There are numerous PADI® courses you can take when it comes to diving! Of course to enjoy diving, you need not take them all. Learning these courses are not difficult. Like learning anything else, scuba diving takes time, practice and patience! The dive courses are generally 'performance-based', which literally means learning it at your own pace and time.
A place to start is the 'Open Water Dive Course'. In this course, your instructor teaches you the basics of learning how to scuba dive. On top of the classroom theory, you will proceed to the confined-water lessons, i.e. pool, where you apply the theory you learnt, and thereafter, progress to the open water training, such as the ocean or lake, at the same time getting accustomed to diving. After this introductory course, you are able to go to the open sea!! You decide how fast you want to go. If you have a busy schedule, you can opt to do it every other day or in the weekends. However, if you are the 'expeditious' type, you can complete it in 3 to 4 days! Whichever way you do it, don't forget to have fun!
When you feel more comfortable in the water, you can proceed to take the 'Advanced Open Water Dive Course'. Here, you choose 5 different dives from a large variety of dives, which include the drift dive, wreck dive, deep dive, night dive, underwater navigator dive, underwater photography dive, and much more! The skills you obtain from these dives make diving much more exciting and interesting! Additionally, the Advanced Open Water Dive course brings you closer to the Master Scuba Diver, which is the ultimate non-professional certification in recreational diving. Apart from learning new techniques underwater, this course strengthens your skills and dexterity in diving!
Another important dive worth taking is the 'Rescue Diver Course'. Although this course is often described as challenging, it adds to your confidence and understanding in diving while at the same time introduces the element of 'rescue' into dives. Rescue Divers learn to look away from themselves and consider the safety and well being of other divers. This course will enable you to look out for and avoid problem areas, and also if necessary, manage dive emergencies. This course will cover self-rescue and diver stress, emergency management and equipment, panicked diver response, in-water rescue breathing protocols, egress, and dive accident scenarios; all of which will come in handy.
If any of these dives don't sound enticing to you or if you are still undecided on venturing into scuba diving, maybe the 'Discovery Scuba' dive lesson is the one for you! This short lesson basically comprises 1 hour or so of confined underwater environment, i.e. in the pool or shallow waters, wearing full suit and gear. Here, in the first 15-20 minutes, you will be briefed on the introduction and learning how to dive. You will also be taught the fundamentals of scuba diving and its safety precautions. The balance of the time will be utilized for the actual bottom time. This is a very safe lesson as the person will be 100% guided by a qualified instructor all the time in the confined water.
Apart from these, PADI® also offers many other courses. To see more of these dive courses, or to learn more about diving, go to PADI courses.
In my years of experience in diving, I have seldom encountered a person who is discouraged or uninterested in diving after his/her first discovery/scuba session. Their responses have always been... 'Do I start now?' and NOT 'I've had enough of it.'
