PADI Semi Closed Rebreather Speciality


Drager Atlantis/Dolphin Semi Closed Rebreather

This is Technically a PADI course, but we like our technical instructors to teach the course. With their experience working in the recompression chamber they can

teach you the benefits of breathing enriched air at depth and what problems that might accur when too much co2 is in your breathing loop.

This is an ancient science that still to this day is far superior to any open circuit systems around! With no bubbles and sound created by "Darth Vader" open circuit regulators, this is a must for anyone who wants to be at one with the marine life, especially if you want to photograph the underwater world.

This course is a must during high season, where you can dive the Similan Islands with Scuba Cat Diving, Phuket, Thailand during your course and have the option to fun dive with the unit after you are certified.

You need to be a Nitrox diver before you can start this course. We also provide Nitrox courses.

This has many unique advantages:

  • No noisy valve, no bubble noise
  • Previously shy marine animals will allow a much closer look
  • Your breathing gas is continuously warm and moist
  • Reduced usage of breathing gases since 90% of the gases are recycled
  • Plus all the advantages of diving with Nitrox.

As one of the most fun and informative courses on offer you will learn how to fully set up and breakdown the unit along with a 1/2 day theory session on understanding rebreather diving along with three training dives.
