Question

Which of the following is not true? Divers should equalize:

1) Preemptively before descent.
2) Well before feeling any pain or discomfort.
3) As soon as they feel any pain or discomfort.
4) Early and often during descent.

Answer 1

Divers should equalize preemptively before descent, well before feeling any pain or discomfort, and early and often during descent.

Step-by-step explanation:

Divers should equalize preemptively before descent to prevent a buildup of pressure in the ears and sinuses. They should also equalize well before feeling any pain or discomfort as a precautionary measure. Divers should not wait until they feel pain or discomfort to equalize, as this can lead to injury. Finally, divers should equalize early and often during descent to continually equalize the pressure in their airspaces.
