SSI Freediving: Courses, Levels, Certification & Training Guide

SSI Freediving: Courses, Certification Levels and What to Expect

Holding your breath underwater sounds simple until you actually try to do it properly.

At first, most people focus on one thing:

How long can I stay down?

Then you take a real freediving course and discover there is much more going on.

Relaxation matters. Equalization matters. Technique matters. Your position in the water matters. How you recover at the surface matters. And knowing what to do when your buddy needs help matters considerably more than adding another ten seconds to your personal record.

That is where SSI freediving training comes in.

SSI, or Scuba Schools International, offers a structured freediving education system that begins with introductory pool-based training and progresses through recreational open-water certification, advanced depth training and eventually performance-level freediving.

As of 2026, SSI’s main recreational pathway includes Basic Freediver, Pool Freediver, Freediver, Advanced Freediver and Performance Freediver, alongside specialty programs for divers who want to explore particular techniques or disciplines. Divessi Training

And no, you do not need to arrive capable of diving 40 meters.

That would rather defeat the purpose of training.

What Is SSI Freediving?

SSI freediving is the freediving education system developed by Scuba Schools International.

Instead of learning through random breath-hold attempts or copying techniques from social media, students progress through structured theory, confined-water sessions, open-water training and safety exercises.

Depending on the level, training can include:

Breathing and relaxation
Freediving physiology
Static apnea
Dynamic apnea
Duck diving
Finning technique
Streamlining
Equalization
Free immersion
Constant weight diving
Surface recovery
Buddy procedures
Rescue skills
Training planning
Freefall
Advanced equalization
Performance preparation

The point is not simply to make you dive deeper.

SSI describes its recreational certifications as preparing freedivers to practice safely and autonomously with an equally or more qualified buddy, within environments and depths appropriate to their training. Divessi Training

That buddy part is important.

Getting certified does not unlock solo freediving mode.

What Does SSI Stand For?

SSI stands for Scuba Schools International.

Despite the word Scuba in the name, SSI has developed training systems covering several underwater disciplines, including scuba diving, freediving and mermaid programs.

SSI courses use digital educational materials and certification records through the MySSI system. Students create a profile and can access course materials, certifications and logged sessions through the website or MySSI app. Divessi

This can be particularly convenient for travelers.

Your certification card does not need to live in the mysterious drawer where physical dive cards historically went to disappear.

SSI Freediving Levels Explained

The SSI pathway is progressive.

You do not jump directly into performance freediving because you once stayed underwater for a surprisingly long time in a hotel pool.

Each level adds experience and skills.

SSI Level	Minimum Age	Suggested Duration	Maximum Training Depth	Main Purpose
Basic Freediver	10	6–8 hours	5 m confined water	Introductory experience
Pool Freediver	12	12–14 hours	5 m confined water	Pool-based certification
Freediver	12	16–20 hours	20 m	Entry-level open-water certification
Advanced Freediver	15	24–30 hours	30 m	Greater efficiency, depth and independence
Performance Freediver	18	32–40 hours	40 m	Highest non-professional SSI freediving course

These are training limits, not promises that every student will reach the maximum depth. Certification depends on completing the required knowledge, skills and performance standards rather than simply attending the scheduled classes. Divessi Training

SSI Basic Freediver

The SSI Basic Freediver program is designed as an introduction to recreational freediving in a pool or confined-water environment.

It is technically a recognition program rather than the full SSI Freediver certification.

SSI currently sets:

Minimum age: 10
Recommended duration: 6–8 hours
Maximum depth: 5 meters
Environment: pool or confined water

The program introduces the skills and knowledge needed to participate safely under professional supervision. Divessi Training

This can make sense if you are curious about freediving but not ready to commit to open-water certification.

Think of it as:

I want to understand what freediving actually feels like.

Not:

I have decided my new personality is descending vertically into the ocean.

Yet.

