Good job! Now you know how to clear your mask of water. Practice this skill until it becomes automatic and comfortable. Once you are an expert at mask clearing, try the exercise in a variety of positions. You can even clear your mask while maintaining a proper, horizontal swimming position.
This skill has another application. If a mask fogs up during a dive (click here to learn more about foggy masks), you can clear the fog from the mask lens using the mask clearing skill. Simply allow a small amount of water to drip into the mask, then tilt your head down so that the water flows down into the mask lens. Shake you head gently side to side so that the water contacts all parts of the mask lens, then clear the mask normally. Presto! Now you can enjoy a clear view of the underwater world during every part of the dive.
