Contact WOSD

WOSD is not standing still.
The 'eyes and ears' in the field are therefore very important to us. We want to keep the lines short and therefore have 'Regional Managers' in the field. If a diver or an instructor sees additions and / or improvements, please let us know. Together we can remain innovative and strive for an even better system in which safety, fun and good education are central. Anyone can contact WOSD via the contact form or via one of our Regional Managers.
