PADI vs SSI vs NAUI: which certification you actually need
PADI, SSI, NAUI and SDI are all internationally recognised, and no agency's card is inherently "better" — your instructor and your logged practice determine your competence, not the logo. PADI and SSI shops are the most common here.
- Discover Scuba Diving — not a certification, just one supervised dive to find out whether you enjoy it. Do this before booking a multi-day course
- Open Water Diver (OW) — the entry-level certification: theory, confined water skills, and open water dives, after which you can dive with a buddy within set limits
- Advanced Open Water (AOW) — adventure dives including deep and navigation, extending your depth limit and skills
- EFR / Rescue Diver — handling problems and emergencies, widely considered the most worthwhile course anyone takes
- Specialties — wreck, night, nitrox, underwater photography
One piece of advice new divers ignore: do not roll straight from OW into AOW. Log a dozen dives and get your buoyancy solid first — the AOW course teaches you far more when you are not still fighting your trim. Package deals combining both are cheap for a reason.
Where the money goes
Course prices vary widely by location — resort destinations such as Boracay and Mactan generally run higher than dive-focused towns like Anilao, Puerto Galera or Moalboal — and instruction in a less common language usually costs a tier more. Ask for an itemised written quote covering:
- Course fee — instructor time, confined and open water dives, rental gear, tanks and weights. Confirm whether learning materials or the online account are extra
- Certification fee paid to the agency, frequently listed separately and easily overlooked
- Boat fees and environmental or municipal fees, usually per day or per trip
- Accommodation and meals — course-plus-stay packages are often better value, but check the room type and what meals are included
- Transport — domestic flights, transfers, ferries and bangka rides. Reaching Anilao or Puerto Galera from Manila is a real line item
- Dive insurance, which is never included and which you should buy
- Medical clearance if your health declaration requires a physician's sign-off
- Tips for boat crew and instructors — customary here, so budget a little
Sensible savings: travel outside peak season and holidays, book as a small group for a discount, bring your own mask and snorkel (fit matters and it is the cheapest gear to own), and bundle course with accommodation. Never economise on insurance, on the student-to-instructor ratio, or on the condition of tanks and regulators.
How many days to allow — including the flying rule
- OW — realistically three to four days. Complete the theory online before you fly; that is the only part worth compressing. Treat any "certified in two days regardless" offer as a warning, because what gets cut is skill practice
- AOW — around two days
- EFR plus Rescue — around three to four days
- Add a buffer day. Weather, sea state, ear-clearing problems or feeling unwell can cost you a day, and a tight schedule creates pressure to dive when you should not — which is precisely how incidents happen
The constraint nearly every beginner overlooks: you cannot fly immediately after diving. Common guidance is a minimum of 12 hours after a single no-decompression dive and 18 hours or more after repetitive or multi-day diving, with many operators recommending a full 24. Follow your training agency's current guidance and your instructor, and build the interval into your flight booking rather than discovering it on the last morning.
Seasonally, most Philippine sites are diveable year-round but monsoons matter: the northeast Amihan (roughly November to February or March) and the southwest Habagat (roughly June to September or October) affect different coasts differently, and typhoon activity concentrates in the second half of the year. Check typical conditions for your chosen area and month rather than relying on photographs.

Vetting a dive shop: the safety checklist
- Verify the shop and the individual instructor on the certifying agency's official lookup, and check the status is current. A logo on the door proves nothing
- Ask the student-to-instructor ratio in writing. Industry maximums exist, but good shops voluntarily run well below them. An instructor with six or seven new divers cannot watch you closely
- Inspect the gear. Regulator and BCD servicing records, visible tank inspection and hydrostatic test dates, and rental BCDs in a range of sizes — a badly fitting BCD ruins a course
- Check the safety setup. Emergency oxygen and a first aid kit on the boat, descent lines and surface marker buoys, headcounts by the crew, and a stated lost-diver procedure. Ask directly: where is the nearest hyperbaric chamber? A shop that knows the answer takes safety seriously
- Watch the teaching. A proper course includes full skill work — mask clearing, regulator recovery, buoyancy, controlled ascents. If an instructor waves that away, leave
- Language. You must understand every safety instruction completely. If English is a struggle, pay for an instructor in your own language
- Read reviews for substance — comments about briefings and safety procedures tell you more than praise for the scenery
Hard stops: shops that promise certification regardless of performance, that suggest you tick "no" on the health declaration for convenience, that skip confined-water practice, that carry no oxygen on the boat, or that take only cash and produce no paperwork. Walk away and write off the deposit.
Safety lines you never cross
Every line below is one that good shops hold and bad shops quietly bend — if an instructor waves any of them away, that alone is enough reason to walk.
Non-negotiables, regardless of what anyone tells you: complete the medical declaration honestly — asthma, cardiac conditions, epilepsy, diabetes, recent surgery, ear and sinus problems, pregnancy and certain medications may require a physician's clearance. Never dive with a cold or blocked ears; forcing equalisation causes some of the most common diving injuries. No alcohol before diving, and go easy the night before, since dehydration raises decompression risk. Control your ascent rate and do the safety stop. Always dive with a buddy after a full pre-dive check. Never exceed your training — no wreck penetration or overhead environments you have not been trained for, which matters here because the wrecks are tempting. Use a dive computer. And buy dive-specific insurance: standard travel policies typically exclude scuba, hyperbaric treatment and evacuation are expensive, and chambers in the Philippines are limited and unevenly distributed. If you feel dizzy, achy, numb, unusually tired or develop a rash after diving, do not sleep it off — contact your instructor and seek medical help immediately.
Where to learn, and how to fit it into the trip
Pick the region for its diving conditions and your travel dates, then pick the shop for its instructor — in that order.
On location: Anilao is closest to Manila by road and dense with sites; Puerto Galera is the classic budget-friendly certification base; Moalboal offers easy shore diving, which means cheap extra practice; Bohol and Panglao suit travellers bringing family; Coron and El Nido are spectacular but wreck penetration is an advanced pursuit and costs run higher; Malapascua and its thresher sharks suit certified divers rather than students. Where you certify matters far less than who teaches you — pay a little more for an instructor willing to run your buoyancy drill a third time.
If the course is one piece of a longer Philippine trip and you would rather not stitch together visas, domestic transport, accommodation and the non-diving days yourself, you can have Yixing plan the whole itinerary. We will match the region to your dates and the season and flag which days may be blown out — the course itself you contract directly with a certified dive shop; we make no promises on any shop's behalf.
