I. Course Description
This outline is generic and designed to work with all SCR, mechanical and electronic closed circuit re-breathers PSAI have enabled Instructors to teach. A re-breather manufacturer specific requirement on depth, gas or absorbent canister duration will always take precedence if within the standard set out below.
II. Course Objectives
The PSAI Advanced Re-breather Diver Course student will be able to demonstrate proper re-breather care and maintenance, both pre and post dive. The student will also demonstrate proficiency in the skills outlined in Section X, Skill Requirements, of this outline.
lll. Course Qualifications
Apply the knowledge and skills outlined in this standard to plan and conduct decompression dives in environments and conditions similar to their training, when properly equipped and accompanied by another certified diver.
IV. Prerequisites for Course Entry
- The student shall be at least 18 years old at time of course entry.
- The student shall have graduated from a minimum of an internationally recognized PSAI Advanced Nitrox or equivalent advanced Nitrox and decompression skills course. If the student is coming from a PSAI Re-breather Non Decompression background the content is detailed within this standard.
C. Prior Dive Experience
D. Special Notes
- This course may be taught in conjunction with PSAI Advanced Nitrox Diving course at the discretion of the PSAI Instructor where no prior decompression diving qualification is held. This is to enable a diver to make a choice between safety stop and required decompression diving.
V. Course Minimums and Standards
A. Classroom Hour
- A minimum of 12 classroom and practical demonstration (equipment assembly/disassembly) hours are required for the PSAI Advanced Re-breather Diver course.
B. Confined Water Dives
- The first 120 minutes diving using a re-breather must be conducted in a swimming pool or confined open water with swimming pool like conditions. (See general Standards for confined water specifications).
C. Open Water Dives
- A minimum of four (4) simulated decompression dives and two (2) decompression dives of a total minimum of 360 minutes duration are required for the PSAI Advanced Re-breather Diver course, unless the PSAI instructor makes a written exception on the diver’s record based on diving background and experience* (See point D) with other re-breathers or training. Where there is a manufacturer requirement for increased diving time then this will take precedence. Maximum depth in all cases will be 48 meters (157 feet).
D. *PSAI Qualified Sport Re-breather Divers
- A Re-breather Non Decompression Diver must sit in on Advanced Nitrox or decompression planning and equipment configuration presentations and gain Advanced Nitrox qualification. A Sport Re-breather Diver needs to undertake all the skills satisfactorily from Section IX Skill Requirements Section C. Dives to achieve points 13 &14 are to be standalone dives and one dive must be to within 3 meters (10 feet) of the qualification depth sought. All other highlighted skills must be demonstrated throughout any decompression dives on the course.
VI. Course Instructional Materials Requirements
A. All students will use the appropriate PSAI Advanced Re-breather Diver manual. Provided by us.
B. All students will also use the manufacturers recommended documents or instruction manual for the chosen re-breather.
C. PSAI Re-breather instructors will use this Standard and the PSAI Re-breather Diver Course Guide, as a minimum. A PowerPoint presentation is also available.
D. PSAI also has a teaching slate and a set of scenario slates for this course.
VII. Course Equipment Requirements
A. Each student is to have access to and full use of a re-breather for the duration of the course. PSAI do not recommend sharing re-breathers.
B. Exposure equipment suitable for use in the environment where the course is conducted.

A. Land Based - A PSAI Advanced Re-breather Diver student shall:
- Plan re-breather dives based on specified gases, setpoint and dive depths.
- Properly pack and repack (a minimum of three  times) an absorbent canister using granular fill absorbent material. If pre-packed absorbent canisters such as “Extend-Air” are available, ensure these are fitted and used once (1) also.
- Properly assemble and test a re-breather prior to every dive. A manufacturer checklist must be used where supplied. If one does not exist the Instructor will provide a PSAI checklist suitable for the model of re-breather.
- Properly conduct pre-dive and pre-breathe checks prior to all dives.
- Properly conduct an oxygen fuel cell swap out, only where permissible (manufacturer stipulation).
- Properly conduct a battery swap out or re-charge.
- Where additional electronics are fitted - Demonstrate competence with use of additional PC linked software to up-load set-up information, monitor and log dive parameters and download completed dives on the course.
B. Confined Water - A PSAI Advanced Re-breather Diver student shall undertake skills required to enable the correct continued use of a re-breather:
- Perform buoyancy control drills.