SSI Pool Freediver

The SSI Pool Freediver certification goes further while still keeping training inside pool or confined-water environments.

SSI currently recommends approximately 12–14 hours of training, with a minimum age of 12 and a maximum confined-water depth of five meters. Students complete academic work, a breathing session and at least two pool/confined-water sessions. Divessi Training

This route can appeal to people interested in:

Static apnea
Dynamic apnea
Pool training
Breath-hold technique
Freediving fitness
Learning safety without immediately moving into depth

Certified Pool Freedivers can practice independently with an equally or more qualified buddy in appropriate pool/confined-water environments within the scope of their training. Divessi Training

SSI also allows Pool Freediver students to upgrade later to the full Freediver certification by completing the required open-water sessions. Divessi Training

SSI Freediver: The Main Beginner Certification

For most people searching SSI freediving certification, this is the course they mean.

The SSI Freediver program is the main entry-level open-water certification.

Current SSI standards list:

Minimum age: 12
Six academic sessions
Two pool/confined-water sessions
Two open-water sessions
Recommended duration: 16–20 hours
Maximum training depth: 20 meters / 65 feet
No previous freediving certification required

Students must also be fit to swim and complete the required course assessments. Divessi

This is where freediving starts becoming much more than breath-holding practice.

You begin taking what you learned in controlled water and applying it vertically.

What Do You Learn in SSI Freediver?

The exact lesson sequence follows SSI’s training materials and instructor standards, but entry-level freediving education revolves around several core areas.

Breathing and Relaxation

Beginners learn that freediving preparation is not about aggressively inhaling and exhaling as much as possible.

Relaxation becomes a skill.

You begin noticing:

Shoulder tension
Jaw tension
Breathing patterns
Mental stress
Unnecessary movement

The calmer you become, the less energy you generally waste.

Static Apnea

Static apnea involves holding your breath while remaining still at the surface under appropriate supervision.

This helps introduce:

Relaxation
Breath-hold sensations
Buddy supervision
Recovery procedures

It is not a competition with the person beside you.

Especially on day one.

Dynamic Apnea

Dynamic apnea involves swimming horizontally underwater in a pool or confined-water environment.

This develops:

Streamlining
Fin technique
Efficiency
Body position

It is one thing to hold your breath while lying still.

It is another to move efficiently while doing it.

Open-Water Depth Training

Students then apply freediving techniques vertically using a line and buoy system.

Skills may include:

Duck diving
Constant weight
Free immersion
Equalization
Turns
Controlled ascent
Surface recovery
Buddy safety

This is often the point where freediving finally begins to feel like the activity that made you curious in the first place.

Blue water below you.

One breath.

Down you go.

How Deep Can You Go With SSI Freediver?

The current maximum training depth for SSI Freediver is 20 meters / 65 feet. For students aged 12–14, SSI limits open-water training to a maximum of 12 meters. Divessi

That does not mean everyone should immediately aim for 20 meters.

Depth depends on:

Equalization
Relaxation
Technique
Comfort
Physical condition
Instructor assessment
Environmental conditions

Some students progress quickly.

Others need extra time at shallower depths.

Neither situation means the course is going badly.

A comfortable 12-meter dive with good technique is far more useful than an ugly 20-meter dive achieved by fighting your body the entire way.

SSI Advanced Freediver

Once the fundamentals become comfortable, SSI Advanced Freediver moves toward greater efficiency, deeper diving and more sophisticated technique.

Current SSI standards list:

Minimum age: 15
SSI Freediver or recognized equivalent required
At least six logged freediving sessions
Three academic sessions
Two pool/confined-water sessions
Four open-water sessions
Suggested duration: 24–30 hours
Maximum training depth: 30 meters / 100 feet Divessi

At this level, the conversation begins changing from:

How do I descend?

to:

How do I descend efficiently?

What Do You Learn in SSI Advanced Freediver?

