PADI certifications issued over 26 years at NB Divers, from your first open water to professional level. (10,000+ in-water experiences including try-dives.)
NB Divers is a PADI 5 Star CDC located in the heart of Seoul, and one of the highest-rated dive education centers in all of Korea.
“CDC” isn’t just a logo on our door. It means that every course we run, every certification we issue, and every diver we send into the water meets the strictest standards in recreational diving. It means our courses are ISO-certified. It means your PADI card from NB Divers is even recognized by universities for academic credit.
We have been operating since 2000. We hold the PADI Outstanding Service Award, 26 years, a recognition given to only a handful of centers worldwide for sustained excellence. We are an Authorized PADI TecRec Center, certified to train technical divers in deep and overhead environments.
But what we’re most proud of? Every single one of those 10,000+ divers went home safer, more confident, and more connected to the ocean than when they arrived.

NB stands for Nudibranch, the tiny, vivid sea slug that Charlie spotted clinging to a descent line on his very first dive in February 1995.
The water was 4°C. He wore a 5mm wetsuit and two layers of work gloves. He didn’t know what he was looking at. But that small white creature stopped him cold.
That moment became a philosophy. And that philosophy became NB Divers.

Charlie has been underwater for 31 years since his first dive in 1995, logging more than 6,000 dives across every environment, cold water, caves, technical depths, and open ocean.
If I had wanted to teach carelessly and hand out cards, I would have quit long ago. The same certification does not mean the same skill, the difference is in how you learned at the very beginning. So I chose training that stays with you for life, not training that just gets you done fast. That is why the person who stopped in front of a tiny sea slug in 4°C water in 1995 still gets in the water today.
“A great instructor is remembered not for their skills, but for helping people discover the happiness the ocean gives.”— Charlie Jung
NB Divers is led by a resident PADI Course Director, the highest rank in recreational diving, supported by IDC Staff Instructors, Master Scuba Diver Trainers (MSDT), and specialist instructors across technical and specialty disciplines.
Every instructor at NB Divers is personally mentored and evaluated to the same standard. You won’t find a gap between our senior staff and the person teaching your first pool session.

Fifteen years at NB Divers and still diving for the same reason she started: joyful diving is what makes life come alive. She leads our marketing and mentors new divers from their very first breath.

A patient, detail-focused instructor who guides divers from their first certification into emergency-response training, with a calm style that builds real confidence in the water.

The first face you’ll meet at NB Divers. From walk-in consultations and course booking to scheduling, she’s here to make sure every first step feels easy, even when diving is completely new to you.

A long-time member of the NB Divers community before she became an instructor, Bora knows what it means to fall in love with the water. From scuba to freediving to mermaid diving, she shares the joy of every discipline with the people who come to learn it.

We don’t just certify you and send you on your way. We think about what you’ll need after the course. What gear will actually suit you. What dive site fits your skill level right now. Where you should go next.
NB Divers limits the number of students per cohort. Instead of taking more people, we chose to give each person enough time and feedback. So before we work together, a few things you should know.
Each cohort is limited. When seats fill, you may need to wait for the next one. We’ll repay the wait with training that’s worth it.
PADI standards and safety take priority. If conditions aren’t right, we don’t push through, we find the safest path together.
Rather than cutting the price, we protect the value of the training you receive. If you’re looking for the cheapest option, there may be a better fit elsewhere.
“Learn it slow, keep it forever.”
Real skill takes time. Learn it properly once, and it stays with you for life.
“I started with zero knowledge, but every step made me proud to call myself an NB member. Having the same certification doesn’t mean the same skill level. If you want real improvement and high-quality training, this is the place.”
“Always a bridge connecting new people to new worlds. Highly recommended for anyone who needs challenge and adventure in their life.”
“NB Divers is like plankton to the ocean, the most essential first element for everything else to exist. They teach from the very beginning with care, make it genuinely enjoyable, and turn people into the best divers they can be.”
“The place that taught me what it means to truly enjoy life.”
“The ocean is open to everyone, but not everyone can enter it. With NB Divers, you can.”
“If you want high-quality training, this is it. A place overflowing with passion, where people start as Open Water divers and leave as instructors.”
“A place where diverse programs from across the diving world come together under one roof, with a team of specialists working in harmony so every diver can dive comfortably. The benchmark other dive centers look to.”
“NB Divers is the first gateway to the sea. A place where solid, trustworthy instructors are always waiting for you.”
NB Divers welcomes divers from around the world. Our team is comfortable teaching and communicating in English, and we regularly work with expats, foreign residents, and visiting divers continuing their certification in Korea.
Korea’s waters are extraordinary, and largely unknown to the international diving community. From the subtropical waters of Jeju Island to the cold, crystal-clear visibility of the East Sea in winter, this is a destination worth diving.
We’d love to show it to you.
