tortuga seen in scuba diving

Snorkeling allows you to observe fish and algae in calm water

To begin with, think about your purpose for pursuing this activity. Do you want to simply enjoy the recreational time while observing fish, reefs, and algae in relatively calm water? If you are comfortable floating on your stomach, face down in the water as you bob around in the surf, snorkeling is a great option. The diving mask and tube allow easy breathing as you keep your face submerged. If you find that the tube has gotten filled with water, or you decide to hold your breath for a quick dive, it can be easily cleared by blowing hard to expel the water from the tube. People commonly don swim fins, adding more power to kicking legs, allowing you to skim across reefs or dive down a short distance.

Snorkeling does not require any special training

If you want to try snorkeling, you won’t need any special training if you use a safety vest and stick to shallow areas, you don’t even have to know how to swim. When it comes to psychology, if you don’t have a lot of experience swimming or aren’t familiar with water, you can prepare yourself by sitting down in the water near shore floating using your safety vest. However, you must learn to hold your breath for short amounts of time. Then you are ready to head off to explore the undersea world of sea turtles, fish, and shells.

When it comes to safety, the biggest danger when snorkeling is having watercraft such as jet skis not see you, as the only visible indication is a small tube above water. You can improve your visibility by using a snorkel tube that is reflective or applying patches to your safety vest to help others spot you from a distance. It is important to remember to leave shells and coral alone in the water. Never touch!!!

Scuba diving allows you to go underwater and observe sea life

Scuba is an acronym for Self Contained Underwater Breathing Apparatus. It is another way you can work underwater or observe sea life. A knowledge of scuba diving opens up a world of recreational activities, including shipwreck and cave diving, ice diving and cenote trips. The biggest differences between snorkeling and scuba diving are the level of fitness required and the amount of training necessary. Similar to learning how to drive, you will need a professional certificate to prove you understand what you are doing.

Scuba diving requires a specific training

This is issued by the Professional Assoc. of Diving Instructors (PADI). You must also be able to psychologically handle the strain of being underwater with a full mask covering your nose and eyes. You breathe by inhaling and exhaling through a mouthpiece called a regulator that connects to the tank of air you carry on your back. Many destination dive locations and shops can provide you with a four-day course which includes spectacular hands-on dive experiences while you learn. Prices vary greatly, so make sure you research ahead of time to ensure you are getting a good course with licensed instructors.

Cost is another major difference between snorkeling and scuba diving. Snorkeling simply requires a face mask, and an air tube, with optional swim fins. In areas popular for water sports, you can often rent equipment for use during the day for a low price, or find them inexpensively at most sporting goods stores.

A PADI course can provide you what you need to Scuba dive

A PADI course that includes open water experience and dives can run as high as $500 depending on location, however, you can always rent the gear instead of purchasing it.

Whether you opt to scuba dive or snorkel, you are sure to enjoy the fun and relaxation as you experience the magical undersea world and its many enchanting creatures. Think carefully about your budget, expertise level, fitness ability, and how much time you are willing to invest before making your decision.

Diving with a new DPV
Next morning i arrive at the shop and start to check all the equipment to be ready for the day. DPV battery show a full charge , i remove all the weight as i will use it in fresh water , assemble all the parts and switch it on , propeller work , all ok .


I test the Cylinders pressure and EANx % , all perfect , lights on and load all my stuff on the truck , get my coffe with Barby, say good bye and leave Playa del Carmen directed to Ponderosa Cenote.
As soon i get there i meet my friend Albino at the front gate. He know me since years and after explaining to him i will try my new equipment , he let me in with no problem.
Parking lot is not full as always and i find a nice spot on the side. After a good talk with some old friends , i start to set up all my gear and take all of it down to the platform. Nice thing the DPV weight is nothing at all….


I start to dress up my dry suit and than all my xdeep sidemount , ready to go!
I get at the water and jump in it , done the cylinders , do all my safety check and plan my gas for the first dive that will be on the cavern line. I start to descend slowly at 6m and run the engine for few loops to see how it goes , all perfect i clip the DPV on my side and run my primary reel to the cavern line , mark it , start to go .The Piranha is in gear 3 and it is sooo fast , get in 2 and i feel better , i cross with cavern divers and i just cover my primary light to avoid disturbe them.
Now i am alone and want to get in gear 7 to see what´s happen , done , regs in free flow and following the line almost imposible. Four minutes and i feel unconfortable so i switch it off and check gas /time , magically i am at the end of the line and after recording data i start the way back in gear 3 /2 and i feel great.
Diving with a new DPV
Once back at my primary line i recalculate gas and DPV burning time and decide to go on the main cave line , Little Joe direction. I feel really ok with gear 3 and stay on that all time , 10 min later i am at the First cenote , fast gas check and i decide to continue in cave , getting in a large tunnel i get at the first arrow pointing toward another exit and decide to go back at my entrance after recording my data. The “little bastard” is sooo fast and i reach the open water with a lot of gas and burning time left…



