Sharks, Claustrophobia, and Running Out of Air: Addressing the Top 5 Fears of Learning to Dive

You’ve seen the documentaries. You’ve scrolled past the incredible underwater photos on Instagram. A part of you dreams of gliding weightlessly through a vibrant reef, surrounded by neon-colored fish and ancient sea turtles. The idea is magical.

And then… the “what ifs” begin.

“What if I feel claustrophobic?” “What if I run out of air?” “What… what about sharks?”

If this sounds like you, you are not alone. In fact, almost every confident diver you see today started with those exact same concerns. The human mind isn’t naturally designed for breathing underwater. It’s completely normal to feel a mix of excitement and anxiety.

The difference between a “what if” and “I did it” is knowledge. At 72 Aquatics, we believe the best way to overcome fear is with facts and professional training. Let’s tackle the top five fears we hear from aspiring divers right here in our Tucson shop.

Fear #1: “I’m terrified of sharks.”

This is, without a doubt, the most common fear we encounter. Decades of Hollywood movies have programmed us to see sharks as mindless monsters.

The Reality: The “Jaws” effect is a myth. Shark encounters are incredibly rare, and unprovoked attacks are even rarer. To put it in perspective, you are more likely to be injured by a cow or a vending machine.

In reality, seeing a shark on a dive is a privilege. They are majestic, intelligent, and crucial to the health of the ocean. The vast majority of shark species are completely uninterested in divers. We are large, noisy, and not on their menu. In our SSI training, we teach you to be a respectful visitor in their environment, which is all it takes to safely share the water.

Fear #2: “What if I run out of air?”

This is the most logical, scuba-specific fear. Your air tank is your lifeline, so what happens if it runs empty?

The Reality: This is one of the most avoidable problems in scuba diving, and we train for it relentlessly. Running out of air is the result of negligence, not a sudden accident.

• Your “Fuel Gauge”: You will learn to use a “Submersible Pressure Gauge” (SPG). This is your tank’s fuel gauge. A core part of your training is learning to check it constantly—it becomes a habit within your first 30 minutes.
• Redundancy (Your Buddy): You never dive alone. Your dive buddy is your built-in safety system. Every diver carries an “alternate air source” (a backup regulator) for the sole purpose of sharing air with a buddy in an emergency.
• Practice, Practice, Practice: In your very first pool session, you will practice the “out of air” scenario until it’s second nature. You’ll learn to calmly signal your buddy and use their alternate regulator. We practice it so you know exactly what to do, removing all panic from the equation.

Fear #3: “I’ll feel claustrophobic and panic.”

The idea of being deep underwater, with a mask on your face and equipment on your back, can feel constricting.

The Reality: The feeling of weightlessness is the exact opposite of being trapped. It is a feeling of total freedom, like flying. But it can take a few minutes to get used to, which is why our training starts slowly.

• We Start in a Pool: You will never be thrown into the deep end. Your first experience with scuba will be in a local pool, in water shallow enough to stand up in.
• You Are in Control: Our SSI instructors are right there with you. If you feel uncomfortable, you can simply stand up. You learn at your pace, building confidence one skill at a time.
• Mask Comfort: We spend a lot of time helping you get comfortable with your mask. We’ll teach you how to clear it if a little water gets in, so you always feel in control. This training desensitizes you to the feeling and removes the “trapped” sensation.

Fear #4: “What if my equipment fails?”

You’re relying on a regulator, a BCD, and a tank. What if one of them breaks?

The Reality: Modern scuba equipment is incredibly reliable, durable, and failsafe. It is true life-support equipment, built to exacting standards. Failures are extremely rare and are almost always preventable with proper maintenance (which our shop technicians handle for you!).

Furthermore, we train for this. You’ll learn how to manage a “free-flowing” regulator, how to recover it if it’s knocked from your mouth, and how to control your ascent even if your BCD inflator gets stuck. And, as always, your buddy is right there as your backup.

Fear #5: “I’ll get ‘the bends’ or get hurt.”

Decompression sickness, or “the bends,” sounds terrifying, as does the idea of hurting your lungs.

The Reality: These are serious-sounding conditions that are almost 100% preventable by following simple, golden rules.

• We Use Dive Computers: Gone are the days of complex tables and calculations. From your first open-water dive, you’ll use a personal dive computer. This little device does all the math for you, telling you how deep you are, how long you’ve been down, and how to ascend safely.
• The Rules are Simple: Your training will drill two rules into you: 1. Ascend slowly, and 2. Always make a safety stop. By simply following these rules and listening to your computer, you all but eliminate the risk of decompression sickness in recreational diving.

You Don’t Have to Commit to Find Out. Try It First!

Reading about safety is one thing. Experiencing it is another.

We understand that you might still be hesitant, and that’s why we offer the SSI Try Scuba program. It is the perfect, no-pressure way to see if diving is for you.

For just a small fee, you can come with us to a local pool for an evening. A 72 Aquatics SSI Professional will give you a brief orientation, help you into the gear, and then take you into the shallow water. You’ll get to take your first breaths underwater, swim around a bit, and feel the incredible sensation of weightlessness.

There’s no commitment. No classroom. Just a simple, safe, and fun way to answer all your “what ifs.” You’ll discover what thousands of divers already know: with the right training, the fear fades, and a lifetime of incredible adventure begins.
