Deco 50

From: $1,500.00

Our Deco 50 program highlights a different approach to learning staged decompression diving, and has been written with the new technical diver in mind, so you benefit from a training program designed from scratch using the most up-to-date techniques and technology.


Unique to RAID, 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 a modern skill set placing 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 Manuals Are Also “User Friendly” For Sidemount Divers
