AIDA 4 MASTER FREEDIVER / ASISSTANT INSTRUCTOR

AIDA 4 — Master Freediver

Take your freediving to the next level.

AIDA 4 is the highest level in the AIDA recreational freediving pathway and is designed for experienced freedivers ready to develop greater depth, stronger technique and a deeper understanding of the skills and knowledge behind advanced freediving.

This is much more than simply learning to dive deeper. Throughout the course, you’ll develop your understanding of advanced equalisation, deep diving physiology, training methodology, breathwork, safety and performance. You’ll also learn how to analyse your own diving, structure effective training and support other freedivers in their development.

What you'll explore

• Advanced depth diving and deep-water technique

• Mouth-fill equalisation and advanced equalisation strategies

• FRC diving and the physiological demands of deep diving

• Constant Weight and Free Immersion techniques

• Advanced static and dynamic apnea training

• Freediving-specific strength, mobility and conditioning

• Breathing preparation and respiratory training

• Training planning, recovery and performance optimisation

• Advanced rescue, safety and open-water procedures

• Dive-line, lanyard and deep-water equipment setup

• Video analysis and technical refinement

• Supporting and mentoring other freedivers

The AIDA 4 experience

At Drifters, we see AIDA 4 as an opportunity to bring all of your previous experience together and develop a much deeper understanding of your diving.

You'll work on refining technique, identifying individual limitations and building the knowledge and confidence required to dive deeper and train more effectively. We place a strong emphasis on understanding why things work, rather than simply following a set of instructions.

You'll also develop the ability to contribute to the development of other divers, including assisting with training sessions, warm-ups, open-water preparation and supervised freediving activities.

Certification requirements

To complete AIDA 4, you'll need to demonstrate the required theoretical knowledge and practical skills, including:

• 3:30 static apnea

• 70 m dynamic apnea with fins

• 32 m constant-weight freedive

• Successful completion of the AIDA 4 theory examination

AIDA 4 is an advanced qualification and requires a strong foundation of previous freediving experience, appropriate preparation and a mature approach to training and safety.

Ready to become a Master Freediver?

AIDA 4 is about more than achieving a number on a dive line. It's about becoming a more knowledgeable, capable and self-sufficient freediver—and developing the skills to help others become better divers too. People who complete AIDA 4 can become Assistant Instructors on freediving courses.
