Freediving Guide

Freediving means diving underwater on a single breath without breathing equipment. It is not only about depth or records; it also develops relaxation, efficient movement, and awareness of your body and the underwater environment.

Less equipment does not mean less preparation. Safe practice requires training in breathing preparation, equalization, buoyancy, surface recovery, buddy supervision, and rescue procedures.

The activities may share some equipment, but their goals and skills differ.

• Snorkeling mainly involves breathing at the surface while observing below, with occasional shallow duck dives.
• Freediving teaches relaxation, efficient movement, equalization, and safety procedures for structured breath-hold dives.
• Scuba diving uses a tank and regulator for continuous breathing while managing buoyancy and breathing gas.

A scuba certification does not automatically teach freediving breathing or buddy procedures, so take separate introductory freediving training.

The scope varies by training agency and course, but beginner training commonly includes:

1. Theory: Understand pressure, basic breath-hold physiology, equalization, equipment, and freediving disciplines.
2. Dry practice: Practice relaxed breathing, preparation, and surface recovery procedures.
3. Pool or confined water: Develop static breath-hold, horizontal swimming, finning, buddy supervision, and rescue skills.
4. Open water: Use a line and buoy to practice descents, ascents, equalization, and buddy procedures.

Controlled technique and knowing when to stop come before depth or breath-hold targets.

Loss of consciousness can occur even in shallow water, so the most important rule is never freedive alone. A person simply being nearby is not enough: a trained buddy must watch each dive and be close enough to respond immediately.

• Do not hyperventilate in an attempt to extend a breath-hold.
• Follow a buddy system where one person dives and the other is dedicated to safety.
• Share the dive plan and recovery interval, progress gradually, and stay within your training.
• Use appropriate weighting and buoyancy; do not turn depth or time into an informal competition.
• End the session when illness, fatigue, discomfort, or pain affects you.

Buddy and rescue skills cannot be learned from text alone. Learn them from a qualified instructor and practice them regularly.

As you descend, the pressure difference around your ears and sinuses increases. Equalization manages that pressure so you can descend comfortably.

Learn to equalize gently and early rather than waiting for pain and then forcing it. If equalization does not work or you feel pain, stop descending and return shallower. Do not push through congestion or cold symptoms.

Body position and depth can change which technique works well, so instructor feedback is more useful than copying a video without supervision.

A beginner course will often provide rental gear so you can learn what fits before buying.

• Mask and snorkel: Support clear vision and comfortable breathing at the surface; mask fit matters most.
• Freediving fins: Long blades provide efficient propulsion, but they work best with correct finning technique.
• Wetsuit: Provides thermal protection and changes buoyancy.
• Weight belt: Adjusts buoyancy for the suit and diver and should be configured under instructor supervision.

Correct fit, thermal protection, and safe buoyancy are more important than buying the most expensive equipment.

An introductory experience and a certification course cover different ground. Before booking, ask:

• Whether it is an experience or certification course and whether pool and open-water sessions are included
• Which swimming ability, minimum age, and medical-screening requirements apply
• Whether equipment rental, learning materials, and certification fees are included
• Teaching language, group size, and student-to-instructor ratio
• Expected depth, water temperature, waves, current, and visibility at the open-water site
• What extra practice is available if you do not complete a skill or assessment

For a first course, prioritize safety education, buddy and rescue practice, and time for questions over the advertised maximum depth.