SSI specifically highlights skills such as freefall, improved equalization and planning safe freediving sessions within Advanced Freediver training. Divessi

Frenzel Equalization

As dives become deeper, equalization technique becomes increasingly important.

Many freedivers transition toward Frenzel equalization, which can be more efficient than techniques relying heavily on chest pressure.

Equalization often becomes the factor that limits beginner depth long before breath-hold time does.

Your lungs may feel perfectly fine.

Your ears have submitted a formal complaint.

Listen to them.

Freefall

At sufficient depth, increased pressure compresses air spaces and changes buoyancy.

Eventually, a diver can become negatively buoyant enough to stop kicking and allow gravity to carry them downward.

This is known as freefall.

Done correctly, it can feel remarkably peaceful.

For many freedivers, this is the point where the sport begins feeling less like swimming downward and more like actually diving.

Improved Dive Planning

Advanced training also places greater emphasis on organizing sessions, buddy systems and understanding how depth changes safety demands.

The goal is not only becoming a deeper diver.

It is becoming a more competent one.

SSI Performance Freediver

At the top of SSI’s non-professional pathway is Performance Freediver.

This is not a beginner course with a more impressive name.

Current prerequisites include:

Minimum age: 18
Advanced Freediver or recognized equivalent
At least 30 logged freediving sessions

The course currently includes:

Four academic sessions
Two pool/confined-water sessions
Five open-water sessions
Approximately 32–40 hours of training
Maximum training depth of 40 meters / 130 feet Divessi

SSI describes Performance Freediver as its highest non-professional freediving program. Divessi

What Makes Performance Freediver Different?

At this stage, training becomes much more performance-focused.

SSI’s current program includes topics such as:

Advanced pressure physiology
Performance preparation
Mouth-fill equalization
Equipment configuration
Advanced safety systems
FRC diving within defined training parameters
Coaching principles
Greater efficiency at depth Divessi

This is training for people who already freedive regularly.

If you have never learned Frenzel and have three total freediving sessions in your logbook, Performance Freediver is not your next weekend activity.

There are several useful steps in between.

SSI Freediving Specialties

SSI also offers specialty programs that let divers work on specific areas instead of only moving vertically through certification levels.

Current SSI training materials feature specialties including:

Monofin

Monofin training teaches efficient swimming using both legs together through a single fin.

The movement is very different from standard bifin kicking and requires specific technique through the core and body.

No-Fins Freediving

No-fins training removes the propulsion advantage of fins entirely.

This places greater emphasis on swimming technique and body efficiency.

Training Techniques

The SSI Training Techniques specialty focuses on understanding personal strengths and weaknesses and developing more structured freediving training. Divessi

These specialties can be useful because not every freediver’s next goal is simply:

Go five meters deeper.

Some want better technique.

Some love pool disciplines.

Some want to compete.

Some just discovered monofin swimming and have decided being human was overrated.

SSI Specialty Freediver, Progressive Freediver and Master Freediver

Here is one slightly confusing part of the SSI system.

Specialty Freediver, Progressive Freediver and Master Freediver are recognition ratings, rather than simply the next three depth courses after Performance Freediver.

SSI awards recognition as divers complete specialty programs and log additional freediving experience. Divessi

That distinction matters when researching courses.

Advanced Freediver is an actual training program.

Master Freediver is an SSI recognition rating earned through a combination of training and experience.

They are not interchangeable names.

How Fit Do You Need to Be for SSI Freediving?

You do not need to be an elite athlete.

You do need basic water competence.

SSI’s current water-fitness standards use different swimming assessments according to program level. Its published evaluation specifies:

Basic Freediver: 25 m swim
Pool Freediver / Freediver / Advanced Freediver: 100 m swim
Performance Freediver: 400 m swim

without swimming or buoyancy aids. Divessi Training

The purpose is not to see who is fastest.

It is to establish that the participant has an appropriate baseline of comfort and competence in water.

