Step 7: Better Control and Its Effects on Confidence

Step 7 of 10 Steps to Boost Confidence, Dive Safely, and Empower Nervous Divers

We’ve made significant progress and taken amazing steps towards becoming Comfortable, Capable Rockstar Divers! Over the past few weeks, we’ve talked about improving confidence through better communication, understanding your gear, and developing solid situational awareness. Now it’s time to shift our focus to something a bit more physical — control.

Control in diving means knowing how to position your body, adjust your buoyancy, and move efficiently through the water. When you have control over these elements, your confidence skyrockets because you aren’t wasting energy or fighting to stay in position — you’re simply diving.

Better control is what separates a calm, effortless dive from one where you feel like you’re constantly adjusting and correcting. And the great news? It’s not complicated — it’s just about understanding the mechanics of how your body, breath, and gear work together underwater.

Why Better Control Builds Confidence

Feeling in control underwater removes the guesswork from your dives. Instead of constantly wondering if you’re going to float up, sink down, or crash into the reef, you can focus on what really matters — enjoying the dive and exploring the underwater world.

Here’s how control boosts confidence:

✅ Less Stress – Knowing you can stay at a specific depth without fighting for it keeps your heart rate down and your mind calm.

✅ Improved Air Consumption – Less effort = less air used = longer dives.

✅ Better Focus – When you aren’t fighting for control, you can focus on your surroundings and enjoy the dive.

✅ Safety Boost – Confident control means you’re better prepared to handle changing conditions like current or surge.

When you feel like you’re in control, you stop “getting through” the dive — you start owning it.

Key Elements of Better Control

Better control underwater comes down to four key factors: buoyancy, trim, finning, and breathing.

1. Buoyancy Control

Buoyancy is the foundation of control. When you master it, you’ll feel like you’re weightless and gliding effortlessly through the water.

• Use small adjustments with your BCD instead of big inflations/deflations.

• Fine-tune with your breathing — inhale to rise, exhale to sink.

• Practice hovering in place without sculling with your hands or feet.

👉 Think of your BCD as a fine-tuning tool — not a lift bag.

A diver should maneuver skillfully around the reef, enjoying thier tranquil journey surrounded by marine life. Buoyancy awareness coupled with correct body position is what makes this possible.

2. Trim and Positioning

Trim is all about how your body is positioned in the water. A good, horizontal trim makes you streamlined, reduces drag, and allows you to move more efficiently.

• Keep your weights balanced — too much weight at the back or front throws off your trim.

• Adjust your gear positioning so your body naturally stays level.

• Keep your fins slightly above your body line to avoid “fin drag.”

👉 A well-trimmed diver looks relaxed — because they are.

3. Kick Techniques

Not all kicks are created equal — different techniques are useful for different situations:

• Frog Kick – Great for maintaining position and moving slowly without stirring up sediment.

• Flutter Kick – More powerful, good for swimming into current but can cause more drag.

• Modified Flutter – A slower, more relaxed version of the flutter kick that’s great for maintaining pace.

👉 Your goal is efficiency — move as little as possible to get where you need to go. I would also encourage you to learn to cut out all unnecessary movements underwater. Do you use your hands? Are your fins causing unnecessary drag during a part of your kick? Don't be ashamed if you do, but knowing that you do these things is the first step to correcting the problem.

4. Breathing Rhythm

Breathing isn’t just about air consumption — it’s a key part of buoyancy and control.

• Deep, slow breaths help keep you calm and improve buoyancy.

• Inhale = rise slightly; exhale = sink slightly.

• The slower you change the volume of air in your lungs, the more control you will ultimately have.

• A steady breathing rhythm prevents overexertion and CO2 buildup.

👉 Control your breath, control your dive.

A Story from the Field

Let me tell you about a diver who learned the hard way how much positioning matters in a current…

We were diving at a beautiful site with a mild but steady current running along the reef. For those who don’t know, the

current is significantly lighter the closer you are to the bottom because the reef itself provides some natural protection and reduces the flow.

Most of us were hanging low near the bottom, comfortably cruising along with the current. But one diver — let’s call her Sarah — was struggling. She was hovering way up above the rest of us, like a kite above the treeline. The problem was that the current was much stronger up there, and since Sarah hadn’t quite mastered her body positioning, she was getting pushed around.

Sarah didn’t want to drop down closer to the reef because she was nervous about hitting the coral or losing control — which is understandable — but it meant that she had to kick like crazy just to keep up with the group.

By the 20-minute mark, she was exhausted. She’d burned through most of her tank trying to fight the current, and her buddy was not thrilled when they had to call the dive early so she could surface. He’d tried signaling to her multiple times to come down and take advantage of the calmer current closer to the bottom, but she either didn’t see him or didn’t feel comfortable dropping down.

Sarah surfaced with less than 500 psi left — and a valuable lesson about how body positioning and current control go hand in hand.

Common Mistakes and How to Fix Them

🚫 Overweighting or Underweighting – Causes constant inflating/deflating of the BCD, leading to wasted energy.

✔️ Solution: Do a proper weight check before every dive.

🚫 Finning Too Much – Kicking constantly throws off buoyancy and burns through the air.

✔️ Solution: Trust your buoyancy and let your fins glide more often.

🚫 Holding Your Breath – Causes unexpected buoyancy shifts and increased stress.

✔️ Solution: Keep your breathing slow and steady.

Weekly Challenges

Challenge 1: 🖐️ “The Hand in the Car Window”

Next time you’re in a car, stick your hand out the window. Remember how you can make it rise and fall by changing the angle? The same principle applies underwater when you’re swimming into a current — head up = rise, head down = sink. Experiment with this next time you’re in the water to use the current to your advantage!

Challenge 2: 🦵 “Finning Techniques 101”

There are countless videos online that go over different finning techniques. Watch a few and see if you can spot the differences between a frog kick and a flutter kick. Notice how each one affects your movement and energy use in the water. Try to practice both on your next dive and see which one feels more natural.

Challenge 3: ✍️ "Kick Inventory"

On a piece of paper, write down which kick you use the most. When and why is it most beneficial? Maybe your instructor just never taught you another way? Based on your video research, which other kicks would be useful to learn, and in what situations? Think about your dive guides when you travel — how do they kick? Do you have videos from past trips you can watch to compare your style to those of experienced divers?

Final Thoughts

Better control is one of the fastest ways to transform your diving experience. When you can hover effortlessly, adjust your depth with your breath, and glide through the water without overworking, confidence follows naturally. The best part? This isn’t about complicated skills or expensive gear — it’s about fine-tuning the things you’re already doing. Smalladjustments lead to big improvements.
