Before You
Start
The questions every beginner asks, answered without the fluff.
Q01Do I need to be a strong swimmer to learn scuba diving?
You just need to be comfortable in the water, you don’t need to be a competitive swimmer. The PADI standard is a non-stop 200-meter swim (or 300 meters with mask, fins, and snorkel) and 10 minutes of floating or treading water. It’s not a timed test; it’s a check that you’re at ease in the water. If you can do relaxed laps in a pool, you’re fine.
Q02What is the minimum age to learn scuba diving?
From age 8, kids can experience diving through the PADI Bubblemaker program (max depth 2m). The PADI Junior Open Water Diver certification starts at age 10 with depth limits. From 15, you can earn the full unrestricted PADI Open Water Diver certification. There is no upper age limit, some of our most passionate students started diving in their 60s and 70s.
Q03I’m scared of deep water. Can I still learn?
More people than you’d think start their first lesson nervous, and leave hooked. Fear of water is human. NB’s training is designed to overcome that fear gently and step by step. You start in a pool where your feet touch the bottom, building skills and confidence before you ever see the ocean. With a maximum of 3 students per instructor, nobody rushes, there’s plenty of time to talk things through.
Q04What health conditions can affect diving?
Most healthy people can dive without issue. PADI requires a medical statement before training begins. Conditions like pneumothorax, asthma, recent surgery, or certain heart conditions may need a doctor’s sign-off. If anything concerns you, we recommend a dive medical exam before enrolling. Don’t self-diagnose, many people who worry their body isn’t built for diving find out from a doctor that they’re perfectly fine.
Q05How fit do I need to be to dive?
Scuba diving is far less physically demanding than most people expect. In the water, buoyancy carries your weight, movements become smooth, and you travel with nothing but breathing and slow fin kicks. If you can take regular short walks or do light exercise, you’re fit enough to start.
PADI
Certification
How the world’s most recognized dive certification system works.
Q01What is PADI and why does it matter?
PADI (Professional Association of Diving Instructors) is the world’s largest recreational diving membership and training organization, having certified more than 28 million divers since 1966. A PADI certification is recognized at dive sites in every country on Earth. NB Divers is a PADI 5 Star CDC, the highest rating in the PADI system, and every certification we issue carries that global standard of trust.
Q02How long does it take to get a PADI Open Water certification?
The standard PADI Open Water Diver course usually takes about 5 days, theory (self-paced eLearning & exam), 3 pool sessions, and 4 ocean dives (across two or more days).
In intensive programs, some students finish in 2 days. Speed is not the priority, mastery is.
We do not issue certifications to students who aren’t ready to dive in the ocean independently.
Q03Is a certification earned in Korea valid worldwide?
Yes. A PADI certification issued by NB Divers is valid at every PADI dive site in the world, with no expiration. Once certified, it’s for life. Palau, the Maldives, the Red Sea, your card is accepted without question.
Q04What’s the path from Open Water to Instructor?
The PADI recreational path: Open Water Diver → Advanced Open Water Diver → Rescue Diver → Master Scuba Diver (the highest recreational level) → Divemaster → Open Water Scuba Instructor → Master Scuba Diver Trainer → Course Director. Each level builds real skill and opens new diving experiences. NB Divers can take you from your first breath underwater all the way to Course Director.
Q05Can I earn a PADI certification in English at NB Divers?
Yes. All courses are available in English. Our instructors are qualified to teach in English, and all course materials, manuals, videos, and certification cards, are provided in English.
Diving in
Korea
Why Korea is one of Asia’s most underrated diving destinations.
Q01Is Korea a good place to learn diving?
Korean waters offer a varied, dramatic environment for dive training. In winter, water temperatures can drop to 2°C.
You’ll meet unique marine life that lives only in cold water.
It’s not as famous as Southeast Asia, but divers who have experienced both say Korean waters have a charm all their own.
Q02What’s the water temperature in Korea?
