Living in an archipelago country has many advantages. Besides being able to often take a walk to the beach, you can also try learning scuba diving, which is diving in the sea. However, even though it looks like diving is easy, it turns out there are many things that you have to prepare before taking a scuba diving and sea diving course. What should a beginner know before starting scuba diving? See the information below.
Scuba diving cannot be done carelessly
Diving under the sea is not the same as swimming. Environmental conditions under the sea are very different from in swimming pools or on land. Therefore, you cannot just dive in the water. Before diving in Indonesian waters, you must pocket a certificate of scuba diving issued by diving schools.
So, you really have to pass the course in diving school first, have a certificate, then you can enjoy the beauty of the underwater world of Indonesia or in other countries. The higher your flight hours, the more beautiful waters you can dive into.
What will happen when humans dive under the sea?
Quoted from Cadventura, when under water, warmth in your body will disappear 20 times faster than when on land. Without proper training, you can immediately get cold or experience hypothermia.
In addition, diving can also cause barotrauma. Barotrauma is a condition of injury to the middle ear due to increased underwater pressure. To prevent this, divers usually equalize or equilibrate. This term is used to make the ears adapt to high pressure conditions. The trick is to exhale air while closing your nose.
In fact, when diving you may experience nitrogen narcosis. This happens because there is excess nitrogen in the body so you can lose consciousness. In certain cases, nitrogen narcosis can cause coma. Symptoms of nitrogen narcosis can appear even at a depth of 10 meters.
In essence, even though diving is a fun activity, it does not mean that this activity is without risk. For that, you need adequate preparation before doing scuba diving, can not just jump into the sea just like that.
What kind of preparation should be done before joining scuba diving?
For those of you who have never dived in the ocean at all, there are three main things to consider when you want to take a scuba diving course. For more details, refer to the following information.
1. Competence in water (waterskill)
It is commonplace in sports that are fairly unique and extreme like scuba diving if there are several competency requirements that must be achieved first. This requirement is for your own comfort and safety when diving. In addition, if the requirements have been met or you are competent enough, you will be able to master the diving field much easier.
Quoted from Scuba Diving Intro, there is a test from the Professional Association of Diving Instructors (PADI) that you must go through to see how big waterskillor your competence in water.
First, for 10 minutes you can float or swim to the edge of the pond or stay in the middle of the water without aids.
Second, swim without aids as far as 200 meters or swim as far as 300 meters with diving masks, snorkels and frog shoes. This test will be easy to pass if you are used to swimming. There is no time in this test, so you can swim casually to save energy.
During a diving course, your dive instructor will guide you so you can master the basic skills that are the prerequisites.
2. Health requirements
To get diving certification, you need to be in a healthy and fit state. For that, you need a doctor's letter stating that you meet the health requirements needed before diving. The way to get it is to immediately see a doctor. What should be examined by a doctor? Next is the list.
- Overall health history
- X-ray of the chest
- An electrocardiogram (ECG) to see the electrical activity of the heart
- Lung function
- Audiogram
- Sharpness of vision (eye vision)
- Complete blood test
- Urine test
There may be other health tests that you need to take but not mentioned above. Therefore, contact your diving course to ascertain what health criteria must be met before diving.
In addition, you will be asked to fill out a questionnaire to assess whether there are certain health conditions that might prevent you from diving.
Indeed there are several health conditions that are not recommended for diving. Among them are kelainan in the middle ear cavity, coronary heart disease, and asthma.
3. Learn to know your diving equipment
In addition to physical preparation and medical tests, there is one more thing that is not less important if you want to go scuba diving. Yes, the important thing is to learn to use and master various diving equipment.
You must recognize and understand how each part of the dive gear works. Think of these diving equipment as an extension of your own physical abilities. For example, understanding how the scuba tube hose works to breathe under the sea. You have to know how it works as if the hose is the respiratory tract in your own body. How deep you know the diving equipment can be the key whether you will be successful diving or not.
In addition, you also need to know what risks can occur in these tools and how to prevent them or overcome them when they occur. For example, diving masks must be installed tightly. If you look down and your mask sways, it means you haven't put it together enough and you're at risk of getting water. Ask your diving instructor what can be done if suddenly your mask feels loose when diving.
