The BSAC Advanced Ocean Diver course includes both theory and practical training designed to build your confidence and competence in deeper and more complex diving situations. The emphasis is on safe planning, efficient use of equipment, and sound decision-making underwater.
Assessment is continuous and based on your ability to demonstrate safe and effective diving practices during the course. Upon successful completion, you’ll be issued a BSAC Advanced Ocean Diver certification, recognised internationally.
As always, course delivery may vary slightly between centres, especially in terms of dive sites and scheduling. Your local club or BSAC school will advise on specifics. And don’t forget — once certified, adventuro can help you find your next dive adventure, whether it’s a UK wreck tour or a warm-water holiday abroad.
Once certified, a BSAC Advanced Ocean Diver is qualified to dive to depths of up to 30 m / 100 ft with a similarly qualified buddy. This opens the door to a wider range of dive sites, including deeper wrecks, offshore reefs, and more demanding underwater environments. You’ll also be more confident in dive planning, gas management, and navigating underwater — all essential skills for progressing in the sport.
The certification enables you to join more advanced club dives and is a recognised prerequisite for the BSAC Sports Diver course. It also improves your standing with dive operators worldwide, as it demonstrates comfort and control at intermediate depths. Many divers use the Advanced Ocean Diver qualification as a stepping stone toward more technical or leadership-focused training in the future.
And remember — adventuro lists hundreds of guided dives, training courses and kit rentals across the UK and beyond, so you’ll have plenty of opportunities to put your new skills into practice.
The Advanced Ocean Diver course typically takes place over 2 to 3 days, depending on local conditions and schedules. It includes classroom sessions, confined water refresher work if needed, and at least four open water dives to depths of up to 30 m / 100 ft. Some training centres may spread the course over several weekends or combine it with club trips to maximise real-world experience.
The BSAC Advanced Ocean Diver course is a performance-based qualification that builds on core diving skills with a focus on navigation, depth progression, and safety planning. Assessment occurs during a series of open water dives where instructors observe your ability to manage depth, use a dive computer effectively, navigate underwater, and respond to real-world scenarios. There’s no written exam, but you’ll be expected to plan dives, demonstrate good buoyancy control, and make safe decisions. Most divers complete the course over 5–6 open water dives, with optional theory sessions provided by the centre. If you need extra time to master any part, instructors will support you with additional sessions. Once qualified, you’ll be certified to dive to a maximum of 30 metres with a similarly qualified buddy. You can browse and book BSAC courses and centres through adventuro's extensive listings.

Find activitiesTo enrol on the BSAC Advanced Ocean Diver course, you need to be a certified BSAC Ocean Diver or hold an equivalent entry-level qualification from another recognised training agency, such as PADI Open Water Diver or SSI Open Water Diver. You should also have recent diving experience and be comfortable diving to 20 metres. Your centre may ask for a diving medical form and a logbook showing your recent dives.
This course focuses on deep diving (up to 30 metres), underwater navigation, and dive planning using nitrox and dive computers. You'll also practise controlled ascents, DSMB deployment, and managing gas supply. These are all essential skills for diving in more challenging environments and planning dives independently with a buddy.
Typically, the Advanced Ocean Diver course takes 2–4 days to complete, depending on the dive centre and local conditions. This includes five open water dives, plus briefings and debriefings. Some centres offer theory refreshers or online learning ahead of time, which can reduce time on-site. Always check with your chosen centre for specific schedules.
Yes. If you have an equivalent certification from another recognised diving agency—like PADI, NAUI, or SSI—you can join the BSAC Advanced Ocean Diver course. You may be asked to provide evidence of your training and experience, such as your certification card and dive log. The instructor may also do a quick check dive to assess your comfort level in the water.
You’ll need a full set of standard scuba gear, including a dive computer and delayed surface marker buoy (DSMB). Most centres can provide rental equipment if you don’t have your own. Some also include gear hire in the course price. It's a good idea to check in advance what is provided and what you’re expected to bring.
No, the BSAC Advanced Ocean Diver course does not include a formal written exam. Instead, instructors assess your knowledge through dive planning sessions and on-the-spot questions during briefings. You'll need to demonstrate a sound understanding of dive theory, including dive tables, gas planning, and using a dive computer.
Once qualified as a BSAC Advanced Ocean Diver, you can dive to a maximum depth of 30 metres when accompanied by a diver of the same or higher qualification. You should always dive within your comfort zone and experience level, and build up to deeper dives gradually as you gain confidence and practice.
While BSAC Ocean Diver certifies you to dive to 20 metres, the Advanced Ocean Diver extends that limit to 30 metres and introduces more complex dive planning and navigation. It’s designed to boost your confidence and prepare you for more adventurous or technical diving routes within BSAC’s training framework.
BSAC Advanced Ocean Diver courses are offered by BSAC clubs and centres across the UK and internationally.
