Divers are certified up to a maximum depth of 18 meters (60 feet) and receive a certification card that verifies their training level.

Advanced Open Water Diver

The Advanced Open Water Diver certification follows the Open Water Diver level and enables divers to increase their confidence and build upon their scuba skills. This course involves:

  • Deep diving and underwater navigation
  • Three additional adventure dives, which may include photography, buoyancy control, fish identification, etc.

Certification at this level allows divers to venture down to 30 meters (100 feet). The divers must also complete the specialty dives relevant to this certification.

Specialty Certifications

After the Advanced Open Water Diver level, divers may opt for Specialty Certifications to gain more specific skills and knowledge, which may include:

  • Wreck Diving
  • Night Diving
  • Underwater Photography
  • Search and Recovery

Specialty courses concentrate on particular aspects of diving, offering a detailed exploration of each topic. Divers often require multiple dives to become proficient in a specialty area, and such certifications can further enhance both safety and enjoyment underwater.

The Certification Process

The path to becoming a certified scuba diver is structured and comprehensive, ensuring divers are equipped with the necessary skills and knowledge for safe and enjoyable underwater experiences. Here is a breakdown of the certification process.

Knowledge Development

The initial phase is an in-depth theoretical course where students learn the principles of scuba diving. It often involves eLearning platforms like PADI eLearning, which provide flexibility to study at one’s own pace. Topics covered include:

  • Dive theory and safety practices
  • Equipment knowledge and its application
  • Dive planning essentials

Confined Water Dives

After mastering theoretical concepts, students progress to confined water dives, usually conducted in a pool or calm water with pool-like conditions. Here they:

  • Practice basic scuba skills
  • Learn to handle diving equipment
  • Perform various diving exercises to build comfort and proficiency underwater

Open Water Dives

The culmination of training occurs during open water dives where students apply what they have learned in an open water setting. Trainees are required to:

  • Perform a set number of dives (usually four)
  • Demonstrate competency in the skills practiced in confined water sessions
  • Experience real-world diving under direct instructor supervision


To obtain certification, students must pass an exam which tests their knowledge and understanding of key concepts, safety procedures, and problem management. The exam usually includes a written test and a practical test during a dive. This is to ensure that divers have the training and skills necessary to explore scuba dive safely and responsibly.

Essential Scuba Gear

Selecting the correct scuba gear is crucial for a safe and enjoyable dive. A diver must understand how each piece of equipment functions and its role in the diving system.

Personal Gear Selection

When choosing personal gear, divers should prioritize fit and comfort. A well-fitting mask is pivotal; it should form a proper seal without being too tight. Fins should match the diver’s kicking style and the conditions they will be diving in. For thermal protection, a wetsuit that suits the water temperature is essential, as it provides insulation and aids in buoyancy.

  • Mask: protects your eyes & nose and lets you see clearly.
  • Fins: Lets you swim faster with less effort.
  • Wetsuit: Provides warmth and buoyancy.

Understanding Scuba Systems

The scuba system is made of several key components that enable breathing and control underwater. A buoyancy control device (BCD) allows divers to adjust their buoyancy as needed to help them ascend, descend, or maintain neutral buoyancy. The regulator is vital as it delivers air from the scuba tank to the diver at a breathable pressure. A dive computer is instrumental for monitoring depth, time underwater, and decompression status.

  • Buoyancy Control Device (BCD): Adjusts buoyancy.
  • Regulator: Delivers air from the air tank.
  • Dive Computer: Tracks dive parameters.
  • Scuba Tank: Stores compressed gas.

Each piece of equipment is integral to a diver’s safety and the overall diving experience.

Choosing the Right Dive Center

When selecting a dive center, a diver’s safety, the quality of training, and the type of certification offered are critical. It’s important to choose a facility that meets your specific needs and ensures a high standard of diving education.
