If you're wearing a
flotation vest, put it on and
inflate it about halfway.
Don your mask and adjust the strap. If you have anything
other than very short hair, it's usually easiest to put the mask on
your face first, then pull the strap over your head.
Bite down on the snorkel mouthpiece (not too hard!), so that the
bite tabs are between your teeth, and the main part of the mouthpiece
is between your lips and teeth.
Breathe in and out. You'll notice a little resistance when
you breathe heavily - that's normal, and is caused by the resistance
of air flowing through the snorkel tube. Slow and steady
breathing is best.
