Perhaps
the most important piece of gear is your mask. You will
need a high quality mask with a tight-fitting seal. Silicone
is considered preferable to rubber for the skirt. The easiest
way to test the fit of the mask is to lift the strap over
the top of the mask and press the mask to your face (being
sure not to capture any strands of hair) without breathing
in. If it creates a slight vacuum and stays tight to your
face, you've got the right fit. If not, move on until you
find one that does seal properly. A proper fit will make
a great difference in your enjoyment.
A snorkel is a snorkel. Not
true! There are varying bore sizes, different designs, alternating
internal air pockets, etc, etc. Where to start? Try to find
a snorkel that is comfortable, delivers air easily and breathes
as dry as possible.
Your
fins give you mobility and speed. Remember this, not
all fins are created equal. The variables are foot pocket
design and fin size and shape. You have a choice between
full-foot fins (ones that fit like a slipper around your
heel) or open-heel fins. The latter are worn with some type
of neoprene reef slipper with a flexible rubber sole. In
either case, your fins should fit snugly but not too tight.
