Freediving Equalization: 6 Tips to Reach 20 Meters

Equalization

Freediving is a thrilling journey into the depths of the underwater world, but to do it effectively and safely, mastering equalization is essential. Equalization balances the pressure in your ears and sinuses with the increasing pressure of the water around you, allowing you to dive deeper comfortably. For beginner and intermediate freedivers aiming to reach 20 meters, following these five key equalization tips will make a world of difference.

1. Start with a Head-Up Descent to Accommodate Your Ears

When you’re new to freediving or still building confidence with equalization, starting your descent with your head up can help ease the pressure changes in your ears. A head-up descent creates a gentler angle for your Eustachian tubes, making it easier for air to flow through and equalize your middle ear.

2. Equalize Once on the Surface Before Descending

Pre-equalizing at the surface sets you up for success during your descent. By gently equalizing before you even start diving, you’re preparing your ears for the pressure changes that will occur almost immediately. This small habit helps reduce the initial pressure and makes it easier to continue equalizing smoothly as you descend.

3. Focus on the Rope in Front of You, Don’t look down

Maintaining proper posture during your descent is crucial for effective equalization. Looking straight at the descent line (or the rope, if you’re diving along one) helps keep your neck and head aligned. Avoid the common mistake of looking down, which can strain your Eustachian tubes and make equalization harder.

4. Master the Frenzel Equalization Technique

The Frenzel maneuver is the gold standard for freediving equalization. Unlike the Valsalva method, which involves using your stomach muscles to push air into your Eustachian tubes, Frenzel relies on your tongue and throat muscles to create pressure in your middle ear. This method is more precise, efficient, and suitable for the increasing pressures of deeper dives.

To perform the Frenzel technique:

  • Pinch your nose
  • Seal off your glottis (the opening at the back of your throat)
  • Use your tongue to push air towards your Eustachian tubes

Frenzel equalization takes time to mastered, you can practice on land using a dry equalization tools like an otovent. You can find plenty of tutorials online to help you get started like this one.

5. Equalize Often, Hold at bit for Progressive Eustachian Tube Opening

Consistency is key when it comes to equalization. Instead of waiting until you feel discomfort or pressure in your ears, make it a habit to equalize often during your descent. When equalizing, keep the pressure for 2 or 3 seconds allows your Eustachian tubes to open progressively, ensuring a more comfortable dive.

If you feel resistance or discomfort, stop your descent immediately and try equalizing again before continuing. Never force it—your ears need time to adapt.

Conclusion

Equalization is one of the most critical skills for safe and enjoyable freediving. By following these five tips, you’ll be well-equipped to handle the pressure changes of deeper dives while keeping your ears and sinuses comfortable. Stay patient, keep practicing, and soon, that 20-meter depth will feel like a natural extension of your freediving journey. Dive safe, and enjoy the wonders of the underwater world!
