Open Water Diver
Take the plunge - become an independent diver with the SSI Open Water Diver programme
The SSI Open Water Diver course
Your first dive certification. After the OWD you dive independently, worldwide, to 18 metres.
The SSI Open Water Diver course (OWD) is the starting point for all your diving adventures. After earning this internationally recognised certification, you can dive independently (always with a buddy) to 18 metres depth — anywhere in the world.
The course consists of three parts. You study the theory at your own pace via the SSI app or website, at home or on the go. Then comes a pool day: we practise all the basic skills in a controlled environment. After that, you complete four open water dives in the Grevelingenmeer.
We always work in small groups: maximum two students per instructor in open water. That means more personal attention, better learning and more enjoyment.

The standard OWD programme is a solid foundation for most students. But there is more to get out of it. Here are a few ways to enrich the course or hit the ground running afterwards.
OWD Plus — more dives, more experience
Your OWD certification is awarded after four open water dives. But the more you dive, the more comfortable and confident you become. The OWD Plus package adds two extra open water dives to the standard programme. Ideal if you want more time to practise, extra focus on specific skills, or simply want to enjoy more time diving in the Grevelingenmeer.

Nitrox
Nitrox (Enriched Air) contains more oxygen than regular air, allowing for longer dives and less nitrogen build-up. The Nitrox specialty pairs perfectly with the OWD course and can be completed directly after — or even during — the course. Ideal for divers who want to make multiple dives per day.

Perfect Buoyancy
Good buoyancy control is the foundation of diving. The Perfect Buoyancy specialty teaches you to fine-tune your trim, posture and breathing so you move through the water effortlessly and efficiently. Highly recommended straight after your OWD, while the core skills are still fresh.

Underwater Navigation
Knowing where you are and how to get back is an essential diving skill. The Navigation specialty teaches you to use a compass, recognise landmarks and explore a dive site systematically. It builds your independence and confidence underwater.
