■Snorkel Clear

To clear your snorkel, inhale a large breath at the surface and blow strongly into the snorkel.

■Fin Work

While slightly bending the legs, we slowly and in a large cycle kick with our whole legs. With this method we can gain suitable propulsive power. As well, swimming while looking forward works well.

■Communication

Since we can’t speak underwater, there is a tradition of using simple hand signals.
