PADI Tec 45 & Tec 45 Trimix Diver – Dive Deeper, Stay Longer, Think Sharper at Diving Academy
At Diving Academy, we help you push beyond limits with skill, confidence, and control. The PADI Tec 45 & Tec 45 Trimix Diver course takes your tec diving to the next level—allowing you to dive to depths of 45 metres, manage longer decompression times, and work with a wider range of gases, including Trimix.
This course is designed for divers who want to build on their Tec 40 training and explore deeper, more complex dive profiles.
