Freediving Equalisation Drills That Work

The first few metres can decide an entire freedive. If pressure starts building in your ears before you have even settled into the descent, it is easy to tense up, kick harder and turn a calm session into a frustrating one. The right freediving equalisation drills help you build control before depth asks too much of you.

Equalising is not about forcing air into your ears. It is a gentle, repeatable skill that depends on timing, relaxation and understanding what your body is doing. Whether you are preparing for your first freediving course or working towards cleaner, more confident descents, practise on dry land first and take that calm control into the water.

Why equalisation becomes difficult

As you descend, water pressure increases and the air spaces in your ears and sinuses compress. To stay comfortable, you need to add air through the Eustachian tubes before the pressure difference becomes noticeable. The crucial word is before.

Many new divers wait until they feel pain or strong pressure, then try to equalise hard. That is usually where the problem starts. A late equalisation can be difficult to clear, and pushing harder may irritate the ears or sinuses. Good freedivers equalise early, gently and often, rather than waiting for a warning signal.

Technique matters, but so does your state of mind. A lifted chin, tight jaw, rushed breathing, cold water or the feeling that you must reach a certain depth can all make equalisation harder. This is why the best practice is not just mechanical. It teaches your body to stay loose when there is something new to do.

Safety first: discomfort is feedback

Equalisation should never hurt. A light pop, click or feeling of release can be normal. Sharp pain, dizziness, persistent blockage, blood from the nose, ringing, or reduced hearing are clear reasons to stop and seek medical advice if symptoms continue.

Do not freedive with congestion, a cold, inflamed sinuses or an ear infection. Decongestants are not a reliable shortcut either. They can wear off during a session and leave you unable to equalise on the way back up, which is a risk no enjoyable water day is worth taking.

Never force an equalisation attempt. Avoid aggressive blowing and do not continue descending while one ear has not cleared. In open water, practise with a trained buddy and within the limits of your training. A qualified instructor can spot a small issue in head position or technique that is almost impossible to diagnose alone.

Freediving equalisation drills to practise on land

Dry practice gives you time to learn the movement without waves, depth or a mask distracting you. Keep sessions short - five to ten minutes is plenty - and stop if you feel discomfort. You are training coordination, not trying to overpower your ears.

Start with jaw, face and neck relaxation

Sit upright with your shoulders down. Let your jaw hang loose, then slowly move it side to side as if you are chewing. Yawn gently, relax your tongue and take a few easy breaths. Notice whether you tend to clench your teeth or press your tongue hard against the roof of your mouth.

Now pinch your nostrils and try a gentle swallow. Some people feel a small release in both ears. Others may notice only one side at first. That is useful information, not a failure. Repeat several times without straining, keeping your face and neck relaxed.

This simple drill is especially valuable for people who find that one ear regularly lags behind the other. It will not solve every anatomical issue, but it can reveal how much tension is getting in the way.

Learn the Frenzel movement slowly

For freediving, the Frenzel technique is generally more useful than blowing from the chest. Rather than using lung pressure, you close the airway and use your tongue like a small piston to compress air in the mouth and send it towards the ears.

Begin by pinching your nose and making a gentle sound like the letter K or G, without letting air escape from your nose. You may feel your ears click. The aim is a small, precise movement, not a dramatic one. Keep your throat relaxed and avoid puffing out your cheeks.

A helpful checkpoint is your abdomen and chest. If they are moving strongly as you equalise, you may be relying on a Valsalva-style blow rather than Frenzel. There is nothing wrong with using a gentle Valsalva on the surface if it works for you, but it becomes less effective as you go deeper because the air in your lungs is under increasing compression. Building Frenzel early gives you more options as your freediving develops.

Practise with a full mouth of air

Take a normal breath, then collect a small amount of air in your mouth with your tongue. Pinch your nose, close your throat and make the K or G movement. Try to keep the air in your mouth rather than allowing your cheeks to inflate and deflate.

This drill helps you feel the difference between using the tongue and pushing from the lungs. It can take time, particularly if you have equalised by blowing your nose for years. Small, frequent practice sessions are more effective than one long session of forcing it.

Add your head position

Freedivers often equalise easily upright, then struggle once they tip head-down. Rehearse the same gentle movement while bending forward at the hips, first with your head neutral and then slightly tucked. Do not crank your chin towards your chest. Think long neck, soft jaw and eyes looking naturally towards where you are going.

If the technique disappears as soon as you lean forward, slow down. Return to an easier position, find the movement again, then gradually increase the angle. This is the bridge between a dry drill and a real descent.

Take the skill into the water gradually

Your first water sessions should be about technique, not depth. At the surface, take time to settle your breathing and check that you can equalise gently before duck-diving. Once you descend, equalise immediately, then continue to do so every half-metre to metre in the early part of the descent. The exact rhythm varies from person to person, but frequent is better than late.

Use a line and move slowly enough to notice what is happening. If an ear feels delayed, pause your descent. Rise a little if needed, relax, equalise and only continue when both sides feel clear. Turning a dive early is a smart decision, not lost progress.

For beginners, a shallow session with excellent equalisation is far more valuable than chasing a number. In the clear coastal water around the Causeway Coast, it can be tempting to focus on the scenery below. Enjoy it, but keep your attention on your body first. Comfortable ears create the freedom to enjoy everything else.

A simple practice routine before a session

Before getting in the water, give yourself a minute to check in. A useful routine has four parts:

• Check that your ears and sinuses feel clear, with no cold or lingering irritation.

• Relax your jaw, neck and shoulders with a few gentle yawns or chewing movements.

• Perform several easy Frenzel attempts at the surface, never forcing a pop.

• Set a conservative plan: slow descent, early equalisation and permission to turn around.

This routine is not glamorous, but it changes the tone of a session. You arrive at the line prepared rather than hoping your ears will cooperate.

When drills are not enough

If you repeatedly cannot equalise one side, feel blocked for hours after diving, or only manage to clear by forcing hard, pause your depth training. Ear and sinus structure varies, and a persistent issue deserves individual support from a suitably qualified medical professional and a freediving instructor.

It also depends on your goal. Someone enjoying shallow snorkelling may do well with gentle swallowing and regular surface checks. A diver progressing towards greater depth needs a dependable Frenzel technique, head-down control and a more structured approach to mouthfill later in their training. There is no prize for rushing through the stages.

At Freedive NI, instruction begins with the basics because confident depth starts with calm, comfortable ears. Give these drills patient attention, keep every attempt gentle, and let clean equalisation become the quiet skill that carries you towards more amazing water-based experiences.
