Tec 40 and Tec 40 Trimix
The PADI Tec 40 course is where you transition from recreational diving to technical diving. It's a natural progression from Tec Basics, or it can be your first tec diver course. It is the bridge between no stop diving and technical decompression diving. You will 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 and use up to 50 percent oxygen as a decompression gas.
