This one takes five. That extra time isn't padding. It's skill repetition, the thing that turns techniques you've just learned into reflexes you can rely on. Buoyancy, trim, gas awareness, and underwater confidence don't come from doing each skill once. They come from doing it until it stops feeling difficult. The foundations built here aren't beginner skills that get replaced later. Every diver who eventually trains at 60 metres is using the same buoyancy control and situational awareness that gets started in Open Water. If those foundations are solid, everything that comes after them is easier. If they're not, the gaps show up later, at depth, in current, or in conditions that aren't cooperative. Two students maximum per instructor. In the water from day one. ## What's included - 2 pool / confined water sessions - 6 open water dives - PADI Open Water certification - All dive centre fees (tanks, weights, boat, sites) ## Who this is for - Anyone starting from zero who wants to learn diving properly - Adults and teens (14+) comfortable around water - Not the right fit if you want the fastest certificate available ## What you need before you start - Able to swim 200m continuously in any stroke - Comfortable in open water, not necessarily a strong swimmer, but at ease in water - Medical fitness declaration completed before the course starts (we'll send you the form) ## What you'll learn ### The gear - How scuba equipment works and why it works that way - Assembling your kit and running pre-dive safety checks - Understanding what your dive computer is actually telling you ### Underwater skills ![Diver hovering with arms crossed beside a vertical mooring line, looking up](https://donarundas.com/courses/recreational/open-water-diver/student-safety-stop.jpg) - Neutral buoyancy and horizontal trim, developed from your very first dive, not introduced later - Mask clearing, regulator recovery, and the other skills that matter if something goes wrong - Controlled ascents and safety stops - Buddy procedures and underwater communication ### Navigation - Basic compass navigation: rectangular patterns, reciprocal headings - Natural navigation using the reef, depth, and light ### Dive planning - Depth and bottom time: how to plan a dive and understand your no-decompression limits - Surface intervals and repetitive dives - Entry and exit techniques from shore, boat, and platform ## Course structure 5 days. Skills are practiced until they're consistent, not just demonstrated once. - **Days 1 to 2:** Pool sessions covering gear familiarity, skill development, drill repetition - **Days 2 to 5:** Open water dives, applying skills in the sea, building confidence progressively - **Maximum depth:** 18 metres - **Ratio:** 2 students per instructor maximum ## Who teaches this course Open Water courses are taught by PADI instructors personally trained and certified by Donarun. Not outsourced to a dive shop's house team. These are instructors who've gone through the same foundations-first methodology, the same standards, the same approach. If you want to train directly with Donarun, the [Advanced Open Water](https://donarundas.com/courses/recreational/advanced-diver) and [Deep Diving](https://donarundas.com/courses/recreational/deep-diving-specialty) courses are where that starts. ## Where we train The Maldives, Sri Lanka, and India. Specific location confirmed when scheduling; we'll match it to your travel plans where possible. ## What comes next Open Water gets you to 18m independently and 40m with a professional. The [Advanced Open Water](https://donarundas.com/courses/recreational/advanced-diver) course builds on that, with navigation done properly, deep dives to 30m, night diving, and 6 more dives with someone genuinely invested in your development. ## Frequently asked questions ### Do I need to be a strong swimmer? No. You need to be comfortable in open water and able to swim 200m continuously. Stroke doesn't matter; breaststroke is fine. Being relaxed in water is more relevant than swimming speed. ### Why 5 days when other courses take 3? Because 3 days is the minimum to get through the PADI checklist. Five days is how long it takes to actually develop consistent skills. The difference shows up every time you get in the water after the course. ### Will I be in the sea from day one? The first couple of sessions are in a pool or confined water for skill development. Open water dives typically start on day 2 or 3, once your foundational skills are stable. ### What depth will I reach? 18m maximum during the course. After certification, you can dive independently to 18m and to 40m with a PADI professional. ### Is this suitable for children? From age 14 as a full Open Water Diver. Younger children (10 to 11) can do the PADI Bubblemaker or Junior Open Water program.
