What should you expect?
The critical academic side is the first step to learning how to scuba dive on the PADI open water course. The e-learning also comes in various languages; you can choose your preferred language.
E-learning makes this easier by allowing you to study at your pace before beginning the practical portion of the PADI open water dive course.
The e-learning structure is as follows:
It consists of five chapters; at the end of each chapter is a multiple-choice exam. The pass rate is 75%, and until you have passed, you can’t move forward to the next chapter.
You simply keep returning to the start of each chapter until you have passed 75%. Chapter five is the final exam. The exam is a multiple-choice test that covers five chapters. If you do not achieve a pass rate of at least 75%, please feel free to try again.
After the exam there are additional chapters to learn about using a dive computer and understanding deeper the RDP (recreational dive planner).
Throughout the chapters, there are videos to watch for a more profound understanding of each chapter. For instance, you can watch videos on underwater sign language and natural buoyancy.

Day 2: Diving from the boat
This part of the PADI Open Water dive course is where most feel anxious. Although the course is not physically demanding, some participants may experience anxiety or fear in the water, which is normal. Instructors are there to assist, showing patience and encouragement throughout your dives and on board.
Before training begins, we will show you around the boat so you can familiarise yourself and unwind with coffee.
Being physically and mentally prepared for the course can contribute to a smoother and more enjoyable experience, so relax and prepare mentally.
The PADI Open Water Dive course stresses safety, with diving instructors always ensuring that their students are comfortable, confident in their abilities, and mentally prepared for their next journey.
- Your instructor will go over setting up your equipment.
- You will set up your equipment under supervision.
- Carry out safety checks on diving equipment.
- Carry out buddy checks on diving equipment.
Your dive instructor explains the activities you will have to practice, the depths, and what marine life you can expect to see.
Another skill your dive instructor will teach you is getting from the boat to the water. There are a few different ways of entering the water, and your choice depends on the boat you’re exiting.
Most diving will be from a boat or speedboat; therefore, the STRIDE will be used.
Once in the water, your dive instructor will start the controlled descent.
Days 2 and 3: Practice the skills needed for open-water diving.
The 2-day, 4-dive period will cover all the skills from Day 1 in the pool. At the end of each dive, the dive instructor will provide feedback and go over various tasks to ensure that you’re fully aware of what you did incorrectly and how to improve.
The final step on the journey to learn scuba diving with PADI Open Water.
Celebrate and welcome to your amazing new adventure of scuba diving around southern Thailand and the globe!

Why scuba diving?
Not everyone can scuba dive, but those who love snorkeling and are fascinated by the ocean should.
For me, being up close and personal—if you like—with marine life was my desire, and I certainly got up close and personal on many occasions!
Scuba diving is also a fantastic social network; meet new friends around the globe and chat for hours about dives and the dive of the day.
