Face
mask
A diver's face mask acts as a window into the underwater world. As the human eye is unable to focus under water due to its optical density, the mask compensates by providing an air gap between the eye and the water. Modern masks are usually made from several pieces; a rigid plastic frame that holds the lens or lenses, a silicon rubber skirt to provide a comfortable and watertight seal against the face and a silicon rubber strap and many masks feature a two lens design that can be fitted with prescription lenses if desired.
A mask should be chosen for fit and comfort and the user will benefit
from a large lens area and small volume, which reduces mask squeeze. To
check whether a mask fits correctly or not, the wearer should put the
mask to their face without using the strap and breathe in slightly. If
the mask is comfortable and does not fall away from the face it is a good
fit.

Fins
Fins simply allow the diver to more more easily in the water by providing
a large surface area to provide propulsion. Fin technology has moved on
in the last few years, and there are various designs available designed
to help give extra thrust. However, there are two basic styles available.
The first style which is more usual for scuba diving has an adjustable
strap to fit over wetsuit boots. The second style is full foot and worn
directly on the feet. The latter are usually worn by snorkellers and divers
in warmer waters.

Snorkel
You may wonder why a scuba diver with a cylinder full of air would require a snorkel. The answer is simple; to preserve air while on the surface. If a dive requires a diver to make a surface swim before descending then it makes sense to save the air for the dive, but allow the diver to swim comfortable face down. This is even more important if there are waves, which can make breathing at the surface difficult.
A basic snorkel has a mouthpiece and a length of tubing that remains above the surface. Snorkels can vary in their design, some featuring splashguards to avoid allowing water into the snorkel through the top, but a feature of many is a purge valve next to the mouthpiece. This allows water to be expelled more easily, as it does not have to travel up the length of tube.
Snorkels are usually fixed on the left side of the mask strap to ensure
it does not interfere with the second stage regulator,
usually worn on the right. One thing to watch for is how the snorkel fixes
to the mask. Many are not as secure as they should be, which can result
in the loss of the snorkel.
