Open Water vs Advanced: Which Certification Is Right for You?

Getting into diving and torn between Open Water and Advanced Open Water? I get this question almost every week. Short answer: it depends on your experience and your goals. Long answer is below.

What is the PADI Open Water certification?

The PADI Open Water Diver is the first scuba certification. It's the starting point for anyone who has never dived (or who did a discovery dive and wants to go further). No prerequisites, available from age 10.

What you learn

• Diving fundamentals: breathing, buoyancy, underwater communication
• Essential safety procedures
• Equipment management
• 4 supervised open water dives

Key numbers

By the end, you are a certified diver. You can dive anywhere in the world with a buddy, down to 18 metres. That is already huge , 18 metres is where the majority of marine life is found on most dive sites.

What does the Advanced Open Water certification offer?

The PADI Advanced Open Water is the natural next step. Prerequisite: Open Water certification (or equivalent). You can even do it right after your Open Water during the same trip.

What you learn

• Deep diving (up to 30m): nitrogen narcosis management, planning
• Underwater compass navigation
• 3 adventure dives of your choice: night, wrecks, buoyancy, photography, naturalist...

Key numbers

The big difference: the Advanced is much more practice-oriented. No formal written exam, no lengthy pool sessions. Everything happens in the sea. It's the "fun" part of diving, where every immersion is a discovery.

So, which one should you choose?

Choose Open Water if...

• You have never dived before (or just did a discovery dive)
• You want your first globally recognized certification
• You want to be able to dive independently with a buddy

Choose Advanced if...

• You are already Open Water certified
• You want access to deeper sites (many wrecks and walls are between 20 and 30m)
• You want to try night diving, navigation, or wreck exploration
• You are thinking about continuing toward Rescue Diver or Divemaster

The winning combo

My advice? If you have the time and budget, do both during the same dive trip. That is what many of our students do: Open Water for 4 days, then Advanced for 2-3 days. In one week, you go from zero experience to certified diver down to 30 metres. That is exactly the idea behind our "From zero to 40m in 12 days" package.

Frequently asked questions

Can I do the Advanced right after Open Water?

Yes, absolutely. Many divers do both back to back. There is no minimum number of dives required between the two certifications.

Is the Advanced harder?

Not really "harder" , it is different. There is no formal exam. Learning happens in the water, dive after dive. It is more exploration than testing.

Is 18 metres enough?

Honestly, yes and no. 18 metres is already enough to discover beautiful reefs, tropical fish, and even some wrecks. But if you want to see the big drop-offs, deep wrecks, or dive at night, the jump to 30 metres changes everything.
