My perception of a pristine and peaceful scuba dive changed when I went for my first dive off the Great Barrier Reef. It looks so easy in the movies, but the breathing underwater with an oxygen mask is difficult. Don’t let those practice lessons in the swimming pool fool you! To make it easier for us, here is the Triton Oxygen Mask For Diving. It is a very convenient oxygen respirator concept that allows us to breathe under water for a long time by simply biting it.
