Divemaster Pre-Requisites and Duties

This page is the quick reference for what you need before starting a Divemaster course, and what you'll be authorised to do once you've completed it. Both lists come straight from PADI's Instructor Manual — the same standards every dive centre and course director must follow, regardless of where in the world you train.

The prerequisites tell you what to arrange before arrival. The authorisations tell you what your PADI Divemaster card lets you actually do at a dive centre. We've added a few practical notes alongside each — what we cover for you, what we don't, and what's worth knowing before you book.

Five prerequisites. Fourteen authorisations. One PADI standard.

Divemaster Course Prerequisites

Five PADI requirements. All must be in place before formal Divemaster training begins.

  1. PADI Advanced Open Water Diver and PADI Rescue Diver certifications — or qualifying equivalents from another agency (SSI, NAUI, BSAC, CMAS and similar are all accepted). If you don't yet hold these, our packages can include the courses you need, sequenced so you arrive at the start of your Divemaster training fully certified and dive-ready.
  2. 18 years of age or older. This is a hard PADI standard with no exceptions. If you turn 18 during your visit, you can complete prerequisite courses up to that day and start formal Divemaster training on your birthday.
  3. Medical clearance signed by a physician within the previous 12 months. Most candidates arrive with this already done. If yours has lapsed or you don't have one, there's a recommended physician five minutes' walk from the shop in West End who can sign you off in around thirty minutes.
  4. 40 logged dives to begin formal Divemaster training, and 60 by certification. You do not need either figure to arrive. Candidates who start below 40 spend those first days getting in the water and logging dives as the main activity, alongside confined-water skill practice and land-based duties. Work on the PADI Divemaster performance requirements — and sign-off on any of them — begins once 40 dives are logged. Diving starts the day you arrive and the dives that get you to 40 cost you nothing extra.
  5. Emergency First Response Primary and Secondary Care certification within the last 24 months. If your EFR has lapsed, we run the refresher on-island; budget half a day for it.

Divemaster Authorisations

Once certified, an active-status PADI Divemaster is authorised to do all of the following. The list below is the verbatim PADI standard. Most of these are things you'll have rehearsed live during your Divemaster Internship, not just learned from a manual.

  1. Supervise both training and non-training-related activities by planning, organising, and directing dives.
  2. Assist an instructor during confined and open water training.
  3. Guide Open Water Diver course students on the tour portion of Open Water Dives 2, 3, and 4 at a 2:1 ratio, under the instructor's indirect supervision.
  4. Accompany Open Water Diver students under the instructor's indirect supervision during surface swims to and from the entry/exit point and during navigational exercises, and supervise remaining students when the instructor conducts a skill.
  5. Accompany student divers during Adventure Dives or specialty course dives under the instructor's indirect supervision.
  6. Teach and certify PADI Skin Divers independently. This includes conducting the PADI Seal Team AquaMission: Skin Diver Specialist.
  7. Conduct the Discover Snorkeling program.
  8. Conduct subsequent dives under an instructor's indirect supervision for Discover Scuba Diving participants at a 2:1 ratio, after participants have satisfactorily completed the first dive with an instructor.
  9. Conduct the Discover Local Diving experience.
  10. Conduct the ReActivate program for certified divers.
  11. Conduct the skin diving skills segment of the Open Water Diver course during confined water dive 2, 3, 4, or 5.
  12. If qualified as a Discover Scuba Diving Leader, independently conduct Discover Scuba Diving in a pool or in confined open water.
  13. Accompany certified PADI Scuba Divers on subsequent dives.
  14. After completing the corresponding instructor training, conduct:
    1. Digital Underwater Photographer specialty courses under the direction of a PADI Instructor.
    2. Emergency Oxygen Provider courses.

The list above is wider than most candidates expect. The PADI Divemaster isn't just a guide certification — it's the foundation for everything that comes next, including the Instructor Development Course.

By the book. Built in real conditions.

Why earn your Divemaster at Go Pro Caribbean

Every PADI Divemaster, anywhere in the world, has to meet exactly the same standards. The list above is identical in Cairns, Cozumel, Phuket, and Roatan. What changes between training centres is the operator — and how they choose to deliver the work behind each line of the standard.

