While not a scuba certification course, Try Scuba Diving and PADI Discover Scuba Diving is a quick and easy introduction to what it takes to explore the underwater world. 

To breathe underwater for the first time – what a feeling! This is simply incomparable! You have to get used to it at first. After all, people are not made for it normally. After a few minutes of quiet breathing under water, most participants realize how easy diving can be. To stay calm and to follow the instructions of your PADI Instructor are the first prerequisites to complete the first diving exercises of your life. If that works after a few minutes, most of the participants are really enthusiastic and never forget that first impression under water.
