The Ultimate Scuba Diving Guide: Everything Beginners Need to Know From A-Z
Have you ever dreamed of feeling weightless, floating gently in the deep blue, surrounded by vibrant coral reefs and schools of colorful fish? That is Scuba Diving – a magical doorway to the underwater world, which covers over 70% of our planet.
If you’re curious and want to begin your journey of ocean exploration, this is the comprehensive guide for you. Amadive will walk you through every step, from the very first concepts until you’re ready for your first plunge into the sea.

Why You Should Try Scuba Diving at Least Once in Your Life
Scuba diving is more than just a sport; it’s a life-changing experience:
- Explore a whole new world: Experience the feeling of being an astronaut right here on Earth, witnessing a diverse marine ecosystem you’ve never seen before.
- Find absolute peace: Underwater, the only sound you hear is your own breathing. This silence is a meditative therapy, helping you leave all stress behind.
- Connect with nature: Meet beautiful sea creatures in their natural habitat, from adorable “Nemo” clownfish to gentle sea turtles.
- Join a global community: Become part of a worldwide community of ocean lovers.
First Step: How to Become a Diver?

For safety, you cannot simply go diving with a tank on your own. You need to be trained and certified by a globally recognized organization. The two most popular organizations are PADI (Professional Association of Diving Instructors) and SSI (Scuba Schools International).
The most common entry-level course is the Open Water Diver certification. The course typically consists of three parts:
- Knowledge Development: Learning the fundamental principles of safety, equipment, and the diving environment.
- Confined Water Dives: Practicing basic dive skills in a swimming pool or a shallow, calm body of water.
- Open Water Dives: Applying what you’ve learned in actual ocean dives under the supervision of an instructor.