Freediving becomes considerably less relaxing if basic swimming is already stressful.

Do You Need to Be Good at Holding Your Breath?

No.

That is something you are learning.

People often postpone freediving because they test themselves at home, last 35 seconds and conclude:

Apparently I am biologically incompatible with freediving.

That is not how it works.

Untrained breath-holding and trained freediving are very different experiences.

Technique, relaxation, movement efficiency and mental comfort all affect how a dive feels.

Your starting breath-hold time is not a prediction of how good a freediver you can become.

SSI Freediving Safety Training

One of the biggest reasons to take a certification course is safety.

Freediving involves the possibility of hypoxia, loss of motor control and blackout.

This is why legitimate courses spend time teaching buddy procedures and rescue rather than simply helping students chase personal records.

SSI’s certifications are built around diving with an equally or more qualified buddy rather than freediving alone. Divessi Training

Training can include:

Proper supervision
Surface protocols
Recognizing problems
Rescue technique
Airway management
Recovery procedures
Safe session planning

The ability to rescue your buddy matters more than whether you can descend another three meters.

That is not the glamorous part of freediving.

It is the important part.

Can You Freedive Alone After SSI Certification?

No.

Certification does not make solo freediving safe.

SSI explicitly describes autonomous freediving in terms of diving with an equally or more qualified buddy within the conditions and depths of your training. Divessi Training

So “autonomous” does not mean:

Congratulations, you may now disappear into the ocean by yourself.

It means you no longer require direct instructor supervision when diving within the limits of your certification—but the buddy system remains fundamental.

SSI Freediving Equipment

Your exact equipment depends on the course and environment, but common freediving equipment includes:

Low-volume mask
Snorkel
Freediving fins
Wetsuit
Weight belt
Appropriate weights
Dive computer
Freediving buoy
Line
Bottom weight
Lanyard where required

Beginners do not necessarily need to buy everything first.

Rental equipment is useful while discovering:

What fin stiffness works for you
Which mask actually fits your face
What wetsuit thickness you need
Whether you prefer bifins or eventually want a monofin

There is no prize for arriving at your first freediving class with more equipment than your instructor.

How Long Does SSI Freediving Certification Take?

SSI publishes course duration in recommended training hours rather than simply promising that every course takes exactly two or three days.

That is sensible because student progress varies.

The current recommendations are approximately:

Course	Suggested Training Time
Basic Freediver	6–8 hours
Pool Freediver	12–14 hours
Freediver	16–20 hours
Advanced Freediver	24–30 hours
Performance Freediver	32–40 hours

Training centers may distribute those hours differently.

A vacation-based course may be concentrated into several days.

A local school might spread sessions across multiple weekends.

Certification should depend on completing the requirements, not simply the calendar reaching Sunday afternoon.

How Much Does an SSI Freediving Course Cost?

SSI does not publish one universal worldwide course price.

Its own training information explains that costs are determined by the selected training center and may be packaged differently. Components can include:

Digital training materials
Academic tuition
Pool/confined-water training
Open-water sessions
Certification fees Divessi

Your total cost may also depend on:

Equipment rental
Boat fees
Pool entry
Cenote or park entrance
Transportation
Additional training sessions

This means comparing two prices only makes sense after checking what each one actually includes.

A cheaper course stops looking cheap when equipment, entry and open-water fees appear separately later.

SSI Freediving vs. AIDA

SSI and AIDA both provide structured freediving education, but the naming systems differ.

SSI’s own equivalency chart currently places its major programs alongside recognized certifications from AIDA and other agencies.

For example, SSI lists:

SSI	AIDA
Pool Freediver	AIDA 2 Pool
Freediver	AIDA 2
Advanced Freediver	AIDA 3
Performance Freediver	AIDA 4

That does not mean the curricula are identical in every detail.

It means SSI recognizes these levels for training-equivalency purposes.

For most recreational divers, the instructor and quality of training matter more than becoming emotionally attached to one logo before you have even taken your first course.

