Open Water Diver

The OWD at Happy Divers runs on the SSI curriculum — the centre switched from PADI to SSI in December 2024, with Czech-language digital study materials one of the stated reasons. Theory preparation goes through the SSI elearning platform, which students work through at their own pace, followed by a classroom session at the centre on Veletržní 31, Praha 7, where harder topics get covered and the specifics of the open water dive location get discussed.

Pool sessions use three venues in the Prague and Mělník area: Sport centrum ČZU on Kamýcká in Praha 6 (Thursdays 19:00–21:30, September through June), Krytý bazén Mělník (Wednesdays 20:00–22:00), and Bazén Slavia on Vladivostocká in Praha 10 (Mondays 20:00–21:00). In July and August the outdoor pool in Mělník takes over. Five training modules typically fit into four pool visits. Groups run at a maximum of six students, with a qualified instructor and assistants throughout every session.

The four mandatory open water dives happen at Czech quarries — Bořená Hora is a regular venue — or optionally in Germany (Horka, 35 m max), Croatia or Egypt. The first dive focuses on getting comfortable in open water and exploring the environment. Dives two through four open with skills practice from the pool sessions, then shift to diving for its own sake. Weekends at Czech quarries are the default path; students who want something warmer and saltier can fold the open water dives into one of the centre's regular international trips to Croatia, Egypt or elsewhere.

The full 12,900 Kč price covers SSI OWD digital materials and certification fee, theory instruction, four to five pool sessions, four open water dives in the Czech Republic, a logbook, full equipment loan for open water sessions (mask, snorkel, fins and dive computer), and equipment transport to the pool. Not included: personal transport to pools or quarry sites, quarry entry fees, air fills outside Happy Divers, and a supplement for completing the course abroad at some locations. A referral option exists for 9,500 Kč — theory and pool work in Prague, open water dives at any centre worldwide, paid separately to that centre. A fully individual course with one-on-one instruction is available at 19,800 Kč.

Every graduate gets ongoing discounts on gear purchases at the shop, reduced rental rates and no deposit requirement on borrowed equipment. The centre also uses the OWD as the starting point for its full programme of club quarry weekends, international trips and advanced courses.
