SSI Divemaster

Master Your Skills, Start Your Career in Diving

The SSI Divemaster is the most popular professional level certification. In addition to guiding certified divers, Divemasters get to assist on courses, work on dive vessels and resorts, and teach snorkelling courses. From Dive Guide you get to Divemaster level by taking the Science of Diving course, which expands your understanding on the broad subject of diving theory.

This is an internship-style course, where you participate in the daily life of a busy dive shop. The course includes skill development both in confined and open water to the level that you can demonstrate them to others. Your training will also cover the safety aspects of being a dive leader, and you will learn how to best take care of your customers in a variety of conditions. You will work with our instructors and to learn from their teaching styles and briefings.

Equipment and course requirements

Depending on your starting level, we will customise the course to your needs. In order to be certified as a Divemaster, you need to have completed Stress & Rescue, hold a current first aid certificate with the ability to administer emergency oxygen, have at least 50 logged dives, and completed the Dive Guide programme.

We recommend to reserve anywhere between 4 and 8 weeks for this programme in order to have plenty of time to complete all requirements and to gain experience.

At this level you should have at least the following equipment of your own:
  • Dive computer
  • Compass
  • SMB and reel
  • Whistle
  • DiverĀ“s tool (knife or a cutting tool)
  • Mask, snorkel and fins
We offer a 10% discount to all our professional level students, so if in doubt, you can get your equipment once you get to the island.
