Take your diving skills to another level wit the PADI TEC 50 technical diving course.
Increase your knowledge of diving even further and extend your depth range to 50 meters and your and increase your bottom time/decompression time ratio by using 2 deco gasses of up to 100%.
Using 2 different decompression gases will allow you to start decompressing deeper and will therefore decrease the time required for decompression.
On the TEC 50 course you will learn how to dive with 4 cylinders using the sidemount rigging. While this sounds like a lot of tanks to handle on a dive, it is surprisingly easy, once you get to it.
