Deco 40m/130ft


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 RAID DECO 40 program forms a bridge between recreational and technical diving. The problem with technical diving is that it has marketed and positioned itself as unattainable for the average diver. Divers are led to believe they must have superhuman strength and mental agility to participate in a technical diving program. Of course, here at RAID we believe this is simply not the case, but believing and acting are two totally different things.

The Deco 40 program is aimed squarely at the recreational market and not at the technical market. The program is ideally completed using modified recreational equipment. Deco 50 Instructors may teach the Deco 40 program using twinsets, and Deco 40 instructors certified as Sidemount Instructors may teach the program in sidemount configuration. The Deco 40 makes an ideal entry-level decompression program, but it must be noted that it has been created with the recreational diver in mind.

The Deco 40 program awards divers multiple certifications in one. The program overview is as follows:

There are 6 manuals and quizzes.

a) Equipment

b) Physics

c) Physiology

d) Management

e) Confined Water

f) Open Water

Divers MUST participate in at least one confined water skill session and 5 open water dives.

◦ These dives may credit towards the Deco 50 program.



We have taken a new approach to the development of all our new technical manuals where the bulk of the information is contained in the entry level programs, and then as divers progress, they are presented with only the information needed to make that progression. 

Therefore, the Deco 40 and 50 manuals vary only slightly since divers can enter at either the Deco 40 or 50 level, depending upon their experience, certification level and personal desire.
