Working divers, such as public safety divers, use full-face masks because they protect the eyes and nose from contaminants in the water, provide comfort in cold water, and allow for underwater audio communication. If you're interested in public safety diving, scientific diving, or venturing into extremely cold water, then learning to dive with a full face mask is definitely for you. Because full-face masks allow you to breathe through your nose, they are also beneficial for those who have difficulty using standard scuba masks. Diving with a full face mask offers a different experience and even offers some with physical disabilities an opportunity to try scuba diving. As a SSI SPI FFM you’ll be able to teach and certify other divers in the FFM diving specialty.
