Your Ultimate Guide to Choosing a Diving Certification
Confused between PADI, SSI, CMAS, RAID or SDI/TDI? This guide explains how diving organizations differ, what really matters when you pick a course, and how to choose the right path for your underwater journey.
Quick answers about which diving organization and certification to choose.
⚖️ Fast Answers — Which Agency?
- PADI: Largest global presence, very easy to find anywhere you travel.
- SSI: Flexible and digital, strong where SSI centres are available.
- CMAS: Very solid & traditional, especially strong in Europe.
- RAID / SDI-TDI: Great for advanced and technical divers.
- Key point: Your dive centre & instructor matter more than the logo.
🏫 Fast Answers — What Really Matters?
- Small groups (ideally max 1 instructor : 4 students).
- Modern, well-maintained equipment.
- Experienced, patient instructors who take time with skills.
- Good reviews and transparent safety culture.
- Clear explanation of what is included (and what isn’t).
Why Your Choice of Dive Destination and Center Matters
Before comparing PADI, SSI, CMAS or other logos, focus on where and with whom you’ll actually learn to dive.
Most major diving organizations follow recognised safety standards, so your course content will cover similar core skills everywhere: equipment use, buoyancy, safety procedures, buddy checks, and basic navigation.
What changes dramatically from one place to another is the experience in the water: group sizes, time spent on each skill, the condition of the equipment, and how confident you feel at the end of the course.
Key factors to consider when choosing a dive center
- 📍 Location: Are you close to safe, interesting dive sites suitable for your level?
- 🛠️ Equipment quality: Is the gear modern, well-maintained and regularly serviced?
- 👩🏫 Instructor experience: Do they have a solid teaching background, not just a few certifications?
- 🌟 Reviews: Check recent online reviews for comments on safety, atmosphere and organization.
Important Note: Beware of “Too Good to Be True” Prices
Choosing a diving course only because it is the cheapest can look attractive on paper, but often hides compromises that directly impact your safety and enjoyment:
- 📉 Rushed or insufficient training: Skills are skipped or done too quickly.
- ⚠️ Old or poorly maintained gear: Increases the risk of equipment issues underwater.
- 👩🏭 Overworked instructors: “Factory-style” centres push staff to certify as many divers as possible.
- 🎭 Loss of the spirit of diving: When everything is about volume, the relaxed, fun spirit disappears.
Diving Organizations and Certifications: A Global Overview
From PADI to CMAS, all serious agencies share the same goal: make you a safe, confident diver. The way they teach, brand and structure courses, however, can differ.
International vs Local Organizations
Some agencies are truly global, with centres almost everywhere you can dive, while others are more regional or specialised:
- PADI & SSI: Widely present worldwide, very easy to continue your training when you travel.
- CMAS: Strong historic presence, especially across Europe and many local federations.
- RAID, SDI/TDI, GUE: Often more focused on advanced and technical diving paths.
All reputable agencies follow recognised safety frameworks such as those from the Recreational Scuba Training Council (RSTC) or equivalent bodies, which ensures a common minimum standard.
What You Learn Is Very Similar Everywhere
Regardless of the logo on your card, all entry-level scuba courses teach the same essential skills:
- 🤿 How to assemble, check and use your equipment correctly.
- ⚓ Safety protocols, buddy procedures and emergency responses.
- 📍 Buoyancy control, basic navigation and protecting the environment.
Where agencies differ most is in course structure, teaching philosophy, materials (books vs fully digital), and how easy it is to continue with them as you progress.

How to Choose the Right Organization
- 🎯 Identify your goals: Purely recreational holidays? Or long-term, professional or technical ambitions?
- 📍 Consider your location: Choose an agency with strong representation where you live and where you plan to dive.
- 💸 Evaluate costs carefully: Cheap is not always bad, expensive is not always good — look at value, safety and support.
- 🔁 Think about continuity: Will it be easy to keep training at higher levels or in other countries with this agency?
Zoom on Major Diving Organizations
A quick look at what makes each agency unique — and who they are best suited for.
