The PADI Tec 40 course is where you transition from recreational scuba diving to technical diving. It’s a great place to start because it’s the first subdivision of the full PADI Tec Diver course and bridges the gap between no stop diving and full technical deep decompression diving. You gain experience and begin building the knowledge and skills you need to continue your tec diver training. You will qualify to make limited decompression dives to 40 metres/130 feet using blends of Nitrox / Enriched Air upto 60%.

*Note* This course may be combined with Tec45 and Tec50 to earn the "PADI TecRec Tec Deep" rating, a combination of all three courses taught concurrently*
