Basic Facts About Scuba Diving
 |
Discovering the world underneath the surface by Scuba diving has become a very popular water sport. The word Scuba is an acronym for 'self contained underwater breathing apparatus' and specialized scuba equipment allows the diver to breathe underwater for a significant amount of time. Snorkeling is very different because the swimmer breathes directly from the atmosphere through a mouth tube and is restricted to diving just below the water surface. During scuba diving, the swimmer carries a supply of air underwater, and there is no need to surface until the air tank is empty. The scuba diver does exhale the breathed air through a snorkel like tube into the water. Both activities require the diver to wear special eye masks to enhance and protect your underwater eyesight.
Most scuba diving is usually carried out in the seas around the world but this does not always have to be the case scuba divers can use their scuba equipment in lakes and rivers, even in swimming pools for beginners. Scuba diving equipment enables a diver to spend quite a long time underwater. Law enforcement officers frequently utilize scuba diving gear to search ponds and lakes for evidence. Military divers wear scuba diving equipment to examine ship bottoms, remove mines, or sneak ashore from ships at sea. Large industrial tanks, pools, or ponds that cannot be drained are often inspected by scuba diving experts.
The secret to scuba diving is the air supply of Compressed air which is carried in a small metal tank on the diver's back. The air in this tank is compressed to 3000 psi, allowing a great deal of air to be stored in the scuba diving tank. However, humans can only breathe air at 14.7 psi, so the tank pressure must be reduced to avoid harming the lungs. The scuba diving regulator decreases the tank pressure to breathable levels. High pressure tanks can be considered dangerous, but if properly maintained and treated well, the hazard is very small ao there is no real need to be too concerned.
Wearing scuba diving flippers, which are like the fins of fish or dolphins, on your feet improves the underwater speed and agility allowing divers to move much faster and easier. The scuba diving air tank only holds a limited amount of air, so flippers allow the divers to cover more distance while underwater. Besides the masks already mentioned, scuba divers may also wear weight belts to provide the proper buoyancy. Pressure gauges and depth gauges may also be worn to make the dive safer.
For most divers scuba diving is a purely recreational sport and they treat it as a hobby rather than a business. People have an intense desire to view the great, beautiful coral reefs of the world up close. They can view sea life from a distance of feet or even inches. Scuba diving allows an educational experience not available from a nature show on television. There is training involved in learning to use the equipment, but a novice can learn the basics of scuba diving in only a few hours. Some scuba diving professionals endure extensive training to obtain advanced scuba diving certifications.
If you like the idea of taking a scuba diving vacation, you might like to consider taking your diving lessons before you travel. That way you can spend much more time scuba diving underwater, instead of practicing in the hotel swimming pool.
