Don't worry, we're not just trying to sell you a course; we're trying to fill your confidence tank. After reading this, you'll be ready to dive into that blue dream. Here are the 15 most common questions about learning to scuba dive... and our answers!
1. Is scuba diving safe?
SCUBA DIVING FAQs
Yes! Decades of research have gone into scuba diving and how to make it as safe as possible. Dive courses are designed to teach you everything you need to know about diving safely. This includes how to avoid running low on air, checking your air regularly, ascending slowly and safely to avoid decompression sickness, and planning your dives to ensure safety.
Scuba diving (like most activities) has some inherent risks, but when divers follow the rules they are taught, it is an extremely safe activity. Statistically, you are far more likely to be injured while driving a car. The key is to listen to your instructor and dive within your limits.
2. Is scuba diving hard to learn?
SCUBA DIVING FAQs
Scuba courses are designed to teach you everything you need to know in just a few days, and it's all easy to remember. There’s always more to learn in diving, but mastering the basics is surprisingly easy—and a lot of fun! Once you practice using the equipment and learn skills like buoyancy control, you'll find it doesn't take much thought, and scuba diving becomes second nature. That first hurdle of breathing underwater feels strange for a minute, then amazing!
3. What is a scuba diving certification?
SCUBA DIVING FAQs
You get certified after you pass all the requirements in your scuba diving course. The best way to learn to scuba dive is by getting your Open Water Diver certification, which will qualify you to dive safely to a maximum depth of 18 meters (60 feet). Once you have this certification, you can present it at any dive center around the world and start exploring. But getting your Open Water Diver certification is just the beginning!
There are many advanced diver programs you can take that will certify you to dive deeper, go wreck diving, try night diving, and much more. Your certification card is your "underwater passport"—it's recognized globally.
4. Does a scuba certification expire?
SCUBA DIVING FAQs
Once you are certified, you are certified for life! However, if you have not been scuba diving for a while (usually 6-12 months), you will be required to take a Scuba Skills Update (or "refresher") with a dive professional. They can assess your dive skills and ensure you still feel comfortable in the water. Think of it as a quick check-up to stay fresh and safe.
5. How deep can you scuba dive?
SCUBA DIVING FAQs
The maximum depth for recreational scuba diving is 40 meters (130 feet). Technical divers can go much deeper, but this requires extensive, specialized training and breathing different gas mixtures. As a beginner, you'll start with a limit of 18 meters (60 feet), which is where you'll find the most vibrant coral reefs and marine life. Depth isn't a competition; it's a boundary for safety.
6. How old do you have to be to scuba dive?
SCUBA DIVING FAQs
The minimum age to learn to scuba dive and get an Open Water Diver certification is ten years old. However, the SSI Explorers program offers options for kids as young as six to experience diving and snorkeling in very shallow water. There is no upper age limit, as long as you are in good health! Scuba diving is a fantastic activity for the whole family.
7. Can I scuba dive if I wear glasses?
SCUBA DIVING FAQs
You cannot dive with your glasses on, as they will not fit under your mask and will prevent it from sealing. However, you can absolutely dive with contact lenses, or you can even buy a prescription dive mask. Most SSI centers stock them or can order them for you. Don't let your vision stop you—the underwater world is too beautiful to be blurry!
And while a prescription mask clears up *your* view, using a DIVEVOLK professional housing for your smartphone ensures your *camera* gets a perfect, clear view, too, protecting your device while you capture the stunning underwater world in high definition.
8. How much does it cost to learn to scuba dive?
SCUBA DIVING FAQs
The price varies depending on your location. For example, learning to dive in Southeast Asia is often cheaper than in Europe or the USA due to lower living costs. The best thing to do is decide where you want to learn, then use the SSI Center Locator to find dive centers in that area and contact them for prices. An entry-level course typically runs from $300 to $600, which almost always includes your gear rental.
