TDI Rebreather Discovery Program | Introduction to CCR Diving

The TDI Rebreather Discovery Program is an introductory experience designed for certified scuba divers who want to discover closed-circuit rebreather (CCR) diving before committing to a full CCR certification course. This program provides a controlled, instructor-led introduction to rebreather diving, allowing participants to experience the fundamentals of CCR operation in a safe and structured environment.

At Extreme Watersports, the TDI Rebreather Discovery Program is conducted on the Dive Rite O₂ptima CM, a proven and widely used closed-circuit rebreather suitable for training and progression into advanced CCR diving.

What Is the TDI Rebreather Discovery Program?

The TDI Rebreather Discovery Program is not a certification course. It is a discovery experience that allows divers to:

• Learn how a closed-circuit rebreather functions

• Experience breathing from a CCR underwater

• Understand basic CCR procedures and safety concepts

• Decide whether CCR training is the right next step

This program is ideal for divers considering TDI CCR courses or future rebreather certification.

Program Objectives

By the end of the TDI Rebreather Discovery Program, participants will:

• Understand the basic components of a CCR

• Learn fundamental rebreather safety principles

• Practice basic loop breathing and buoyancy control

• Monitor PPO₂ under direct instructor supervision

• Gain familiarity with CCR procedures and terminology

Program Structure

The TDI Rebreather Discovery Program typically includes:

Knowledge Briefing

• Introduction to closed-circuit rebreather diving

• Basic CCR concepts and terminology

• Oxygen management and PPO₂ awareness

• CO₂ considerations and scrubber overview

• Safety limits and operational discipline

Confined / Controlled Water Session

• CCR setup and basic pre-dive checks

• Loop breathing and volume control

Depth Limits

• Maximum depth: As defined by TDI Discovery standards
  (Typically shallow, non-decompression limits.)

Training Platform – Dive Rite O₂ptima CM

The Dive Rite O₂ptima CM is used for the Rebreather Discovery Program due to its:

• Stable breathing characteristics

• Manual control capability

• Proven reliability in training environments

• Seamless progression into full CCR certification

This ensures continuity if the diver later enrolls in TDI CCR training.

Is the TDI Rebreather Discovery Program Right for You?

This program is ideal for divers who:

• Are curious about CCR diving

• Want to experience rebreather diving before certification

• Are considering TDI CCR courses

• Prefer a structured, instructor-led introduction

• Want hands-on experience with a closed-circuit rebreather

After the Rebreather Discovery Experience

After completing the TDI Rebreather Discovery Program, participants may:

• Enroll in a TDI CCR certification course

• Progress through structured CCR training pathways

• Join guided CCR dives after certification

The discovery experience provides valuable insight before committing to full CCR training.
