JJ-CCR AIR DILUENT DECOMPRESSION PROCEDURES DETAILS
Rebreathers are fun all of the time, but they really shine on deep and decompression dives. This JJ-CCR Air Diluent Decompression Procedures Course is a logical next step after gaining experience on your JJ-CCR. For divers with decompression procedures certification on other units, it’s possible to do a unit-specific upgrade for the JJ-CCR.
WHERE WILL I DIVE DURING THE JJ-CCR AIR DILUENT DECOMPRESSION PROCEDURES COURSE?
JJ-CCR Air Diluent Decompression Procedures Diver training is conducted in the open water of cenotes, with the additional (and recommended) option of ocean dives at a slight additional fee depending upon the boat costs and requirements. Both the inland dive sites such as Cenote Angelita and Laguna Kaan Luum and the ocean dive sites off of Puerto Aventuras and Akumal offer clear, warm water and ideal training conditions.
WHAT WILL I LEARN DURING THE JJ-CCR AIR DILUENT DECOMPRESSION PROCEDURES COURSE?
Under the Jungle’s JJ-CCR Air Diluent Decompression Procedures Training is conducted through TDI, and will cover equipment workshops, dive theory, confined water skills, and scenario practice.
⇒ EQUIPMENT WORKSHOPS
If you are already familiar with the JJCCR, great! The equipment used for decompression procedures will be similar to the equipment for air diluent diving with the optional addition of a 6 liter (40 cubic foot) O2 bottle. For divers who are crossing over from another unit, we will cover everything from set-up and breakdown, to equipment maintenance and key differences between the JJ-CCR and your previous unit.
⇒ JJ-CCR THEORY
We will review basic CCR theory as needed, and then focus on the unique theory for decompression diving. You’ll calculate gas requirements including bailout needs, and plan your dives based on oxygen and nitrogen limitations.
⇒ CONFINED WATER SKILLS ON THE JJ-CCR
The main difference between the air diluent level and the decompression procedures level will, of course, be executing decompression stops and dealing with bailout from deeper depths. We’ll also cover dropping and retrieving bailout cylinders and managing gas hemorrhages. In addition, we will run through the following skills during a checkout dive/skill evaluation in shallow confined water, and spot teach any skills that need reviewing:
• Pre-dive checks
• Establishing neutral buoyancy
• PO2 monitoring/awareness
• Proper kicking techniques
• Establishing minimum and ideal loop volume
• Constant loop volume management
• Controlled ascents and descents
• Mouthpiece familiarity drills
• Bailout drills
• Cell verification drills
• High-O2 and low-O2 procedures
• Dewatering the loop
• Manual PO2 management
• Mask removal and replacement
• SMB deployment
• Managing a CO2 breakthrough
• Loss of O2
• Loss/depleted diluent
• Electronics failure
• Gas extender drills
• Surfacing and towing an incapacitated CCR diver
⇒ OPEN WATER CCR DIVES AND SCENARIO PRACTICE
Open water dives under the supervision of your JJ-CCR instructor will allow you to practice and hone the skills you’ve developed in the confined water in a safe manner. This will give you a chance to refine and master your skills, and gain confidence with your JJ-CCR.
