TDI Divemaster


The TDI Divemaster Course is the first professional level certification in the TDI leadership levels. During this course you will be challenged and learn what it is like to work with divers as they begin or continue their technical diving experiences. You will learn how to manage divers, work as land or boat support, and conduct enjoyable dives. Dive physics, physiology, how conduct pre-dive briefing, how to assist technical instructors as well as how to be a professional TDI Divemaster is all part of the course. Your skills will be refined to demonstration quality and your knowledge increased to that of a technical diving professional.


Who this course is for:

  • SDI Divemaster who are certified technical divers and want to assist with TDI Diver Courses and lead technical dives at the level they are certified to dive

Course Duration:

Courses should not be treated as a race or something that can be skipped through quickly. Please remember training does not guarantee certification, we need to ensure you fully understand the training and will be a safe diver on certification. We follow a loved one clause that when certified we would be happy you could safely dive with one of our loved ones.

  • The e-learning and academic portion of this course should be completed before starting in water training and exercises. The duration of this piece is dependant on your availability. During this time our instructors are on hand to assist with questions or any element you may struggle with.
  • For many courses the swimming pool or confined water sessions give us time to practice and carry out skills in a controlled environment. We do not fix specific number of pool sessions as it is dependant on your comfort level with skills before moving to open water.
  • The open water element is again determined more by time in water rather than number of dives. We prefer longer dives building experience rather than quick short 20 minute 'dips'.
We will strive to meet your timelines and requirements where possible and will always be dependant on student availability to attend sessions.
