According to travel blogger Vinh Gau, there are currently three popular forms of scuba diving: snorkeling, scuba diving, and freediving. To have a safe diving trip, you can refer to the following sharing of Vinh Gau - a person with many profound experiences in scuba diving.
1. Snorkeling
Snorkeling is the easiest and safest form of diving for everyone, whether you can swim or not – of course, knowing how to swim is an advantage. All you have to do is lie face down in the sea and watch the small fish swimming around and the colorful corals without much effort.
When diving to see coral, you are always required to wear a life jacket and a mask with a snorkel. The life jacket will help you stay afloat on the sea surface, the mask will prevent seawater from entering your nose, and the snorkel will help you breathe through your mouth so you can comfortably dive to see coral. In some places, you are also provided with fins to help you move in the sea water easier, faster and less exhausted.
To dive safely, pay attention to the following issues:
Double check your equipment: Does the mask fit your face and the fins fit your feet? Does the snorkel work properly? Otherwise, seawater could get into your goggles or into your mouth through the snorkel, making it difficult to enjoy your trip.
Don't dive alone: Although coral diving is very safe, diving alone can be very dangerous when no one can assist you in emergency situations such as seasickness, sunstroke, fainting at sea...
Swim near shore or near boats: Do not swim beyond the sight of lifeguards or boat staff. Always swim in areas under the guidance of professionals, which are usually announced before you jump into the sea.
2. Scuba diving
Scuba diving requires you to carry more equipment such as: air tank, breathing apparatus, life jacket, diving suit...
In addition, there are many other devices that the diving group leaders will have to bring along to ensure the safety of the whole group, including: a diving compass to orient the diving "path", a surface marker buoy to mark the point where passing ships know that there is a diving group below and to let the ship know where to pick up the diving group... Before participating in scuba diving, you need to learn theory and practice at sea with the above equipment to know how to handle the process of scuba diving, and at the same time, you must take skill tests to ensure you are qualified to scuba dive. Once you have a diving certificate, you can use it to register for scuba diving trips all over the world.
Before you go scuba diving, keep these tips in mind:
Check your equipment carefully and cross-check: Don’t be lazy and skip this step because when you are underwater, your life depends entirely on the equipment you are wearing. Always make sure that the air tank valve is open, you can breathe easily through the breathing apparatus, the life jacket can be inflated and deflated easily, the remaining air gauge in the tank is working properly, the goggles fit your face, the fins fit your feet… After you have checked your equipment yourself, cross-check it again with another dive buddy. When everything is good, signal the dive leader to start the dive.
Only dive when you are really okay: Scuba diving is an activity for you to relax in the underwater environment, so you should not strain yourself or try to dive. Only when you feel healthy and mentally comfortable, then "hold the tank (air) and dive into the sea". Only then can you regulate your breathing to stay underwater longer and perform underwater operations more easily.
100% compliance with the dive leader's instructions: You cannot be as familiar with the underwater terrain, strong or weak currents, poisonous marine life, etc. as those who dive every day. With the level and experience of the dive leaders, you should 100% comply with their instructions and the diving plan they give.
3. Freediving
Freediving is the most relaxing of all diving styles because… you don’t need to carry a bulky life jacket or a 20 pound tank. You just need to carry fins, a mask, a snorkel, a wetsuit and a lead, then relax, take a breath, hold your breath and dive into the sea. Unlike scuba diving, with freediving, your relaxation time underwater depends on your ability to hold your breath.
Some points to note when freediving:
Research the area you plan to dive in: Freedivers love to find and explore new dive sites because they don’t have to carry bulky equipment like scuba divers. When you arrive at a new dive site, you can ask the locals about the terrain, currents, depth, etc. to get enough information and come up with a suitable dive plan.
Don’t free dive right after scuba diving: Air bubbles remain in your body for up to 12 hours after scuba diving. So, when you free dive during that time, the water pressure can cause those air bubbles to compress and then burst as they go up, affecting your blood vessels.
Remember to equalize your ears: Under water pressure, your ears will start to hurt - usually after a depth of 3m. This is when you need to equalize your ears to avoid damage to your ears. You need to do this regularly to make your dive as comfortable as possible, don't wait until your ears are too painful to equalize.
conclusion
Those who love the sea and love diving also want to explore and enjoy the colorful and vibrant underwater world. However, depending on your ability to choose the appropriate diving sport. Whatever you play, understanding the knowledge of safety, training and practice will always bring you a lot of experience to have a fun and safe diving trip.
