You will also learn to dive with a buddy of at least Open Water certification without the supervision of a dive professional. During your Open Water course, you'll practice all of these skills and maybe even a few extras. You should aim to master these skills to a point where you feel that you can carry them out with ease. Taking an Open Water Diving Course For scuba diving certification, you can take online courses on the theory portion from SSI or PADI. This can give you a head start before you enter the water to continue learning and demonstrating your open water skills in confined water training and then open water training. The in-water training can last three to five days for a course taught at dive destinations, or you can take a part-time course that lasts over the course of weeks or months.
