EQ Trainer 2 – Your compact equalization trainer for anywhere

The EQ Trainer 2 is the improved version of the trusted tool used by freedivers to enhance equalization skills. Whether you're learning the Frenzel technique or refining your Mouthfill and Reverse Packing, the EQ Trainer 2 lets you train anywhere, anytime. This compact device is ideal for dry training without needing access to water.

One-handed use for full control

With its newly added notch, the EQ Trainer can be held with one hand: place it between your thumb and fingers, pinch your nose, and use your free hand to check if your abdominal muscles or intercostal muscles are relaxed. This ergonomic design makes your training even more effective.

Individually adjustable airflow

One of the main features of the EQ Trainer 2 is the adjustable airflow. You can fine-tune the resistance, measure your progress, and target your weaknesses. Ideal for structured freediving training routines.

Train whenever and wherever you like

Weighing only 15 grams and measuring just 4.5 cm in length and 2.2 cm in diameter, the EQ Trainer 2 fits easily into any pocket. Use your lunch break or spare moments for a quick training session – your reliable tool for everyday practice.

Skin-friendly materials & smart design

Made from hypoallergenic ABS plastic, the EQ Trainer 2 is suitable for sensitive skin. It includes two latex balloons (non-hypoallergenic). Specifically designed for freedivers, it provides realistic feedback during pressure-based exercises.

Easy to clean & maintain

Before first use, wash the EQ Trainer 2 with soapy water and apply disinfectant spray. Let all parts dry completely before assembly. After each session, repeat this process. To ease tightening and loosening, apply silicone to the threading. Avoid extreme temperatures (below -40 °C or above 50 °C) and do not drop onto hard surfaces.
