How to Equalize While Freediving

Equalization is the process of balancing pressure in the middle ear and other air spaces as you descend underwater.

As depth increases, pressure changes quickly. Equalizing early and frequently helps prevent discomfort and injury.

Equalize before you feel pain

A common beginner mistake is waiting until the ears feel uncomfortable. By that point, the pressure difference may make equalization more difficult.

A better approach is to:

• Begin equalizing at or just before the descent.
• Equalize gently and frequently.
• Stop descending if an equalization does not work.
• Ascend slightly and try again without force.
• End the dive if pressure or pain continues.

Never continue descending through ear or sinus pain.

Frenzel equalization

Many freedivers use the Frenzel technique. It uses the tongue and throat to create pressure rather than relying heavily on the chest and abdominal muscles.

Frenzel is generally more efficient for freediving than forceful equalization methods, but it can take time to learn. Dry practice with an instructor can help you understand the movement before applying it underwater.

Why equalization sometimes fails

Equalization can be affected by:

• Starting too late.
• Descending too quickly.
• Tension in the face, jaw or throat.
• Poor head position.
• Congestion, allergies or a recent illness.
• An inefficient equalization technique.

Do not dive when congestion prevents comfortable equalization. Never use medication simply to hide symptoms so you can dive without appropriate medical advice.

Equalization is a skill

Difficulty equalizing does not mean you are bad at freediving. It is one of the most common obstacles for beginners.

During a course, we can slow the descent, remain shallower and work on technique before adding depth. Progress comes from comfortable repetition, not force.

Equalization is taught during the AIDA 1+2 beginner course and can also be addressed during a private training session.