PADI (Professional Association of Diving Instructors)
PADI, founded in 1967 in the USA, is the largest diving organization in the world. Around 70% of divers are certified through PADI. Courses are standardized and available almost everywhere.
- ✅ Pros: Worldwide presence, structured training path, strong eLearning program.
- ❌ Cons: Sometimes a bit more expensive depending on the region.
- 🏆 Best for: Beginners and travellers who want a certification recognized practically everywhere.
SSI (Scuba Schools International)
SSI, created in the 1970s, offers very flexible training and strong digital tools, often through dedicated apps.
- ✅ Pros: Modern digital materials, good value in many areas, focus on instructor–student relationship.
- ❌ Cons: You are limited to dive centres that are officially SSI-authorised.
- 🏆 Best for: Recreational divers who like app-based learning and plan to stay near SSI centres.
CMAS (Confédération Mondiale des Activités Subaquatiques)
CMAS was founded in 1959 and counts Jacques Cousteau among its founders. It has a strong tradition and is very present in European diving clubs and federations.
- ✅ Pros: Robust training standards, strong club culture, continuity across national federations.
- ❌ Cons: Less visible in some tourist destinations outside Europe.
- 🏆 Best for: Divers who enjoy club environments or who are interested in deeper/technical paths via federations.
RAID & Technical Diving Agencies
RAID, SDI/TDI and GUE are very well regarded for advanced and technical diving such as deep, cave and mixed-gas training.
| 🔧 Organization | 📜 Specialty | 🌟 Key Strength |
|---|---|---|
| PADI TecRec | Technical diving (deep, decompression). | Global network, pathways from recreational PADI levels. |
| TDI/SDI | Mixed-gas, cave and technical diving. | Very comprehensive technical programs. |
| GUE | Expedition, exploration and conservation-focused diving. | Strong emphasis on teamwork, standardization and safety. |
The Instructor Matters More Than the Logo
You don’t dive with a logo — you dive with a person. Your instructor will shape your first experiences underwater far more than the agency brand.
A passionate, experienced instructor makes the difference between “just getting a card” and truly feeling comfortable underwater. When you evaluate a dive centre, don’t hesitate to ask direct questions.
What to ask your future instructor
- 📜 Experience: How long have they been teaching? How many certifications have they issued at your level?
- 🗣️ Communication: Do you feel comfortable asking questions and expressing fears?
- 🌟 Student feedback: Are there reviews mentioning them by name?
- 👥 Group size: Will they teach you in a small group or in a big “factory” class?
Red Flags to Watch Out For
- Very short course durations with little time in the water.
- Gear that looks very old or poorly maintained.
- Instructors juggling too many students at once.
- Pressure to “hurry up” or skip skills instead of repeating them until you are comfortable.

FAQs — Choosing a Diving Certification
Is one agency “better” than all the others?
No single agency is perfect for everyone. PADI, SSI, CMAS, RAID, SDI/TDI and others all produce safe, competent divers. The dive centre and instructor you choose have far more impact on your experience than the brand alone.
Will I be able to dive everywhere with a PADI or SSI card?
Yes, in most destinations a recognised certification from PADI, SSI, CMAS, RAID or SDI/TDI is accepted as long as your level matches the dive conditions (depth, currents, environment). Always be honest about your experience.
Can I start with one organization and continue with another?
Usually yes. Many dive centres accept certifications from other agencies as prerequisites. At higher or technical levels, some extra training or “bridging” may be required, but for recreational levels, switching is common.
How important is price when choosing a diving course?
Price matters, but quality and safety come first. Very low prices can hide compromises on equipment, time in the water and instructor availability. Look for a fair price with small groups, good equipment and excellent feedback.
What is the best first course to become a certified diver?
Most agencies offer a course equivalent to PADI Open Water Diver as the entry-level certification. It allows you to dive to 18 m with a buddy in conditions similar to your training. Contact us and we’ll explain the options based on your plans.
Can I do my professional training (Divemaster or Instructor) in Komodo?
Yes. As a PADI 5★ IDC Centre, Dragon Dive Komodo offers Divemaster and Instructor Development Courses in real-world conditions with mantas, currents and varied sites — perfect to become a strong dive professional.
