Snorkeling - is a swimming discipline on or through the bodies of water while equipped with diving goggles, a typical U-shaped tube used for breathing which is called as “snorkel,” and swim fins.
Mask - serves as the viewing device in appreciating the world beneath the water. Without the mask, everything viewed underwater will be blurred or distorted.
Mask squeeze - a condition where the soft tissues beneath the mask, especially around the eyes, swell and discolor.
Snorkel is a piece of equipment that makes it possible to breathe at the surface while the face is submerged in water.
splash guard - prevents splashed water and spray from easily entering the tube.
Dry valve - is a special valve on top of the tube that completely stops water (and air) from entering the tube when a wave comes or when diving underwater.
There are two basic kinds of snorkeling fins
a. Full-foot fins cover the heel and are put on like slip-on shoes.
b. Adjustable fins, on one hand, are open at the heel and have adjustable straps to secure the feet.
Snorkel vests - are small and inflatable, which provide more buoyancy while floating on water. This will help in consuming less energy in moving around.
Swimming cap - is a big help in keeping hair out of the snorkel and the face as well. It will also help in preventing the scalp from burning on a sunny day
Mask defogger - helps prevent the mask from fogging up.
