Scuba Diving – Training in Different Fields

0

A sport that has grown immensely in popularity over the past decade is that of scuba diving. Its evolution has been one from where only scientists and naturalists would use in their respective fields for further research, to being a popular pastime for many. Its growth has been so widespread that even beach resorts have offered scuba diving lessons, equipment rentals and certified trainers to accompany untrained divers who just want to try the sport out.

SCUBA stands for Self-Contained Underwater Breathing Apparatus It operates underwater with a tank or a re-breather which supplies oxygen to the diver. There are different types of scuba systems based on the breathing apparatus employed in the dive. For an open circuit scuba, the air is supplied by the tank or from another source for it to be inhaled by the diver. The air is exhaled into the surrounding water. The open circuit scuba is the most common type of equipment used for recreational purposes.

In the case of closed circuit scuba, a re-breather is used to recycle air and in the process re-introduce oxygen into the air supply of the diver by another apparatus. For a semi-closed circuit scuba, the air supply has in it a mixture of gases. These gases retain some of the air exhaled by the diver and is added to an air supply similar to that which is used in an open scuba system. Semi-closed circuit scubas are more difficult to learn than open or closed circuit scuba diving alone. There is a fusion between the two therefore knowledge of both types of diving is a must.


To expand the growing popularity of scuba diving, lessons in diving are offered by scuba diving clubs and other organizations. Scuba diving lessons are not just limited to beginners, but also available on a more professional level to trained divers to help expand their repertoire. They are able to go diving in conditions and environments that are practically out of the depth of other divers who do not possess the training to handle them.

Regular Scuba Certification

This is the training of a person in scuba diving beginning with the basics. A majority of people who take up scuba diving as a hobby usually have a regular scuba certification. The basics include allowing the operation to take place in shallow water and near the shoreline.

Open Water Scuba

Open water scuba is for scuba divers who operate out of the sight of the shoreline. A boat is usually used for this operation and a pre-requisite would be the skills of operating a boat. This involves diving to greater depths than a regular diver and more specialized equipment such as floater buoys to show the spot of divers on the surface to other boats. Also included are underwater line markers, reels and underwater floaters essential for underwater navigation.

Rescue Scuba

This is a special training course with an emphasis of rescue operations for other divers. Rescue scuba is a must for those who are employed in the search-and-rescue business. First aid is just the beginning of the training which includes underwater techniques for getting people out of hazardous and potentially life threatening situations like underwater caves. Training in the usage of specialized equipment is also carried out.

Deep Dive Scuba

Deep dive scuba is diving in extreme deep water conditions and encompasses training in the use of equipment for operating in high pressure depths. It is really dangerous and is not recommended for casual divers who take it as a hobby since it involves descending to depths that feature water pressures that would physically crush a person wearing regular scuba gear. Naturalists usually take up this training as a way to study life forms that can only be found at the bottom of the sea. On the same note, geologists and oceanologists likewise take it up to study underwater formations such as volcanoes and rock fissures.

Hazardous Area Scuba

Hazardous area scuba training specializes in teaching scuba divers advanced forms of safety in scuba diving. Diving skills required here are not that much different to regular scuba however additional training is given to allow a diver to explore hazardous areas like ship wrecks, coral reefs infested with toxic life forms, shark infested waters and underwater caves. Serious scuba divers take this up mainly for the thrills that the exploration provides.

Instructional Courses

This scuba course gives a scuba diver the ability to teach other people to scuba dive. It encompasses training in basic first aid as well as tutorials in buddy systems that are required for helping new divers along underwater. Certificate in a basic entry level scuba diving is a must for taking this course. However no proficiency in the more advanced courses is necessary to focus on teaching others the methods of recreational scuba.
