How to Learn Scuba Diving: Step-by-Step for Beginners

Scuba diving is your gateway to an incredible world beneath the water. If you want to learn how to scuba dive, it can feel overwhelming at first. Everyone is nervous, uncertain, and at some level of scared the first dozen times they go underwater on compressed gas. Yes… even me.
I grew up around water, played water polo, and had no problem getting splashed in the face, holding my breath, or diving down deep. But when I started scuba, I quickly realized that breathing underwater is an entirely different experience. It’s not natural, and that’s okay. If you need more time or multiple attempts at a skill to feel comfortable, that’s completely normal.
If you’re feeling nervous or unsure...just know that’s part of the learning process. Scuba diving is about taking it one step at a time, building confidence, and enjoying the adventure. Let’s get started!
Common Questions About Learning to Scuba Dive
Most people complete their Open Water certification in 3 to 4 days, depending on the course structure. Some dive shops offer weekend-intensive courses, while others spread the training over multiple weeks with evening sessions. Expect to spend time on eLearning, confined water skills, and open water dives.
The cost of Open Water certification varies by location and training agency. In the U.S., expect to pay between $400 and $800 for the full course. This often includes instruction, rental gear, pool sessions, and certification fees. Some shops also require personal gear like a mask, snorkel, and fins, which may be an additional cost.
Yes, you do need basic swimming skills. Most certification agencies require a swim test (usually 200 meters) and a 10-minute float or tread. You don’t need to be a strong swimmer or have perfect form, just comfortable in the water without assistance.
Most agencies allow children as young as 10 to begin scuba training, though some programs for 8–9 year olds offer limited depth and supervision. There is no upper age limit as long as you are medically fit to dive. Many divers start in their 40s, 50s, or beyond.
Yes — with proper instruction and supervision, scuba diving is a very safe activity. Beginner courses focus heavily on safety skills, emergency procedures, and how to avoid common risks. Most incidents happen when divers rush, skip training, or dive beyond their limits. Good training and solid habits make all the difference.
Steps to Get Started

Step 1 - Choose a Dive Shop
Choose a dive shop that values safety, quality instruction, and respect over sales. Visit, ask questions, and trust professionalism over proximity.

Step 2 - Choose a Dive Instructor
Choose an instructor who can communicate clearly, emphasizes buoyancy, and adapts to your learning pace for lasting dive confidence.

Step 3 - Try Discover Scuba
A Discover Scuba dive lets beginners safely try scuba in shallow water with an instructor. It’s guided, fun, and not a certification.

Step 5 - Buy Basic Gear
