Scuba Diving Adventures
Scuba Diving Introduction
Scuba diving is a form of underwater diving in which a diver uses a scuba set to breathe underwater for recreation, commercial or industrial reasons. “SCUBA” is an acronym for self contained underwater breathing apparatus and is now widely considered a word in its own right. Unlike early diving, which relied solely on air pumped from the surface, scuba divers carry their own source of breathing gas, usually compressed air. Not being attached to an air line allows scuba divers more freedom than people who snorkel or free dive. Depending on the purpose of the dive, a scuba diver usually moves underwater by swimfins attached to the feet, but external propulsion can come from an underwater vehicle or a sled pulled from the surface. Scuba diving may be performed for a number of reasons, both personal and professional.
Most people begin with recreational diving, which is performed solely for enjoyment and has a number of distinct technical disciplines to increase interest underwater, such as cave diving, wreck diving, ice diving and deep diving. Many people will seek scuba diving lessons in order to obtain a scuba diving certification and move on to more professional interests.
Scuba Diving Lessons
Scuba diving lessons are a great way to learn about some of the finer points of scuba diving equipment and the hazards that exist while scuba diving. The most commonly used scuba set today is the “single-hose” open circuit 2-stage diving regulator, coupled to a single pressurized gas cylinder, with the first stage on the cylinder and the second stage at the mouthpiece. In the “single-hose” two-stage design, the first stage regulator reduces the cylinder pressure to an intermediate level. The second stage demand valve regulator, connected via a low pressure hose to the first stage, delivers the breathing gas at the correct ambient pressure to the diver’s mouth and lungs.
Due to the complexity of scuba diving equipment, many dangers exist. Pressure injuries, called barotrauma, can be quite painful, in severe cases causing a ruptured eardrum or damage to the sinuses. To avoid them, the diver equalizes the pressure in all air spaces with the surrounding water pressure when changing depth. If properly equalized, the sinus passages can stand the increased pressure of the water with no problems. However, congestion due to cold, flu or allergies may impair the ability to equalize the pressure. This may result in permanent damage to the eardrum.
Although there are many dangers involved in scuba diving, divers can decrease the dangers through proper training and education. Therefor scuba diving lessons are imperative and you should always consider open-water certification programs that highlight diving physiology, safe diving practices, and diving hazards.
Scuba Diving Certifications
The kind of Scuba diving certification you will need depends on the kind of scuba diving you will being doing. Recreational scuba diving does not have a centralized certifying or regulatory agency, and is mostly self regulated. There are, however, several large diving organizations that train and certify divers and dive instructors, and many diving related sales and rental outlets require proof of scuba diver certification from one of these organizations prior to selling or renting certain diving products or services. Some of the agencies that can help with your scuba diving certification needs are: British Sub Aqua Club, National Association of Underwater Instructors and the Professional Association of Diving Instructors. Make sure you are prepared with the right scuba diving certification for your next scuba diving adventure.
Scuba diving can be a complex adventure. Make sure you have the proper scuba diving lessons, scuba diving equipment and scuba diving certification for your next scuba diving adventure. Next time your already out to sea enjoying your next scuba diving adventure remember that a guided fishing charter is also a great addition to any scuba diving adventure.
