Liberty is built from high quality materials that ensure safety and long term durability, even in the most demanding environments such as deep dives, cold water or saltwater conditions. Liberty is not just certified. It is trusted, proven through real diving experience.

Safety is at the core of Liberty’s design. All critical parts have a backup, allowing the rebreather to keep operating even if one part fails. Each part of Liberty is engineered to stay safe and functional, even when something goes wrong.

Every Liberty rebreather is built to meet the highest standards of quality 
and safety.

Developed and manufactured in the Czech Republic, created by divers for divers.

Liberty continuously analyzes and adjusts the gas you breathe, maintaining the optimal mix of oxygen and diluent at every depth. Its intelligent control system monitors data from more than a dozen sensors — including depth, pressure, temperature and oxygen levels — to keep breathing smooth,safe and efficient.

Main functions:

Real time analysis
The system processes information from all sensors several times per second. It automatically maintains the ideal breathing mix for minimal decompression and maximum comfort.

Smart oxygen control
Liberty injects oxygen and diluent as needed to hold the selected setpoint. In case of sensor deviation, the system detects and isolates the fault automatically.

Adaptive performance
The control units continuously adjust to changing conditions, such as temperature or workload, ensuring accurate and stable readings throughout the dive.

Complete awareness
Two independent handsets display all key information in real time, giving the diver full confidence and control without distraction. Every part of Liberty works together to deliver one outcome — quiet, efficient and reliable breathing in every situation.

All Liberty rebreathers share the same core technology, electronics and control logic. Each configuration is designed for a different style of diving — from travel and training to exploration and professional missions. With optional conversion kits, you can easily switch between Backmount, Sidemount, Light and Heavy setups using a single Liberty head, HUD and handsets. One platform, endless possibilities.

Backmount
Comfortable, stable and suitable for all types of diving, from training to exploration.

Sidemount
A compact version for cave, wreck and travel diving. Streamlined and perfectly balanced for confined or restricted environments.

Light
A lighter configuration for divers who prefer a smaller and more travel friendly setup. Simple to handle and ready for everyday use.

Heavy
A durable configuration for longer or more demanding dives. Designed for endurance, extra gas supply and reliability when it matters most.

Every configuration shares the same Liberty core, ensuring familiar controls, consistent performance and complete confidence in every dive.

Dive log and analysis
The app stores detailed information about each dive, including gas usage, depth profile and system performance. It helps you review and understand your dives directly on your phone or tablet.

System updates
Firmware updates and diagnostics are handled directly through the app, keeping your rebreather always up to date and performing at its best.

Personalization
The app allows you to adjust user settings, such as display preferences or setpoint configurations, so Liberty feels perfectly tuned to your diving style. The connection between Liberty and the Divesoft App keeps your system organized, modern and ready for every dive.

Maintenance
Liberty is designed for long term use and straightforward maintenance. Regular service ensures consistent performance, maximum safety and a long lifespan of the system.

Recommended service intervals:

Annual service
Visual inspection, functional testing and software updates to keep the rebreather operating at peak performance.

Three year service
Complete system check including O-rings, sensors, batteries and pressure tests to verify full functionality.
