Your certification is a license to learn, and completing this course is only the beginning of your development as a scuba diver. You can increase your knowledge and skills by participating in advanced or specialty dive courses. These courses increase your safety and enjoyment of the sport by exposing you to new conditions and activities. You will learn about these courses during the final chapter, "Continuing Education."

Experience is just as important as formal training. Joining local dive clubs helps you meet divers with diverse experiences and interests, while also introducing you to new friends. You can also hire an instructor or divemaster for guided tours and site-specific orientations.
