IANTD Triton CCR Rebreather Courses
Closed-Circuit Rebreathers (CCR) open the door to longer, quieter and more efficient dives. With
the Triton CCR, one of the most compact and versatile mechanical rebreathers available today, you
can explore deeper and more advanced diving environments while maintaining high safety
standards. On this page you will find an overview of CCR diving, the advantages of the Triton unit
and the typical training structure from entry-level to advanced levels.
What is a Closed-Circuit Rebreather?
Unlike open-circuit systems where exhaled gas is released into the water, a rebreather recycles the breathing gas inside a loop. Oxygen is added automatically or manually to maintain a constant partial pressure, while carbon dioxide is removed by the scrubber. This system reduces gas consumption and allows longer bottom times, efficient decompression and a quieter diving experience.
Advantages of CCR Diving
CCR diving offers several important benefits:
• Gas efficiency: The breathing gas is reused, significantly reducing consumption — especially helpful on deep trimix dives.
• Extended no-decompression times: A constant oxygen partial pressure limits inert gas uptake.
• Warm, moist breathing gas: Reused gas maintains warmth, increasing comfort on long dives.
• Minimal bubbles: Quiet diving helps to observe marine life without disturbance.
Why the Triton mCCR?
The Triton is a lightweight mCCR system weighing only 7 kg, making it ideal for travelling divers. It is the only CE-certified chest-mounted rebreather approved to 100 m for civilian use. Built by M3S in France, the unit is well known for reliability and performance in demanding conditions. Its compact chest-mounted design offers flexible configuration options, including sidemount, twinset or single-tank setups. The Triton can also be used as a bailout rebreather for explorative dives. Suitable for ocean, cave and wreck diving, it provides a highly adaptable platform for a wide range of CCR environments.
Triton CCR – IANTD Course Information
All Triton CCR training at Kaş Diving is conducted according to IANTD (International Association of Nitrox and Technical Divers) standards. The courses are taught on the Triton unit and focus on safe system handling, realistic skills application and responsible dive planning across all certification levels.

IANTD Triton CCR Recreational Diver
This entry-level IANTD Triton CCR course introduces you to closed-circuit diving and the safe operation of your unit. You learn buoyancy and loop control, gas management, system checks and basic emergency procedures. All dives are planned without decompression, with a maximum ppO₂ of 1.3 and to depths up to 30 metres.
Course info: No-decompression dives – maximum depth: 30 m – ppO₂ up to 1.3 – minimum 8 in-water sessions – minimum 420 min total training – confined and open water sessions included
Conditions: Minimum age 18 – Open Water + Nitrox (or equivalent) – minimum 20 logged dives / 15 h on open circuit – good overall health

IANTD Triton CCR Advanced EANx Diver
This IANTD course extends your Triton CCR training to planned decompression dives using air or nitrox as diluent. You develop advanced unit handling, bailout planning and safe decompression procedures for dives to 40 metres with a maximum ppO₂ of 1.3.
Course info: Mandatory decompression – maximum depth: 40 m – ppO₂ up to 1.3 – minimum 8 in-water sessions – minimum 480 min training – confined and open water – at least 2 dives deeper than 27 m
Conditions (pathway 1): IANTD Triton CCR Recreational Diver (or equivalent) – minimum 20 CCR dives / 20 h
Conditions (pathway 2): Deep + Nitrox Diver (or equivalent) – minimum 30 dives / 25 h on open circuit – at least 5 dives ≥ 30 m
IANTD Triton CCR Advanced Recreational Trimix Diver
This IANTD program introduces the use of trimix on the Triton CCR for planned decompression dives. You learn helium-based diluent planning, emergency procedures and the practical execution of dives up to 45 metres.
Course info: Mandatory decompression – maximum depth: 45 m – ppO₂ up to 1.3 – minimum 8 in-water sessions – minimum 480 min training – confined and open water – dive distribution includes: 2 ≥ 35 m, 2 ≥ 15 m, 2 between 40–45 m
Trimix Plus (optional): 2 additional dives – total runtime 60 min – at least 1 dive 40–45 m and 1 dive 42–51 m
Conditions: Same entry pathways as Advanced EANx – good overall health

IANTD Triton CCR Normoxic Trimix Diver
This IANTD course qualifies you for normoxic trimix dives on the Triton CCR to depths up to 60 metres (or up to 70 metres in the Plus program). The training covers advanced dive planning, bailout strategies and the safe execution of staged decompression dives with helium-based gases.
Course info: Maximum depth: 60 m (70 m Plus) – minimum 1 confined + 5 open-water dives – minimum 360 min training – ppO₂ and END limits according to standards – includes dives deeper than 45 m and 55 m
Conditions: Advanced EANx + CCR Deep Diver (or equivalent) – minimum 100 logged dives – at least 25 CCR dives / 50 h on unit (50% on same CCR) – minimum 10 CCR dives ≥ 30 m with decompression – minimum age 18
IANTD Triton CCR Trimix Diver
This is the highest level of IANTD Triton CCR trimix training and prepares divers for deep exploration dives to 100 metres. The course focuses on self-reliance, complex dive planning, helium gas strategies and problem-solving in demanding environments.
Course info: Maximum depth: 100 m – minimum 1 confined + 5 open-water dives – minimum 360 min training – at least 1 dive ≥ 75 m and 1 dive ≥ 85 m – ppO₂ and END limits according to standards
Conditions: IANTD Triton CCR Normoxic Trimix Diver (or equivalent) – minimum 100 CCR dives / 100 h – at least 50 dives and 50 h on the same unit – minimum 30 CCR dives ≥ 30 m with decompression (10 deeper than 50 m on helium after normoxic certification)
