PADI Tec 40 CCR Course | Entry-Level Technical CCR Certification

The PADI Tec 40 CCR Course is the first step into technical closed-circuit rebreather (CCR) diving, bridging the gap between advanced recreational CCR diving and full technical CCR decompression diving. This course introduces divers to limited decompression, trimix/heliox awareness, and technical CCR procedures within clearly defined limits.

At Extreme Watersports, the PADI Tec 40 CCR Course is conducted on the Dive Rite O₂ptima CM, providing a robust and proven CCR platform suitable for technical progression.

What Is the PADI Tec 40 CCR Course?

The PADI Tec 40 CCR Course trains divers to plan and execute technical CCR dives with limited decompression obligations using a closed-circuit rebreather. Divers learn to manage increased task loading, execute controlled ascents with decompression stops, and apply disciplined CCR procedures in a technical diving context.

This course represents the transition from recreational CCR diving to technical CCR diving.

Course Objectives

By the end of the PADI Tec 40 CCR Course, divers will be able to:

• Plan and execute technical CCR dives within Tec 40 limits

• Conduct limited decompression using a CCR

• Maintain precise buoyancy, trim, and ascent control

• Manage PPO₂ manually and automatically under task loading

• Plan and execute bailout strategies for technical CCR dives

• Identify and respond to CCR failures and malfunctions

• Apply standardized technical CCR procedures and team protocols

Course Structure

The PADI Tec 40 CCR Course consists of:

Knowledge Development

• Technical CCR dive planning principles

• Decompression theory for CCR diving

• Gas density and narcosis considerations

• Bailout planning and gas selection

• Risk management and contingency planning

Confined / Controlled Water Training

• Advanced CCR skills and drills

• Manual PPO₂ control

• Bailout execution and emergency responses

• Task-loaded skill performance

Open Water Technical CCR Dives

• Technical CCR dive planning and execution

• Limited decompression profiles

• Controlled ascents and decompression stops

• Real-world application of Tec 40 CCR procedures

PADI Tec 40 CCR Course Requirements

To enroll in the PADI Tec 40 CCR Course, students must meet the following requirements:

• Minimum age: 18 years

• Certification prerequisite:

  • PADI Advanced Rebreather Diver or equivalent CCR certification

• Experience:

  • Minimum number of CCR dives as required by PADI TecRec standards

• Medical:

  • Medical clearance for diving (if required)

Depth & Decompression Limits

• Maximum depth: 40 meters / 130 feet

• Decompression: Limited decompression within PADI Tec 40 CCR limits

• Gas: Diluent air or trimix/heliox as permitted by standards and conditions

Equipment Requirements

• Closed-circuit rebreather (Dive Rite O₂ptima CM)

• Bailout cylinder(s) and regulators

• CCR-compatible technical dive computer

• Redundant monitoring and safety systems

• Appropriate exposure protection

All equipment configurations are standardized and reviewed before diving.

Certification & Progression

Upon successful completion, divers receive PADI Tec 40 CCR certification, qualifying them to:

• Conduct limited decompression technical CCR dives

• Dive to a maximum depth of 40 m / 130 ft within limits

• Progress to PADI Tec 60 CCR training

Tec 40 CCR certification confirms readiness to enter technical CCR diving under structured limits.

Training Platform – Dive Rite O₂ptima CM

The Dive Rite O₂ptima CM is selected for Tec 40 CCR training due to its:

• Manual and electronic PPO₂ control

• Robust and modular design

• Compatibility with advanced technical CCR progression

• Proven reliability in training and expedition environments

Training on the O₂ptima CM ensures skill transferability to higher-level technical CCR courses.

Why Take the PADI Tec 40 CCR Course?

This course is ideal for divers who:

• Want to transition from recreational to technical CCR diving

• Seek formal technical rebreather certification

• Want to learn limited decompression on CCR

• Plan to progress toward deeper and more complex CCR dives

• Value disciplined procedures and structured progression

After Certification – What’s Next?

After completing the PADI Tec 40 CCR Course, divers are encouraged to:

• Build experience through guided CCR dives

• Progress to PADI Tec 60 CCR for deeper decompression diving

• Continue skill refinement before increasing complexity
