Two-Day Freediving Course in Sofia – AIDA 2, Part 1

Take a first step into breath-hold diving with a two-day freediving course in Sofia: AIDA 2, Part 1. Freediving means going underwater while holding your breath, without scuba breathing equipment. A mask, snorkel, fins and the air you breathe in before diving take the place of a tank, while preparation brings the body and mind together.

The course description connects this skill with exploring the sea and diving to depths of 15–20 metres. These depths describe a possibility within freediving, rather than a guaranteed achievement for every participant during the two-day course in Sofia.

Breathing, relaxation and greater comfort underwater

You will be introduced to breathing techniques designed to help you develop your breath hold and work towards spending more time underwater in greater comfort. The training combines an understanding of the body’s responses with exercises in relaxation, pressure equalisation and efficient movement.

A qualified instructor accompanies you throughout the training. This is a group course with other participants you may not know, and the voucher described covers one person.

Theory training totalling 6 hours

The course includes two theory sessions with a stated total duration of 6 hours. Topics cover freediving physiology, breathing and breath-holding, pressure equalisation techniques and safety.

For the Sofia course, theory is taught remotely through live Zoom sessions. The stated time window for the online classes is 09:30–13:00. Confirm the exact allocation of sessions with the organiser, as the total theory duration is separately listed as 6 hours.

Practical training totalling 5 hours

The practical component consists of four sessions: one on breathing techniques, one on pressure equalisation, one on static apnea and one on dynamic apnea. Across a total of 5 hours, you will work on breathing and relaxation, extending breath-hold time, horizontal underwater swimming and efficient use of fins.

Static apnea involves holding your breath without moving, while dynamic apnea combines breath-holding with underwater movement. The exercises are part of instructor-led training, not an invitation to test your personal limits on your own.