I start to scootering in the open water and … i decide to enter the cave circuit from the other side , River Run. Once at the spot i do my plan for Gas and burning time ( depth is not a problem , Avg is 12 m and with EAN32 …), 3min and i am at the cave line , another gas check and go with the DPV at gear 3/4 , fantastic! I get at the 400 Ft marker in a moment , gas check , planty , after the 90 degree i get in the strong halocline , i love that part of the cave , 600 ft marker , 800 , 1000,1200 , gas still ok and burn time too. I continue until i get at the marker direction change , gas and time are more tan enough to complete the circuit but i cannot miss the Halocline zone than… i turn back and run all the way on gear 4 until i get at my reel line , clip the DPV at the d-rings and start to reeling out , i add a 5 min safety stop at my plan. The total time is 90 minutes and i have still 130 bar left in my cylinders , fantastic day…


I get back at the platform and take the cylinders and the “Little Bastard” at the truck , do off my suit and take some pics of my stuff. The day is so hot and i want to go back in the air conditioning to cool off a little .
Diving with a new DPV
On my way driving back at the shop i call Barby to let her know i am alive

Playa del Carmen, Mexico

Playa Del Carmen Mexico located on the Riviera Maya just under an hour from Cancun Airport. This Fishermen’s’ village has become the favorite place for dive vacations because of the underwater river system AND rich coral reefs that are home to an array of sea creatures and rich coral reefs.


The coral reef in the Riviera Maya is the second-longest barrier reef.


There are different levels from 33 feet to 45 feet for diving that allow divers with little experience to experience Caribbean fish like angelfish, parrotfish, stingrays, moral eels and turtles. Some of the deeper sites might require a different level of experience.


There is a mix of things to explore from reefs to wreck diving and of course the famous caverns.


Cavern Diving

You need a normal certification to explore the 15 caverns in Playa del Carmen. You can experience caverns with interesting characteristics and sunlight effects, unusual flora and animals. A certified guiding instructor will escort you through the caverns if you are not familiar with the area.

Cave Diving

Cave diving Playa del Carmen is different from diving through the caverns, you need more than just a basic diving certificate.


With the right certification and experience, you can explore the vast cave systems that are regarded to be some of the best in the world. Your guide should be able to provide you with information on the local regulations that cave divers are required to adhere to

There are different conditions in the caves, some are harder some easier for shallow depth to sediment caves that are fragile and require care when you are diving. The caves have lots of interesting stalagmites and stalactite column formations.

The world’s best cenote diving destination

Playa del Carmen: The world’s best cenote diving destination written by musgrovesheryl One of the joys of scuba diving comes from exploring caves and other formations found close to water bodies. A cenote is a surface connection to an underground water body, frequently found in coastal regions near caves.
Due to the beauty of these underground complexes, many scuba divers have branched into the equally enjoyable sport of cenote diving. While this looks similar to cave diving, it is vastly different in that the divers stick to the natural light zones found in cenotes.

Caribbean delights

One of the best destinations for Cenote diving in Playa del Carmen on the Caribbean coast of Mexico. Apart from the excellent tourist facilities found in the region, it also has some of the most stunning cenotes in the world. The Dreamgate cenote ranks among the most beautiful in the complex and consists of two arms. The Upstream and Downstream arms offer one of the most spectacular dives between stalactites and natural columns.
Also worth considering is the Cenote Tankah that connects one of the biggest underwater cave systems known as Nohoch Na Chich, with the ocean. It is located amidst a mangrove field, giving enthusiasts the sensation of diving beneath the jungle to encounter fauna from the surroundings.


Certified divers

The last and most famous of the set is Cenotes Dos Ojos. The name Dos Ojos is Spanish for two eyes; a reference to two neighboring cenotes connected through a cavernous zone. The first Cenote is the BARBIE LINE and contains a lot of daylight while the second is BAT CAVE LINE and is quite dark, surrounding an air-filled cave in which bats live.
For you to participate in cenote dives, all you need is to be a certified Open Water Diver with a minimum of 20 logged dives and skillful buoyancy control.
If you want to try out some cenote diving in the Playa del Carmen region, look for Pluto Dive, a local provider of quality scuba diving services. Find them on Street 40 between 5th and 10th avenue and will meet all your cenote diving needs.
