What is the main purpose of "Equalization" in diving?

The main purpose of "Equalization" in diving is to balance pressure in the middle ear. When divers descend underwater, the pressure surrounding them increases. This pressure difference can create discomfort or potential injury to the ears if not properly managed. Equalization techniques, such as the Valsalva maneuver or the Frenzel maneuver, help to equalize the pressure in the middle ear with the pressure outside the body.

By equalizing, divers can prevent barotrauma, which is damage to the ear structures caused by rapid pressure changes. It's an essential practice that divers must perform regularly during descent to enjoy a safe and comfortable dive experience. This skill is fundamental to maintaining ear health and ensuring the diver's overall well-being underwater.
