The recreational method is a course, a warm-up breathe-up that is not hyperventilation, a duck-dive, equalisation, and a recovery breath in front of a watching buddy.
Depth for its own sake is the sport pathway. Looking at a reef on one breath is the holiday pathway. They share a safety culture.
Steps
- Take a proper course
Equalisation, duck-dive, and rescue basics. Hotel “try freedive” is a taste, not a qualification.
This atlas is not the course.
- Never dive depth alone
A surface safety or in-water buddy is the control.
Solo spearfishing cultures exist and still write the same obituaries.
- Warm up, do not hyperventilate
The safety chapter explains why the old “blow off CO2” trick is a blackout setup.
A comfortable first dive is 5–8 m, not a personal best.
- Equalise early
Frenzel or the taught method. Turn at the first failure.
Forcing ears is how people buy a clinic week.
- Turn with reserve
The easy ascent is the point. Struggle at the bottom is a bad plan.
A line or a known wall helps.
- Recover in front of the buddy
Hook breaths, stay at the surface until the brain is clearly back.
Walking straight to the towel is how shallow-water blackout gets missed.
Skills
- Equalisation — The limiter for most people, not lung size.
- Duck-dive — Efficient, quiet, coral-safe.
- Relaxation on the way down — Soft face, soft hands.
- Turn discipline — A number or a feeling agreed in advance.
- Buddy rescue basics — A course skill, not a YouTube skill.
Progression
- Snorkel comfort — Then a first 5–8 m duck-dive.
- AIDA 1 / SSI L1-type band — Often to about 12–20 m with a buddy.
- Line diving in a club — Depth as sport.
- Elite categories — A tiny minority.
Common mistakes
- Hyperventilation — A classic blackout setup.
- Solo personal bests — The sport’s worst tradition.
- Scuba-style equalisation only — May not be enough; learn Frenzel in a course.
- Chasing a GoPro depth — The camera is not a safety diver.
The method is a buddy and an early turn. Depth is optional; the recovery breath is not.
