Simplicity Beneath the Screen: Why the Liberty CCR Makes Complex Dives Easy

12/08/2025

Closed-circuit rebreathers often intimidate divers. Many imagine complicated assembly, constant adjustments, and demanding underwater management. The Liberty CCR was designed to eliminate these concerns.

Although Liberty is one of the most sophisticated CCR systems available, the user experience is remarkably simple. The device, together with the Divesoft.app mobile application, guides the diver through assembly, calibration, and system verification step by step. Underwater, Liberty automates the complex internal work, letting divers focus on exploration, enjoyment, and mission—not the equipment.

High-tech inside. Calm and simplicity on the outside.

Why Rebreathers Seem Complicated (and Why Liberty Isn’t)

Most divers thinking about switching to CCR worry about:

  • Complicated assembly
  • Fear of incorrect calibration
  • Long checklists they might forget
  • Risk of leaks or system errors
  • High mental load during the dive
  • Liberty CCR directly addresses these pain points.

Its design principle is clear:
Guide the diver through everything—visibly, logically, and safely.
The diver remains firmly in command.

Liberty doesn’t overwhelm new users, yet it offers unmatched control options for experienced divers.

The Role of Divesoft.app: Step-by-Step Assembly and Calibration

One of Liberty’s greatest strengths is that the assembly and calibration are not done on the device display. They are guided entirely through the Divesoft.app mobile application, which leads the diver through the process with absolute clarity.

1. App-Guided Assembly

The mobile app walks the diver through every step of building the unit:

  • Attaching components
  • Securing connectors
  • Verifying installation order
  • Ensuring loop components and scrubber are properly assembled

Each step is confirmed visually and interactively, greatly reducing the risk of assembly mistakes.

2. Calibration Built Into the Assembly Process

Oxygen sensor calibration—one of the tasks beginners fear most—is fully guided inside the app.

The diver simply follows the on-screen steps. The app ensures:

  • Proper exposure of sensors
  • Correct calibration sequence
  • Stability and validity of sensor readings
  • This makes calibration easy even for first-time CCR users.

Pre-Dive Check: Performed on the Liberty Display

Once the unit is assembled and calibrated through the app, the Liberty CCR display takes over for the pre-dive check.

This is where Liberty shines with its clarity and automation.

What the Pre-Dive Check Confirms

  • Connectivity and functionality of all electronics
  • Oxygen sensors (accuracy, agreement, stability)
  • Pressure sensors
  • Solenoid and MAV performance
  • HUD and controller communication

And critically:

  • Negative and Positive Pressure Checks Liberty is unique in that it monitors internal pressure changes during negative (vacuum) and positive pressure tests.

These tests confirm:

  • The unit is airtight
  • No leaks threaten flooding
  • The diver can trust the loop even on long or deep dives

For many instructors, this is one of the most confidence-building features of Liberty.

Final Pre-Jump Checklist: The Last Step Before Entering the Water

Just before entering the water, Liberty presents one more checklist on the screen—simple, essential, and easy to follow.

It confirms:

  • Diluent valve open
  • Sufficient diluent supply for the planned dive
  • All diluent-dependent components functioning (ADV, BOV, inflator)
  • Oxygen valve open
  • Oxygen MAV and solenoid functioning correctly
  • Correct gas settings
  • Bailout cylinder ready
  • Suit inflator connected
  • Primary light ready
  • Reminder to monitor PO₂ and CO₂ levels

Everything is checked before splashing in.

Pre-Breathe: Guided, Simple, and Reassuring

During this phase, the diver verifies that:

  • The unit adds oxygen at expected intervals
  • The solenoid maintains the chosen setpoint
  • Breathing resistance feels normal
  • The loop behaves predictably as temperature stabilizes

This ensures everything is perfectly ready before descent.

Despite requiring full attention, the process is never overwhelming, because both the app and device display lead the diver through every action.

Diver in Command: The Core Philosophy Behind Liberty CCR

Even with such comprehensive guidance, Liberty is built on the principle that the diver always has the final word.

Liberty assists—it never overrides.

Expert Tools for Non-Standard Situations

Experienced divers can:

  • Override setpoints
  • Switch to manual oxygen addition
  • Adjust PPO₂ control behavior
  • Modify alarm levels
  • Change decompression strategies
  • Adapt bailout and control logic
  • ... and many other changes and adjustments

This makes Liberty suitable for expedition divers, explorers, and professionals, without making the system harder for beginners.

Beginner Simplicity, Expert Capability

Advanced settings remain unobtrusive. New users interact only with the basics:

  • PO₂ display
  • Depth, time, ascent info
  • Automatic setpoint switching (optional)

Liberty feels simple to a novice but offers depth and flexibility to experts.

During the Dive: Liberty Manages the Complexity for You

Once underwater, Liberty continues to reduce workload.

1. Automatic Setpoint Control

If enabled, the unit automatically adjusts oxygen setpoints according to:

  • Descent
  • Bottom time
  • Ascent

The diver monitors PO₂—rarely needing to intervene.

2. Redundant Sensor Monitoring

Multiple sensors provide cross-checking. Any inconsistency triggers a clear, timely alert.

3. Minimal Task Loading

Underwater, the diver focuses on:

  • PO₂
  • Depth
  • Time
  • Required ascent time

Liberty handles the rest behind the scenes.
