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, you can not just jump into the sea recklessly. What kind of preparation should be done before you take scuba lessons?
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. Competency in water (water skills)
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 fulfilled or you are competent enough, you will be able to master the diving field much easier.
There is a test from the Professional Association of Diving Instructors (PADI) that you must go through to see how good your water skill or competency is in the 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 diving instructor will guide you so you can master the basic skills that are the prerequisites.
2. Health requirements
In order to get a 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?
Here are things that doctors will examine:
Overall health history.
An electrocardiogram (ECG) to see the electrical activity of the heart.
The sharpness of vision (eye vision).
Complete blood test.
There may be other health tests that you need to go through but not mentioned above. Therefore, contact your diving course to ascertain what health criteria that 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 which are not recommended for diving. Among these are abnormalities 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. The important thing is to learn to use and master various diving equipment.
You must recognize and understand how each part of the diving gear works. Think of this 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 inside your body. How good 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 have risk of water getting inside of it. Ask your diving instructor what can be done if suddenly your mask feels loose when diving.
