How to Start Freediving - A Practical Beginner Guide

Freediving has a steeper learning curve than it appears from the outside — not because the skills are hard, but because the order you learn them matters significantly for both safety and progression.

A certified beginner course (AIDA 2, SSI Level 1, or equivalent) covers:

• Freediving physiology — what actually happens during a breath hold
• Equalization technique — the skill that determines your depth ceiling
• Duck dive and descent technique
• Breathing preparation and recovery
• Buddy rescue protocols — how to respond if someone blacks out
• Safety rules and risk factors

Trying to learn from YouTube skips the practical feedback from an instructor watching your technique — and critically, skips the buddy rescue training that should be foundational.

Cost

$150–350

Duration

1–2 days

The minimum beginner kit

Long-blade freediving fins

standard snorkeling fins don't work for vertical diving

Low-volume mask

important for equalization efficiency at depth

Simple snorkel

J-tube design, no purge valves

Wetsuit

matched to your water temperature (3mm warm, 5mm mild, 7mm cold)

Weight belt and lead

to achieve correct buoyancy with a wetsuit

What to skip for now

• Carbon fiber fins — not until technique is consistent
• Open-cell wetsuit — too delicate for beginners
• Full freediving computer — a depth gauge watch is enough to start

Pool sessions give you what open water can't:

Controlled environment

no current, surge, or visibility concerns

Easy buddy access

your buddy is right there at all times

Repeatability

practice the same skills again and again without variables

Lower stress

which means better technique learning

What to practice in the pool

1. 01 —Duck dive until it's automatic — head down, arms along the body
2. 02 —Equalization at 1m, 3m, 5m — test before adding depth
3. 03 —Descent position — streamlined, minimal drag
4. 04 —Recovery breathing — exhale first, three breaths, OK signal, every time

When duck dives are clean and equalization is reliable at 5m, move to open water.

Find a training partner who has completed a beginner course, or who understands freediving safety. The protocol is non-negotiable:

1. 01 —One diver dives — one watches from the surface
2. 02 —The surface diver watches continuously — eyes on the diver the entire time
3. 03 —Diving diver surfaces and gives OK signal
4. 04 —Three recovery breaths before next dive
5. 05 —Minimum surface interval: twice the dive time

Both divers should know rescue breathing and how to support an unconscious diver at the surface — covered in beginner courses.

Only add depth when you're comfortable and consistent at your current depth. Comfortable means:

• Equalization is automatic and pain-free
• Duck dive and descent are clean without correction
• You're surfacing with a clear margin — not gasping
• You could comfortably turn around 2m earlier if needed

Add 2–3m at a time. That's it.

Individual variation is significant. Track your own progression, not someone else's.
