PADI Divemaster Course

The PADI Divemaster course is the beginning of your professional career in the world of diving. It is a great step in a diver´s life, which will make you see diving differently. With the PADI Divemaster course, you will become a diving professional, a leader, a competent and reliable person. Able to organize and direct diving excursions and other underwater activities in complete safety.

At the knowledge level, the Divemaster course will probably be the most important in your professional career. As it is the course in which you will learn all the theory and techniques necessary to become a professional, it´s the base on which the rest will be supported of courses, such as, for example, the Instructor course, which you will surely want to opt for once you obtain the Divemaster certification. This is why this course is so important, because, without a good foundation as a Divemaster, the IDC instructor course will be a lot more complicated.

A question that you should ask yourself before starting the Divemaster course is: Where do I want to do the Divemaster course? There are endless options to choose from, the dive centers work differently when it comes to teaching and working. That is why you should choose a dive center that suits you, your personality, where you feel comfortable with her philosophy, and with her way of teaching and working.

We will assign you a mentor, who will be the person in charge of your Divemaster training and will guide you throughout the PADI Divemaster course. Your mentor will be your main support and reference, but you will accompany and work with absolutely all the Hidden Depths Diving staff members so that you can have several references, and learn the best of each one of us. Always placing special emphasis on conservation, respect for the environment, and safety in diving.

All this with a relaxed and professional atmosphere. Come and meet us, we have the best atmosphere to get your PADI Divemaster license in Koh Lanta. You will love it!

PADI Divemaster course structure

The PADI Divemaster course consists of 4 blocks, which you will intersperse throughout your training:

Diving theory: Theory is one of the most important building blocks of the PADI Divemaster course. You will learn and master the necessary concepts of diving in a professional way. We recommend a previous reading of all the diving manuals that you have from previous courses, such as Open Water, Advanced, or Rescue.

Water Stamina: You will have to demonstrate your skills in the water by performing various swimming exercises. A challenge that every divemaster must face.

Skill Circuit: You will practice and learn how to teach all the diving skills of the PADI Open Water course. Repetition is the secret to mastering underwater demonstrations and to teaching them correctly.

Guiding: You will become a professional dive guide. With the help and direct supervision of a PADI instructor, you will learn and develop the necessary skills to guide certified divers. We will place special emphasis on the preparation before the dive, the safety of the group, and of course, the conservation of the environment.

Medical requirements for scuba diving

It is mandatory to pass a simple medical questionnaire before taking any PADI diving course. It is a simple questionnaire on different pathologies in which it is supposed that you answer “no” to all the questions to be eligible and start the diving course.

In case you answer “yes” to any of the questions, it does not mean at all that you are not suitable to dive, it simply means that you need to consult a qualified doctor and that he/she certifies in writing that you are suitable for diving.

You can bring this certificate with you, or we can do it in Koh Lanta for an approximate price of 600 Baht. If you want, we can help you manage the reservation with the doctor, and it will not take you more than 10 minutes to have your certificate.

If you want to go ahead, or want to take a look at the medical form, here are the links to the PADI medical form in the main languages:  English SpanishFrenchGermanItalianChinese (simplified).
