Why Can't I Stay Still Underwater? How to Master Your Scuba Hover

You've added the right amount of air to your BCD. You're not sinking.

You're not floating toward the surface. Everything feels good.Then you stop kicking.

Suddenly your feet start dropping, you begin drifting downward, your hands start moving, and within a few seconds you're making corrections again.

Sound familiar?

Being able to establish neutral buoyancy and being able to remain completely still underwater aren't necessarily the same thing. Hovering exposes all the little corrections we make without realizing it. Take away the kicking and hand movement, and suddenly you discover whether you're actually controlling your position—or whether movement has been doing some of the work for you. That's why hovering is such a valuable skill to practice.

Neutral Buoyancy Is Only Part of the Equation

Neutral buoyancy means you're neither positively nor negatively buoyant. But that doesn't automatically mean you're balanced. You can be neutrally buoyant while your feet are sinking. You can be neutrally buoyant while slightly head-down. You can even be neutrally buoyant while constantly sculling with your hands or fins. The goal isn't simply to stop rising or sinking. It's to become comfortable enough that you can stop moving and maintain your position with minimal effort. That's where buoyancy, trim, breathing, weighting, and body awareness all start working together.

First, Stop Moving

One of the easiest ways to evaluate your buoyancy is also one of the hardest things for many divers to do:

• Stop.

• Stop kicking.

• Stop moving your hands.

• Stop making constant BCD adjustments.

• Give yourself a few seconds and see what happens.

• Do you slowly sink?

• Do you rise?

• Do your legs drop?

• Does your upper body rotate?

You may learn more about your diving in ten seconds of doing absolutely nothing than you will during several minutes of swimming. Movement can hide a lot of small problems.

Once you stop moving, those problems become much easier to identify.

Your Breathing Is Part of Your Buoyancy Control

Your lungs aren't just keeping you alive underwater. They're also part of your buoyancy system. Take a deeper breath and you'll usually begin to rise slightly. Exhale and you'll begin to settle. Experienced divers use these small changes naturally to make minor adjustments without reaching for their BCD inflator every few seconds. The important word here is minor. Your lungs aren't a replacement for proper weighting or BCD control, and you should never hold your breath while scuba diving. But once your basic buoyancy is established, relaxed breathing can help you make very subtle changes in position.

Learning that relationship takes practice. Eventually, you stop thinking about it.

Give Your BCD Time to Work

Another common problem is making corrections too quickly. You feel yourself sinking, so you add air. Nothing happens immediately. You add a little more. Then suddenly you start rising. Now you dump air. A few seconds later, you're sinking again. This can turn into an underwater version of riding an elevator. Remember that buoyancy adjustments take a moment to affect your position. Make a small adjustment. Wait. See what happens.

Then decide whether you actually need another correction. The smaller and more deliberate your adjustments become, the easier hovering gets.

Your Trim May Be the Real Problem

Sometimes a diver thinks they're struggling with buoyancy when they're actually struggling with balance. If your legs consistently drop every time you stop kicking, adding air to your BCD probably isn't going to solve the problem. Your overall buoyancy may already be fine.

Your trim needs attention. Weight placement, tank position, body position, equipment configuration, and even where you're looking can affect how your body sits in the water.

We've covered this in more detail in Why Do My Legs Keep Sinking While Scuba Diving?, but it's an important part of hovering because good trim allows your body to remain balanced without constant movement.

What Are Your Hands Doing?

This is always an interesting one. Many divers don't realize they're using their hands until someone points it out—or they see themselves on video. A little movement here.

A small sculling motion there. A hand reaching out whenever they begin to rotate.

There's nothing inherently wrong with using your hands underwater when you need them. The question is why you're using them. If your hands are constantly moving to maintain your position, they may be compensating for another issue. Instead of simply telling yourself, "Don't use my hands," figure out what happens when you stop. If you begin sinking, look at buoyancy. If your legs drop, look at trim. If you rotate, look at balance and weight distribution. Your hand movement may be the symptom rather than the actual problem.

The Same Goes for Your Fins

Finning can hide buoyancy problems just as easily. Some divers develop a subtle sculling motion with their fins that keeps them in place without them even realizing they're doing it.

As soon as the fins stop moving, they begin sinking. Again, the goal isn't to criticize the movement. It's to understand what it's compensating for. If you can stop your fins completely and maintain your position, you know your buoyancy is doing the work instead of your propulsion. That's an important distinction.

Don't Try to Become a Statue

There's also a danger of taking hovering too seriously. The ocean moves.

You move. Your lungs fill and empty. Perfectly freezing yourself in one exact spot isn't the goal. Control is. A good hover means you can maintain your general position without constantly kicking, sculling, or making large BCD corrections. Small movements are normal.

What we're trying to eliminate is unnecessary work.

Try This on Your Next Dive

Find a safe place where you have plenty of room around you and aren't close to coral or other sensitive marine life. Establish neutral buoyancy. Get into a comfortable horizontal position. Then stop moving. Give yourself ten seconds. Don't immediately correct whatever happens. Observe it first. Did you sink? Rise? Rotate? Did your feet drop? Did your hands instinctively start moving? That information tells you what to work on. Then make one small adjustment and try again. Hovering becomes much easier when you treat it as a diagnostic tool instead of simply another skill you're supposed to "pass."

Control Comes From Doing Less

One of the interesting things about becoming a better diver is that improvement often looks like doing less. Less kicking. Less inflator use. Less hand movement. Less fighting against the water. Good divers aren't motionless because they're trying hard to stay still.

They're motionless because their buoyancy, trim, weighting, and breathing are working together.

At Your Dive Concierge, this is one of the reasons we place so much emphasis on fundamentals.

A good hover isn't useful only because it looks nice underwater. The same control helps when you're observing marine life, taking photographs, completing a safety stop, approaching a wreck, or simply enjoying a relaxed dive. If you can't stay still underwater yet, don't focus only on trying harder to hover. Stop moving and see what your body tells you.

Sometimes becoming a better diver starts with doing absolutely nothing.
