Open water training takes place at Groenendaal and Vinkeveen, and the outdoor season runs from May through September. Pool-based training and digital theory can be started year-round.
The Update Programme — also called opfriscursus or SSU — costs €130 for three pool sessions. It runs year-round on Sunday evenings at Sportplaza Groenendaal and is designed for certified divers who've been out of the water for a period and want to rebuild confidence before a dive trip.