9. What gear do I need for scuba diving?
SCUBA DIVING FAQs
Don't panic—you don't need to buy everything at once! Your basic scuba gear includes: a mask (to see), a regulator (to breathe), a BCD (Buoyancy Control Device, a vest that helps you float or sink), fins (to swim), and a tank (your air source). Your SSI course will include the rental of all this equipment. After your course, you can decide what to buy first (most people start with a mask and fins).
Premium Gear Pick: Capture Your Dives
While your course covers the life-support basics, many new divers want to capture their first breaths underwater. For this, we recommend the DIVEVOLK Seatouch 4 Max housing. It provides professional-grade, waterproof protection for your smartphone, allowing you to use your phone's amazing camera at depth. It's the perfect way to bring back memories without investing in a separate, expensive camera rig right away.
10. Should I worry about sharks?
SCUBA DIVING FAQs
The media has given sharks a bad rap. In most dive locations, they are rarely seen by divers, and even when they are, they typically avoid divers or ignore them completely. We are not on their menu. However (as with any wild animal), you should always show respect. If you are afraid of seeing sharks, you can research which areas of the world are less likely to have them and dive there. The truth is, a shark sighting is a rare privilege, not a threat.
When filming with a DIVEVOLK housing, you can safely document these magnificent creatures from a respectful distance, showing the world they are to be admired, not feared.
11. Do I have to sign up for a full course if I'm not sure I'll like it?
SCUBA DIVING FAQs
Nope! You can start with an SSI Try Scuba program (often called a Discover Scuba Dive). This program lets you experience scuba diving without committing to a full certification course. Your instructor will introduce the gear, teach you basic safety, and stay right with you as you take your first breaths underwater. This dive is always done in shallow water (less than 12 meters/40 feet). If you love it, you can then sign up for the Open Water Diver program.
12. What should I expect from the Open Water Diver course?
SCUBA DIVING FAQs
The Open Water Diver course has three parts: Academics (theory, often done online), Confined Water (practicing skills in a pool or calm, shallow water), and Open Water Dives (dives in a lake or ocean, deeper than 5 meters/16 feet). You'll learn vital safety rules, how to be an independent diver (like checking your own air), and valuable practical skills like hovering weightlessly (neutral buoyancy). The course usually takes 3-4 days and is a ton of fun.
13. How do I relieve ear pain when diving?
SCUBA DIVING FAQs
This is a very common worry! But your instructor will teach you how to "equalize" the pressure you feel in your ears as you descend. After a little practice, you'll do it naturally. The most common methods are pinching your nose and gently blowing (the "Valsalva Maneuver") or simply swallowing. Pitfall to avoid: Equalize early and often. Don't wait for pain, and never force it. If you have a cold, you should not dive.
Pro-Tip: Handling Your Gear
Just like equalizing your ears becomes second nature, so does handling your gear. When you're ready to start filming, you want technology that feels just as intuitive. Using a DIVEVOLK housing is simple: the full-screen touchscreen access means you use your phone just like you do on the surface. There's no new button layout to learn, so you can focus on your dive and get the shot, not on the gear.
14. How do I communicate underwater?
SCUBA DIVING FAQs
No sound? No problem! We use a set of standard hand signals. This is your "underwater language." You'll learn the "OK" signal (thumb and forefinger in a circle), "Problem" (waving your hand), and "Go Up" (thumb up). Your SSI course will teach you about 10 core signals to ensure you and your buddy are always on the same page. It's not just for safety; it's for fun, too—like pointing out an amazing fish!
15. Do I need to be physically fit to scuba dive?
SCUBA DIVING FAQs
You do not need to be a super-athlete. People of all fitness levels can enjoy scuba diving. It doesn't take much strength to carry your gear (in short bursts) or swim in the water. However, you should be able to swim and comfortably tread water. Before your course, you will be required to fill out a medical questionnaire. If you have any pre-existing health conditions, you must get a doctor's approval to ensure you are safe to dive. Remember: scuba is an inclusive sport, not a marathon.
We hope we've answered your biggest questions and that you're feeling more confident about learning to dive! These Q&As aren't the end; they're the beginning. Head over to the SSI website, find your nearest dive center, and book a Try Scuba session.
