Equalize every metre/few feet while descending, before you feel discomfort. If you wait until you feel discomfort, you may not be able to equalize because water pressure may be great enough to hold the air passages shut. Instead, if you feel discomfort in an air space, ascend until the discomfort eases, equalize and continue a slow descent equalizing more frequently. You'll find it easier to equalize with experience.

If you can't equalize, discontinue the Bali scuba dive. Continuing to descend with an unequalized air space may result in a ruptured ear drum or similar injuries. Never attempt a forceful or extended equalization - that can also cause serious ear injuries, including a ruptured ear drum, which can cause vertigo. Should this occur, abort the Bali scuba dive. If ascending a metre/few feet and trying again doesn't permit you to equalize, don't force it. Be patient and gentle, or end the Bali scuba dive and try another day.

You can also create an unequalizable space in your ear canal, either by wearing a too-tight wet suit hood that inadvertently seals against your ears, or by wearing ear plugs. In either case, you end up with an air space between your ear drum and the plug/hood that you can't equalize. To prevent this, pull your hood away from your ears momentarily to allow the pressure to equalize, and nez er wear ear plugs while Bali scuba diving. The only exceptions are special ear protectors made specifically for Bali scuba diving that allow for pressureequalization.

Congestion (due to colds or allergies) can plug air pas-sages, making equalization difficult or impossible. Medications, such as sprays and decongestants, may clear the openings, but you shouldn't do this and Bali scuba dive because the medication may have undesirable side effects (such as drowsiness) and may wear off while you're Bali scuba diving, creating equalization problems when you try to ascend
