DECO 50
Getting the ‘thumbs up' sign is probably the worst signal any diver can receive since it signifies that the dive has ended. Extending time, and sometimes depth, in water is probably every divers desire. The thrill of pushing the envelope and becoming an explorer is what drives many to become divers, and the Deco 50 course forms the basis and essential skills and knowledge needed to become an explorer.
Deco 50 has been written with the new technical diver in mind. This means that divers wanting to participate in technical open circuit programs and who are certified in Deep 40, Master Rescue and Nitrox may bypass the Deco 40 program.
The course has modern, graphic rich manuals which explore and introduce the most modern information and techniques. A modern skill set places emphasis on managing skill mastery while neutrally buoyant. The skills themselves have been up as well with desire being that RAID divers will use a similar equipment configuration and perform the skills in a similar fashion.
The program overview is as follows:
- Dive to a maximum depth of 50 metres/165 feet.
- Use any optional combination of air, nitrox, trimix and / or oxygen.
- The END / EAD for trimix must not exceed 30metres / 100 feet.
- Complete a maximum of 30 minutes accelerated decompression.
- Divers may only utilise a single decompression gas.
- Divers may use up to 100% oxygen for accelerated decompression.
- Divers must use a multi-gas switch computer.
- Bottom or back gas maximum PO2 is 1.4 and a maximum of 1.6 for accelerated decompression gas.
- Certified to use air, nitrox, oxygen and trimix with a maximum END/EAD of maximum 30 metres/100 feet.
Objective | Decompression diving brings with it a new dimension. In the case of the Deco 50 course, depth is not increased but bottom time certainly |

Reason for Learning | The Deco 50 course builds upon the knowledge and skills from Deco 40. Divers will learn to carry and utilize an additional stage/deco cylinder as well as normoxic trimix to depths of 50 m/200 ft. Advanced dive planning techniques, multiple stage handling and unlimited decompression times are the highlights of this course using normoxic trimix and oxygen mixtures up to 80 percent o2. |
