SSI CCR Extended Range Trimix — Your First Step onto the JJ-CCR

Move from open circuit CCRAlready an experienced open circuit technical diver and ready to make the move onto the JJ-CCR? This SSI CCR Extended Range program with Will Cooper is designed as your first step into closed-circuit technical diving.You’ll learn to configure, operate and dive the JJ-CCR while transferring your existing technical diving knowledge into the closed-circuit environment. The course qualifies you to conduct staged-decompression dives to:45 metres using trimix with a minimum of 20% oxygenA maximum accumulated decompression time of 10 minutesDon’t already hold a decompression qualification?If you’re interested in learning to dive the JJ-CCR but don’t yet hold an appropriate open circuit decompression qualification, please see our separate SSI CCR Diving course listing.The CCR Diving program can be completed alongside the Extended Range training, providing a structured pathway from your current level through to CCR Extended Range certification. Contact us before booking and we’ll help you choose the correct training route.Train with Will CooperWill will guide you through the complete transition—from configuring your JJ-CCR and developing reliable pre-dive routines with checklists to dive planning, decompression procedures, bailout techniques and the management of realistic CCR failures.Every open-water training day concludes with a thorough video debrief and constructive, individual feedback. We are committed to your success, and if you need additional help to reach the required standard, we’ll be there to support you.What you’ll earnAfter successfully completing the program, you’ll receive the SSI CCR Extended Range certification.The certification qualifies you to dive with an equally or more highly qualified buddy, using specialised CCR equipment and procedures, to:45 metres with trimix diluent containing at least 20% oxygenA maximum staged-decompression obligation of 10 minutesCourse structureThe suggested total course duration is approximately 40 hours and includes:At least eight hours of academic developmentOne classroom and equipment-configuration dayConfined-water skills sessionsA swim assessment and progressive skill developmentSix open-water training divesDetailed daily debriefings and instructor feedbackA final examination requiring a minimum score of 80%at least 480 mins of CCR runtimeOnce enrolled, you’ll receive an email giving you access to the digital learning on the SSI App, allowing you to begin your academic preparation before the practical training starts.Entry requirementsYou must:Be at least 18 years oldHold Deep Diving and Enriched Air Nitrox certificationsHold an appropriate Extended Range Nitrox or CCR Diving qualification (with 30 hours) Meet all applicable experience and logged-dive requirementsIf you don’t yet hold the necessary decompression qualification, our SSI CCR Diving course may be completed as part of your training pathway. Final eligibility will be confirmed before the course begins.Equipment requirementsYou will need a complete JJ-CCR Total Diving System that is approved by SSI and holds the appropriate CE-type approval for the European market.Your equipment must also include:One bailout cylinder with a minimum internal volume of 5.7 litresA bailout regulator with an SPG and a second stage fitted with a one- to two-metre hoseOxygen-clean equipment where requiredA backup open-circuit or CCR-compatible computer for bailout following a system failureA surface marker buoyA spool or reel suitable for the planned depthA cutting deviceA surface-signalling deviceThe applicable manufacturer and/or SSI pre-dive checklistEquipment rental may be available. However, you’ll gain the greatest benefit from the course by training with and correctly configuring your own equipment.What’s includedSSI digital learning materialsAcademic developmentEquipment-configuration sessionConfined-water sessionSix open-water training divesThorough debriefing and ongoing instructor supportSSI certification following successful completionAdditional costsEntry fees for open-water training sites are not includedGases, sorb and all other consumables are charged separatelyRental equipment, if required, may incur an additional chargeReady to make the switch?Bring your open circuit technical experience to the JJ-CCR and discover a new way to approach extended-range diving. You’ll leave with a properly configured unit, disciplined operating procedures, stronger problem-solving skills and the confidence to safely plan and execute CCR trimix decompression dives.Your first breath on the JJ is the beginning of an entirely new way to dive.

Move from open circuit to CCRReady to leave the bubbles behind and make the move onto the JJ-CCR? The SSI CCR Diving program with Will Cooper is your entry point into closed-circuit rebreather diving.You’ll learn to configure, operate and dive the JJ-CCR while transferring your existing open-circuit knowledge into the closed-circuit environment. The course qualifies you to independently plan and conduct dives:To a maximum depth of 30 metresUsing air as the diluentWithin no-decompression limitsWith an equally or more highly qualified buddyThis is much more than learning how to use a new piece of equipment. You’ll develop the procedures, discipline and problem-solving skills required to safely dive a closed-circuit rebreather.Already hold a decompression qualification?If you’re an experienced open-circuit technical diver with an appropriate decompression qualification, take a look at our separate SSI CCR Extended Range Trimix course listing.Train with Will CooperWill will guide you through the complete transition—from configuring your JJ-CCR and developing reliable pre-dive routines with checklists to dive planning, buoyancy control, bailout techniques and the management of realistic CCR failures.Every open-water training day concludes with a thorough video debrief and constructive, individual feedback.
