Transition Into the World of Technical Diving

The PADI Tec 40 course is your first real step into technical diving. It’s designed for divers who are ready to move beyond recreational no-stop limits and begin exploring the world of decompression diving.

This course is a natural progression from PADI Tec Basics, but it can also serve as your first tec diving certification. Tec 40 bridges the gap between recreational diving and more advanced technical training, giving you the confidence, knowledge, and practical experience to safely extend your limits.
