Scuba certification is worth it for most people who plan to dive more than once. An Open Water Diver course teaches the equipment and buoyancy skills you need to dive safely, then certifies you to dive with a buddy at dive sites around the world without an instructor beside you.
Aquatic Sports has been teaching divers in Portland, Oregon, since 1966. Our SSI Open Water Diver course pairs self-paced online learning with hands-on practice in our heated indoor pool before you ever head to open water. Below, we'll walk through what the training includes, how long it takes, what it costs in 2026 and which gear is worth buying first.
What do you get from scuba certification?
You get a certification card, but the card is the least important part. What you're really paying for is structured training and supervised practice that turn breathing underwater from a novelty into a skill you can rely on. SSI Open Water Divers are certified to dive with a buddy to a maximum depth of 18 meters (60 feet), which covers a huge range of recreational dive sites.
Equipment skills
You learn how your regulator, BCD, tank, mask and fins work together, how to assemble and check your gear, and what to do if something doesn't feel right. Divers who understand their equipment are calmer in the water and make better gear choices when it's time to buy.
Buoyancy control
Good buoyancy is what makes diving feel effortless. Training gives you time to practice hovering, adjusting your BCD and using your breath to fine-tune your position, which also helps you use less air.
Communication and dive planning
You can't talk underwater, so you'll learn standard hand signals for staying in touch with your buddy. You'll also learn how to plan a dive, keep track of your air supply and stay within your depth and time limits.
Handling problems underwater
Much of the course is spent practicing responses to common situations, like clearing a flooded mask or sharing air with a buddy. The goal is to build habits you'll fall back on automatically if something unexpected happens.
How long does scuba certification take?
Most people finish Open Water Diver in a few days to a couple of weekends. Your timeline depends mostly on how quickly you complete the online portion and how pool and open water sessions fit your schedule.
The course moves through these stages:
-
Knowledge development. You learn the concepts behind diving, including equipment, dive planning and safety procedures. With SSI Digital Learning, you can work through this at your own pace. Register through Aquatic Sports and you'll get package pricing and complete your in-water training with us in Portland.
-
Confined water training. You practice core skills in a pool, where you can get comfortable breathing underwater and using your gear before the environment gets more challenging. Our heated indoor pool keeps these sessions consistent and comfortable year-round.
-
Open water training. Under instructor supervision, you show that you can apply your skills in a real dive environment. Once you complete these dives, you're certified.
How much does scuba certification cost in 2026?
In Portland, basic Open Water certification generally runs $400 to $700, while premium or private training can cost $700 to $1,000 or more. Our Portland scuba certification cost guide breaks down what drives those numbers.
When you compare courses, look past the advertised price and ask what's actually included. Costs that sometimes sit outside the base price include:
-
Learning materials and certification fees
-
Rental equipment for pool and open water sessions
-
Personal gear like a mask, fins and boots
-
Open water dive fees and travel to the dive site
-
Follow-up dives or specialty courses
A lower sticker price doesn't always mean a lower total cost, so get the full picture before you enroll.
Do you need to buy scuba gear before getting certified?
No. You don't need a full scuba setup to start training. Larger items like the BCD, regulator and tank are usually available as rental gear while you learn, so check what your course includes.
Where it does pay off is personal fit gear. A mask that seals properly on your face makes every skill easier, and fins that fit well keep your feet comfortable and your kicks efficient. Most new divers start with a mask, snorkel and fins, then add boots if they choose open-heel fins. If you're local, you can try gear in our heated pool before you buy.
Once you're certified and diving regularly, a dive gear package is an easy way to build a complete kit. Affirm and Synchrony financing can spread the cost of bigger purchases over time, and our certified scuba professionals are happy to help you pick gear that suits the diving you want to do.
Is scuba certification worth it if you only dive on vacation?
Usually, yes, especially if you expect to take more than one dive trip. Showing up already certified means you can spend your vacation diving instead of sitting in a classroom, and you can join regular guided dives rather than being limited to introductory experiences. SSI certification is recognized worldwide, so your card goes wherever you travel.
If you're only curious and not sure diving is for you, an introductory Try Scuba experience is a lower-commitment way to find out. If you already know you want to keep diving, certification gives you far more training and long-term value.
Do you need a medical clearance for scuba certification?
Before training, you'll complete a medical questionnaire. Depending on your answers, you may need a physician to sign off before you get in the water. If you have questions about asthma, heart conditions, medications or other health concerns, talk with your doctor. Divers Alert Network (DAN) is also a trusted resource for dive medicine questions.
What can you do after Open Water certification?
Open Water Diver is the start of your dive education. From there, you can build experience on local dives and trips, then add specialty courses that match your interests. Aquatic Sports offers specialties including deep diving, navigation, night and limited visibility, dry suit diving, enriched air nitrox and perfect buoyancy. Our specialty bundles and Advanced Open Water bundle package several courses together.
If you plan to dive in the Pacific Northwest, the dry suit specialty is worth putting near the top of your list. Cold water opens up some incredible diving, and our dive trips to places like Hood Canal and Campbell River, BC, give you a chance to use your new skills with an experienced group. If it's been a while since your last dive, a Scuba Skills Update is a quick way to get comfortable again.
What should you look for in a scuba certification course?
The cheapest course isn't always the best value. When you compare programs, ask about:
-
Instructor experience. Look for professionals who focus on building your skills and comfort rather than rushing you through requirements.
-
Time in the water. A strong program gives you plenty of pool practice before open water.
-
What's included. Confirm whether materials, rental gear, certification fees and open water dives are part of the price.
-
Class size. Smaller groups usually mean more individual feedback.
-
Support after certification. A dive center with specialty courses, gear help, refreshers and trips makes it easier to keep diving.
