Here you will find all WOSD (educational) materials and the WOSD library.
For children from 8 to 12 years old who want to follow a primary course or a specialty course, there are the WOSD youth courses.
WOSD youth courses are characterised because the theoretical knowledge and practical skills of the courses are adapted to the level of knowledge and motor skills of children.
WOSD primary courses are developed for the student who has no experience with the underwater world.
The main purpose of the courses in this group is to gain a basic understanding of the dive theory and practical skills, which are essential for safe and responsible diving.
The recreational specialty programs of WOSD are developed to gain more advanced understanding in a specific diving activity.
During a recreational specialty program normal compressed air is used as a breathing gas and a direct ascent to the surface is always possible.
