It is common and natural for self-taught free divers or spear fishers (i.e. free divers that have never attended a free diving course, nor have they ever been certified by a free diving institute) to posses the know how and skills of a certain course level.
The 1st level is an introductory course to free diving and is aimed to divers with little on no free diving experience.
It is a course, designed to offer friendly, simple and quick learning to enable the new free diver to move in the underwater environment with safety.
This is the FDI middle level free diving course and is aimed to free divers that already possess the FDI 1st Level certification, or a certification of another organization of similar stature, or self-taught free divers and spear fishers who posses the skills and qualifications of the 1st level course.
