Freediving Level Progression Guide for Hong Kong

A freediving level progression guide should help you choose a next training gate, not chase a headline depth. Start with recent experience, equalisation, buddy skills and recovery habits. Then compare AIDA 2, AIDA 3 and SSI routes against the skills you can demonstrate now. The worksheets turn that review into an enquiry brief. Course standards, medical suitability, dates and certification decisions must be confirmed with a qualified instructor and, where needed, a physician.

A useful fact to keep in mind

AIDA’s official standards list AIDA2 depth training to a maximum of 20 metres and AIDA3 depth training to a maximum of 30 metres; these are course-standard ceilings, not guaranteed personal depths.

What should a freediving level progression guide decide first?

How should this freediving level progression guide choose a next gate?

A sensible progression begins with a question: what do you need to do better on your next session? It might be calmer surface recovery or more consistent equalisation. It might also be better buddy coverage or a controlled return to depth after a break. A level is useful when its training addresses that need.

Do not treat AIDA 2 or AIDA 3 as guaranteed personal depths. AIDA’s official course page describes maximum training depths and certification demonstrations. An instructor still evaluates technique, conditions and readiness. The same principle applies when comparing the AIDA 2 vs AIDA 3 freediving routes.

The existing comparison is useful for the broad agency choice. This article adds a handover tool. Record what you can demonstrate, what remains inconsistent and what your next instructor must verify. That makes the progression conversation more precise than asking only, “How deep is the course?”

SSI uses its own sequence and recognition system. Its official pages describe a Freediver entry point and an Advanced Freediver programme. An SSI student should not copy AIDA labels into an SSI checklist. Compare the skills and evidence, then confirm the receiving centre’s current crossover or prerequisite process.

  • Name the purpose of the next level: technique, depth, safety, confidence or structured practice.
  • Separate a published course ceiling from the depth you are personally ready to attempt.
  • Bring a log of recent sessions, not only an old certification card.
  • Ask which performance, rescue and buddy demonstrations will be assessed.

When is AIDA 2 the right gate in a freediving level progression guide?

Use AIDA 2 to build a complete foundation

AIDA’s published AIDA2 outline includes theory, pool and depth work. It covers breathing physiology, equalisation, technique, equipment, safety and rescue. The published prerequisites include age and a 100-metre continuous swim, and no prior certification is required. These are entry facts, not a promise of identical progress.

For a first formal route, review the AIDA 2 Freediver course Hong Kong information. Then review the AIDA 2 freediving certification course Hong Kong pathway. Ask how the local sessions will be delivered.

If your target is the recognised 20-metre course ceiling, read the Hong Kong freediving 20m course details. Also read the AIDA 2 freediving course 20 metres Hong Kong details. Confirm the current schedule, ratios, equipment and assessment before payment.

AIDA’s course page lists AIDA2 demonstrations. They include a 40-metre bifin swim, a two-minute breath hold and a 12-metre bifin dive. They also include 10-metre buddying and a five-to-10-metre rescue. These figures describe the standard’s demonstrations. Approach them through progressive training, not self-testing or a solo depth attempt.

Use the worksheet below during your enquiry. A ‘developing’ row is valuable information: it tells the instructor where to spend pool time before an open-water plan. A qualified instructor may recommend more practice, a different pace or a medical review rather than forcing the published sequence.

  • Share any medical or ear-equalisation concern honestly before booking.
  • Ask whether the course includes pool, depth, theory and rescue components.
  • Treat a required review as a safety decision, not as a failed ambition.
  • Never convert a course maximum into a personal target for unsupervised practice.

When should an AIDA 2 diver consider AIDA 3?

Look for repeatable control before selecting the advanced gate

AIDA’s published AIDA3 prerequisite is AIDA2 certification or a crossover evaluation. Its syllabus adds deeper theory about barotrauma, lungs at depth, buoyancy, shallow-water blackout, training concepts and surface intervals. Depth sessions include Frenzel equalisation, freefall, buddying and rescue. The next level is therefore a broader capability step, not simply another depth number.

The official AIDA3 standard lists a 24-metre bifin dive, buddying and rescue. It also includes a 50-metre surface tow and self-rescue demonstrations. It also lists 55 metres of bifin underwater swimming and a 2:45 breath hold for certification. An instructor should coach these skills within the course plan and conditions.

Before asking about the AIDA 3 Advanced Freediver course Hong Kong, review whether your AIDA2 skills remain current. Can you equalise early and comfortably? Can you stay attentive to a buddy and recover without rushing? If not, a refresher or supervised practice may be the more useful next gate.

For the certification route, read the AIDA 3 freediver certification Hong Kong information. Request the local plan in writing. Ask about depth-session count, ratios, rescue practice, equipment and weather decisions. Also ask what happens when a skill is not yet consistent. A date is not a guarantee of certification.

  • Choose AIDA 3 when you want advanced equalisation, freefall and rescue practice, not only more depth.
  • Record your most recent supervised depth and the quality of your surface recovery.
  • Ask how a crossover evaluation handles a different agency background.
  • Leave enough time between demanding sessions to review technique and recovery.

How should SSI fit into your freediving level progression guide?

