Ocean Safety: Freediving, Buddy Systems and Local Conditions

The principle behind everything

Freediving is a beautiful way to experience the ocean: quiet, unhurried and close to marine life. It is also an activity where small mistakes can have serious consequences. The answer is not fear; it is training, a trained buddy and conservative decisions.

This post does not replace instruction. It explains the principles you will hear from every good instructor, so you can recognise a responsible operator and plan a safer trip.

Never freedive alone

This is the rule that matters most. Freedivers can lose consciousness, often close to or at the surface, and sometimes without warning signs. A trained buddy watching from the surface is what turns a potentially fatal event into a manageable one.

• Dive one up, one down: one person dives while the other watches from the surface.
• Your buddy should watch you through the whole dive and for a period after you surface.
• Your buddy must be trained in freediving rescue, a friend who is “keeping an eye out” is not enough.

Use qualified instruction

Learn with a recognised training organisation and qualified local instructors. Good schools teach breathing, equalisation, recovery breathing, rescue and conservative progression. Many of the best freediving destinations (the Philippines, Bali’s Amed coast) have established schools.

Do not compete with depth or breath-hold

Holidays create a temptation to push: a new depth, a longer hold, a better photo. Resist it. Do not compete with your buddy, your previous best or anyone on social media. Progress gradually, within the structure of supervised training.

Do not hyperventilate

Hyperventilating before a dive is widely discouraged because it can mask the body’s signal to breathe and increase the risk of blackout. Use only the breathing techniques taught by your instructor.

Respect local conditions

Wind, current, swell, visibility, temperature and boat traffic all affect safety. Channels and passes, such as the atoll passes of French Polynesia or the Maldives, can carry strong currents.

• Always use a surface buoy and a dive flag where required.
• Stay away from boat channels and follow local rules.
• Cancel if conditions are poor. There is no shame in a rest day.

Look after your body

Rest, hydration, sleep and food all matter. Do not freedive if you are tired, unwell, cold or have been drinking. Avoid freediving immediately after scuba diving unless your instructor advises otherwise, and respect the guidance on flying after diving.

Respect marine life

Keep your distance from animals, never touch coral or wildlife and never chase encounters. Calm, patient freediving brings you closer to marine life than pursuit ever will.

The best freediving holiday

The best freediving holiday is the one where you come home with better technique and better memories, not a dramatic story about how close you came to trouble.
