A dive center is basically the first base point where most recreational divers learn or make supervised dive tours at new underwater locations. Most dive centers are operated under the guidelines of ISO 24803, in which case all the facilities should conform to the minimum standard of a qualified service provider for scuba diving. This means that you will need a dive center that meets all the necessary safety and environmental requirements and can also provide scuba certification and instruction. check this out for more info.
Scuba certification is not mandatory for anyone who wishes to learn to dive, but it does give the person an edge over potential competitors. Scuba certification is usually obtained by taking either a general or advanced scuba certification course, and sometimes both. The courses usually last from two to four days and involve classroom training, although some centers offer a short vacation package for those who are keen on getting a head start. The final exam, often given after the training is completed, covers practical applications and written exams. Getting certified takes about 200 hours of classroom instruction plus the study time needed to pass the final certification exam.
In addition to being able to dive safely, you will also be exposed to some extreme conditions that might otherwise be beyond your skill level. Since scuba diving is an expensive hobby, most diving centers will only hire very experienced divers or those with extensive experience under their belt. If you would like to learn to dive but don’t have much experience, you could try a basic course at a local diving center or university before going solo. This would allow you to get some real experience before spending big money on your first open water scuba certification class. You can then take your certification test at your local pool and work your way up from there.
