The PADI Tec 40 course is where you transition from recreational to technical diving. It is a great way to start because it’s the first subdivision of the full PADI Tec Diver course, bridging the gap between no decompression diving and deep technical decompression diving. You gain experience and begin to build the knowledge and skills you need to continue your technical diver training. You will be accredited to do decompression dives up to 40 meters.