Match the SSI course to evidence, not to an AIDA label

SSI’s official Freediver overview describes an entry-level programme for buddy-supervised open-water freediving to 20 metres. Its Advanced Freediver page lists a minimum age of 15 and six logged Freediving sessions. It also requires Freediver or equivalent certification, four open-water sessions and a 30-metre maximum training depth. These are SSI details, not universal agency rules.

The useful comparison is what the next course asks you to demonstrate. A student may prefer SSI’s digital learning and recognition structure, while another may want AIDA’s named course gates. Neither choice removes the need for direct supervision, an appropriate buddy system, gradual adaptation and an instructor’s current assessment.

If you are moving between systems, give the centre your cards and logbook. Add recent session dates and any rescue or first-aid records. Ask which evidence is accepted and whether an evaluation is required. Do not assume that a matching number, a similar course title or a deeper published maximum means automatic crossover.

Use the decision matrix to prepare one clear question. It intentionally separates a route choice from a readiness decision. If two rows are unresolved, pause the booking conversation and ask the instructor what supervised practice would close the gap.

  • Keep agency requirements separate in your notes.
  • Count logged sessions with dates and conditions, not only personal-best depth.
  • Ask how the centre stores digital records and certification evidence.
  • Choose a programme whose supervision and teaching style you can realistically attend.

What safety checks belong between freediving levels?

Treat buddy coverage, recovery and health as progression evidence

DAN’s freediving guidance states that blackout is a real risk because breath holding reduces oxygen levels. It identifies direct buddy supervision as the primary safety rule. This should shape your progression plan. A personal best without reliable buddy coverage is not evidence that you are ready for the next level.

A useful log records more than depth or time. Note the instructor or buddy arrangement, warm-up, equalisation result, surface recovery, conditions and equipment. Record what you would change next time. Include whether the session was relaxed or rushed. These notes can reveal that lower-intensity practice is more valuable than a deeper attempt.

Never hyperventilate, train breath holds alone or push through ear pain. Stop when equalisation is painful or unreliable, and seek qualified guidance. A physician should address individual medical suitability. An instructor can explain the course’s general requirements, but cannot replace medical clearance.

A safety course may be the correct next step even when your depth has not changed. Ask about the freediving safety and rescue course progression conversation. Discuss buddy positioning, surface recovery, rescue sequence and practice conditions.

  • Plan every depth session with a trained, attentive buddy and a clear rescue role.
  • Use surface recovery quality as a gate, not an afterthought.
  • Stop for pain, panic, illness, congestion or unusual fatigue.
  • Review first-aid and emergency-response needs with a qualified provider.

How do you turn this freediving level progression guide into an enquiry?

Send a short handover that an instructor can actually assess

Start your message with your level, agency and last formal-training date. Add the number and type of recent sessions. Add your preferred month, pool or open-water goal, and whether you are considering AIDA or SSI. This gives the centre enough context to discuss fit before quoting dates.

Then ask the practical questions: Which prerequisite records are needed? What is the student-to-instructor ratio? How many theory, pool and depth sessions are planned? What equipment, venue and safety support are included? What written terms apply if weather, illness or readiness changes the schedule?

Unsure of your next course level? Use the which freediving course level should I take discussion as a prompt. Then send your own evidence.

Do not book solely because a course advert names a maximum depth. Choose the route whose prerequisites, supervision, teaching pace and safety practice match your current evidence. A slower decision can be the more useful progression because it leaves room for skills to become repeatable.

For a Hong Kong enquiry, send your completed worksheet to DiveHarbour on WhatsApp at https://wa.me/85294976438. Ask for dates and written terms. Confirm any medical question with a qualified physician and any certification decision with the active instructor.

  • Current certification and agency.
  • Recent sessions, conditions, equipment and logged experience.
  • Equalisation, recovery and buddy skills you want assessed.
  • Target course, preferred timing and alternative refresher option.
  • Questions about ratios, rescue practice, inclusions and rescheduling.

Questions to ask

Common questions

Does AIDA 2 mean I am guaranteed to dive to 20 metres?

No. The 20-metre figure is the published maximum training depth for AIDA2 standards, while individual progress depends on technique, equalisation, comfort, conditions and safety. A qualified instructor decides what is appropriate for your training.

Is AIDA 3 simply a deeper version of AIDA 2?

No. AIDA3 adds advanced theory, freefall and Frenzel equalisation, deeper buddying and rescue, surface tow and self-rescue demonstrations. Depth is one part of the progression; consistent safety and technique also matter.

Can I move from SSI to AIDA without an evaluation?

Do not assume automatic crossover. Provide your certification, logbook and recent-session evidence, then ask the receiving instructor which equivalence documents or evaluation apply under the current course standards.

Should I train breath holds alone to prepare for the next level?

No. Direct buddy supervision is a core freediving safety practice because blackout can occur. Never hyperventilate or force equalisation. Use qualified instruction and an attentive buddy for breath-hold and rescue training.

What if my certificate is current but I have not dived recently?

Tell the instructor about the gap. A refresher, pool practice or evaluation may be appropriate before depth training resumes. Certification status alone does not show current comfort, equalisation or rescue readiness.
