Apnea Diver - Special Collection
The blue, white and red colors spread out over a certain number of seconds replicate an internationally recognized breathing exercise in freediving: Breathing in during the five-second blue phase, holding for the 15-second white area and then exhaling over the 10-second red area. This color coding allows the freediver to concentrate fully on his or her breathing without needing to count or use a stopwatch.
