When you are visiting a dive center, ask to sign up for the PADI发现水肺潜水（DSD）course. The DSD course is a one day intro to scuba diving experience.
The course includes classroom work covering basic skills and safety, followed by skills practice in a pool or confined water, followed by an open water dive. After the dive, if you love the experience you can enroll in a full course and apply your first dive to any PADI Open Water or PADI Scuba Diver course.
2. Practice your skills第一的in a pool or confined water
