Molchanovs EQ Trainer 2.0 – Freediving Equalization Trainer

Molchanovs EQ Trainer 2.0 – Improve your equalization technique

The Molchanovs EQ Trainer 2.0 is a compact training tool for freedivers who want to improve their equalization technique in a structured and controlled way. Whether you are learning the basics of Frenzel equalization or working on more advanced techniques such as Mouthfill and Reverse Packing, the EQ Trainer 2.0 allows you to practise dry, almost anywhere.

Equalization is one of the most common limiting factors in freediving. The better you understand and control the movement of your tongue, soft palate, glottis and breathing muscles, the more relaxed and reliable your dives can become. The EQ Trainer 2.0 helps you build awareness, control and repetition outside the water.

Why equalization training matters

A relaxed and consistent equalization technique is essential for safe and enjoyable freediving. Many equalization issues are not caused by depth itself, but by tension, lack of awareness or inefficient movement patterns. With regular dry training, you can practise these movements in a calm environment and build better control before applying them in the water.

The EQ Trainer 2.0 is especially useful for short, frequent training sessions. A few focused minutes can help you understand your technique better and make your equalization more stable and repeatable.
