What to Expect in Your AIDA 4 / SSI Performance Freediver Course

The course builds on your existing freediving experience and focuses on refining your technique, strengthening your safety skills and developing sound decision-making in more challenging open-water conditions.

Technique & Consistency

You'll refine your diving and breathing techniques to ensure they remain controlled and consistent even at greater depths.

The focus is on precise procedures, efficient movement and maintaining stability across multiple dives.

Safety & Responsibility

A key part of the course is learning to manage depth responsibly, apply effective buddy systems and follow clear safety procedures.


You'll learn to assess situations realistically and take responsibility for yourself and others.

Mental Stability

As depth increases, mental clarity becomes increasingly important.


The course helps you stay calm, make conscious decisions and maintain control throughout your dives – even in more demanding conditions.

The AIDA 4 / SSI Performance Freediver course lays the foundation for independent, mindful and responsible freediving at greater depths.

Depth Comes Through Technique & Control

The AIDA 4 / SSI Performance Freediver course isn't about simply diving deeper – it's about managing depth with control. As depth increases, technique, mental stability and precise procedures become increasingly important.

At greater depths, even small inaccuracies have a much greater impact than at advanced beginner level. This course helps you stabilize your procedures, control your movements more consciously and structure every dive clearly – from descent to a safe return to the surface.

Course Structure at a Glance

The AIDA 4 / SSI Performance Freediver course follows a structured learning process. Theory, pool training and open-water sessions are carefully integrated, allowing you to build your skills step by step.

The course is adapted to your individual level of development, previous experience and personal learning goals.

1. Advanced Theory & Preparation

We begin by deepening your theoretical understanding of freediving and introducing essential concepts for controlled diving at greater depths.

The focus is on safety awareness, decision-making, equalization, training principles and a responsible approach to diving – both for yourself and others.

2. Pool Training – Refining Your Technique

In the controlled environment of the pool, you'll further refine your technique, breathing rhythm and movement efficiency. The focus is on precise, controlled execution – without performance pressure.

Pool training helps you consolidate new skills in a safe environment before applying them in open water.

3. Open Water – Controlled Application

During the course, mouthfill is introduced as an advanced equalization technique and integrated into your diving practice. You'll learn when this technique is useful, how to prepare for it and how to apply it safely and with control.

The focus is not on maximum depth but on understanding, timing and precise execution, supported by clear descent and ascent procedures as well as safe buddy and rescue protocols.

4. Reflection & Integration

Between and after training sessions, we deliberately take time for feedback and reflection.

This allows you to reflect on your experiences, develop a deeper understanding of how different skills connect and integrate what you've learned into your diving practice.

This step is essential for developing long-term safety, independence and confidence in your freediving skills.

The course follows a clear structure while allowing room for individual adjustments, reflection and personal development at an advanced level.

Certification & Learning Objectives

The AIDA 4 / SSI Performance Freediver course follows clearly defined international training standards and is designed for freedivers who want to develop their skills to an advanced and independent level.
