• Snorkeling

  offers a straightforward way to discover the underwater realm, providing a glimpse into marine life without frequent resurfacing for air.
• With a snorkel and mask, individuals can leisurely observe underwater wonders.
• Beyond leisure, snorkeling aids in water-based search and sports like underwater hockey, rugby, and spearfishing.
• Snorkeling began a long time ago when people used simple tools to breathe underwater. They made tubes out of things like reeds to help them stay submerged and explore underwater places.
• As time went on, people improved these tools, and in the 20th century, they created the snorkel we use today with the help of scuba diving technology. (Bellis, 2020)
• Snorkeling in German is called Schnorchel means to breathe through a tube.
• Hollow Reed (3000 BCE)

  In 3000 BCE, early divers used hollow reeds as a breathing mechanism to explore underwater for longer periods of time.
• The first goggles from tortoise shells (1300s)

  During the 1300s, Persians introduced goggles made from thinly sliced and polished tortoise shells, improving underwater vision for divers.
• Hollowed tube and a sketch of webbed swimming gloves (1400s)

  In the 1400s, Leonardo da Vinci designed a snorkel-like device with a hollowed tube attached to a diver's helmet.
• Wooden Paddles (1717)

  In 1717, Benjamin Franklin proposed wooden paddles attached to swimmers' hands and feet to enhance swimming speed, providing better maneuverability in the water.
• Modern Fins (1912)

  In 1912, Frenchman Louis de Corlieu invented modern fins with rubber foot pockets and blade-like extensions, enabling swimmers to propel themselves more effectively, and he obtained a patent in 1933, leading to widespread use of fins in water sports.
• Snorkeling equipment has evolved with time, gaining sophistication and diverse designs. The essential gear includes fins, a snorkel, and a mask. Additionally, some opt for a rash guard and floating vest, although usage varies.
• BASIC SNORKELING EQUIPMENT

  Mask

  Snorkel

  Fins

  Rash Guard

  Floating Vest
• MASK

  provides clear underwater vision by creating airspace, preventing distortion or blurriness underwater.
• STRAP

  Holds the mask to the face under water.
• PARTS OF THE MASK

  STRAP

  MASK SKIRT

  NOSE POCKET
• MASK SKIRT

  The soft flexible material that seals the mask around the face.
• The nose pocket in masks shields and cushions the nose. Some masks include a purge valve at the bottom to help drain water.
• HOW ARE THE GEARS SET UP?

  Step 1: Clean and defog the mask.

  Step 2: Attach the snorkel to the mask.

  Step 3: Put on the mask.

  Step 4: Wear the snorkel.

  Step 5: Put on the fins.
• FOGGING

  OCCURS WHEN WARM, HUMID AIR INSIDE THE MASK MEETS THE COLD LENS, CAUSING CONDENSATION AND OBSCURING VISION. KEEP IN MIND, UNDERWATER, THE DIVE MASK LENS GETS COLD.
• Defogging

  is a method used to prevent the mask's lens from getting hazy underwater. It helps to avoid the formation of tiny droplets or moisture on the inside of the mask's lens.
• SNORKEL

  enables breathing while submerged by featuring a tube, or barrel, with a mouthpiece. The tube end stays above water, while the mouthpiece fits into the mouth. A clip attaches the snorkel to the mask for convenience.
• TYPES OF SNORKEL

  classic snorkel (open top)

  semi-dry snorkel (splash guard)

  dry snorkel (dry valve & splash guard)
• CLASSIC SNORKEL

  has the most basic parts, the solid tube and the mouthpiece. Sometimes this can be bent to a specific shape.
• The snorkel with a flexible tube below the strap attachment point is more comfortable than the classic snorkel.
• Flexible tube

  allows the top and mouthpiece to rotate to different angles to better fit the face. It can also drop away from the face when not in use.
• Purge Valve

  a common feature of many snorkels. This is a small valve just lower than the mouth that empties the collected water that comes down the tube when one blows it out.
• Splash Guard

  prevents splashed water and spray from easily entering the tube.
• SNORKELING FINS

  They extend snorkelers' range and shield feet from rocks and corals..
• Water resistance propels objects, aiding fins in swimming.
• Two types of snorkeling fins exist: full-foot and adjustable.
• The full-foot fins cover the heel and are put on like slip-on shoes.
• Adjustable fins, with adjustable straps, are commonly used with dive boots for cold water diving.
• In recent years, a new subclassification emerged in both full-foot and open-heel fins: conventional paddle-bladed fins and split fins.
• Paddle-bladed fins have a single full blade, while split fins feature two long, stiff blades separated in the web.
• Paddle-bladed fins provide fast-accelerating speed through long, slow strokes, enhancing control and maneuverability, particularly when moving around corals, and can be used with various kicking strokes.
• Split fins make kicks easier and leg strokes more rapid, directing water force more directly behind the fin than paddle-bladed fins.
• TYPES OF FINS

  full-foot fin

  adjustable fin

  paddle-bladed fin

  split fin
• SNORKEL VEST

  are small and inflatable, which provide more buoyancy while floating on water.
• SWIMMING CAP

  is a big help in keeping hair out of the snorkel and the face as well.
