How Training Works
Training begins with equipment selection, fitting and configuration, followed by land drills and progressive in-water sessions. Blue Water Ascent delivers this course over four days with a minimum of eight dives, exceeding the TDI agency minimum. Additional coaching may be recommended when more time is needed to achieve consistent, repeatable performance.
Course duration is performance-based. Meeting minimum attendance or dive numbers does not guarantee certification; all required knowledge and skills must be demonstrated consistently.
