Do you have a deep and abiding passion for diving?

Is every moment on the surface merely an extended surface interval?

If so, you should consider doing what you love for a living: become a PADI Professional.


Do you have a deep and abiding passion for diving? Or, do you merely love it with all of your heart? If so, you should consider doing what you love for a living: become a PADI Divemaster.

When you join the tribe by becoming a PADI Divemaster, you align yourself with the largest and most respected dive tribe in the world – that of PADI Professionals. These are PADI Divemasters and Instructors sharing a passion for diving and an active concern for the health of the world’s underwater habitats.

What will you learn?
The PADI Divemaster course is the first professional level within the PADI system of diver education. Your own dive skills will be improved to demonstration standard and your dive theory knowledge will be raised higher, allowing you to answer any of the questions you will often be asked by trainee divers.

The interaction with your PADI Instructor will be different to your previous training courses. We will involve you in decision making, as well as dive planning and course briefings and debriefing with students. This allows you to see how divers are trained, and apply these techniques to your future students. The goal of the Divemaster course is to improve your skills, and teach you how to effectively work with students to create the best possible divers.

The Divemaster course allows you to work as a training assistant on PADI courses and programs, supervise certified divers during pleasure diving experiences, and conduct some PADI programs independently.

Becoming a PADI Divemaster consists of the following segments: knowledge development, practical applications and the Divemaster final exams. The self study portion of the course covers nine topics that prepare you for the practical sessions needed to complete the Divemaster course.

What are the prerequisites for PADI Divemaster Course?
Prior to enrolling in PADI Divemaster, you must be at least 18 years old, have a current medical attesting to your diving fitness signed by a physician within the previous 12 months, and be a certified PADI Advanced Open Water Diver and PADI Rescue or hold qualifying certifications from another dive training organisation. You must also have completed an Emergency First Response (EFR) Primary and Secondary Care course within the last 24 months.

How does it work?
After enrolling, we will sit and go through paperwork and make sure you understand all the different aspects involved in the course. We run the Divemaster course on an ongoing basis, allowing you to fit your training around other commitments you may already have. This lets you move through the program efficiently and at your own pace, and work with a variety of students and instructors to gain knowledge from each one.

What Scuba kit will you use?
As a Divemaster you are expected to have all your own scuba kit, including dry suit and dive computer. Kit hire can be included in the course, however at this level an investment in your own kit will really help you in the water. There are other required materials such as an RDP table and eRDPML which are used in your theory and exams. These can be ordered if you don’t have them from your previous PADI courses.

Any additional costs? 
Upon certification there is a separate application fee paid directly to PADI. The current application fee for a Divemaster course is £72.50 plus VAT, and £30 plus VAT for the Discover Scuba Diver Leader rating. To work in the UK as a diving professional you will need an annual HSE medical. The initial medical costs approximately £120 and each subsequent annual medical is around £90. You will also need your own professional liability diving insurance. If you have any questions about any of these please get in contact and we can discuss with you.

Hidden Depths Scuba School run two weekly pool dives around Bristol, primarily for scuba training, but also open to club members.


See the excitement on students’ faces when you take them for their first breaths underwater on their Discover Scuba Dive! Once you’re qualified as a PADI Divemaster you can work closely with our experienced PADI Instructors to develop your teaching skills with entry level divers. Upon completion of this programme you will be qualified to take Discover Scuba Divers on their first dives in a pool or confined open water.

We will work closely with you to run five Discover Scuba Diving sessions. After this, and a Discover Scuba Diver leader exam, you will be qualified to take this programme independently, which is a great plus if you plan to work here in the UK or abroad as a Divemaster. A truly rewarding extra for your Divemaster Course!


As a PADI Assistant Instructor, you not only gain additional experience as a PADI Professional, but you also expand your knowledge of the PADI system of diver education. You can act as an instructional scuba assistant and assume limited teaching responsibilities. It’s a great way to gain experience in order to become a full Open Water Scuba Instructor!

Our Assistant Instructor courses are run through Dive Beyond, based in Portland, who are an IDC dive centre. The PADI Assistant Instructor course is the first portion of the PADI Instructor Development Course (IDC) and when followed by the Open Water Scuba Instructor course (OWSI) and successful performance at the Instructor Examination (IE), leads to certification as a PADI Open Water Scuba Instructor!
