Why PADI TEC 45?


The Tec 45 course picks up where Tec 40 leaves off and takes your training as a Tec diver further and deeper. It is the second sub-course in the full PADI Tec Diver course. You will learn the skills, equipment and planning needed to dive to a maximum of 45 metres/145 feet. You will acquire the knowledge to plan and execute single and repetitive decompression dives using a single stage cylinder of EANx or oxygen to accelerate or add conservatism to the decompression stops.
