Are you looking for a challenge as a diver? Do you want to go a little beyond the possibilities that the PADI Tec 40 course offers you? The PADI Tec 45 course is your best option!

With the PADI Tec 45 you’ll extend your depth limit to 45 metres/145 feet and learn to plan and execute repetitive decompression dives using a single stage/decompression cylinder. It puts you in a complete tec diving rig. We will teach you the course in sidemount configuration, with which you will also acquire the Tec Sidemount certification! You’ll also make accelerated decompression dives using EANx or pure oxygen. This is a course where you’ll rise to the challenge and make the commitment to become a technical diver.

Tec 45 is the second step in your technical diving education. It’s the second of three courses which, if taken together and consecutively, would add up to what is known as the PADI Tec Deep – PADI Tec 40 + PADI Tec 45PADI Tec 50 = PADI Tec Deep
