Inspiration Re-breather Diver - 6 days

This is the entry-level certification course for recreational divers wishing to utilize the Inspiration Closed Circuit Rebreather. The objectives of the course is to train recreational divers in the benefits, hazards and proper procedures for rebreather diving on the Inspiration CCR and to develop basic rebreather diving skills appropriate to diving within recreational depth limits of 30 msw using an air diluents with no decompression.

 

We can also supply CCR units from new cheaper than direct sale and parts for all the Ambient Pressure Units through our trade department.

 

I. Course Description

The Professional Scuba Association International’s (PSAI) Re-breather Non Decompression Diver course is designed for those divers who wish to utilize either enriched air (Nitrox) in a Semi Closed Circuit Re-breather or oxygen concentrations up to and including 100% (+/- 1% by analysis) in a Closed Circuit Re-breather during their sport diving activities. The training and qualification depth is limited by the choice of equipment and in all cases to a maximum of 30 meters (100 feet). This course and qualification does not include decompression diving.

 

This PSAI standard is designed to encompass many sport focused re-breathers in a generic format and is not a depth critical course. Depth qualification printed on the student certification is dictated by the student’s practical ability based on their recreational qualification, the chosen equipment and manufacturer’s guidelines for that equipment & the Instructor’s assessment of the student’s capability observed and discussed upon completion of the course. . Should the diver be qualified beyond 30m (100’) it may be more advantageous to consider the Advanced CCR level.

 

II. Course Objectives

The PSAI Re-breather Non Decompression 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.

 

Course Qualifications

Apply the knowledge and skills outlined in this standard to plan and conduct non-decompression sport dives in environments and conditions similar to their training, when properly equipped and accompanied by another certified diver.

 

IV. Prerequisites for Course Entry

A. Age

  • The student shall be at least 18 years old at time of course entry.

B. Certification

  • The student shall have graduated from a minimum of an internationally recognized Open Water course or undertake an open water course where the re-breather is the primary scuba unit of choice and all skill conducted using the re-breather. A PSAI, PADI or similarly recognized Nitrox Diver qualification is also required.

C. Prior Dive Experience

  • No dives other than those required for Open Water and Nitrox Diver certification are required for entry into the PSAI Air Re-breather Non Decompression Diver course.

 

V. Course Minimums and Standards

A. Classroom Hours

  • A minimum of eight (8) classroom and practical demonstration (equipment assembly/disassembly) hours are required for the PSAI Re-breather Non Decompression Diver course.

B. Confined Water Dives

  • The first dive using a re-breather must be conducted in confined water. Progression to open water is to be undertaken when the student demonstrates control and ability indicating an improving awareness of re-breather monitoring.

C. Open Water Dives

  • Five (5) further dives are required for the PSAI Re-breather Non Decompression Diver course, unless the PSAI instructor makes a written exception on the diver’s record based on diving background and prior experience with other re-breathers. All dives are to be conducted with a suitable bailout carried by the student. No dives are to require decompression to complete them. Safety stops of 1-3 minutes at 6 meters (20 feet) are not viewed as planned decompression stops. The qualification depth printed on the certification will be within 3 meters (10 feet) of the depth achieved on the course but will not exceed 30 meters (100’).

 

VI. Course Instructional Materials Requirements

A. All students will use the PSAI Re-breather Non Decompression Diver manual and PSAI EAD Tables for planning. Provided by us.

B. All students will use the manufacturers recommended documents or instruction manual for the chosen re-breather. Provided by us.

C. PSAI Non Decompression Re-breather Instructors will use this Standard, PowerPoint presentation and the PSAI Re-breather Non Decompression Diver Course Guide, as a minimum. An Instructor guide is also required.

 

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.

C. Oxygen Analyzer equipped with flow restrictor assembly supplied by the Instructor. An additional oxygen analyzer that is hand held to the face of the valve may also be demonstrated, but only as an adjunct. The student must be familiar with the enclosed technique as a minimum.

D. Equipment suitable to conduct flow rate, full leak testing and absorbent changes throughout the course.

E. Independent bailout equipment. This must be supplied by the Instructor where the student has no prior experience of setup.

 

Vlll. Curriculum Requirements
