• Certified AIDA 3 or equivalent freedivers ready for master level training
• Divers aiming to reach 38 meters with precision and control
• Athletes preparing for competitions or professional pathways
• Freedivers who want advanced rescue leadership and deep safety competence
• Those ready to transition from skilled diver to confident dive leader

We build mastery through understanding.

Your theory development explores the science, physiology, and training principles behind deep freediving, while strengthening the knowledge required for responsible dive leadership.

You will study:

• Advanced physics of pressure and gases, including Boyle’s, Dalton’s, and Henry’s laws
• Lung mechanics, failure depth, and strategies to improve vital capacity and flexibility
• FRC diving, mouth fill equalization, packing, and reverse packing, including use, benefits, and risks
• Decompression stress, surface intervals, and advanced deep safety considerations
• Aerobic and anaerobic conditioning, stretching, and long term training structure
• Nutrition and recovery strategies that support high level performance
• The assistant instructor role, supervision principles, and safe group management

This is where depth becomes understood, not assumed.
Every concept is applied directly in training and leadership practice.

In confined water, the focus shifts toward performance quality, coaching awareness, and rescue leadership.

You will practice:

• Planning and leading warm ups and static sessions for other divers
• Static apnea performances of 3:30 or longer with full safety control
• Designing and executing structured dynamic training sessions
• Demonstration level dynamic apnea of 70 meters or more
• Acting as safety diver for maximum dynamic attempts
• Advanced rescue procedures for LMC and blackout, including pool extraction and coordinated team response

Confined water becomes a space for precision, responsibility, and leadership under controlled conditions.

During multiple deep training sessions, you will integrate technique, safety, and leadership in real diving conditions.

You will practice:

• Leading warm ups, stretches, and full open water dive preparation
• Independent setup and management of lines, knots, bottom weights, and safety systems
• Practicing FRC dives and mouth fill equalization in controlled progression
• Deep safety skills including mask off ascents, one fin ascents, and rescues from depth
• Towing and managing an unconscious diver at the surface with rescue breathing
• Performing Variable Weight dives in a structured learning environment
• Executing Constant Weight dives to 32 to 38 meters using refined equalization and freefall
• Supporting instructors and supervising other divers in real training scenarios

Open water becomes a space where mastery, responsibility, and leadership come together.

Depth means nothing without responsibility.

As part of your theory training, you will complete a dedicated environmental module focused on becoming a responsible freediver. Because performance without awareness has no place in the ocean.

You will learn:

• The fundamentals of marine ecosystem awareness
• The importance of Posidonia oceanica and why seabed contact matters
• How finning technique and buoyancy affect fragile habitats
• Respectful interaction guidelines for marine life
• Local environmental considerations specific to the Messinian Gulf
• How to assess shared water space with boats and other users
• Sustainable equipment and consumption choices
• Daily habits that reduce your environmental footprint as a diver

This module is not optional.
It is part of what defines a real freediver.

At Alchemy Freediving Center, responsibility toward yourself and responsibility toward the ocean are inseparable.

Your AIDA 4 program is comprehensive, demanding, and master level. Every component is designed to refine deep technique, elevate safety leadership, and prepare you for professional level responsibility.

Across five immersive training days, you receive:

• Professional coaching from an experienced certified AIDA Instructor
• Advanced master level theory covering deep physiology, pressure physics, and performance principles
• Structured confined water performance sessions and rescue leadership training
• Multiple deep open water sessions progressing toward 38 meters
• Practical training in mouth fill, FRC diving, packing, and refined freefall technique
• Deep safety leadership and complex rescue scenario practice
• Introduction to assistant instructor responsibilities and diver supervision
• Access to premium freediving equipment throughout the program
• Diving insurance coverage for the full course duration
• Full access to our training lines, classroom space, and professional facilities
• Digital course manual and continued training guidance
• International AIDA 4 certification upon successful completion

This is where depth, safety, and leadership integrate into true mastery.

By the end of AIDA 4, you will have:

• Completed structured deep dives up to 38 meters
• Mastered advanced equalization strategies including mouth fill and FRC techniques
• Refined freefall control, buoyancy awareness, and energy efficiency
• Developed deep rescue leadership and complex safety management skills
• Strengthened dive planning, supervision, and assistant instructor awareness
• Earned your AIDA 4 certification

More importantly, you leave with authority.

Authority in your technique.
Authority in your decisions.
Authority in how you lead and support others in the water.

We train in calm conditions, in small groups, with full attention on each student.

Progress happens at your pace.
Confidence grows naturally.

You are not compared to anyone.
You are guided toward your own capacity.

AIDA 4 is not about depth alone.

It is about mastery.

It is about refining every detail that allows deep dives to feel controlled, efficient, and deliberate. It is about understanding the science behind performance, strengthening safety judgment, and developing the calm authority required to lead in the water.

You move beyond being a capable diver and step into responsibility.
Every dive is intentional.
Every decision carries weight.

This is where technique becomes mastery.
Where safety becomes leadership.
Where depth is managed, not chased.

You are not trained to push limits.
You are trained to embody them.
