The Frenzel technique in freediving: the key to the depths

The Frenzel technique is the major upgrade in equalization skills, and opening it opens the depths to you.

The difference between Valsalva and Frenzel

Valsalva relies on the lungs for pressure. Frenzel relies on the throat muscles and the tongue diaphragm. It is more efficient and suitable at depth.

Why Frenzel is better at depth

At greater depths the lungs compress and become hard to use for pressure. Frenzel works with muscles independent of the lungs and remains effective at the greatest depths.

Learning Frenzel: step by step

First: finding the muscle
Close your nose and try to say the letter K strongly. You will feel movement in the back of the throat. This is the required muscle.

Second: dry training
Practice moving this muscle out of the water in front of a mirror for weeks until you master it.

Third: application in the water
Start at a small depth and apply Frenzel. You will feel the difference immediately in the efficiency of ear equalization.

Learning Frenzel requires weeks of patience, but the fruits last for years of diving at greater depths.
