DiveSoft Liberty Sidemount CCR

Overview

In this course, you’ll learn how to configure and manage a sidemounted CCR system, fine-tune buoyancy and trim for optimal performance, and handle emergency scenarios with confidence. The teaching is based on the Divesoft Liberty Sidemount CCR, the most up-to-date, state of the art piece of CCR in the market. Whether you’re exploring tight caves, intricate wrecks, or simply looking to enhance your diving versatility, theh Divesoft Sidemount CCR opens up a whole new level of adventure.

Course Objectives

Develop the skills and knowledge necessary to safely dive a Closed Circuit Rebreather.
Understand the principles of gas management, equipment configuration, and emergency protocols.
Learn how to extend bottom times, reduce gas consumption, and minimize decompression stress.

Course Outline

1. Theory and Knowledge Development (Day 1–2)

Rebreather Fundamentals:

- What is a CCR? Differences between open circuit (OC) and closed circuit systems.

- Benefits and limitations of CCR diving.

Equipment Overview:

- Anatomy of the Liberty CCR: loop, scrubber, oxygen sensors, counter lungs, electronics and more.

- Types of rebreathers: manual (mCCR), electronically controlled (eCCR).

Gas Physics and Physiology:

- Partial pressure of oxygen (PO2) management and setpoints.

- Understanding oxygen toxicity, hypercapnia, and hypoxia risks.

- Decompression theory and CCR-specific considerations.

Gas Management:

- Oxygen and diluent use.

- Importance of bailout systems and dive planning.

Safety and Emergency Procedures:

- Manual overrides, bailouts, and dealing with system failures.

- Risk mitigation strategies for equipment failure or diver error.

2. Equipment Setup and Maintenance (Day 2–3)

- Pre-dive checklists and system assembly.

- Scrubber material preparation and replacement.

- Battery charging and electronics testing.

- Cleaning and post-dive maintenance.

3. Confined Water Training (Day 3)

- Introduction to breathing on a CCR loop.

- Bubble check and buddy check.

- Buoyancy control with a rebreather.

- Mask clearing and loop flood recovery.

- Managing PO2 setpoints.

- Basic emergency drills (e.g., bailouts, simulated oxygen sensor failures).

4. Open Water Training Dives (Day 4–6)

- Applying CCR skills in real-world diving scenarios.

- Dive planning with CCR considerations (gas supply, bailout, and PO2 management).

- Navigation and situational awareness while on a rebreather.

- Mode trouble-shooting techniques: handling hypoxia, hyperoxia, hypercapnia, BOOM scenario

- "Staying on the Loop" - Manual CCR mode, SCR mode

*Dive Progression*:

- *Dive 1–2*: Basic buoyancy, breathing techniques, and equipment familiarity.

- *Dive 3–4*: Emergency procedures and troubleshooting in open water.

- *Dive 5+*: Longer dives with decompression planning (if advanced level).

A minimum of 500 minutes of bottom time required for the certification of new CCR divers.