At Go Pro Caribbean the Divemaster Internship is exactly that — a working role rather than a fixed timetable. From your first day you're on the boat with paying customers, watching real briefings, real entries, real ascents — alongside full-time PADI instructors who run a busy dive centre every day. Six weeks is the duration we recommend, and it is a full working week while you are with us — around 45 hours. By the time you're ticking off the formal skills, you've already spent weeks watching how each of the fourteen authorisations actually plays out in practice.

We're deliberately small. Class sizes stay tight, every candidate gets direct contact with Will Welbourn, and most Divemaster graduates stay on for their PADI Instructor Course at the end of their Divemaster Internship. Will is a PADI Platinum Course Director who has certified more than 500 instructors since 2008. Earning your Divemaster here means you arrive at instructor training already fit, dive-ready, and comfortable in a working dive operation.

What the Divemaster course costs

Entering with a PADI Rescue Diver certification. Go Pro Caribbean charges for training and materials; PADI fees are paid directly to PADI and are the same wherever you train.

Go Pro Caribbean — Divemaster training and materials Rescue Diver entry. Unlimited diving throughout. $1,050
PADI Divemaster application fee — required Paid directly to PADI, not to us. Subject to change by PADI without notice. $168
All-in, Rescue Diver entry $1,218

Entering at Open Water, Advanced Open Water or complete-beginner level means more courses along the way, so those pathways cost more. The full grid is on the Divemaster Course Packages page. Working to a shorter timescale than six weeks? Message Will Welbourn before you book and he'll tell you honestly what is workable.

Frequently asked questions about the PADI Divemaster

What are the prerequisites for the PADI Divemaster Course?

PADI Advanced Open Water Diver and PADI Rescue Diver certifications (or qualifying equivalents from another agency), 18 years of age or older, medical clearance signed by a physician within the last 12 months, 40 logged dives to begin formal Divemaster training and 60 by certification, and a current Emergency First Response Primary and Secondary Care certification within the last 24 months.

Do I need 40 logged dives before I can start the Divemaster course?

No — you can begin your Divemaster Internship with fewer than 40 dives. Until you reach 40, the programme is built around getting in the water and logging dives as the main activity, alongside confined-water skill practice and land-based duties. Work on the PADI Divemaster performance requirements, and sign-off on any of them, begins once 40 dives are logged. PADI requires 60 logged dives by certification, and the average trainee here logs between 60 and 100.

How old do I need to be to become a PADI Divemaster?

18 years of age or older — no exceptions. PADI requires every Divemaster candidate to be 18+ at the point of certification. If you turn 18 during your stay, you can complete prerequisite courses up to that date and start formal Divemaster training on your birthday.

What is a PADI Divemaster authorised to do?

An active-status PADI Divemaster can supervise certified divers, assist a PADI Instructor during training, guide Open Water students on the tour portion of dives 2 to 4, conduct the ReActivate refresher programme, lead Discover Local Diving and Discover Snorkeling, and teach Skin Diver courses independently. The full list runs to fourteen separate authorisations, set out in the duties section above.

Do I need a medical certificate to start the Divemaster course?

Yes. PADI requires a medical clearance signed by a physician within the previous 12 months before any Divemaster training begins. If you don't have one on arrival, a recommended physician five minutes' walk from our shop in West End can complete the assessment in around thirty minutes.

What is the difference between a PADI Divemaster and a PADI Instructor?

A Divemaster is the first professional-level PADI certification — authorised to assist an instructor and supervise certified divers. A PADI Instructor is the next step up — authorised to teach courses and certify divers independently. Most Go Pro Caribbean Divemasters continue with the Instructor Development Course at the end of their Divemaster Internship.

How long does it take to complete the PADI Divemaster course?

Six weeks is the recommended duration, and there is no upper limit. Candidates who wish to take eight, ten, or twelve weeks are welcome. If you need to finish in less time than that, talk to us before you book and we will tell you honestly what is workable. Expect a full working week while you are with us — around 45 hours. Diving is unlimited throughout, and the average trainee at Go Pro Caribbean logs between 60 and 100 dives before qualifying.

How much does the PADI Divemaster course cost at Go Pro Caribbean?

Training and materials start at $1,050 for candidates entering with a PADI Rescue Diver certification. The PADI Divemaster application fee of $168 is paid directly to PADI and is required, bringing the all-in figure to $1,218 on that entry point. Candidates entering at Open Water, Advanced Open Water or complete-beginner level take more courses along the way and pay more — the full grid is on the Divemaster Course Packages page.
