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. Whether you're just getting started in the water or have been diving for several years, PADI certifications are a great way to get a feel for diving.
