Snorkelling

The Details And Basics

What is Snorkelling?

Snorkelling is the practice of swimming through a body of water while equipped with snorkelling gear (diving mask, a snorkel, wetsuit and fins). It is a popular recreational activity and it is performed to quietly observe marine life in its natural habitat. Snorkelling is suitable for all ages because of the litle effort it involves.


Caring For Your Snorkelling Gear

Mask- you should apply a small abrasiveto the lens surface. Once the mask is clean, apply an anti-fog soloution around the mask lenses. Give the mask a quick rinse in salt water before you dive.


Snorkal- Rinse your snorkal in water after every use and check your mouthpiece, snorkal keeper and the purge valve for wear and tear.


Mouthpiece- Check your mouthpiece for bitemarks and tears.


Fins- Rinse after each dive and store in a dark place away from direct sunlight.


Underwater Science

Ears- If you descend more than a few feet from the surface you may begin to feel some pressure on your ears. If so, you will need to equalize the pressure before proceeding further. For some, this may happen naturally; others may need to make a conscientious effort; and for some it may be impossible to clear the ears due to a cold or other sinus problems. Pressure on the ears is equalized by holding one's nose and blowing gently.

Skills

Finning- Flutter Kick- This is most likely the first style of finning you are taught when you’re learning to scuba dive. In this standard kick, the legs move up and down in opposing directions with a fairly straight leg. The Modified Flutter Kick-This is the most common and practiced by many. It involves a flutter kick with the knees bend. It still propels the diver but at reduced efficiency and less effort. Scissor Kick- The body position in this technique looks like the flutter kick i.e legs straight,knees slightly bent. But, the leg motion is quite different. Instead of the legs crossing each other in an up and down movement, the legs are widened and then brought together sharply (like a pair of scissors closing) and held in that position for a glide count. The Frog Kick- This style of kicking is one of the most popular among cave divers to avoid kicking up silt or sand in confined spaces. In the frog kick the body and upper legs maintain a straight, horizontal trim but the knees are bent so the fin blades point upward on a steep diagonal. The Backwards Kick-As the name suggest this is for moving away from objects or moving backwards. It’s not an easy or elegant kick, but is useful in many situations. This technique is almost a complete reverse of the frog kick, the fins work through the first half when your legs move out and way from you then pulling them close to your body, scoop the fins forwards and stopped halfway to prevent you from moving forward.

First Aid

The most urgent emergencies specific to scuba diving generally involve loss of breathing gas: Gas supply failures, situations where breathing air is likely to run out before the diver can surface, or inability to ascend, and uncontrolled ascents. First Aid application invloves gas exchange and emergency asencions to apply CPR.
