If you want to get a scuba diving certification nj, you need to get a diving course with some prerequisites. These requirements involve the following: a simple swimming test, studying modules to learn what to do, practicing the theory learned in a confined pool, practicing in open water and experiencing a dive which is typically 18 meters, and a course examination at the end.
At the beginning, you will be expected to undertake a short swim and then to treat water for a while, but this varies from agency to agency. The PADI requirement, for example, is to swim for 200 meters and then treat water for 10 minutes. There are no required strokes though. And the speed and other things are also not stipulated. Basically, all you need is to be able to swim 200 meters and then stay afloat for around 10 minutes.
In the part where you need to study theory, there are various modules that you can study. And, you can study these modules at a dive center, online, or at a local scuba diving classes nj. In these modules you will be taught how to set up your equipment, the functions of each equipment, safety procedures, how to clear your mask and regulator underwater, different entry and exit methods, and a lot of other things. This may seem complicated but with a good instructor and materials to support the course, it can be something you can enjoy and get excited about as you head towards your first dive.
In pool training you put in practice what you have learned in theory. This starts from setting up your gear to the basics of navigation and the safety procedures such as sharing air with a friend. You will learn to breathe underwater, but this is all done in a comfortable shallow pool environment. Some people worry about breathing underwater, so this is a good opportunity to learn to do it properly.
The pool practice will then be tested in real open water. You will enter the open water which is the sea or a quarry, and practice mask clearing and so on. You will then undertake a series of 4 dives, each one deeper than the last. After each, you will log the dive and practice making the required surface interval calculations. When you have done your fourth dive, you be probably be around 18 meters, so that you have experienced the maximum depths to which you are qualified to dive.
