A PADI certification is a good option if you are looking to become a certified diver. There are many levels of PADI training available. The course typically includes three components: an online selfstudy module to learn the basics of diving theory; confined water diving to enhance your equipment comfort; and open water dives to put what you have learned into practice. You can get a good feel for diving, whether you are just starting out or an experienced diver.
