EXTENDED DECOMPRESSION

A BRIDGE TO DEPTH WITHOUT HELIUM

In many locations around the world, helium gas, the accepted relief for divers from the rigours of inert gas narcosis, is unavailable. Yet dives to 40 or 50 or even 55 metres are possible in some conditions. This RAID course has been designed for those circumstances. This course is open to sidemount and twinset divers using up to four stage cylinders containing custom nitrox blends and air.

TECHNICAL OC PATHWAY

REASONS TO TAKE THIS COURSE

There are deep wrecks and other types of dive site around the world in places where access to helium renders trimix diving impractical. This RAID Extended Decompression course is available to divers who wish to venture below 40 metres using compressed air as a breathing gas to a maximum depth of 55 metres. This program provides the training and background knowledge, and equipment selection and management techniques that help make such dives possible.

SKILLS (WHAT YOU’LL LEARN)

On this course, students will learn about the history and hazards of deep diving. Other topics covered include hypoxia and oxygen toxicity, inert gas narcosis and the contributions of other factors to narcotic effects, nitrogen uptake and decompression stress, among others.

OUTCOME

Graduates from this program will have a solid understanding of deep diving without the aid of trimix and be drilled in complex equipment management.
