Your Freediving instructor - Jon Ammerman

Single Breath regularly offers Freediving Instructors International (FII) Level 1 classes on the Island of Maui Hawaii. These classes are typically scheduled monthly. FII level 1 curriculum is an accredited technique focused program. Students are presented with the absolute latest in freedive knowledge, modern safety, and methodology. Single Breath courses are offered in strict adherence to the industry leading FII standards. Passing students will receive an internationally recognized certification card.

Single Breath is a freediving school started on Maui by Jon Ammerman - a competitive freediver who took second place at the US pool national championship in 2011 and regularly trains with champion divers from around the world. Jon Ammerman received his FII instructor certification directly from 13 time world record holder Martin Stepanek.

The primary focus of Single Breath is on freediving purely as a sport and yogic / meditative practice. Even though the course material is standardized the approach to subject matter is from that perspective.

Single Breath aims to broaden freediving participation by bringing modern dive and safety practices for this amazing sport to Maui.

Other FII classes including level 2 freediver and Waterman Survival classes are hosted by Single Breath and taught by guest instructors. These classes are scheduled as special events. Private level 1 classes are available upon request.

What you can expect from the Single Breath FII Level 1 freediving class

Level 1 introduces students to the techniques, equipment and safety practices required to properly engage in freediving activities. This is the class that provides divers with a foundation for the sport. By thoroughly understanding and demonstrating these fundamentals divers will be able to go deeper, stay longer, gain additional comfort/enjoyment, and provide correct safety while in the water.

Many level 1 students enter the class as excellent and seasoned spearfishermen. Even if you consider yourself a strong diver who is in the water often, in all likelyhood Level 1 is still the class for you.

At the end of the course passing students will receive an internationally recognized certification card issued by Freediving Instructors International.

Level 1 or Level 2 class

Level 1 certification is now a requirement for enrollment in a FII Level 2 class. It is my opinion that even as someone who regularly freedives, Level 1 is the correct class for you. By providing a strong foundation in the fundamental skills, students completing Level 1 have the required techniques to finish and pass the challenge of a level 2 course. Additionally divers who have mastered the techniques presented in level 1 can focus on learning the more advanced techniques presented in level 2 and better realize the full potential of that class.

Level 2 class

Level 2 classes are not directly taught by Single Breath. They are not regularly scheduled on Maui.
Single Breath will arrange level 2 classes based on demand. Level 2 classes are taught by visiting instructors. Level 2 class offerings on neighboring islands are listed on the FII Website. If you are interested in organizing a FII Waterman Survival or Level 2 class on Maui please send an email with your interest and qualifications.

Freediving without proper training and direct qualified supervision is a risky behavior. Seek training from an active FII certified instructor before engaging in any Freediving or Apnea (breath hold) activity. Only participate after completing and passing a freediving course and under the direct supervision of an equally trained safety diver. Only participate within the guidelines of your certified training level.

A list of active FII instructors for your region is available online at: http://www.freedivinginstructors.com/

Nothing on this website is intended as instruction or encouragement to engage in Freediving outside of an FII freediving certification class.
