Check out the Divesoft Youtube channel for a detailed introduction of the Liberty rebreather.

The course begins by tracing the fascinating evolution of rebreather technology. From the humble beginnings of ancient diving bells to the cutting-edge systems of today, you’ll discover the transformation that has made modern diving safer, more efficient, and infinitely more thrilling. Discover the science behind closed-circuit rebreathers, which enable longer dives by recycling exhaled gases. Explore the remarkable features of the Liberty CCR, understanding how its innovative design enhances buoyancy control and dive efficiency.

As you complete the Liberty Side Mount CCR training course – MOD 1 or Crossover with TDI, you’ll be able to join a community of divers who have embraced the future of diving technology. Welcome to a world where silence speaks volumes, and every dive is a symphony of discovery.

Most of your underwater training will occur in the Cenotes. These dive sites are not only magical and unique, but there are also many advantages to training in them. training in the Cenotes.

The theory portion of the Advanced Nitrox course starts with the e-learning at your own pace then conducted in the classroom at Deep Dark Diving and during the briefings and debriefings. Confined water skills are practiced in shallow water in the cenotes such as Cenote Eden, Cenote Orquidea, and execution dives are completed in deep Cenotes, such as Cenote Angelita, Cenote Yaakun, Cenote Maravilla, Cenote Kin Ha.

Curious about the quiet, bubble-free world of rebreather diving? A CCR (Closed Circuit Rebreather) try dive in the stunning cenotes of Mexico offers you the chance to explore underwater in silence, allowing for closer interactions with marine life and better buoyancy control. This experience is perfect for divers who want to take their skills to the next level or underwater photographers tired of bubbles ruining their perfect shot.

Your CCR try dive on the Divesoft Liberty Sidemount rebreather will last about 5-6 hours, including:

  • A pre-dive briefing and setup overview
  • Learning about how rebreathers work, the scrubber, gases, and monitoring systems
  • A hands-on dive where you’ll experience the silent world of CCR diving at a max depth of 6 meters in a Cenote

You’ll also get insights on key safety protocols, including how to manage buoyancy and perform a bailout if necessary.

If you enjoy the try dive and want to continue your journey into CCR diving, we offer the TDI Mod1 air diluent course, TDI Air Diluent CCR Decompression Procedures Diver and cross over for certified CCR divers. You can choose from backmount or sidemount configurations to suit your diving style.

With no bubbles and better buoyancy control, CCR diving opens a whole new underwater experience. Book your rebreather try dive today and explore the cenotes like never before!

Rebreather units, while based on the same core principles, can differ greatly in their design, gas flow systems, emergency protocols, and other key features. If you’re already a certified TDI Air Diluent CCR Diver or hold an equivalent certification, and you want to qualify on the Liberty Sidemount CCR, our crossover course is designed to meet your needs. This course ensures that you master the specifics of the Liberty Sidemount CCR while adhering to all TDI unit-specific standards and skill requirements.
