The course is intended to challenge divers in a comfortable environment that emphasizes the need for learning management, maintenance procedures and protocols of the closed-circuit rebreather. The course also emphasizes the need for increased physical and mental fitness.

GUE's Closed-Circuit Rebreather Diver Level 1 course is intended for GUE Tech 1 divers who desire to learn to dive with a closed-circuit rebreather. Tech 1 divers who aspire beyond their current level will find that this course gives them the tools to do so by building and enhancing their technical diving abilities.

Course outcomes include, but are not limited to: a competent and comfortable rebreather diver with solid personal and team skills; knowledge of rebreather functions, operation and how to act if experiencing failures; competent in performing bailout to open circuit, including ascent protocol; and can plan technical dive missions including, gas, absorbent canister endurance, oxygen toxicity management and decompression strategies.

The course is also designed to extend diver capacity for challenges in a comfortable learning environment by emphasizing a higher degree of physical fitness, as well as a deeper understanding of the management, maintenance procedures, and protocols of the rebreather.

GUE's Closed-Circuit Rebreather Diver Level 2 is intended for graduates of the GUE Closed-Circuit Rebreather Diver Level 1 course who wish to further their knowledge and understanding of advanced CCR diving in more demanding environments. Students of this class wish to enhance their capacity of CCR diving within the GUE system.

Course outcomes include, but are not limited to: a competent and comfortable rebreather diver with solid personal and team skills, robust knowledge of rebreather functions, operation, and failures; competent performing deep bailout to open circuit, including ascent protocol involving gas switches, rotations, and loss of decompression gases; and a diver that can plan aggressive technical dive missions including, gas, absorbent canister endurance, oxygen toxicity management and decompression strategies.

For those who would prefer to have their units serviced by a qualified and JJ-CCR factory-trained technician, we are happy to help - contact us today to book your unit in for any servicing work it may require. As an authorised JJ-CCR Service Centre, we only use genuine JJ-CCR parts and work to the highest standards.

If you're the sort of person that would like to learn the skills and knowledge required to competently service the JJ-CCR for yourself, why not book a service day with us at our workshop and we'll go through the servicing with you? You are permitted to do this as part of your warranty agreement with JJ-CCR and, whilst you won’t be a service technician after this, our workshop will give you a better insight into your rebreather and the knowledge you need to perform field repairs and preventative maintenance. There are many tips and tricks to be learned and a deeper knowledge of the unit function and design. We can help with 1- and 2- year services and provide original replacement part that are needed for this maintenance.

During servicing we would inspect and confirm function of all major parts of the rebreather. In particular, the DSV, breathing hoses and connections, counter lungs, ADV, solenoid and battery compartment would be covered and soft parts - o-rings, diaphragms and flapper valves - would be replaced according to service interval and/or necessity.

The electronics are sealed and don’t need routine maintenance, only a superficial inspection. Furthermore, first stages will be checked for correct function and setting but servicing of them and also tanks is outside of the scope of this maintenance day but can be arranged.