SSI Freediving vs. PADI Freediving

Both organizations offer internationally recognized underwater training systems, but their course structures and names are different.

SSI organizes its main open-water progression around Freediver, Advanced Freediver and Performance Freediver.

PADI uses its own freediving pathway and requirements.

If you already hold a certification from another recognized agency and want to cross into SSI, do not assume you must automatically restart at the beginning. SSI maintains equivalency standards for recognized training organizations. Divessi Training

The training center can evaluate your existing qualification and tell you which course fits next.

Is SSI Freediving Certification Recognized Internationally?

SSI operates an international training system with centers in destinations around the world, and certifications are stored digitally through MySSI. SSI also maintains formal equivalency tables for certifications from multiple other recognized freediving agencies. Divessi Training

Practically, however, whenever you arrive at a new freediving center, expect the operator to consider more than the name on your card.

They may also ask about:

Recent experience
Logged dives
Maximum comfortable depth
Time since your last training
Current equalization ability
Local conditions

A certification proves training.

It does not prove that you practiced yesterday.

SSI Freediving in a Pool

Pool training gives beginners a controlled environment.

No waves.

No current.

No boat movement.

You can focus on:

Breathing
Relaxation
Static apnea
Dynamic apnea
Streamlining
Buddy skills

SSI even offers the dedicated Pool Freediver certification for people who want to remain within confined-water disciplines before moving into open water. Divessi Training

For many people, this removes a lot of unnecessary stress at the beginning.

You can learn what your body is doing before adding the ocean’s opinions.

SSI Freediving in the Ocean

Open water changes the experience completely.

Now you have:

Depth
Waves
Current
Visibility changes
A vertical line
Greater pressure changes

This is where equalization and relaxation become especially important.

The ocean also provides the thing that attracts many people to freediving in the first place:

The feeling of actually descending into open water.

A swimming pool teaches skills.

The ocean gives those skills somewhere to go.

Freediving in Cenotes

Mexico adds another training environment:

cenotes.

Selected cenotes can offer:

Clear freshwater
Calm surface conditions
Excellent visibility
Vertical depth
Dramatic rock formations
Protected environments away from ocean waves

They can be excellent locations for practicing vertical freediving when used appropriately and under qualified supervision.

MExplor currently offers cenote freediving training focused on relaxation, equalization, descent technique, turns and vertical water skills. MExplor Travel

And visually, there is a slight improvement over staring at swimming-pool tiles.

SSI Freediving in Mexico

Mexico is particularly attractive for freediving training because one trip can include very different environments.

The Mexican Caribbean offers:

Pools
Caribbean open water
Cenotes
Reef environments
Freediving excursions
Underwater photography
Snorkeling
Scuba diving

That allows travelers to combine formal training with the reason they probably wanted to learn freediving in the first place:

Actually exploring underwater.

Is SSI the Only Freediving Certification Option in Mexico?

No.

This is important if you specifically want to train with MExplor.

MExplor’s current public course listings primarily show AIDA certifications, including AIDA 1 and AIDA 3, alongside general freediving and cenote training. Its broader certification guide also explains that certification structures differ between training organizations. MExplor Travel

So if the letters SSI specifically matter to you, confirm the certifying agency with the center before booking.

If your goal is simply to receive recognized freediving instruction while traveling in Mexico, it makes sense to compare:

Agency
Instructor
Course level
Training environment
Included equipment
Number of sessions
Safety standards
Total price

The logo is only one part of that decision.

What Is the Best SSI Freediving Course for a Beginner?

For most people who want full recreational open-water training:

SSI Freediver is the natural starting point.

Choose Basic Freediver if you primarily want a short introduction.

Choose Pool Freediver if you want structured pool training without open-water depth.

Choose Freediver if you want the full beginner experience with both confined and open water.