- Perform mouthpiece & loop water clearance drills.
- Perform bailout switch drills.
- Perform gas switch skills where required by equipment.
- Perform correct handset monitoring and setpoint switching.
- Maintain an elevated setpoint manually where possible (equipment limitations will dictate use of this skill).
- Perform oxygen cell verification by flushing with oxygen at 6 meters (18 feet) .or shallower and check against depth. Record reading and depth. (This skill is repeated in the open water section with diluent addition only.)
- Perform a diluent flush to simulate increased oxygen emergency. This is also referred to as going “Open Loop”.
- Perform a successful loop flood and clearance only if the equipment is 9.designed to tolerate such action. (3 meters/10 feet).
C. Open Water - A PSAI Advanced Re-breather Diver student shall:
- Conduct the dive according to their plan, as approved by the PSAI instructor.
- Monitor gas pressures and surface with an acceptable safe margin.
- Not to exceed any Maximum Operating Depth or Oxygen exposure limitations.
- Correct setpoint choice.
- Perform buoyancy control drills both at depth greater than 30 meters (100 6.feet) and in shallow water 6-10 meters (20-33 feet).
- Properly execute a recovery from a system failure to bailout whilst stationary on two (2) separate dives.
- Properly execute a recovery from a system failure to bailout whilst hovering on two (2) separate dives.
- Perform a diluent flush/open loop successfully on each dive.
- Perform oxygen cell verification by flushing with diluent at 15 meters (50 feet) or deeper and check against depth. You must record reading and depth. Perform this skill at 3 differing depths.
- Perform gas switch skills where required by equipment on two (2) separate dives.
- Manually maintain an elevated setpoint (maximum 1.4 bar) for 20 minutes minimum during the bottom phase of a dive no deeper than 30 meters (100 feet). Discuss timing between and duration of oxygen addition manual inject with instructor both before and after the skill is successfully undertaken. Compare your findings. (Some modern re-breathers will not allow you to inject oxygen manually and this skill will be regarded as not required.)
- Simulate a recovery from a stuck ‘open’ solenoid simulating the last 10 minutes of a dive including ascent and safety stop.
- Perform a simulated and controlled rescue of a fellow re-breather diver from a minimum of 20 meters (65 feet) – Control the rescue and stop at 7 meters (23 feet). Demonstrate contact, control and observation throughout the drill.

- Conduct accurate safety stops on all decompression dives.
- Demonstrate sound surface rescue tow technique of a fellow re-breather diver to a nominated point of safety.
X. Course Completion Performance Requirements
To be awarded the Professional Scuba Association International’s Advanced Re-breather Diver certification, the student must:
A. Attend all required academic sessions.
B. Successfully master all academic and in-water skills.
C. Correctly set-up all electronic monitoring parameters fitted to a re-breather.
D. Correctly perform all dry land based checks and maintenance.
E. Complete the PSAI Advanced Re-breather Diver written examination with a score of at least 80%. All questions shall be correctly answered or remediated and explained.
F. Conduct the open water dives with appropriate skill and attention to all dive parameters.
G. Conduct correct post-dive cleaning and maintenance procedures.
H. Correctly plan, execute, and log the required dives.
The PSAI instructor is responsible for ensuring that the Advanced Re-breather Diver student has demonstrated the appropriate respect and understanding for diving with a re-breather. If the student fails to maintain proper depth control, gas management or time awareness, etc., the instructor may require additional training to take place prior to certification.
Note: Depth Qualification following successful completion of this course is commensurate with the students own diving experience and choice of re-breather. These PSAI parameters are offered as maximum depths:
If PSAI Advanced Nitrox certificate is taught as part of the course the student will be assessed as diving to a maximum of 45 meters (150 feet) and able to undertake correct decompression diving skills and stops. The PSAI Advanced Nitrox certificate must also be issued. If previous formal experience shows training in decompression skills diving then the additional Advanced Nitrox qualification need not be issued but 45 meters will still remain the maximum depth permissible.
Where a student wishes to undertake non-decompression diving on a re-breather following this standard, the maximum depth qualification will be maximum 30 meters (130 feet). The qualification will be Re-breather Diver, not Advanced Re-breather Diver.
All levels of PSAI Rebreather certification cards are Brand & Model specific. The Brand and Model the student was trained on will be listed on the certification card. No “generic” rebreather certification cards will be issued by PSAI at any level.
