What is the recommended practice for equalizing during deep dives?

The recommended practice for equalizing during deep dives is to equalize frequently and early to avoid ear injury. This approach is critical because the pressure increases with depth, which can lead to discomfort and potential barotrauma if the pressure in the middle ear isn't equalized quickly enough. Frequent equalization helps keep the pressure balance in the ears aligned with the surrounding water pressure, reducing the risk of pain and injury associated with pressure changes.

Equalizing early and often also allows divers to be proactive about their comfort and safety, ensuring that they do not wait until they feel discomfort. Waiting for discomfort can lead to a more challenging equalization process and increases the likelihood of injury, making this proactive approach essential for safe deep diving.