Temperatures vary widely by season and coast. The East Sea runs 0–5°C in winter (January–February, ice diving season) and 20–25°C in summer. The South Sea is warmer year-round. In summer (July–August) a 5mm wetsuit is enough; winter requires a drysuit. We provide all the gear you need, so there’s nothing to buy before you start.
Q03Can you dive year-round in Korea?
Yes. Korea offers excellent diving in every season, but the experience changes dramatically. Winter brings exceptional visibility (15–20m in the East Sea), ice diving opportunities, and a dramatic cold-water ecosystem. Spring and fall offer moderate temperatures and active marine life. Summer is the warmest and most accessible season for beginners. Each season has its own character and reward.
Q04What marine life can I see in Korea?
Korean waters hold surprising diversity: nudibranchs, octopus, sea urchins, large schools of fish, cuttlefish, rays, and in the East Sea, occasional large pelagics. Winter brings unique cold-water species you’ll never see in tropical diving. It’s not as famous as Southeast Asia, but for divers who’ve experienced both, Korea is often the real surprise.
Equipment
& Gear
Q01Do I need to buy equipment to learn diving?
No. NB Divers provides every piece of equipment needed for all courses, BCD, regulator, wetsuit or drysuit, mask, fins, and cylinder. You don’t need to buy anything to get certified. We do eventually recommend buying your own mask (fit and comfort matter more than any other gear), but it’s not required to start.
Q02What’s the difference between a wetsuit and a drysuit?
A wetsuit lets a thin layer of water in, which your body warms, it works well above 15°C. A drysuit seals at the wrists and neck to keep you completely dry, with an air layer and dedicated undergarments providing warmth. A drysuit is essential for Korean winter diving and strongly recommended below 12°C. NB Divers offers the PADI Dry Suit Diver certification for students who want to master this skill.
Q03Does NB Divers sell diving equipment?
Yes. As Fourth Element’s official Korean distributor, we carry the full premium line, wetsuits, drysuits, accessories, and technical gear. Fourth Element is one of the most respected brands in professional diving, known for extreme-environment performance and sustainable manufacturing. We also stock essential accessories and can advise on gear choices for your diving goals and budget.
Safety
& Standards
Q01How safe is scuba diving?
Scuba diving is a very safe activity when you’re properly trained and dive within your certification limits. Diving accidents almost always involve untrained or unqualified divers, divers exceeding their limits, or divers ignoring safety procedures. PADI training exists precisely to establish those safe limits and habits. NB Divers has maintained a zero-accident record across 10,000+ certifications since 2000.
Q02What is decompression sickness and how do I prevent it?
Decompression sickness (DCS) occurs when nitrogen absorbed during a dive forms bubbles during ascent, usually from ascending too fast or exceeding recommended depth/time limits. Prevention: follow PADI dive tables or a dive computer, ascend slowly (max 18m/min), complete a 3-minute safety stop at 5m, and dive within your certification’s depth limits. These habits are trained from your very first dive until they’re second nature.
Q03What is the buddy system and why does it matter?
Your buddy is the first person who can help in an emergency, from a simple mask leak to an out-of-air situation. At NB Divers, the buddy system is a core skill taught from your very first pool session.

Q02How many students are in a class?
Never more than 3 students per instructor.
Learning in a small group is what builds confidence and skill. This isn’t marketing copy, it’s a strict standard we keep regardless of demand. Small classes are why our students build real confidence and ability instead of just completing a syllabus.
Q03Are classes available in English?
Yes. We offer full courses in English year-round and regularly work with international students and foreign residents. All materials are provided in English, and our instructors hold PADI qualifications for teaching in English. We never drop international students into a Korean class and expect them to keep up.
Q04How do I sign up for a course?
The easiest way is to message us directly by email or phone. Tell us your goals, current experience level, and schedule, and we’ll recommend the right course and timing. We don’t use an automated booking system, every student talks to an instructor before enrolling. Contact: mail@nbdivers.com or +82 10-8852-5185.
