Equalization Techniques: A Complete Guide

Why Equalization is Critical

Equalization is the process of balancing the pressure in your ears and sinuses as you descend. Failure to equalize properly can lead to discomfort, injury, and in severe cases, permanent damage.

The Valsalva Maneuver

The Valsalva is the most common equalization technique. Pinch your nose and gently blow to force air into the Eustachian tubes. While effective, it becomes difficult at depth and can lead to over-pressurization.

The Frenzel Technique

Frenzel is considered the gold standard for freediving. It uses the tongue and soft palate to compress air, allowing equalization at greater depths with less effort. Mastering Frenzel takes practice but dramatically improves your diving comfort.

Tips for Successful Equalization

• Start equalizing at the surface before descending

• Equalize early and often—every meter or two

• Never force it—if you can't equalize, ascend slightly and try again

• Stay well hydrated to keep mucous membranes functioning
