Tec 40 CCR Diver

Tec 40 CCR marks the transition into technical closed-circuit diving. This course introduces decompression theory, staged ascent procedures, and disciplined CCR operation in a controlled technical environment.

You’ll learn to plan and execute dives using decompression strategies while maintaining precise control of your rebreather.

The Fun Part

This is where CCR diving truly opens up. Longer dives, better efficiency, and the ability to plan beyond recreational limits change how you think about underwater exploration.