A simple way to think about it:

Your Goal	Best Starting Point
“I just want to try freediving.”	Basic Freediver
“I want pool/apnea training.”	Pool Freediver
“I want to become a certified open-water freediver.”	Freediver
“I already have Freediver and want 30 m training.”	Advanced Freediver
“I already train seriously and want performance-level skills.”	Performance Freediver

How to Choose an SSI Freediving Instructor

Do not choose entirely based on course price.

The instructor will have a much greater impact on your experience than a small difference in cost.

Look for someone who:

Explains safety clearly
Does not pressure students to reach depth
Adjusts training to individual progress
Understands equalization
Gives useful technique feedback
Runs organized buddy procedures
Creates enough recovery time
Makes it comfortable to say “I don’t want to go deeper”

A good freediving instructor does not make you feel brave.

They make you feel informed.

What Should You Ask Before Booking?

A few questions can prevent surprises:

Which exact SSI certification will I receive?

How many pool and open-water sessions are included?

Is equipment included?

Are entry or boat fees included?

Where does the depth training happen?

How many students are in the group?

What happens if I cannot complete a depth requirement during the scheduled course?

Are additional sessions available?

What medical paperwork is required?

What certification agency is actually issuing the card?

That final question matters especially if you found the course through an article about SSI freediving.

Do not assume.

Best Time to Take a Freediving Course in the Mexican Caribbean

Training can happen throughout much of the year, but conditions vary.

Period	What to Expect
December–April	Popular dry-season travel period with comfortable weather
May–June	Warmer water and transition toward summer
July–August	Hotter weather and warm Caribbean conditions
September–October	Greater tropical-weather variability
November	Transition toward the drier tourism season
Year-round	Pool and selected cenote training can remain possible

Ocean sessions always depend on current conditions.

One advantage of training in the Riviera Maya is the variety of environments available.

If the sea decides it has other plans, a suitable cenote or pool may sometimes provide an alternative depending on the course requirements.

What Happens After SSI Freediver?

Get experience.

This part is easy to overlook because certifications make progression look like a staircase:

Freediver.

Advanced.

Performance.

Done.

Real freediving does not work that way.

SSI itself requires logged sessions before entering its higher-level courses: six sessions before Advanced Freediver and thirty before Performance Freediver. Divessi

That requirement exists for a reason.

You need time to practice:

Equalization
Finning
Buddy safety
Relaxation
Turns
Surface recovery
Different conditions

Your next course should build on experience.

It should not replace it.

Does MExplor offer SSI freediving?

MExplor’s currently published certification products show AIDA courses and general freediving training rather than specifically advertised SSI courses. Travelers who specifically need an SSI certification should confirm the certifying agency before booking. MExplor Travel

SSI Freediving Is About More Than Depth

It is easy to look at the SSI pathway and see numbers.

20 meters.

30 meters.

40 meters.

But those numbers are not really the point.

Good freediving progression happens when a diver becomes calmer, safer and more efficient.

Equalization becomes easier.

Movement becomes cleaner.

You stop wasting energy.

You become a better buddy.

You understand when to continue a dive and when to turn around.

Eventually, deeper diving may follow.

That is very different from forcing yourself toward a number because the certification table says it exists.

The best SSI freediving course is therefore not the one that gets you deepest as quickly as possible.

It is the one that gives you the skills to keep exploring safely long after the course ends.

Learn Freediving in Mexico With MExplor

If your goal is to combine formal freediving training with an actual underwater adventure, MExplor offers freediving certification and training in the Mexican Caribbean, including pool, open-water and cenote experiences. Its current public certification options include AIDA courses rather than specifically advertised SSI certification. MExplor Travel

That makes the region especially interesting if you care less about collecting a particular agency logo and more about learning the skills in environments you actually want to explore.

Train in controlled water.

Develop your technique.

Take those skills into a cenote or the Caribbean.

Then use freediving for what it was meant for:

exploring more of the underwater world on a single breath.
