TDI Deco Procedures
Are you interested in the TDi Deco Procedures course and want to extend your bottom time?
As a recreational diver, you haven’t taken these steps yet.
In this course, you will learn to plan and execute decompression dives.
What is the TDI Deco Procedures?
A TDI Deco Pro Course – officially known as TDI Decompression Procedures Diver – is a technical diving course that teaches experienced divers how to safely conduct planned decompression dives. While recreational divers typically only dive within no-decompression limits (meaning they ascend without decompression stops), participants in this course learn how to intentionally and safely execute longer dives where a direct ascent to the surface is no longer an option.
