For the first time ever, PFI is making their Intermediate Freediver manual available to the general public.  

Inside the 160 page digital manual (that is used for our flagship Intermediate Freediver course) you will get information on the following subjects that has helped 7 of our instructors achieve over 23 World Records.  

  • Freediving Equipment
  • Safety & Problem Management
  • Proper Breathing Techniques
  • Physiology of Freediving
  • Physics of Freediving
  • Psychology of Freediving
  • Training Exercises
  • Appendix (Equalizing Workshop, Packing, Reverse Packing, O2/CO2 Tables and Glossary of Terms)

Nothing beats taking the course from a PFI Instructor but this is the ultimate collection of Freediving information and techniques that will help you understand more about the recreation and sport of breath-hold diving.

The digital manual is viewed using the Locklizard app.  You will receive an email from Locklizard with download details as well as two (2) licenses so you can install and view on up to two different devices.  This is compatable with PC, MAC, iOS and Android.  You can not print this manual.  if you want a paper copy please purchase the paper version.

You can also purchase both paper and digital at special pricing ($44.95 for both)!

    For anyone who loves freediving this is an invaluable resource. It is truly the foundation of knowledge for the sport. and an invaluable reference to build upon. Since it is available to the public in print and digital form my recommendation is to have both. Instructor or student, this is the freediver's Bible which should be at hand. Thank You PFI for making this available to all my students.
