The future of deep tec diving belongs to the CCR (closed circuit rebreather) and the Tec 40 CCR course is where it all starts. If you're interested in technical diving and want to dive a rebreather, the Tec 40 CCR course is your entry into the tec diving realm. This first level of training introduces you to Type T CCRs, which can be electronic CCRs (eCCRs) and manual CCRs (mCCRs). During the course, you focus on developing the discipline it takes to be a technical diver while learning the details of proper setup, predive checks, dive planning, failure and problem management, and teamwork for CCR diving.

To take a Tec 40 CCR Diver course, you must:

• Be a PADI Advanced Open Water Diver
• Be a PADI Enriched Air Diver
• Be a PADI Deep Diver or show proof of 10 dives to 30 metres/100 feet
• Have a minimum of 30 logged dives, with at least 10 dives using EANx deeper than 18 metres/60 feet
• Be at least 18 years old
• Before Training Dive 5, be certified as a PADI Rescue Diver
• Before certification, have at least 50 logged dives

Note that qualifying certifications from other diver training organizations may apply - ask your Tec 40 CCR Instructor.
