Does any of this sound familiar?
but no confidence in the ocean
You have the card, but you’re not sure what to actually do, and going to the ocean alone still feels scary.
and your skill hasn’t moved
You dive regularly, but nothing improves. The feeling of circling at the same level.
and further
The world beyond 30m, drysuits, ice diving, you want in, but don’t know where to start.
to dive with
You’re certified, but have no buddy to go with. You’re not sure how a diving community even forms.
now is the time to level up.
Divers who leveled up say it themselves
After Rescue Diver, the way I see every dive completely changed. The scenarios felt real, when I came out, I was a different diver.
I came for the drysuit specialty and ended up doing Rescue too. The instructors pushed me exactly as much as I needed, not a minute wasted.
The Advanced course was the most educational two days I’ve ever spent underwater. Deep, navigation, drift, all in Korean waters. Everything carried over when I dove in other countries.

Diver Essentials Program
If you have your Open Water but still lack confidence underwater, this is the answer. We train precisely what it means to truly dive well: buoyancy control, trim & balance (holding horizontal position), and fin kick technique. The skills underneath every dive, completed with video analysis and individual debriefing.
- Precision buoyancy · Horizontal trim · Body balance · Multiple fin kick techniques
- From correct gear setup to underwater movement, fundamentals rebuilt from scratch
- Video recording with individual skill analysis & debriefing (Days 1–3)
- To a level that holds its own at any dive site in the world
Includes: tuition / Not included: pool entry & equipment
Cost depends on group size and sessions.
PADI Advanced Open Water
Opens 30m. Deep dive + underwater navigation + 3 elective adventure dives. The first course to take after Open Water, and the prerequisite for Rescue Diver.
- Extends your depth limit to 30m

- Trained in real Korean conditions
Includes: tuition (2.5 days) · PADI Advanced eLearning / Not included: open water dives, gear
Cost depends on group size and sessions.
PADI Rescue Diver + EFR
The course that changes how you see diving itself. How to prevent problems, and solve them when they happen. Includes EFR first aid. The course we most often hear “why didn’t I do this sooner” about.
- First aid / CPR (EFR included)
- Real rescue scenarios
- Divemaster prerequisite
Includes: tuition (2 pool + 2 ocean days + EFR) · 3 eLearning manuals / Not included: open water dives, pool entry, gear

FAQ
I got certified abroad, can I level up in Korea?
Absolutely. PADI certifications are one global standard, and skill is evaluated the same way everywhere. If anything, training in Korea's cold water builds confidence that travels anywhere.
I haven't dived in over 2 years. Do I need to start over?
PADI ReActivate restores your skills in a single day, and you can move straight on to Advanced. There's no need to redo your full training.
Advanced or Rescue, which comes first?
Advanced is the prerequisite for Rescue Diver, so Advanced comes first. Many people take both back-to-back as a package, contact us and we'll design the schedule together.
How do I get into ice diving?
We recommend the Dry Suit Diver specialty first. Then join the waitlist, we'll contact you the moment the ice forms. January–February only, and spots go fast.
Can I take several courses in one visit?
Yes. Advanced + Rescue back-to-back is common. We'll build a schedule that fits your stay in Korea.
Can a first-time visitor start Advanced right away?
With an Open Water certification, yes, there's no minimum dive count. If your logbook is very thin, we may suggest a warm-up dive first. We'll check your current level together in a consultation.
