The WOSD is an International diving organisation that uses as first diving organisation a new innovative training system, that is now also in use by other organisations; the so-called 'Digital Learning system'(D-Learning). With this system, the trainee receives a multi-media course package at the start of the course, with which they can learn the required theory 24 hours a day, 7 days a week. D-Learning gives the trainee the ability to study in their own time and in their own manner. Because WOSD is the owner of the IAHD, the IAHD now also benefits from WOSD's logistical resources and possibilities.
