Freedive safety
Read first Water sports carry drowning, pressure and medical risks. Use certified instruction, check conditions, and never treat depth or time tables as personal clearance.
How to use this guide Match skill to site Start in controlled water, then add current, depth and night only with training.Verify agency path PADI, SSI, CMAS and national programs differ on medical and depth rules.Expert voices Conditions beat gear: abort early when visibility, current or buddy signals change. Dive instructor — Site briefings Quick answers Do I need a medical form? Most agencies require a questionnaire or physician clearance before confined or open-water training.
How do seasons affect sites? Visibility, current, temperature and wildlife access change by month — check local charts and operators.
Key data Band Teaching use Depth band Agency training limits — not a personal clearance. Visibility Site and season dependent; abort when buddy contact is lost.

Can I copy a site’s depth for my plan? Treat listed depths as teaching envelopes. Real plans need charts, guides and conditions that day.
Buddy requirement? Recreational systems usually train with a buddy. Solo requires extra training and local permission.

Freediving is intentional breath-hold diving: a duck-dive to look at a reef, a line dive in a competition, or a spearfishing working breath. AIDA and CMAS write sport rules. Recreational depths for trained club divers often sit around 10–20 m; elite constant-weight records are another world.
Skill ceiling and risk sit high in this atlas. Gear load is low — a long-blade fin, a mask, a wetsuit. Accessibility is middling because a proper course and a safety buddy are the entry, not a hotel snorkel.
This chapter is not a certifying agency, not a live line-dive plan, and not medical advice. The freedive-safety chapter is the sibling that should be read first if the goal is depth.
Educational atlas, not a certifying agency and not medical or rescue advice. Local parks, skippers and instructors have the last word on conditions.

Frequently asked questions Which local rescue or training agency should I check first? Use the local lens: coastguard/federation norms and the shop briefing for that bay — not a blog visibility claim.
What is AIDA? The International Association for the Development of Apnea, a major sport and education body for competitive freediving.
How deep do recreational freedivers go? Many club divers spend years in the 10–20 m band. Depth is not a personality.
Is a course required? Not by most beaches. It is required by anyone who wants a safety culture. This page is not a card.
What is shallow-water blackout? A loss of consciousness from hypoxia, often near the surface on the way up. The safety chapter covers the culture; this is not a medical text.
Can scuba divers just freedive? Equalisation and lungs work differently. A scuba card is not a freedive education.
Spearfishing? A related working breath-hold culture with its own laws. This chapter is the dive craft, not a hunting licence.
Medical advice? No.
